This is the custom in-ear monitor (CIEM) resource thread with a collection of review summaries for many of many CIEMs with links to full reviews as well as quite a bit of information. I complied this resource since CIEMs have poor resale value and I could not find a resource that compared more than 5 CIEMs, so my full reviews have comparison sections. Some CIEMs sound better from various source components, so I also have source matching in my full reviews, so check them out. Please also check out things to consider when reading a review, mine or others. So many people buy based off the driver count or because someone else gave vague praise, but I feel the most important factor in buying a CIEM is choosing the sound signature you prefer because after you get over the initial honeymoon stage, you have to like the sound you invested in. If you don't know your preferred sound signature, it may be worth buying some universal IEMs before jumping into custom IEMs, and |joker|'s multi-IEM review thread is an excellent resource for what is out there in the world of universals, and he has also reviewed some CIEMs I have not.
Don't miss my multi-portable amp review thread and if you want aftermarket cables, check out my custom in-ear monitor cable review thread.
So, if you are a musician, studio engineer, audiophile, music enthusiast, or just someone that wants isolation and great sound from a portable option, read on. Please ask questions in this thread and your question will be answered!

Custom IEM Summary Chart - Quick info for a starting point in your custom IEM search sorted by price. This should be the first thing you read and try to match keywords with what you are looking for, as well as similar sounding headphones. It is very important to know what sound signature you like will be getting from your CIEM as you will get used to the technical performance and the sound signature will determine your enjoyment of the CIEM. Also see my write-up on the Rooth lineup.
* These are the similar in sound in one way or another, but overall they are generally fairly different and don't have the weaknesses of the lower end products. This should used as a starting point to figure out which custom IEMs fit the sound you are trying to find. Read the reviews for additional information of what you think fits your preferences.

Notes on below information: the below summaries are provided to help you narrow your choice down, but links to additional information should be read for the complete picture. When frequency response charts are provided, they may not be easy to compare due to different configurations. The treble will more than likely be at least somewhat different due to the interaction in the ear, and the bass weight is dependent on note sustainment/decay. If you have any question, please ask.

[size=10.0pt]Earsonics EM3 Pro[/size]
France
[/td] [td=rowspan:2] 744,15€ excl tax ($1012 USD)
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2, colspan:2] Source Matching: - HiFiMan 601 matches great with the EM3 Pro, taking it to another level musically. - HUD-MX1 (OPA1611 op amp) headphone out is close to the 601 but lacking the extra liquidity of the 601 - Modded iPod -> Pico Slim is a nice match that has great resolution with a little colder sound. - Clip+ roughens the edges slightly and has a darker presentation than the other sources, causing the EM3 Pro to lose some of its magic - 801: Not the match I thought it would be considering the performance of the 601, lacking the fluidness to the presentation.
[/td] [td=colspan:5] With Whiplash Elite TWag v2 OM Cable: The Whiplash Elite TWag V2 cable improves the EM3 Pro in many ways including a wider and more precise presentation of space to taming the mid-bass just the right amount which increases the clarity and results in a faster sound when called for. I really didn't care for the paring of the Clip+ and the EM3 Pro with the stock cable, but with the Elite, that has changed and the Clip+ has never sounded better! The cable makes the most difference with tracks that have a large presentation of space, are warm, complex passages, and/or have a fast attack. The cable makes very little to no difference with smaller presentations, simple passages, and/or lean sounding tracks.
[/td] [td=colspan:5] Keywords: 3D, ambiance, warm, thick, powerful, mid-bass, relaxed treble [/td] [td=colspan:5] Summary: Recreation of the ambiance of a presentation is excellent, when the information is in the music such as live recordings with natural instruments that are not amped or well mastered acoustic tracks. (Some of the tracks that perform exceptionally well are anything by Balmorhea, Morphine, Danilo Perez, Amandine Beyer's Four Seasons, etc.) The presentation is thick, rich, warm, liquid, natural, and organic making the EM3 Pro very musical and enjoyable to listen to for hours. The focus is the mids, and the lower mids to be specific, along with a laid back treble that still can portray great detail and bass has great weight and natural decay but not the most textured. It also has speed for metal, bass weight for R&B, D&B, and bass heavy genres, and good treble extension, but really excels . The EM3 Pro adds the 'al' to musical.
[/td] [td=colspan:5] If you like: the SM3 (EM3 is brighter but has a slight upper midrange dip in comparison), IE8, Miles Davis, LCD-2 (EM3 is a little darker) or a warmer, darker sound and listen to acoustic music that is well mastered you will more than likely appreciate the EM3 Pro

[size=10.0pt]Earpower EP-10 Plus[/size]
Italy
[/td] [td=rowspan:2] 700 € + shipping ($953 USD)
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2, colspan:2] Source Matching: Note: I can get used to the sound, but typically the EP-10 Plus has too much mid-bass that needs to be EQed out for me to enjoy it. No EQ: Neutral/cold sources are best to me such as an iPod -> Pico Slim, iPhone, or the RoCoo. EQ: EQ in Winamp: -12 dB @ 800 Hz, + 3 dB @ 12K -> HUX-MX1 = great open and spacious sound that allows the treble to come through and show it is very good modded iPod 5.5g -> Pico Slim -12 dB @ 800 Hz = pretty close to the HUD-MX1, allowing the veil to be lifted and the quality of the sound to come out.
[/td] [td=colspan:5] Notes: EQ of -8 dB at 800 Hz in rockbox transforms these from not very listenable to fantastic!Sergio is supposedly working on tuning the EP-10 Plus with less mid-bass, which would make the EP-10 Plus much better and definitely something to consider.
[/td] [td=colspan:5] Keywords: warm, spacious, thick, enhanced bass, forward projection, mid-bass, veiled [/td] [td=colspan:5] Summary: When I wear these I get the impression I am wearing headphones, not IEMs due to the portrayal of space that is almost the size of my LCD-2. The bass from the dynamic woofer is exceptionally deep, textured, with great refinement that has all the power you could want. Unfortunately, in the current form, the EP-10 Plus is too warm and veiled for my taste with all by one of my sources without EQ. When EQed, they start to act more like an expensive custom that has better than custom presentation size. The short sound tube and open back do not give good isolation, the shape and fit are not the standard, and the cable isn't the greatest, however, when EQed the sound is amazing. Sergio did say he could tune each design to the users desire, but it will take time; I am still waiting to hear back from him, and the wait could be an eternity!
[/td] [td=colspan:5] If you like: headphones that have a warm, somewhat dark presentation such as the SM3, HD650, LCD-2 to an extent, IE8, etc. you may like the EP-10 Plus

[/td] [td=rowspan:2] 550 € in EU, 450 € outside EU ($582)
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2, colspan:2] Source Matching: - iPhone 3G interestingly enough is a very good match that has a mic/remote for iPhone use! The sound is a little more exciting than with the other sources. - iPod -> Arrow 12HE good sounding combo with the ability to boost the bass, although I have grown to appreciate the presentation without - 601 sounds good, but there is noise during quite passages/between songs - 801 adds a naturalness to the sound that makes the Fabs sound slightly more organic and textured - 801 -> Pico Slim: Amazing combination that makes the Fabs sound similar to the SE 5-way in sound signature and somewhat closest in presentation, but still falling short in the treble sparkle/extension, ultimate resolution, and last bit of dynamics.
[/td] [td=colspan:5] Options: Cables with mic/remote for iPhone or Nokia phone; give your own cable; cable exit for wearing over-the-ear; stainless steel shell (900 €); coming soon: stranded silver wire (200 €)
[/td] [td=colspan:5] Keywords: natural, neutral, mid-forward, realistic, somewhat dry, relaxed bass, relaxed treble, 3D, spacious [/td] [td=colspan:5] Summary: You want balance and ultra comfort/convenience in your custom, look no further than the Fabs. Not overly warm or lean, not overly bright and not dark, with a relaxed yet detailed and never offensive presentation that give you a fantastic 3D presentation from the front of the auditorium perspective. Powered by an iPhone, they really shine and bring whatever is in the song to the table and nothing more. With their wide space they do pretty much every genre right, from classical to classic rock, acoustic to electronics, they present wonderful music!
[/td] [td=colspan:5] If you like: The DBA-02, SA5000, e-Q7, or anything flat but with great deep bass extension the Fabs will be a nice upgrade for you. If you want a neutral and inoffensive presentation, the Fabs are worth a try. [/td] [td=colspan:3] Links: My Full Review; Comparison with ES3

[size=10.0pt]Kozee Solutions Infinity X3 [/size]
[size=9.0pt](w/ executive option)[/size]
USA
[/td] [td=rowspan:2] $620 (impressions included)
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: The quality of the source is important, and they pair best with a lean/neutral source. They pair very well with the HUD-MX1 with OPA1611 and the modded iPod 5.5g with all 3 of my amps. They don't pair very well with my 801, as the warm source makes for a too warm presentation for my taste.
[/td] [td=rowspan:2] Listening Volume Performance:The X3 performs well from quite listening levels, being a better performer in the bass than the EM3 Pro and Fabs at very low listening volumes. Performance is good throughout the volume range, not changing as the volume increases.
[/td] [td=colspan:5] With Whiplash TWag v2 OM Cable: The TWag cable, while improving the treble slightly, doesn't make much of a difference with the X3. This is more than likely due to the slight grain which overshadows the improvements of the cable.
[/td] [td=colspan:5] Keywords: punchy, dynamic, mid-forward, spacious, enhanced bass [/td] [td=colspan:5] Summary: The Kozee Infinity X3 has a lush, rich spacious, forward presentation that I find very enjoyable for casual listening as well as using while working or working out. The bass hits hard and deep with good texture, speed, and sustained note decay while the mids are presented in a forward way. The treble is emphasized as well as the rest of the spectrum, which fits with the rest of the spectrum rounding out the sound signature. There is a slight grain on some vocal tracks compared with my other customs and an edge to the presentation gets more apparent with lower quality sources. I found the presentation great for pop and electronic music and is great for letting my music inspire me when I am focused on something else such as work or working out. If you like bass heavy presentations and want the benefits that customs provide, the Infinity X3 is worth consideration.
[/td] [td=colspan:5] If you like: enhanced bass, warm universals with forward mids (SM3, Miles Davis, SE535 etc. however the X3 has more treble), listen to any sort of pop today (pop, rock, R&B, rap, etc) or electronic, the X3 may be a good choice for you. Or, if you are a bass head, the X3 may be for you! [/td] [td=colspan:3] Links: Original Kozee thread; My Full Review

[size=10.0pt]Kozee Solutions TF10 Universal Reshell [/size]
USA
[/td] [td=rowspan:2] $255 (TF10 - $130, reshell $90, cable $35)
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2, colspan:2] Source Matching: Clip+: Plenty of bass and treble with the typical recessed TF10 mids; fun sound, although the level of detail is a step down with smoothed treble iPhone 3G: Sounds different than the Clip+, and not necessarily in a good way. First, the treble isn’t as smooth (even though is seems a little smeared on theClip+, that is replaced with roughness). The slightly mid-forward iPhone does help the mids, but the bass seemed a little on the weaker side. Rocoo: Leaner cleaner presentation than the clip+ that has less bass impact and makes the TF10 sound more balanced. 801 (DAC) -> Pico Slim: takes the TF10 to a new level of refinement while opening up the soundstage, expanding it in all directions. Mids don’t seem as recessed vs the Clip+ 801 (DAC): Warmer and less dynamic sounding compared with the 801 -> Pico Slim setup. iPod -> Arrow: while not as spacious as the 801 -> Pico Slim, there is improved clarity in the upper registers, although it isn’t necessarily as smooth or refined. The lower end is a little more boomy.
[/td] [td=colspan:5] With Whiplash TWag v2 OM Cable: Not much difference other than the overall sound is a little crisper and the treble, while still being sharp with S's is slightly better. I was surprised the mids weren't brought forward, but maybe that is because the TF10 has been reshelled.
[/td] [td=colspan:5] Keywords: V shaped, enhanced bass, enhanced treble, wide soundstage [/td] [td=colspan:5] Summary: If you have a TF10, like the sound signature, which is V shaped and want to improve fit/comfort along with possibly improving the deep bass vs. your universal fit (I say possibly because the universal fit is different for everyone) while adding a more ergonomic cable, reshelling will give you what you want.
[/td] [td=colspan:5] If you like: The universal TF10, this is much more comfortable and easier to fit. [/td] [td=colspan:3] Links: Original Kozee thread; My Review & comparison with stock TF10

Spiral Ear SE 5-Way Reference
Poland
[/td] [td=rowspan:2] 1069 € + shipping ($1361 USD as of 5/15/12) (999 € for permanent cable)
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2, colspan:2] Source Matching: The 5-way isn’t a sensitive CIEM, but entry level sources such as the Clip+ can still drive it quite well and show off the advantages over lower cost IEMs. But the 5-way will improve as you move up the quality scale with high end DACs/DAPs, adding to the presentation space and transparency while recreating more micro-detail. Amps can help the sound even more as the 5-way takes well to amping, especially in the bass region where a good amp can show off the bass capability of the 5-way.
[/td] [td=colspan:5] Keywords: ultra high resolution, 3D, power, musical, rich, tonally accurate, natural, dynamic, detailed, rich, realistic, natural, powerful, extended frequency response, spacious, liquid, transparent, ambiance recreation, chameleon [/td] [td=colspan:5] Summary: With a natural, organic sound the Spiral Ear SE 5-way Reference sets new standards for me in many categories including resolution, transparency, bass capability, treble extension, and treble quality. On top of that, the 5-way changes its sound signature with each track, bringing out the mastering differences in position, warmth, and other characteristics, making it difficult to pinpoint the sound signature. Tonally the 5-way wouldn’t be considered bright but not lacking treble, however don’t look for clarity through brightness, and while the resolution and detail are present, they aren’t pushed to the front.
The presentation space is large and has a rectangular soundstage shape vs. the traditional oval, with the ability to project both forward and out at the same time quite well. The attack and decay are exceptional which result in a very natural note and the ability to recreate speed and power. Overall, the 5-way is a very neutral and transparent CIEM that performs at an extremely high level and should be a consideration for those that aren’t looking for a bright sound signature.
[/td] [td=colspan:5] If you like: to hear more micro-detail than you more than likely have heard and have music with that information, if you want treble that extends all the way up, if you want great bass with incredible tightness, texture, and accuracy while also having very good note decay, and/or if you want to have better isolation the SE 5-way is an excellent choice. The presentation is similar to the UM3X/SM3 but the frequency response is much flatter. [/td] [td=colspan:3] Links: Spiral Ear 5-way full review; original Spiral Ear thread

Thousand Sound TS842 China
[/td] [td=rowspan:2]
[/td] [td=rowspan:2, colspan:2] Source Matching: There isn't a huge difference between sources with few exceptions. If you have a Clip+ to drive the TS842, you will probably be very happy. All the steps up produce more enjoyable sound, but not by a large margin. While the 801 is the most detailed of the sources I used to review the TS842, it wasn't my favorite. I liked the sources that smoothed the treble out a little such as the iPod->Arrow and the HUD-MX1 as well as the Clip+, although there was a difference in detail. But, if you are using it for less than ideal conditions, such as in a noisy environment or while focused on something else, it doesn't make a big difference and will likely not be noticed. The TS842 is easy to drive and has thunderous bass from just about any source! More info
[/td] [td=colspan:5] With Athena (V 1.1) and Crystal cables: The Crystal cable ($41.85 shipped) improves the clarity across the spectrum while increasing the speed of the bass attack and slightly cleans up the treble, offering an overall improvement in the sound. The Athena cable ($86.85) was a pleasure to use as the edge, which was accentuated by the treble peaks, was pretty much removed while improving imaging and overall presentation. To me the Athena cable is a great match with the TS842 taking the sound up a notch and making the TS842 more competitive with higher priced custom IEMs. Check here for more information. [/td] [td=colspan:5] Keywords: Textured bass, sub-bass ability, V shaped, analytical, bright, detailed
[/td] [td=colspan:5] Summary: The TS842 has a lot to offer for those that like the TF10, want bass (dynamic, reverberant bass) with the Ety sound in the mids on up, or just want a fun sounding slightly aggressive custom (and a hybrid at that) that won't break the bank. The bass is fantastic as it has the ability to reproduce any type of bass well and sound like the very best dynamic universal IEM if not better while offering good refinement and quality across the rest of the spectrum. If you like a more laid back presentation, want a custom IEM, have around $500 to spend and want exceptional build quality to go along with the great sound quality for the price, the TS842 will be a great purchase. [/td] [td=colspan:5] If you like: Great bass reproduced by dynamic drivers and like the Ety sound in your mids/treble; you like the TF10 but want better bass, a smoother presentation, better detail, wider soundstage and just all around better sound the TS842 is for you! The TS842 does great with all genres, however it is best with electronic (trance, D&B, house, etc.) and pretty good with classical music. [/td] [td=colspan:3] Links: Pictures; My Full Review

Rooth LS8
China
[/td] [td=rowspan:2]
[/td] [td=rowspan:2, colspan:2] Source Matching: The Clip+ is a great match for ultra portability and going from there, adding a more detailed DAC section in the source chain will result in marginal improvements. Amping with the right amp will further improve the experience. Best source: 801->Stepdance Best desktop: HUD-MX1->Stepdance
Best portable: Clip+
[/td] [td=colspan:5] With Whiplash TWag v2 OM Cable: The TWag cable tightened the bass and increased the dynamics slightly as well as slightly changed the midrange presentation, adding clarity and more front-to-back space. However, with some tracks I found the soundstage size to sound a little odd and other songs the midrange frequency response was a little less impressive than with the stock cable. I am torn here as there are some slight improvements, but other aspects are decreased. The TWag does look better than the stock cable, but ergonomically the stock cable is slightly ahead of the TWag due to the flexibility. With Beat Audio Supreme Rose Cable: The Supreme Rose performed similarly, but to a lesser extent than the TWag but a more intimate presentation. The presentation issues were still there, but to a lesser extent with the Supreme Rose. It also looks better than the stock cable and ergonomically is on par with the stock cable. With Beat Audio Cronus Cable: Summary: This cable comparison was a difficult one because the possible changes are very small. I think that due to the sound signature of the LS8, the cables do slightly improved the strengths of the LS8 with little change, and arguably a positive change overall since they seem to change the midrange presentation slightly. When I used the cables with a less detailed source than my 801->Stepdance combo the differences seemed to disappear.
[/td] [td=colspan:5] Keywords: punchy, dynamic, bright, liquid, detailed, exciting, extended, bass enhanced, speed
[/td] [td=colspan:5] Summary: The LS8 is an amazing sounding custom IEM with an emphasis on the midrange, specifically the upper midrange, but does not lack in the bass or treble departments. Bass is powerful with great impact and reverberation while treble is extended and very flat resulting in a very non-fatiguing sound with ultimate detail and fantastic imaging. Source matching is important as with some songs S’s became slightly sharp in contrast to the exceptional smoothness the LS8 usually exhibits. The box it comes in is impressive, unfortunately the carrying case was a letdown. The two year warranty is nice and the build quality is impeccable. If you like a mid-forward presentation that puts you front row, center bringing incredible detail to you, the LS8 is a great choice. Just pick your source wisely! [/td] [td=colspan:5] If you like: The CK10, DBA-02, or other TWFKs, you will probably like the LS8 with added warmth and bass power. Truly a flagship product that produces amazing sound.

Minerva Mi-3
UK
[/td] [td=rowspan:2] £395 ($615)
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: The Mi-3 is source dependent and really benefits from an amp or a source with more power. If you want more bass, an amp like the Arrow with a bass boost or the Stepdance that can control the drivers and enhances the bass standard will be good fits. Depending on your preferences and what you are used to, the Mi-3 will sound find from an iPhone, but using it with a good amp does raise the performance of the Mi-3.
[/td] [td=rowspan:2] Listening Volume Performance : The sensitivity of the Mi-3 is lower than all my other customs in a similar price range and is much more dependent on the source and tracks than any other IEM I own. The low volume performance is dependent on the source and can range from poor to average. The bass driver needs power to get going and DAPs with weaker outputs (Clip+ for example) don't perform as well as an amp.
[/td] [td=colspan:5] Keywords: rich, warm, forward projection, liquid, 3D, bass neutral
[/td] [td=colspan:5] Summary: If you want a comfortable, affordable custom IEM that offers amazing smoothness with better than acrylic isolation, the Mi-3 is an attractive product. Included accessories are top notch and build quality is very good, although the cable has memory and gets tangles easier than the typical twisted cables. Minerva customer service is great and when combined with build quality instills confidence. The Mi-3 presents music with a great smoothness that I have not heard within the price range and can be very enjoyable when using a source that can provide some power. But be prepared to find the right source to get the most out of the Mi-3, and the bass response isn't going to rattle your teeth. Overall the Mi-3 has a lot to offer and will make many owners very satisfied.
[/td] [td=colspan:5] If you like: thicker, smoother presentations the Mi-3 is hard to beat for the price. The Mi-3 does well with acoustic music such as guitar, symphony, vocals, jazz, and most rock for example, but can still work with other genres, even metal. [/td] [td=colspan:3] Links: My full review

M-Fidelity SA-43 (formerly Starkey Norway)
Norway
[/td] [td=rowspan:2] NOK 5648 ($1014)
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2, colspan:2] Source Matching: Quality of the source is very important with the SA-43 in order to achieve the potential of the SA-4. If you are only going to use low end DAPs or your phone, you might as well look elsewhere, not that the SA-43 is bad per se, but the playing field was leveled. Basically, the SA-43 scales well and can perform at a very high level when fed from a high level source.
Great matches: HiFi Man 801, modded iPod -> Pico Slim, Anedio D1 DAC So/so matches: J3, RoCoo, HUD-MX1 Very poor matches: iPhone 3G (stay away), Clip+

[/td] [td=colspan:5] Keywords: very spacious, 3D, realistic, ambiance, enhanced bass, neutral treble, natural tone [/td] [td=colspan:5] Summary: The SA-43 is special in the way it recreates the space of a presentation along with stellar transparency, putting everything together to make not just music but an experience. Isolation is also top notch as the silicone filled acrylic shell isolates slightly better than my two pure silicone custom IEMs. Not only that, you can customize the frequency response to your liking with a switch that controls the extra bass driver and a switch to add midrange "presence." Spatial presentation is top notch in size, proportions, instrument placement, and timbre. Add great dynamics, speed, tone, and pace and all genres of music sound captivating and involving. Detail levels, are right around the middle of the pack; there are some that do better and some that do worse. It is very important to note that the SA-43 requires a good source or you will lose the great space and some dynamics resulting in a more average performance. The included accessory pack is extensive however I am not very fond of the carrying case Overall the SA-43 is an incredible custom IEM!
[/td] [td=colspan:5] If you like: When used with a good source the SA-43 is great for those that want great spaciousness and transparency. The switches allow for customization of the bass and midrange presentation, so the SA-43 is very versatile! [/td] [td=colspan:3] Links: SA-43 vs. JH13 vs. JH16; My Full Review Here

M-Fidelity SA-12 (canal version) (formerly Starkey Norway)
Norway
[/td] [td=rowspan:2] 3320 NOK ($600)
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: Best matches include the iPhone 3G, HiFi Man 801, when amped with the Stepdance, and the Anedio D1 DAC.
[/td] [td=rowspan:2] Listening Volume Performance: Very good performance at low volumes, the bass is at full power without much power, resulting in the sound not changing much at different volume levels.
[/td] [td=colspan:5] keywords: tapering up frequency response (emphasis increases as the frequency response increases), extended, liquid, warm, bass neutral [/td] [td=colspan:5] Summary: One of the few small form factor custom IEMs on the market, the SA-12 has a lot to offer including a sound I wasn't expecting from the TWFK driver. The accessory pack is thorough although not perfect, but better than average. Build quality is great and isolation isn't bad for a canal only custom IEM. On the sound front the SA-12 has an overall lean toward an analytical and bright presentation but the thickness of the note and warmth give the SA-12 a richness not usually found with the other characteristics, not to mention acceptable bass rumble. The SA-12 can't quite keep up with the detail or extension of the competition in the price range, but I can see many people enjoying the overall combo of the rich yet analytical and close to neutral presentation.
[/td] [td=colspan:5] If you like: A presentation that is between relaxed and analytical with warmth, this sound will be very pleasing. Recommended for many genres but not for genres where soundstage should be large such as classical, but the bass reverb is great for pop and electronic music.

Jerry Harvey Audio JH16
USA
[/td] [td=rowspan:2] $1149 + artwork ($100)
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: The JH16 doesn’t need much power to be driven well and headphone outputs from some DAPs sound quite good with the JH16, even if missing some of the micro-detail in the instruments. Due to the very high sensitivity of the JH16, sources with an analog volume control such as the 801 and HUD-MX1 had some issues at my normal low to very low listening volumes due to a channel imbalance which went away at moderate volume levels.
[/td] [td=rowspan:2] Listening Volume Performance:
[/td] [td=colspan:5] With Whiplash TWag v2 OM Cable: The Whiplash TWag cable fixes the soundstage depth issue with the JH16 while smoothing the presentation, resulting in an overall improvement.
[/td] [td=colspan:5] Keywords: punchy, dynamic, analytical, bright, bass enhanced, detailed, very spacious, speed, sub-bass ability [/td] [td=colspan:5] Summary: The JH16 gives new meaning to bass with a performance that combines enhancement with dynamics, detail, punch, speed, and rumble. Instrument detail is plentiful across the spectrum with an added liquidity to the vocal range and an enhancement in the upper mids/lower treble that accentuates the clarity. Soundstage width is great and competes with/bests similarly priced custom IEMs I have heard. However the depth and height of the performance does fall short of the others, sounding compressed in comparison with tracks that are presented with a large 3D space. Music is presented in more of an analytical sort of way, so if you are looking for a thicker and more relaxed presentation, look elsewhere. Driving the JH16 is easy as a Clip+ does quite a good job and moving up the source chain doesn’t necessarily result in better overall sound except for a little more detail and possibly a larger soundstage with some music. Accessories are fine for this price point and when you use the dual case setup the JH16 will be well protected.
The JH16 is great with today’s pop, hip hop, and a wide range of electronic music where it brings out the most of many over-saturated songs adding punch, detail, space, and excitement while acoustic music with a 3D presentation may disappoint due to the soundstage presentation not having the best depth/height. For the initial target market, on stage monitoring, the JH16 does perform quite well as it pulls out the details for you to hear and if you are a singer it presents vocals with added liquidity. The ability to customize the shell with artwork is nice and I get compliments on the look of mine. If you get the JH16 be prepared for enhanced bass regardless of what you are listening to, from rap to country, even if you don’t want the enhancement.
[/td] [td=colspan:5] If you like: The JH16 is perfect for electronics and pop music! Stage performers that want to hear every detail. Enhanced bass with a neutral midrange presentation and a bright, airy treble to go with a fast and slightly anaytical sound, the JH16 fits the bill.

Dream Earz aud-5X
USA
[/td] [td=rowspan:2] $565
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: The 5X is easy to drive and as long as you are using a good amp and DAC it doesn't make a huge difference which one you actually use. When you do move up to a nice DAP/DAC/amp from something like the Clip+ or iPhone you will be rewarded with a greatly improved soundstage that is very 3D and immersive.
[/td] [td=rowspan:2] Listening Volume Performance: The 5X has adequate bass performance at very low volumes and performs within the top group of BA custom IEMs for low volume bass performance. Once the volume is at a low-moderate level the bass kicks up a notch. At louder volumes the overall sound is still very listenable and the treble non-offensive. The 5X has better than typical performance for the price range. Sensitivity is on the higher side, but not to the level of the JH16 or LS8. This helps with many sources with analog volume control issues or hiss problems.
[/td] [td=colspan:5] Keywords: liquid, transparent, enhanced bass, balanced, powerful, effortless, rich, extended frequency response, sub-bass ability [/td] [td=colspan:5] Summary: Breaking the current driver/price performance barriers the aud-5X is a very capable performer. Technically the 5X punches well above its price point, closing in on more expensive custom IEMs at double the prices. The strengths include transparency, bass capability, dynamics, soundstage proportions, and bass and midrange resolution. The overall sound is refined, liquid, a little on the warm and rich side with some bass enhancement and a brighter treble to go along with a bit of a mid-forward presentation. The coherence across the frequency spectrum is excellent with similar note thickness from top to bottom and excellent integration from the lowest notes to the highest. When compared with others in the price point, the aud-5X really doesn't have technical weaknesses. Being the aud stands for audiophile, the presentation has hit a sweet spot in the sound with the overall balance.
[/td] [td=colspan:5] If you like: A relatively balanced sound with enhanced bass. Think a JH16 with a little less enhancement in the bass and treble with a less analytical sound. [/td] [td=colspan:3] Links: Full Review Here

Ultimate Ears In-Ear Reference Monitor
USA
[/td] [td=rowspan:2] $999
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: The UERM is easy to drive, therefore an amp does little to help the sound. DAC quality and flavor will matter as the UERM is fairly transparent to the source and does scale somewhat with the source.
[/td] [td=rowspan:2] Listening Volume Performance: The UERM is a good low volume performer and has no issues with loud volumes.
[/td] [td=colspan:5] My usage: analytical, accurate, bright, neutral bass, detailed, transpaent [/td] [td=colspan:5] Summary: The UERM is what it set out to be, a reference monitor, and an excellent one at that. While not perfect when compared with similarly priced competition, it does offer a good mix of attributes that when combined result in an overall good presentation that recording engineers can use for exceptional masters. As for the audiophile audience, the UERM is a good choice for those looking for transparency and accuracy more so than a musical experience, although I can thoroughly enjoy music with the UERM. The accessories are very nice, including the metal case which fits the UERM perfectly and offers great functionality with ease of use and a good look. The cable is better than other stock cables I have seen and the shell connector is protruding instead of flush or recessed resulting in a very solid and durable design.
The UERM does present high levels of detail within excellent soundstage recreation both in the size and shape of the space, being among the best I have heard in this regard. The overall sound is bright resulting in very good clarity, with a gently increasing emphasis on the frequency spectrum as the frequency increases, bringing the treble more forward than the mids by a bit, and the mids more forward than the bass by a bit. The drivers are well matched and sound very cohesive and the single bass driver does a fairly good job pumping out bass. While the UERM is very good for the presentation it has, the sound is an analytical one which lends to the ability to hear very good instrument detail but the ambiance of a presentation isn’t recreated they way it is with many competitors. The biggest issue I had with the UERM is that the treble can be harsh depending on the recording, and while this isn't unique to the UERM, it did occur with more songs than any other custom IEM in the price range. And dynamics, while overall good, are not quite up to the level of other $1000+ custom IEMs I have heard.
All in all the UERM has a place among the other custom IEMs I have heard in the price range as it offers a reference sound with an exceptional presentation; a combo I have not heard up to this point in a custom IEM. Combine that with the accessories and cable and the UERM stands up well with the competition.
[/td] [td=colspan:5] If you like: The TWFK dual drivers but want way more out of your sound, the UERM will give you that. The UERM does live up to the bill and would be great for studio engineers as well as audiophiles that want an analytical sound without giving up much. [/td] [td=colspan:3] Links: Full review here

Wan Xuan wx i9pro
China
[/td] [td=rowspan:2] $669 ($589 for the launch intro)
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: The i9pro has the ability to resolve more detail than the entry level DAPs such as the Clip+ and iPod, and even the RoCoo and Studio V can output, so using an 801 or decent DAC will reap some benefits. Amps also help, but to do the FST, only to a point. If an amp strengthens the bass too much the FST will cause the bass to be less controlled affecting the sound in a negative way as happened with the Anedio D1. The 801 is overall a very good match, but due to the price something such as an iPod/iPhone to the uHA-120 via LOD will be a great compromise between price and performance.
[/td] [td=rowspan:2] Listening Volume Performance: The i9pro is good at low volumes but the bass levels are lower, probably due to perception from human loudness curves. Due to the sensitivity there more than likely won't be many issues with sources that have analog volume controls. The biggest issue I have with the i9pro as far as volume is at louder volumes. For whatever reason, the driver becomes uncontrolled and when there is a lot of bass it bleeds to the midrange. This isn't an issue for me as I don't listen at volumes that will cause the issue (and I highly recommend you don't listen that loud also), but it is there if you crank the volume.
[/td] [td=colspan:5] Key words: Warm, rich, liquid, enhanced spaciousness, enhanced bass, 3D, sub-bass ability [/td] [td=colspan:5] Summary: FST technology gives the i9pro a pretty unique sound in its price range with added spaciousness to go with the sound of a dynamic driver. The spaciousness comes with enhanced bass, an overall warm presentation and a great treble quality. The level of enhancement is high with punchy and deep, rumbling bass. Detail levels are good for the price range and presented in a liquid and enjoyable way. Note decay sounds very natural but speed is average. Piano sounds amazing, D&B bombastic, and most genres sound right. Midrange tonality is on the warmer side.
But, with the good comes some issues including treble roll off at 13K which can affect air and not recreate some of the harmonics and spatial queues that give ambiance to the upper end. FST increases the bass and this can lead to the bass sounding a little uncontrolled at times, and the added spatial qualities can affect instrument placement for very spacious tracks. However, even with these issue the overall presentation of the i9pro is very enjoyable and without direct comparison you will most likely be hard pressed to hear the issues. So go ahead, rattle your brain with 14mm of dynamic driver that give you a nice spatial experience.
[/td] [td=colspan:5] If you like: Lots of bass and a spacious sound, the i9pro won't disappoint. Upgrade from SM3 and IE8; Upgrade to EM3 Pro and SE 5-way [/td] [td=colspan:3] Links: My Full Review

[/td] [td=rowspan:4, colspan:2]
[/td]
[td=rowspan:2, colspan:2]
Source Matching:
While entry level DAPs certainly don't sound bad with the NT-6, they don't bring the dynamics, excitement, or detail of the higher end hardware. When the detail level from the source (DAC) is increased there is a direct correlation to the quality of the music recreated; the NT-6 is very source transparent. It is a fairly easy to drive CIEM so other than amp sound signatures, there isn’t much difference between high quality portable amps.
[/td] [td=colspan:5]
[/td] [td=colspan:5] Keywords: neutral bass; transparent; 3D; natural, spacious, tonally accurate [/td] [td=colspan:5] Summary: Clarity, imaging, dynamics, and full range reproduction highlight the biggest strengths of the NT-6, however there are still other exceptional traits of this reference beast. The NT-6 isn't shy about pointing out flaws in other CIEMs when compared directly and doesn't exhibit much itself, which is indicative of the very high technical performance. The biggest weakness of the NT-6 is that the depth of the presentation isn't up to par with a few others in the price range, but the differences aren't too large. Bass is neutral but not lacking with the ability to recreate sub-bass rumble and pump out a solid bass performance.
Accessories are decent but not without issue. The case is very attractive but a bit small and I often had issues closing it and the NT-6 has a non-standard cable, which is microphonic so additional purchases of replacement items may be a necessity from the start. However, taking into account the sound, the NT-6 is still an exceptional value due to the high level of sound quality and build quality. If you are looking for a reference monitor and sound really matters, you have to consider the NT-6.

Earsonics EM4
France
[/td] [td=rowspan:2] 890 Euros
($1167)
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: The EM4 performs very well from entry level DAPs such as the Clip+ and there are minimal improvements as you move up the listening chain. Higher end DACs will add some additional space and detail to presentations while an amp will control the bass a bit better, but overall the gains aren't huge. There is no need to go all out with the source unless you really want to eke out every last bit of performance.
[/td] [td=rowspan:2] Listening Volume Performance: The EM4 has very good volume performance from the low end through what I consider loud. The bass drivers kick in at a relatively low level, but a bit of power is needed to really achieve what the EM4 can do in the bass region. The sound signature doesn't change from that point on up to very loud.
[/td] [td=colspan:5] Key words: warm, right, clear, bright, bass power, bass rumble, amazing vocals, imaging, airy [/td] [td=colspan:5] Summary: Tuned for the audiophile, the EM4 gives an impressive presentation, immersing you in the experience and bringing the performance right to you. The mid-forward presentation puts vocals up close and personal while giving you great tonal quality and imaging with bass that is enhanced, powerful, and visceral and treble is extended and realistic. Everything is presented in a very fluid way and thin is never a word that comes to mind with the EM4, but that doesn't prevent a bright and very clear presentation. Detail levels are very good, especially in the midrange, and with great transparency, the EM4 gets out of the way of your music.
The liquidity allows the EM4 to be very forgiving, but the side effect is a slight lowering of treble detail, and bass texturing is typically a bit lower than the competition, which is a tradeoff for the enhancement and capability. In direct comparison with many others high end CIEMs, the EM4 has a bit of a dip in the upper midrange which can lead to the sound being slightly 'off' sounding at times. However, dynamics and speed are excellent leading to a presentation that is exciting, punchy and fast while being warm and immersive; an impressive combination. The EM4 has a special sound that reminds me of the SM3 when I first heard it, but oh so much better in every way!
Overall, the EM4 gives a combination of speed and clarity with warmth and richness I have not heard elsewhere.
[/td] [td=colspan:5] If you like: The SM3 but want a brighter presentation or like the SE535 but want a more coherent presentation, the EM4 will deliver. Even if you don't like either but want a mid-forward presentation the EM4 does it in a way that is immersive and engaging with plenty of bass and an extremely high technical level of performance.

Alclair Reference
USA
[/td] [td=rowspan:2] $499
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: The Reference is not too difficult to drive and lower end sources realize nearly all the detail and space available, but improving the amp section does result in a tighter, better controlled sound. Adding an amp to your existing source such as an iPhone or Fuze will result in as good of an experience, if not better than upgrading to an expensive DAC.
[/td] [td=rowspan:2] Listening Volume Performance: The Reference has decent low volume performance, but at very low volumes the bass driver doesn’t really kick resulting in a flatter presentation. At moderate and above volume the Reference offers the full power and glory of the presentation, not having any issues at the loudest level I want to listen at for even a short period of time.
[/td] [td=colspan:5] Key words: Neutral, natural, 3D, spacious, musical, extended, warm [/td] [td=colspan:5] Summary: The Alclair Reference provides a balanced yet musical presentation that offers an impressively flat presentation with class leading clarity at a relatively affordable price of $499. Bass rumble is good for a balanced armature driver with extension down to 20 Hz, providing good texturing and control. The midrange is neither forward nor laid back with good spatial recreation; however the cohesion of the presentation is a bit below standard due to less definition in the center of the soundstage. Note thickness sounds very natural with very good attack and decay, especially in the treble region, standing out amongst its peers for the natural presentation.
The Reference can be used as just that, a reference as it has the flattest, most neutral sound that I have heard in the price range. It is, however, not quite as bright as the other ‘reference’ CIEMs, which do cost double+ and are and revealing of poor masters. Audio enthusiasts and audiophiles that are looking for a balanced, neutral sound with good capabilities that won’t break the bank should take a look at the Reference as Alclair has done an excellent job of combining musicality with reference sound, making the Reference very versatile and enjoyable.

[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: While the T1 Live! does OK with DAPs, noticeable sound improvements will be realized from amps and higher resolution DACs. The T1 Live! was designed for stage use with wireless packs, which I don’t currently have for testing.
[/td] [td=rowspan:2] Listening Volume Performance: The T1 Live! performance at very low volumes isn’t the greatest as the bass driver doesn’t fully kick in until low volumes, and is up to full speed at mid-low volumes. At louder volumes the T1 Live! can sound more congested than at lower volumes with complex tracks.

Key words: Warm, rich, organic, mid-forward, 3D, natural, no

[/td]
[td=colspan:5]
Summary:
The T1 Live! is aptly named not only for the built in microphones that works with the ACS ambient processor, but also that the sound has a natural sound of a live venue. Rich is a great word to describe the T1 Live!, and the pleasant presentation and comfort of silicone will allow you to listen all day whether you are on stage, on a train, or at home. The bass and midrange a forward while the treble is gently laid back, and all are integrated perfectly together. The soundstage is very 3D and immersive with great imaging and transparency resulting in an immersive experience, but the best thing about the T1 Live! is the vocal presentation which always sounds natural and ‘right.’
But it is not all perfect, as nothing is. The T1 Live! can sound a bit congested with complex music at louder volumes when compared with others in its class, and bass rumble is bested by the multi-bass balanced armature driver and dynamic driver custom IEMs. This is worse with lower end DAPs and improves with amps, although the T1 Live! was designed to be used with a wireless pack, which I do have for source matching. But the more natural sounding tone makes up for these shortcomings vs. much of the competition. Overall, performance is very competitive for the price, and combined with the rich and involving recreation of music, the T1 Live! is a great option stage and for the audio enthusiast.

[td=rowspan:2] DUNU DC4
Taiwan/China
[/td] [td=rowspan:2] 3000 RMB ($499)
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: The DC4 is selective about the sources that it sounds best with, which are those that are of the mid-forward type with good depth to the presentation. While more expensive sources sound better than the entry level DAPs, more expensive sources didn’t necessarily sound better than mid-priced ones since presentation matching is very important. Also, the DC4 is very sensitive and can bring out the hiss/noise in your sources more so than just about any custom IEM I have heard.
[/td] [td=rowspan:2] Listening Volume Performance: The DC4 performs well at low volumes, especially when there is a powerful source. The bass driver kicks in and is dynamic at a moderately low volume. After turning the volume up past what I consider loud listening, although many may not, the DC4 starts to become rougher and congested sounding. Again, this is at listening levels that really aren’t necessary since the DC4 isolates well, and you will damage your hearing if you listen at those volumes for any extended period of time.
[/td] [td=colspan:5] Key words: Mid-forward, l iquid, warm, rich, powerful, coherent, transparent, balanced, forgiving, 3D, imaging, presentation depth [/td] [td=colspan:5] Summary: DUNU’s first custom IEM, the DC4, is a winner in many ways providing an extremely involving and enjoyable presentation that is mid-forward, liquid, and rich. Transparency and coherence are top notch within the price range and close to CIEMs that cost double, and when paired with a synergistic source, the depth of the presentation is impressive. With a frequency response that is fairly balanced but not necessarily neutral, the DC4 is fun and quite capable in the bass response. Certain characteristics change depending on the tracks and sources, improving or reducing the listening experience, however the DC4 is quite forgiving of poorly mastered tracks.
Overall, the DC4 has a great sound signature with enhanced, capable and warm bass, a liquid midrange that is presented up-close and personal, and treble that has a nice balance between bright and dark, all leading to a very engrossing and non-fatiguing experience. The DC4 is a good starter custom IEM as it has a very enjoyable sound, it can grow with you as you upgrade your sources, and will be forgiving as you improve the quality of your music collection.

[/td] [td=rowspan:2] Listening Volume Performance: Playing loud is not a problem for the AS-1b as the 15mm driver has plenty of headroom, and moderate volumes are fine as well, but due in large part to the sound signature, low to very low volume listening results in the perception of lower amounts of bass and treble due to human loudness curves.
[/td] [td=colspan:5] Key words: Mid-forward, l iquid, warm, rich, powerful, thick, 3D, imaging, presentation depth [/td] [td=colspan:5] Summary: The AS-1b is a very capable performer that was designed for musicians, and many of the musicians I know like to EQ their equipment, which the AS-1b reacts very well to. The 15mm driver has great dynamics and can play at very loud levels if need be. The overall mid-focused sound signature has great presentation depth and nice imaging, instrument placement, and separation making for an involving presentation.

[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: The AM4 pro is very scalable: feed it from a better source chain and you will get better results. The difference between the highest and lowest performing sources is quite large and the AM4 pro is selective about the amps/sources it pairs well with.
[/td] [td=rowspan:2] Listening Volume Performance: Performance is excellent at low to medium volumes, but above medium volumes the soundstage becomes less clear and the treble becomes sharper.
[/td] [td=colspan:5] Key words: [/td] [td=colspan:5] Summary: The Ambient Acoustics AM4 pro is an exceptional performer at the price point with a relatively neutral and very natural sound that works for the stage, studio, or just enjoying music. Note decay is very realistic, the soundstage is very 3D with exceptional depth, and dynamic range is impressive, all resulting in a presentation that immersive and engaging while staying neutral but still musical. When supplied by a high quality amp, the AM4 pro can compete with CIEMs that cost double as it scales very well. However, with lower end sources and at louder volumes the clarity can suffer as complex material becomes slightly congested. Overall the AM4 pro performs admirably and will surely develop a following due to the sound quality and value.
[/td] [td=colspan:5] If you like: Balanced sound that isn't lacking in the treble region, but not necessarily bright with plenty of bass capability in a very musical and non-analytical way, the AM4 pro is great. If you have higher end sources to pair with it, the it will perform at well above it's price. [/td] [td=colspan:3] Links: My full review

NT-6 pro
Korea
[/td] [td=rowspan:2] $1,250 USD
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: The NT-6 pro changes quite a bit with different sources, so finding the right sound for you can take some trial and error. The quality of the DAC section does help with detail and resolution, but especially in achieving the presentation depth and width the NT-6 pro is capable of. For some reason the latest software for the 801 is a horrible match; however, all other DAPs/DACs I have tried don’t have the same issues. Using a good amp also helps where it comes to spatial presentation; however, the small changes to the upper midrange and treble did lead to significant tonal changes. Select your source carefully and be prepared for some trial and error.
[/td] [td=rowspan:2] Listening Volume Performance: Performance at all volume levels is quite good as the enhanced bass helps get the bass driver moving with very low volume levels and the sound signature is retained as much as it can be, taking loudness curves into account. At louder volumes, very heavy bass tracks can get a bit distorted, but I can’t listen for longer than a second of so, and can’t imagine people would have hearing in a year listening at those volumes. Even at loud volumes, there is absolutely no congestion.
[/td] [td=colspan:5] Key words: [/td] [td=colspan:5] Summary: Boasting 6 balanced armatures in a 5-way design, the NT-6 pro is very capable of amazing sound across the spectrum. The sound is on the analytical side, but with some liquidity and musicality. Both ends of the frequency spectrum are enhanced at the extremes, but the midrange is not recessed, and the sound does not have the typical warmth that comes with enhanced bass. The sound is on the quicker and punchier side with excellent dynamic range, transparency, smoothness, and plenty of speed for any genre, but still enough note decay for a natural sound. Clarity and presentation focus are in a class of their own and help present every detail within the music clearly and concisely.
While the NT-6 pro sounds good with lower end sources, carefully selecting a quality DAC and amp or DAP will result in an improved performance. From a technical standpoint, the NT-6 pro is one of the top three in performance of my custom IEM collection and I highly recommend it if you like a bright, engaging, fun, ultra-detailed and clear sound.
[/td] [td=colspan:5] If you like: Bright sound and want ultra-detail with the excitement of enhanced bass, the NT-6 pro is for you! [/td] [td=colspan:3] Links: My full review

[td=rowspan:2] Logitech Ultimate Ears Personal Reference Monitor
USA
[/td] [td=rowspan:2] $1999
[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching : While the PRM will play nice with some lower end sources, if you are going to spend on the PRM, you should have the source chain to shine.
[/td] [td=rowspan:2] Listening Volume Performance: The PRM performs well at both low and high volume levels, and everywhere between
[/td] [td=colspan:5] Key words: [/td] [td=colspan:5] Summary : Does this $2K CIEM live up to its price? First, being able to tune the sound to your preference solves one of the issues with CIEMs, which is you have to typically buy a non-refundable product to find out the true sound. If you don’t like it, you are out a good deal of money, which is why the ability to not only tune the sound, but try it before you buy is important and has a high value in my opinion, which people ask me for all the time. And when people do ask my opinion, I always recommend they buy based on their sound signature preference and usage. This feature is great.
From a performance perspective, the sound signature of my unit isn’t as important as the sound tendencies and technical performance since you can tune the sound to your liking. Technically the PRM is one of the top performers I have heard, disappearing and letting the music come through with exceptional transparency and realism. The sound is spacious and on the organic side of the spectrum, if just by a bit, and it the warmth is north of neutral. With a laid back presentation, the overall performance is the focus, not the individual instruments, although they are clear and detailed. The PRM performs at a higher level than the $1K UE IERM and up there with more expensive CIEMs I own. The Logitech Ultimate Ears Personal Reference Monitor is an exceptional product, even at its price point, due to the sound tuning feature before you buy and the sound quality you get when the customized version is delivered to you.

Click on pictures for a larger view.
Notes on below information: the below summaries are provided to help you narrow your choice down, but links to additional information should be read for the complete picture. When frequency response charts are provided, they may not be easy to compare due to different configurations. The treble will more than likely be at least somewhat different due to the interaction in the ear, and the bass weight is dependent on note sustainment/decay. If you have any question, please ask.
| Design: Solid acrylic housing (not a shell) with dual sound tubes and a recessed connector jack | Cable: Detachable with pin compatibility with Westone cables; clear/silver; cable oxidizes green over time | Accessories/Warranty: Plastic hard carrying case, cleaning tool; 1 year warranty; 30 day refit |
| Drivers/configuration: (3,2) dual bass BA drivers and single BA mid/treble driver in a 2-way configuration | Build Quality: The outer shell is very well done and bubble free, however the inner acrylic fill has bubbles along the edges resulting in a less than clean look | Isolation: average - 5/10 - the canal tips seem to taper off more than my other customs, which is probably what is contributing to the average isolation even though the shells are full acrylic |
| Sound Signature: Warm, lush sound with a slight focus in the lower mids and also in the lower treble region, although the overall frequency response is fairly flat. Presentation is like you are on stage with the instruments all around you and a relatively smallish soundstage for a custom in this price range. Ability to reproduce powerful bass.. | Sonic Strengths: Presents ambiance of natural instruments giving them amazing space, depth, texture, and realism within the soundstage. The presentation is very liquid with a captivating and never harsh presentation. The soundstage has exceptional projection in all directions with some spacious, well mastered tracks. Can reproduce large amounts of bass. | Sonic Weaknesses: Thickness is not for everyone; slight upper midrange dip makes female vocals slightly throaty; A/Bing with leaner headphones accentuates the slight veil from the warmth/thickness; bass rolls off at 30 Hz. Bass detail and texturing is not on par with others in the price range and overall detail isn't the best. |
| Listening Volume Performance: The EM3 Pro is at its best when the volume is at a low-medium volume or above. At lower volumes the power and dynamics are slightly subdued | ||

[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2, colspan:2] Source Matching: - HiFiMan 601 matches great with the EM3 Pro, taking it to another level musically. - HUD-MX1 (OPA1611 op amp) headphone out is close to the 601 but lacking the extra liquidity of the 601 - Modded iPod -> Pico Slim is a nice match that has great resolution with a little colder sound. - Clip+ roughens the edges slightly and has a darker presentation than the other sources, causing the EM3 Pro to lose some of its magic - 801: Not the match I thought it would be considering the performance of the 601, lacking the fluidness to the presentation.
[/td] [td=colspan:5] With Whiplash Elite TWag v2 OM Cable: The Whiplash Elite TWag V2 cable improves the EM3 Pro in many ways including a wider and more precise presentation of space to taming the mid-bass just the right amount which increases the clarity and results in a faster sound when called for. I really didn't care for the paring of the Clip+ and the EM3 Pro with the stock cable, but with the Elite, that has changed and the Clip+ has never sounded better! The cable makes the most difference with tracks that have a large presentation of space, are warm, complex passages, and/or have a fast attack. The cable makes very little to no difference with smaller presentations, simple passages, and/or lean sounding tracks.
[/td] [td=colspan:5] Keywords: 3D, ambiance, warm, thick, powerful, mid-bass, relaxed treble [/td] [td=colspan:5] Summary: Recreation of the ambiance of a presentation is excellent, when the information is in the music such as live recordings with natural instruments that are not amped or well mastered acoustic tracks. (Some of the tracks that perform exceptionally well are anything by Balmorhea, Morphine, Danilo Perez, Amandine Beyer's Four Seasons, etc.) The presentation is thick, rich, warm, liquid, natural, and organic making the EM3 Pro very musical and enjoyable to listen to for hours. The focus is the mids, and the lower mids to be specific, along with a laid back treble that still can portray great detail and bass has great weight and natural decay but not the most textured. It also has speed for metal, bass weight for R&B, D&B, and bass heavy genres, and good treble extension, but really excels . The EM3 Pro adds the 'al' to musical.
[/td] [td=colspan:5] If you like: the SM3 (EM3 is brighter but has a slight upper midrange dip in comparison), IE8, Miles Davis, LCD-2 (EM3 is a little darker) or a warmer, darker sound and listen to acoustic music that is well mastered you will more than likely appreciate the EM3 Pro

| Design: Thermoplastic shell with an open design and shallow canal length; single large nozzle with internal tube for BA | Cable: Not detachable; cable from ear bud which is OK, non-microphonic, doesn't tangle easy, and is lightweight. Memory wire added. I do have durability concerns with the cable. | Accessories/Warranty: Soft carrying bag. 1 year warranty; 30 day refit |
| Drivers/configuration: (3,3) Single dynamic bass driver; dual BA in a 2-way configuration for mids/treble | Build Quality: The shell is solid, but the memory wire seems prone to breaking where it exits the shell; the ear bud seems attached well, but looks like it could be a weak point. | Isolation: limited - 1/10; open back combined with shallow insertion |
| Sound Signature: Headphone spaciousness with a lot of bass and especially mid bass, leading to a veil across the mids and treble resulting in a lack of detail in the treble and causing the upper mids/treble to sound recessed; when the mid-bass is EQed down, they balance out and the veil lifts while keeping the headphone like spaciousness, but still lacking the ultimate detail of the others. | Sonic Strengths: Incredible space that is nearly as large as the LCD-2 full sized headphones and envelopes you with the IEM coherence between left and right, making you feel like you are at a concert; incredible bass detail, impact, texture, and quantity, with nearly the quality of the LCD-2 | Sonic Weaknesses: Way too much warmth puts a veil on the sound unless EQed; treble detail level not as good as my other customs; mids are subdued by the bass; lack of isolation (and looks) reduces the effectiveness of these in louder public situations |
| Listening Volume Performance: The EP-10 Plus is great at lower volumes due to the loudness curves and the bass driver low volume performance. At moderate and louder volumes the extra mid-bass was problematic and caused mid-bass overload. The EP-10 Plus is extremely sensitive. | ||

[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2, colspan:2] Source Matching: Note: I can get used to the sound, but typically the EP-10 Plus has too much mid-bass that needs to be EQed out for me to enjoy it. No EQ: Neutral/cold sources are best to me such as an iPod -> Pico Slim, iPhone, or the RoCoo. EQ: EQ in Winamp: -12 dB @ 800 Hz, + 3 dB @ 12K -> HUX-MX1 = great open and spacious sound that allows the treble to come through and show it is very good modded iPod 5.5g -> Pico Slim -12 dB @ 800 Hz = pretty close to the HUD-MX1, allowing the veil to be lifted and the quality of the sound to come out.
[/td] [td=colspan:5] Notes: EQ of -8 dB at 800 Hz in rockbox transforms these from not very listenable to fantastic!Sergio is supposedly working on tuning the EP-10 Plus with less mid-bass, which would make the EP-10 Plus much better and definitely something to consider.
[/td] [td=colspan:5] Keywords: warm, spacious, thick, enhanced bass, forward projection, mid-bass, veiled [/td] [td=colspan:5] Summary: When I wear these I get the impression I am wearing headphones, not IEMs due to the portrayal of space that is almost the size of my LCD-2. The bass from the dynamic woofer is exceptionally deep, textured, with great refinement that has all the power you could want. Unfortunately, in the current form, the EP-10 Plus is too warm and veiled for my taste with all by one of my sources without EQ. When EQed, they start to act more like an expensive custom that has better than custom presentation size. The short sound tube and open back do not give good isolation, the shape and fit are not the standard, and the cable isn't the greatest, however, when EQed the sound is amazing. Sergio did say he could tune each design to the users desire, but it will take time; I am still waiting to hear back from him, and the wait could be an eternity!
[/td] [td=colspan:5] If you like: headphones that have a warm, somewhat dark presentation such as the SM3, HD650, LCD-2 to an extent, IE8, etc. you may like the EP-10 Plus

| Design: Acrylic shell; half sized custom; moderate insertion depth; 2 nozzles per channel; uses filters on each nozzle. The Fabs are based on ReSounds REALsound customs, but Claus has them tuned differently (filters and crossover) along with a more robust cable/shell integration. Cable exit can be over the ear or cable down - I recommend over the ear for microphonics. | Cable: Not detachable, with cable options: 4 pin for phones (iPhone or Nokia) in black or white; coated cable, silver; stranded silver cable (+200 €); provide a cable. I have the iPhone cable which is rubbery. Since I decided to go cable down, there are microphonics (not too bad); I am not sure how much better the other cables will perform in microphonics. | Accessories: Soft carrying bag, replacement filters, manual. 1 year warranty |
| Drivers/configuration: (3,2) dual BA bass driver and single BA mid/treble driver | Build Quality: Very good build quality; cable strain relief seems like it will last. | Isolation: below average - 3/10 (20db @ low frequencies, 25 dB at high frequencies) |
| Sound Signature: Ruler flat across the full spectrum with a natural presentation like being in the 2nd row of a presentation. Balanced in just about every way (warm vs. cold, liquid vs. dry, aggressive vs. laid back, etc.) | Sonic Strengths: Fairly flat frequency response; wide and 3D soundstage; never offensive presentation which might be due to a lack of peaks and combined with the natural presentation. | Sonic Weaknesses: The treble lacks ultimate extension and isn't airy, however it never seems lacking and is never offensive. Soundstage shape is slightly off with the midrange a little closer than the rest of the stage. |
| Listening Volume Performance: Bass weight really starts to come into play when the volume level is medium or higher. These remain clear at louder listening volumes, but seem slightly bass light at very low volumes (compared to my other two bass heavy customs). | ||
| Contact Info: Claus is very responsive and helpful; he is bilingual in German & English. He was very helpful before the transaction and has kept a very high level of customer service after the transaction. | ||

Not overly warm or lean, not overly bright and not dark, with a relaxed yet detailed and never offensive presentation that give you a fantastic 3D presentation from the front of the auditorium perspective. Powered by an iPhone, they really shine and bring whatever is in the song to the table and nothing more. With their wide space they do pretty much every genre right, from classical to classic rock, acoustic to electronics, they present wonderful music!
[/td] [td=colspan:5] If you like: The DBA-02, SA5000, e-Q7, or anything flat but with great deep bass extension the Fabs will be a nice upgrade for you. If you want a neutral and inoffensive presentation, the Fabs are worth a try. [/td] [td=colspan:3] Links: My Full Review; Comparison with ES3

| Design: Acrylic shell (executive option) with dual sound tube design and a flush cable mount (can request recessed) | Cable: Detachable; selected a Westone style compatible plug. Cable is very flexible and a little thinner than the standard Westone cable | Accessories: Impression kit for fitting; Warranty: 90 day fit, 1-year material/hardware warranty |
| Drivers/configuration: (3,2) dual vented BA bass drivers and single upper mid/treble driver | Build Quality: Good shell design, with a few bubbles around one of the jacks. | Isolation: 5/10 26 dB |
| Sound Signature: Warm, full, spacious, and aggressive sound with powerful enhanced bass that extends deep, forward mids, and a prominent treble that has a slight peak. More analytical thank smooth. | Sonic Strengths: Good spaciousness and placement/localization with pop and electronic music; bass is very hard hitting with a very good note decay delivering excellent texture in the price range. | Sonic Weaknesses:Slight edge and ever so slight grain (compared with more expensive customs) to the music in the mids and treble; not very forgiving of poor sources or mastering |

[/td] [td=rowspan:2] Source Matching: The quality of the source is important, and they pair best with a lean/neutral source. They pair very well with the HUD-MX1 with OPA1611 and the modded iPod 5.5g with all 3 of my amps. They don't pair very well with my 801, as the warm source makes for a too warm presentation for my taste.
[/td] [td=rowspan:2] Listening Volume Performance:The X3 performs well from quite listening levels, being a better performer in the bass than the EM3 Pro and Fabs at very low listening volumes. Performance is good throughout the volume range, not changing as the volume increases.
[/td] [td=colspan:5] With Whiplash TWag v2 OM Cable: The TWag cable, while improving the treble slightly, doesn't make much of a difference with the X3. This is more than likely due to the slight grain which overshadows the improvements of the cable.
[/td] [td=colspan:5] Keywords: punchy, dynamic, mid-forward, spacious, enhanced bass [/td] [td=colspan:5] Summary: The Kozee Infinity X3 has a lush, rich spacious, forward presentation that I find very enjoyable for casual listening as well as using while working or working out. The bass hits hard and deep with good texture, speed, and sustained note decay while the mids are presented in a forward way. The treble is emphasized as well as the rest of the spectrum, which fits with the rest of the spectrum rounding out the sound signature. There is a slight grain on some vocal tracks compared with my other customs and an edge to the presentation gets more apparent with lower quality sources. I found the presentation great for pop and electronic music and is great for letting my music inspire me when I am focused on something else such as work or working out. If you like bass heavy presentations and want the benefits that customs provide, the Infinity X3 is worth consideration.
[/td] [td=colspan:5] If you like: enhanced bass, warm universals with forward mids (SM3, Miles Davis, SE535 etc. however the X3 has more treble), listen to any sort of pop today (pop, rock, R&B, rap, etc) or electronic, the X3 may be a good choice for you. Or, if you are a bass head, the X3 may be for you! [/td] [td=colspan:3] Links: Original Kozee thread; My Full Review

| Design: Acrylic shell with triple driver of TF10 configured and tested to have the same frequency response before and after. Also available in silicone, which should work as the drivers do not appear to have vents. | Cable: Detachable; selected a Westone compatible cable; using the stock cable for testing. I went with the Westone cable as I thought that would help bring the mids forward, but the reshell accomplished that with the stock cable, which fits loosely | Accessories: Impression kit for fitting; carrying case |
| Drivers/Configuration: (3,2) dual BA bass drivers; single BA mid/treble driver | Build Quality: Very good build quality, the shells are near flawless. Recessed jack would have been nice, but they are functional as is. | Isolation: 5/10 26 dB |
| Sound Signature: V shaped frequency response. Compared with the universal TF10: the deep bass does not roll off; the mids are slightly more forward (with the stock cable); treble is very close to the universal. | Sonic Strengths: Treble sparkle combined with treble quality not often found in BAs at this price; bass quality and quantity for this price range is good | Sonic Weaknesses: Given the price and sound signature, none. Lacks resolution and impact of more expensive customs resulting in a duller less engaging sound; more pronounced S's than I am used to; soundstage is wide, but not very 3D |
| Listening Volume Performance: The TF10 take a little bit of volume to get the bass going and too much volume results in more chances for sibilance. | ||

[/td] [td=rowspan:2, colspan:2] Source Matching: Clip+: Plenty of bass and treble with the typical recessed TF10 mids; fun sound, although the level of detail is a step down with smoothed treble iPhone 3G: Sounds different than the Clip+, and not necessarily in a good way. First, the treble isn’t as smooth (even though is seems a little smeared on theClip+, that is replaced with roughness). The slightly mid-forward iPhone does help the mids, but the bass seemed a little on the weaker side. Rocoo: Leaner cleaner presentation than the clip+ that has less bass impact and makes the TF10 sound more balanced. 801 (DAC) -> Pico Slim: takes the TF10 to a new level of refinement while opening up the soundstage, expanding it in all directions. Mids don’t seem as recessed vs the Clip+ 801 (DAC): Warmer and less dynamic sounding compared with the 801 -> Pico Slim setup. iPod -> Arrow: while not as spacious as the 801 -> Pico Slim, there is improved clarity in the upper registers, although it isn’t necessarily as smooth or refined. The lower end is a little more boomy.
[/td] [td=colspan:5] With Whiplash TWag v2 OM Cable: Not much difference other than the overall sound is a little crisper and the treble, while still being sharp with S's is slightly better. I was surprised the mids weren't brought forward, but maybe that is because the TF10 has been reshelled.
[/td] [td=colspan:5] Keywords: V shaped, enhanced bass, enhanced treble, wide soundstage [/td] [td=colspan:5] Summary: If you have a TF10, like the sound signature, which is V shaped and want to improve fit/comfort along with possibly improving the deep bass vs. your universal fit (I say possibly because the universal fit is different for everyone) while adding a more ergonomic cable, reshelling will give you what you want.

| Design: Silicone shell with permanent cable and five sound tubes | Cable:black twisted cable with memory wire, available in detachable and non-detachable versions | Accessories/Warranty: carrying case, cleaning tool, cleaning wipes, insertion/removal instructions |
| Drivers/configuration: (5,5) the main woofer, a delayed “ignition” woofer, the low-mids transducer, the high-mids transducer and a super tweeter | Build Quality: Build quality looks very good, however I do want to be very careful when removing the custom, grabbing it by the shell and not the cable. | Isolation: 10/10 - silicone shell isolates better than acrylic and with the long canal of the replacement, the isolation is improved quite a bit |
| Sound Signature: The sound signature is hard to define as the 5-way changes quite a bit with each track from warm to cold, fast to slow, boring to exciting, forward to laid back, etc. In general, the 5-way has a rich, thick, warm, and organic sound that is very detailed, but the detail is presented within the soundstage, not in a bright and very apparent way like most CIEMs. | Sonic Strengths: Exceptional detail levels in the form of clarity of ambient space within the recording allowing micro-details to be recreated that give rooms a better sense of space. The ability to change with each track is better than anything else I have heard, and the dynamic range, especially in the bass region is exceptional. | Sonic Weaknesses: While the 5-way performs admirably with some entry level sources, it needs a high end source to reach its full potential. (Not necessarily a weakness, but the soundstage isn't the largest) |
| Listening Volume Performance: Very good low level bass performance for a balanced armature. | ||

[/td] [td=rowspan:2, colspan:2] Source Matching: The 5-way isn’t a sensitive CIEM, but entry level sources such as the Clip+ can still drive it quite well and show off the advantages over lower cost IEMs. But the 5-way will improve as you move up the quality scale with high end DACs/DAPs, adding to the presentation space and transparency while recreating more micro-detail. Amps can help the sound even more as the 5-way takes well to amping, especially in the bass region where a good amp can show off the bass capability of the 5-way.

On top of that, the 5-way changes its sound signature with each track, bringing out the mastering differences in position, warmth, and other characteristics, making it difficult to pinpoint the sound signature. Tonally the 5-way wouldn’t be considered bright but not lacking treble, however don’t look for clarity through brightness, and while the resolution and detail are present, they aren’t pushed to the front.
The presentation space is large and has a rectangular soundstage shape vs. the traditional oval, with the ability to project both forward and out at the same time quite well. The attack and decay are exceptional which result in a very natural note and the ability to recreate speed and power. Overall, the 5-way is a very neutral and transparent CIEM that performs at an extremely high level and should be a consideration for those that aren’t looking for a bright sound signature.
[/td] [td=colspan:5] If you like: to hear more micro-detail than you more than likely have heard and have music with that information, if you want treble that extends all the way up, if you want great bass with incredible tightness, texture, and accuracy while also having very good note decay, and/or if you want to have better isolation the SE 5-way is an excellent choice. The presentation is similar to the UM3X/SM3 but the frequency response is much flatter. [/td] [td=colspan:3] Links: Spiral Ear 5-way full review; original Spiral Ear thread

| Design: Acrylic shell with vented design for the dynamic driver, dual sound tubes (one per driver), and a detachable cable. | Cable: Detachable, UE compatible pins - cable is stock UE type and not very nice. See cable info below. | Accessories/warranty: Small clamshell case and cleaning tool |
| Drivers/configuration: (2,2) Single dynamic bass driver, single mid/treble driver | Build Quality: Exceptional, stellar build quality that looks amazing including the best writing I have seen. | Isolation: 4/10 Vented, so a little below average. Voices are muted about the same as other acrylic customs but less isolation from engine noise on a plane. |
| Sound Signature: The TS842 has a V shaped sound signature with enhanced bass (although it can sound polite when the song has polite levels), a recessed midrange, and enhanced treble. The upper region sounds reminiscent of the Ety sound, but the bass driver gives the TS842 so much more weight and power they really don't sound similar beyond certain treble notes. Think of the TF10, but technically much better in all regards. | Sonic Strengths:Fantastic bass that can reproduce it all, from natural drums to low piano notes to R&B, trance, and other electronic bass. Treble extension is very good. | Sonic Weaknesses:There are many small peaks in the frequency response, including at 12K which matches with a high sensitivity area in human hearing. The mids are slightly recessed. Mids and treble have a very slight edge to them. |
| Listening Volume Performance: Very good low level bass performance | ||

[/td] [td=rowspan:2, colspan:2] Source Matching: There isn't a huge difference between sources with few exceptions. If you have a Clip+ to drive the TS842, you will probably be very happy. All the steps up produce more enjoyable sound, but not by a large margin. While the 801 is the most detailed of the sources I used to review the TS842, it wasn't my favorite. I liked the sources that smoothed the treble out a little such as the iPod->Arrow and the HUD-MX1 as well as the Clip+, although there was a difference in detail. But, if you are using it for less than ideal conditions, such as in a noisy environment or while focused on something else, it doesn't make a big difference and will likely not be noticed. The TS842 is easy to drive and has thunderous bass from just about any source! More info
[/td] [td=colspan:5] With Athena (V 1.1) and Crystal cables: The Crystal cable ($41.85 shipped) improves the clarity across the spectrum while increasing the speed of the bass attack and slightly cleans up the treble, offering an overall improvement in the sound. The Athena cable ($86.85) was a pleasure to use as the edge, which was accentuated by the treble peaks, was pretty much removed while improving imaging and overall presentation. To me the Athena cable is a great match with the TS842 taking the sound up a notch and making the TS842 more competitive with higher priced custom IEMs. Check here for more information. [/td] [td=colspan:5] Keywords: Textured bass, sub-bass ability, V shaped, analytical, bright, detailed
[/td] [td=colspan:5] Summary: The TS842 has a lot to offer for those that like the TF10, want bass (dynamic, reverberant bass) with the Ety sound in the mids on up, or just want a fun sounding slightly aggressive custom (and a hybrid at that) that won't break the bank. The bass is fantastic as it has the ability to reproduce any type of bass well and sound like the very best dynamic universal IEM if not better while offering good refinement and quality across the rest of the spectrum. If you like a more laid back presentation, want a custom IEM, have around $500 to spend and want exceptional build quality to go along with the great sound quality for the price, the TS842 will be a great purchase. [/td] [td=colspan:5] If you like: Great bass reproduced by dynamic drivers and like the Ety sound in your mids/treble; you like the TF10 but want better bass, a smoother presentation, better detail, wider soundstage and just all around better sound the TS842 is for you! The TS842 does great with all genres, however it is best with electronic (trance, D&B, house, etc.) and pretty good with classical music. [/td] [td=colspan:3] Links: Pictures; My Full Review

| Design: Acrylic shell with 8 drivers in a 4-way configuration with dual sound tubes. Recessed jacks (requested) | Cable: Detachable Westone compatible pins, black twisted cable. The cable is very flexible and ergonomically is great. | Accessories/warranty: Presented in a large white box with an inner black box with fake wood. The accessories include a cleaning tool, soft case, instructions, metal 2 year warranty card, and graph. Carrying case is not great. |
| Drivers/configuration: (8,4) Dual BA bass drivers, dual mid, dual treble, dual high treble | Build Quality: Build quality is very good with a beautiful shell free of bubbles and the recessed jack is very nice. The build quality is among the best I have seen and I have no complaints about fit, finish, or the cable. | Isolation: 5/10 The isolation is on par with my other acrylic shelled customs, which is around 26 dB of isolation. When music is not playing I can hear some external noise, but from a medium-low sound level, it takes a very loud sound to be heard. |
| Sound Signature: The LS8 is similar to a CK10 on steroids, it has a peak at 6K that brings the midrange forward and puts the detail right in your face. The treble is extremely extended and very flat and smooth. The bass is plentiful and has good reverberation and not lacking. The overall presentation provides a full range, smooth, detailed, and enjoyable presentation. | Sonic Strengths: Great clarity across the spectrum with a great balance between lean sound yet still having impressive and tactile bass. Very high resolution of instruments and individual components of the sound. Ultra smooth presentation that is non-fatiguing. Flattest treble response I have experience that extends up to 20KHz. | Sonic Weaknesses: 6K peak slightly changes the tonality of vocals and can add a little sharpness to the S's with some sources (but not all). |
| Listening Volume Performance: Very good at all but extremely low listening volumes. | ||

[/td] [td=rowspan:2, colspan:2] Source Matching: The Clip+ is a great match for ultra portability and going from there, adding a more detailed DAC section in the source chain will result in marginal improvements. Amping with the right amp will further improve the experience. Best source: 801->Stepdance Best desktop: HUD-MX1->Stepdance
Best portable: Clip+
[/td] [td=colspan:5] With Whiplash TWag v2 OM Cable: The TWag cable tightened the bass and increased the dynamics slightly as well as slightly changed the midrange presentation, adding clarity and more front-to-back space. However, with some tracks I found the soundstage size to sound a little odd and other songs the midrange frequency response was a little less impressive than with the stock cable. I am torn here as there are some slight improvements, but other aspects are decreased. The TWag does look better than the stock cable, but ergonomically the stock cable is slightly ahead of the TWag due to the flexibility. With Beat Audio Supreme Rose Cable: The Supreme Rose performed similarly, but to a lesser extent than the TWag but a more intimate presentation. The presentation issues were still there, but to a lesser extent with the Supreme Rose. It also looks better than the stock cable and ergonomically is on par with the stock cable. With Beat Audio Cronus Cable: Summary: This cable comparison was a difficult one because the possible changes are very small. I think that due to the sound signature of the LS8, the cables do slightly improved the strengths of the LS8 with little change, and arguably a positive change overall since they seem to change the midrange presentation slightly. When I used the cables with a less detailed source than my 801->Stepdance combo the differences seemed to disappear.
[/td] [td=colspan:5] Keywords: punchy, dynamic, bright, liquid, detailed, exciting, extended, bass enhanced, speed
[/td] [td=colspan:5] Summary: The LS8 is an amazing sounding custom IEM with an emphasis on the midrange, specifically the upper midrange, but does not lack in the bass or treble departments. Bass is powerful with great impact and reverberation while treble is extended and very flat resulting in a very non-fatiguing sound with ultimate detail and fantastic imaging. Source matching is important as with some songs S’s became slightly sharp in contrast to the exceptional smoothness the LS8 usually exhibits. The box it comes in is impressive, unfortunately the carrying case was a letdown. The two year warranty is nice and the build quality is impeccable. If you like a mid-forward presentation that puts you front row, center bringing incredible detail to you, the LS8 is a great choice. Just pick your source wisely! [/td] [td=colspan:5] If you like: The CK10, DBA-02, or other TWFKs, you will probably like the LS8 with added warmth and bass power. Truly a flagship product that produces amazing sound.

| Design: Silicone shell with permanent cable and dual bore. | Cable: Permanent. Not your typical cable, and the performance isn't quite as good as the twisted cable since it is more rigid and will coil, tangle, and not straighten easily. The plug is a neutrik and it is very tight in many of my players/amps. | Accessories: Hard carrying case, soft carrying zipper pouch, instructions, cleaning tool, lubricant, shirt clip |
| Drivers/Configuration: (3,3) 3-way 3 BA with the musical tuning; they also offer a flat tuning for musicians | Build Quality: Build quality seems very good. The weakest point of any silicone custom is the cable and the Mi-3 is more than likely no exception, however, if you remove it as suggested (by the shell), it should be extremely durable. | Isolation: 8/10 - very good isolation due to silicone shell. |
| Sound Signature:Thick and warmish midrange with a slight mid-forwardness to it, smooth and pleasant treble and bass that can be polite or somewhat punchy without being warm or cold. Detail and texturing is good with an overall refinement and smoothness that is exceptional in the price range. The entire presentation has more forward projection than the norm despite the mid-forwardness and has an average size and spaciousness for a custom IEM with its price range. | Sonic Strengths: Exceptional smoothness of the overall presentation and a great balance across the spectrum (with the right source). Natural thickness in the midrange that doesn't reduce clarity. | Sonic Weaknesses: Bass performance can be weak depending on the source. Not the most dynamic of headphones. |

[/td] [td=rowspan:4, colspan:2]
[/td] [td=rowspan:2] Source Matching: The Mi-3 is source dependent and really benefits from an amp or a source with more power. If you want more bass, an amp like the Arrow with a bass boost or the Stepdance that can control the drivers and enhances the bass standard will be good fits. Depending on your preferences and what you are used to, the Mi-3 will sound find from an iPhone, but using it with a good amp does raise the performance of the Mi-3.
[/td] [td=rowspan:2] Listening Volume Performance : The sensitivity of the Mi-3 is lower than all my other customs in a similar price range and is much more dependent on the source and tracks than any other IEM I own. The low volume performance is dependent on the source and can range from poor to average. The bass driver needs power to get going and DAPs with weaker outputs (Clip+ for example) don't perform as well as an amp.
[/td] [td=colspan:5] Keywords: rich, warm, forward projection, liquid, 3D, bass neutral
[/td] [td=colspan:5] Summary: If you want a comfortable, affordable custom IEM that offers amazing smoothness with better than acrylic isolation, the Mi-3 is an attractive product. Included accessories are top notch and build quality is very good, although the cable has memory and gets tangles easier than the typical twisted cables. Minerva customer service is great and when combined with build quality instills confidence. The Mi-3 presents music with a great smoothness that I have not heard within the price range and can be very enjoyable when using a source that can provide some power. But be prepared to find the right source to get the most out of the Mi-3, and the bass response isn't going to rattle your teeth. Overall the Mi-3 has a lot to offer and will make many owners very satisfied.
[/td] [td=colspan:5] If you like: thicker, smoother presentations the Mi-3 is hard to beat for the price. The Mi-3 does well with acoustic music such as guitar, symphony, vocals, jazz, and most rock for example, but can still work with other genres, even metal. [/td] [td=colspan:3] Links: My full review

| Design: Acrylic shell with detachable cable and 2 sound tubes. Sound tubes have replaceable wax filters. Shell is filled with silicone for increased isolation and damage resistance. | Cable: Detachable, silver twisted with 90 degree 3.5mm plug | Accessories/Warranty:Large carrying case containing: the custom IEM in a smaller semi-hard carrying case; smaller leather carrying case; printed instructions and information; IPA wipes; 3.5mm to 1/4" adapter, cleaning tools, filter replacement set (8 replacement filters); 2 year warranty with a 30 day refit |
| Drivers/Configuration: (4,3) 4 balanced armature drivers, 3-way system, 2nd order (12dB/octave) hard-wired passive crossover (50 Hz and 5,3 kHz); dual bass drivers; two switches: one turns on/off the 2nd bass unit and the other adds "presence" | Build Quality: Outside shell has excellent build quality, inside is filled with silicone for durability/increased isolation and has bubbles throughout. | Isolation: 8/10 - silicone filled shell isolates better than hollow shells and as good as the full silicone shelled custom IEMs I have. |
| Sound Signature: Adjustable bass and "presence," which is a bump in the midrange! Spacious presentation. There are really 4 different sound signatures: Laid back and spacious with enhanced bass; laid back and spacious with more balanced bass; mid forward with enhanced bass; mid-forward with balanced bass. With the bass switch on the deep bass becomes very punchy and powerful. | Sonic Strengths: Amazing spaciousness/presentation that makes recordings come alive and sound extremely realistic. Exceptional transparency. Four separate sound signatures. Deep bass power and sub-bass rumble is top notch. | Sonic Weaknesses: Treble doesn't extend as high as the LS8 or SE 5-way. Requires a better than entry level DAP to really sound great. |
| Listening Volume Performance: Not the most sensitive custom IEM, the low volume performance is among the best of the BA IEMs I have heard as the bass kicks in at low volumes. The lower sensitivity makes it difficult for many DAPs to drive, which might also be in part due to the more complex crossover/switching features. | ||

[/td] [td=rowspan:2, colspan:2] Source Matching: Quality of the source is very important with the SA-43 in order to achieve the potential of the SA-4. If you are only going to use low end DAPs or your phone, you might as well look elsewhere, not that the SA-43 is bad per se, but the playing field was leveled. Basically, the SA-43 scales well and can perform at a very high level when fed from a high level source.

[/td] [td=colspan:5] Keywords: very spacious, 3D, realistic, ambiance, enhanced bass, neutral treble, natural tone [/td] [td=colspan:5] Summary: The SA-43 is special in the way it recreates the space of a presentation along with stellar transparency, putting everything together to make not just music but an experience. Isolation is also top notch as the silicone filled acrylic shell isolates slightly better than my two pure silicone custom IEMs. Not only that, you can customize the frequency response to your liking with a switch that controls the extra bass driver and a switch to add midrange "presence." Spatial presentation is top notch in size, proportions, instrument placement, and timbre. Add great dynamics, speed, tone, and pace and all genres of music sound captivating and involving. Detail levels, are right around the middle of the pack; there are some that do better and some that do worse. It is very important to note that the SA-43 requires a good source or you will lose the great space and some dynamics resulting in a more average performance. The included accessory pack is extensive however I am not very fond of the carrying case Overall the SA-43 is an incredible custom IEM!
[/td] [td=colspan:5] If you like: When used with a good source the SA-43 is great for those that want great spaciousness and transparency.

| Sound Signature: Fairly balanced sound with decent bass weight and reverb with a slightly analytical yet refined sound. Space is average. | Sonic Strengths: The synergistic presentation that is on the slightly bright and analytical side but has more note thickness and warmth with a great cohesive presentation from bass through treble. | Sonic Weaknesses: Detail levels aren't all that impressive; bass and treble are not fully extended |

[/td] [td=rowspan:2] Listening Volume Performance: Very good performance at low volumes, the bass is at full power without much power, resulting in the sound not changing much at different volume levels.
[/td] [td=colspan:5] keywords: tapering up frequency response (emphasis increases as the frequency response increases), extended, liquid, warm, bass neutral [/td] [td=colspan:5] Summary: One of the few small form factor custom IEMs on the market, the SA-12 has a lot to offer including a sound I wasn't expecting from the TWFK driver. The accessory pack is thorough although not perfect, but better than average. Build quality is great and isolation isn't bad for a canal only custom IEM. On the sound front the SA-12 has an overall lean toward an analytical and bright presentation but the thickness of the note and warmth give the SA-12 a richness not usually found with the other characteristics, not to mention acceptable bass rumble. The SA-12 can't quite keep up with the detail or extension of the competition in the price range, but I can see many people enjoying the overall combo of the rich yet analytical and close to neutral presentation.
[/td] [td=colspan:5] If you like: A presentation that is between relaxed and analytical with warmth, this sound will be very pleasing. Recommended for many genres but not for genres where soundstage should be large such as classical, but the bass reverb is great for pop and electronic music.

| Design: Acrylic shell with detachable cable and 3 sound tubes | Cable: Detachable | Accessories: Hard case, soft drawstring bag, cleaning tool |
| Drivers/Configuration: (8,3) Quad BA bass drivers, dual BA mid drivers, dual BA treble drivers | Build Quality: The shell is free from defects and has overall good build quality. | Isolation: 5/10 Isolation is average for an acrylic shelled custom. |
| Sound Signature: Enhanced bass from about 100 Hz down results in a punchy presentation that is generally different than other custom IEMs enhanced bass. Midrange is very neurtal and treble is on the brighter side. High levels of detail with good clarity but a somewhat analytical sound due to a somewhat quick note decay. The presentation is spacious, but not very 3D. | Sonic Strengths: Bass that has more speed, texture, and detail than anything else I have heard, while providing the ability to rumble near dynamic driver levels. | Sonic Weaknesses: The overall presentation space, while wide, is somewhat compressed front-to-back and top-to-bottom in comparison with other above $1K custom IEMs. |

[/td] [td=rowspan:2] Source Matching: The JH16 doesn’t need much power to be driven well and headphone outputs from some DAPs sound quite good with the JH16, even if missing some of the micro-detail in the instruments. Due to the very high sensitivity of the JH16, sources with an analog volume control such as the 801 and HUD-MX1 had some issues at my normal low to very low listening volumes due to a channel imbalance which went away at moderate volume levels.
[/td] [td=rowspan:2] Listening Volume Performance:
[/td] [td=colspan:5] With Whiplash TWag v2 OM Cable: The Whiplash TWag cable fixes the soundstage depth issue with the JH16 while smoothing the presentation, resulting in an overall improvement.
[/td] [td=colspan:5] Keywords: punchy, dynamic, analytical, bright, bass enhanced, detailed, very spacious, speed, sub-bass ability [/td] [td=colspan:5] Summary: The JH16 gives new meaning to bass with a performance that combines enhancement with dynamics, detail, punch, speed, and rumble. Instrument detail is plentiful across the spectrum with an added liquidity to the vocal range and an enhancement in the upper mids/lower treble that accentuates the clarity. Soundstage width is great and competes with/bests similarly priced custom IEMs I have heard. However the depth and height of the performance does fall short of the others, sounding compressed in comparison with tracks that are presented with a large 3D space. Music is presented in more of an analytical sort of way, so if you are looking for a thicker and more relaxed presentation, look elsewhere. Driving the JH16 is easy as a Clip+ does quite a good job and moving up the source chain doesn’t necessarily result in better overall sound except for a little more detail and possibly a larger soundstage with some music. Accessories are fine for this price point and when you use the dual case setup the JH16 will be well protected.
The JH16 is great with today’s pop, hip hop, and a wide range of electronic music where it brings out the most of many over-saturated songs adding punch, detail, space, and excitement while acoustic music with a 3D presentation may disappoint due to the soundstage presentation not having the best depth/height. For the initial target market, on stage monitoring, the JH16 does perform quite well as it pulls out the details for you to hear and if you are a singer it presents vocals with added liquidity. The ability to customize the shell with artwork is nice and I get compliments on the look of mine. If you get the JH16 be prepared for enhanced bass regardless of what you are listening to, from rap to country, even if you don’t want the enhancement.
[/td] [td=colspan:5] If you like: The JH16 is perfect for electronics and pop music! Stage performers that want to hear every detail. Enhanced bass with a neutral midrange presentation and a bright, airy treble to go with a fast and slightly anaytical sound, the JH16 fits the bill.

| Design: Acrylic shell with detachable cable and triple sound tubes. Recessed sound tubes prevent wax from entering the sound tubes | Cable: Detachable. The cable is the standard silver custom IEM cable. | Accessories: Hard case, soft drawstring bag, cleaning tool |
| Drivers/Configuration: (5,4) - single sub-bass driver, dual bass driver, TWFK midrange/treble driver with internal crossover | Build Quality: Build quality is good, on par with many of the custom IEMs in the price range. There are some minor bubbles in the shell, but they are difficult to see unless you are looking for them. The sound tubes are recessed and finished well. | Isolation: 6/10 Isolation is slightly better than a typical custom IEM, but not by all that much. This is most likely due to the silicone fill of the canal. |
| Sound Signature: The 5X is a well balanced custom IEM with a slightly mid-forward presentation, enhanced bass, and a slightly elevated from neutral (to my ears) treble. Source and mastering comes through due to the transparency and the bass can be huge to none depending on what is in your music. There is a warmth and richness to the presentation that is very pleasing while not being too thick, and a sense of power and efforlessness. | Sonic Strengths: Great transparency;very 3D soundstage; powerful bass; extension on both ends of the spectrum for the price | Sonic Weaknesses: Midrange not as tonally accurate as some higher cost custom IEMs; treble detail is less than more expensive custom IEMs |

[/td] [td=rowspan:2] Source Matching: The 5X is easy to drive and as long as you are using a good amp and DAC it doesn't make a huge difference which one you actually use. When you do move up to a nice DAP/DAC/amp from something like the Clip+ or iPhone you will be rewarded with a greatly improved soundstage that is very 3D and immersive.
[/td] [td=rowspan:2] Listening Volume Performance: The 5X has adequate bass performance at very low volumes and performs within the top group of BA custom IEMs for low volume bass performance. Once the volume is at a low-moderate level the bass kicks up a notch. At louder volumes the overall sound is still very listenable and the treble non-offensive. The 5X has better than typical performance for the price range. Sensitivity is on the higher side, but not to the level of the JH16 or LS8. This helps with many sources with analog volume control issues or hiss problems.
[/td] [td=colspan:5] Keywords: liquid, transparent, enhanced bass, balanced, powerful, effortless, rich, extended frequency response, sub-bass ability [/td] [td=colspan:5] Summary: Breaking the current driver/price performance barriers the aud-5X is a very capable performer. Technically the 5X punches well above its price point, closing in on more expensive custom IEMs at double the prices. The strengths include transparency, bass capability, dynamics, soundstage proportions, and bass and midrange resolution. The overall sound is refined, liquid, a little on the warm and rich side with some bass enhancement and a brighter treble to go along with a bit of a mid-forward presentation. The coherence across the frequency spectrum is excellent with similar note thickness from top to bottom and excellent integration from the lowest notes to the highest. When compared with others in the price point, the aud-5X really doesn't have technical weaknesses. Being the aud stands for audiophile, the presentation has hit a sweet spot in the sound with the overall balance.

| Design: Acrylic shell with detachable cable and dual sound tubes. Unique cable design. | Cable: Detachable. The cable is black and has 4 wires tightly braided below the Y-split and has a very tight twist above the Y-split. The shell connector is unique. | Accessories: The accessory kit is standard, coming with a case, cleaning tool, and 1/4” to 1/8” adapter for use with pro equipment, or many desktop amps. The case is top notch from a look, feel, and function perspective. |
| Drivers/Configuration: (3,3) Triple driver with dual sound tubes | Build Quality: Excellent build quality with the best shell connector I have seen, which is protruding. The shell is perfect with no bubbles or imperfections and the cable is top notch and the included case is very strong and usable. The UERM should stand up to abuse and last for a very long time. | Isolation: 6/10 - the UERM seems to provide a little more isolation than the typical acrylic shelled custom IEM. |
| Sound Signature: Sound designed as a reference. The sound is on the brighter sound with an analytical nature, but not lacking in any way. Mids are slightly forward and the treble is a little more forward still. Music is presented in a very 3D way and detail levels are good to go along with a high level of clarity. | Sonic Strengths: Soundstage proportions are excellent with very good size resulting in a very realistic recreation of music. Very good clarity. | Sonic Weaknesses: The treble can be harsh with poorly mastered tracks which are more numerous than expected and not harsh with my other similarly priced custom IEMs. |

[/td] [td=rowspan:2] Source Matching: The UERM is easy to drive, therefore an amp does little to help the sound. DAC quality and flavor will matter as the UERM is fairly transparent to the source and does scale somewhat with the source.
[/td] [td=rowspan:2] Listening Volume Performance: The UERM is a good low volume performer and has no issues with loud volumes.
[/td] [td=colspan:5] My usage: analytical, accurate, bright, neutral bass, detailed, transpaent [/td] [td=colspan:5] Summary: The UERM is what it set out to be, a reference monitor, and an excellent one at that. While not perfect when compared with similarly priced competition, it does offer a good mix of attributes that when combined result in an overall good presentation that recording engineers can use for exceptional masters. As for the audiophile audience, the UERM is a good choice for those looking for transparency and accuracy more so than a musical experience, although I can thoroughly enjoy music with the UERM. The accessories are very nice, including the metal case which fits the UERM perfectly and offers great functionality with ease of use and a good look. The cable is better than other stock cables I have seen and the shell connector is protruding instead of flush or recessed resulting in a very solid and durable design.
The UERM does present high levels of detail within excellent soundstage recreation both in the size and shape of the space, being among the best I have heard in this regard. The overall sound is bright resulting in very good clarity, with a gently increasing emphasis on the frequency spectrum as the frequency increases, bringing the treble more forward than the mids by a bit, and the mids more forward than the bass by a bit. The drivers are well matched and sound very cohesive and the single bass driver does a fairly good job pumping out bass. While the UERM is very good for the presentation it has, the sound is an analytical one which lends to the ability to hear very good instrument detail but the ambiance of a presentation isn’t recreated they way it is with many competitors. The biggest issue I had with the UERM is that the treble can be harsh depending on the recording, and while this isn't unique to the UERM, it did occur with more songs than any other custom IEM in the price range. And dynamics, while overall good, are not quite up to the level of other $1000+ custom IEMs I have heard.
All in all the UERM has a place among the other custom IEMs I have heard in the price range as it offers a reference sound with an exceptional presentation; a combo I have not heard up to this point in a custom IEM. Combine that with the accessories and cable and the UERM stands up well with the competition.
[/td] [td=colspan:5] If you like: The TWFK dual drivers but want way more out of your sound, the UERM will give you that. The UERM does live up to the bill and would be great for studio engineers as well as audiophiles that want an analytical sound without giving up much. [/td] [td=colspan:3] Links: Full review here

| Design: Acrylic shell with detachable cable and a single sound tube. There are some electronics with FST technology in the cable. The shell has a vent hold in the middle of the back of the shell and there is a sound tube connecting the rear chamber and the front of the driver with a filter between the two. | Cable: Detachable. The cable uses the typical Beat Audio style ear guides and the initial look and feel reminds me of a lower quality Cronus. The metal can located about 4.5" (114.3mm) from the straight 3.5mm plug measures 1.68" (42.68mm) long by 0.4" (10.39mm) and has strain relief on both sides. This makes the replacement cables limited if you want the FST electronics. The right shell connector is black and the left is silver. After extended use the cable did become tangle prone, at least much more so than other stock cables. | Accessories: The i9pro comes with a Dolfin box case that has an inner lining and a cleaning tool. There is not much more that would be needed to be included, so the accessories are fine as the dolphin box is as good as an Otter box. |
| Drivers/Configuration: (1,1) Single 14mm dynamic driver, vented. | Build Quality: Overall the shell build quality is great and there are no visible bubbles or imperfections in the shell with a nice finish. The cable sockets are flush and the pins aren’t quite as tight as they should be in my opinion. The cable does come loose with use and I even had a shell separate during A/Bing. This can be fixed by slightly clamping the pins with pliers. Also, over time the cable that for the left shell connector was able to spin around and often the cable was not at the correct angle when I started to insert the i9pro. | Isolation: Being that the i9pro is vented it doesn’t provide quite as good of isolation as the typical sealed shell custom IEM. Without music playing the isolation is similar to an open backed IEM such as the FX700. When music is playing the sound masks the leakage but the amount of leakage seems to be reduced in comparison with normal open backed IEMs, but is still not quite on par with the full shelled closed custom IEMs. |
| Sound Signature: Warm and spacious presentation that has enhanced bass and a nice balance across the midrange through the treble, which is rolled off. Great coherence across the frequency spectrum and a very enjoyable presentation with a rich and natural presentation | Sonic Strengths: Spaciousness due to the FST can be better than anything else, but also can at times be a weakness; liquid presentation; conveyance of power. | Sonic Weaknesses: FST enhances the bass and results in some lack of control in the bass; treble roll off at 13KHz. |

[/td] [td=rowspan:2] Source Matching: The i9pro has the ability to resolve more detail than the entry level DAPs such as the Clip+ and iPod, and even the RoCoo and Studio V can output, so using an 801 or decent DAC will reap some benefits. Amps also help, but to do the FST, only to a point. If an amp strengthens the bass too much the FST will cause the bass to be less controlled affecting the sound in a negative way as happened with the Anedio D1. The 801 is overall a very good match, but due to the price something such as an iPod/iPhone to the uHA-120 via LOD will be a great compromise between price and performance.
[/td] [td=rowspan:2] Listening Volume Performance: The i9pro is good at low volumes but the bass levels are lower, probably due to perception from human loudness curves. Due to the sensitivity there more than likely won't be many issues with sources that have analog volume controls. The biggest issue I have with the i9pro as far as volume is at louder volumes. For whatever reason, the driver becomes uncontrolled and when there is a lot of bass it bleeds to the midrange. This isn't an issue for me as I don't listen at volumes that will cause the issue (and I highly recommend you don't listen that loud also), but it is there if you crank the volume.
[/td] [td=colspan:5] Key words: Warm, rich, liquid, enhanced spaciousness, enhanced bass, 3D, sub-bass ability [/td] [td=colspan:5] Summary: FST technology gives the i9pro a pretty unique sound in its price range with added spaciousness to go with the sound of a dynamic driver. The spaciousness comes with enhanced bass, an overall warm presentation and a great treble quality. The level of enhancement is high with punchy and deep, rumbling bass. Detail levels are good for the price range and presented in a liquid and enjoyable way. Note decay sounds very natural but speed is average. Piano sounds amazing, D&B bombastic, and most genres sound right. Midrange tonality is on the warmer side.
But, with the good comes some issues including treble roll off at 13K which can affect air and not recreate some of the harmonics and spatial queues that give ambiance to the upper end. FST increases the bass and this can lead to the bass sounding a little uncontrolled at times, and the added spatial qualities can affect instrument placement for very spacious tracks. However, even with these issue the overall presentation of the i9pro is very enjoyable and without direct comparison you will most likely be hard pressed to hear the issues. So go ahead, rattle your brain with 14mm of dynamic driver that give you a nice spatial experience.

[/td] [td=colspan:5] Keywords: neutral bass; transparent; 3D; natural, spacious, tonally accurate [/td] [td=colspan:5] Summary: Clarity, imaging, dynamics, and full range reproduction highlight the biggest strengths of the NT-6, however there are still other exceptional traits of this reference beast. The NT-6 isn't shy about pointing out flaws in other CIEMs when compared directly and doesn't exhibit much itself, which is indicative of the very high technical performance. The biggest weakness of the NT-6 is that the depth of the presentation isn't up to par with a few others in the price range, but the differences aren't too large. Bass is neutral but not lacking with the ability to recreate sub-bass rumble and pump out a solid bass performance.
Accessories are decent but not without issue. The case is very attractive but a bit small and I often had issues closing it and the NT-6 has a non-standard cable, which is microphonic so additional purchases of replacement items may be a necessity from the start. However, taking into account the sound, the NT-6 is still an exceptional value due to the high level of sound quality and build quality. If you are looking for a reference monitor and sound really matters, you have to consider the NT-6.

[/td] [td=rowspan:2] Source Matching: The EM4 performs very well from entry level DAPs such as the Clip+ and there are minimal improvements as you move up the listening chain. Higher end DACs will add some additional space and detail to presentations while an amp will control the bass a bit better, but overall the gains aren't huge. There is no need to go all out with the source unless you really want to eke out every last bit of performance.
[/td] [td=rowspan:2] Listening Volume Performance: The EM4 has very good volume performance from the low end through what I consider loud. The bass drivers kick in at a relatively low level, but a bit of power is needed to really achieve what the EM4 can do in the bass region. The sound signature doesn't change from that point on up to very loud.
[/td] [td=colspan:5] Key words: warm, right, clear, bright, bass power, bass rumble, amazing vocals, imaging, airy [/td] [td=colspan:5] Summary: Tuned for the audiophile, the EM4 gives an impressive presentation, immersing you in the experience and bringing the performance right to you. The mid-forward presentation puts vocals up close and personal while giving you great tonal quality and imaging with bass that is enhanced, powerful, and visceral and treble is extended and realistic. Everything is presented in a very fluid way and thin is never a word that comes to mind with the EM4, but that doesn't prevent a bright and very clear presentation. Detail levels are very good, especially in the midrange, and with great transparency, the EM4 gets out of the way of your music.
The liquidity allows the EM4 to be very forgiving, but the side effect is a slight lowering of treble detail, and bass texturing is typically a bit lower than the competition, which is a tradeoff for the enhancement and capability. In direct comparison with many others high end CIEMs, the EM4 has a bit of a dip in the upper midrange which can lead to the sound being slightly 'off' sounding at times. However, dynamics and speed are excellent leading to a presentation that is exciting, punchy and fast while being warm and immersive; an impressive combination. The EM4 has a special sound that reminds me of the SM3 when I first heard it, but oh so much better in every way!
Overall, the EM4 gives a combination of speed and clarity with warmth and richness I have not heard elsewhere.
[/td] [td=colspan:5] If you like: The SM3 but want a brighter presentation or like the SE535 but want a more coherent presentation, the EM4 will deliver. Even if you don't like either but want a mid-forward presentation the EM4 does it in a way that is immersive and engaging with plenty of bass and an extremely high technical level of performance.

[/td] [td=rowspan:2] Source Matching: The Reference is not too difficult to drive and lower end sources realize nearly all the detail and space available, but improving the amp section does result in a tighter, better controlled sound. Adding an amp to your existing source such as an iPhone or Fuze will result in as good of an experience, if not better than upgrading to an expensive DAC.
[/td] [td=rowspan:2] Listening Volume Performance: The Reference has decent low volume performance, but at very low volumes the bass driver doesn’t really kick resulting in a flatter presentation. At moderate and above volume the Reference offers the full power and glory of the presentation, not having any issues at the loudest level I want to listen at for even a short period of time.
[/td] [td=colspan:5] Key words: Neutral, natural, 3D, spacious, musical, extended, warm [/td] [td=colspan:5] Summary: The Alclair Reference provides a balanced yet musical presentation that offers an impressively flat presentation with class leading clarity at a relatively affordable price of $499. Bass rumble is good for a balanced armature driver with extension down to 20 Hz, providing good texturing and control. The midrange is neither forward nor laid back with good spatial recreation; however the cohesion of the presentation is a bit below standard due to less definition in the center of the soundstage. Note thickness sounds very natural with very good attack and decay, especially in the treble region, standing out amongst its peers for the natural presentation.
The Reference can be used as just that, a reference as it has the flattest, most neutral sound that I have heard in the price range. It is, however, not quite as bright as the other ‘reference’ CIEMs, which do cost double+ and are and revealing of poor masters. Audio enthusiasts and audiophiles that are looking for a balanced, neutral sound with good capabilities that won’t break the bank should take a look at the Reference as Alclair has done an excellent job of combining musicality with reference sound, making the Reference very versatile and enjoyable.

| Design: Full silicone shell with dual sound tubes and proprietary detachable cable. The Live! version has microphones for the | Cable: Proprietary cable connector that is "serviceable." Kevlar construction that is different than standard cables. No microphonics. Initially the cable was prone to tangling, but over time the cable performance improved dramatically, becoming a very nice cable all around. | Accessories: The T1 Live! comes with a Pelican case, leather zipper carry pouch, cleaning tool, comfort cream, care and instruction booklet, and a 3.5mm to 1/4" inch step-up stereo plug. However, from this point forward, ACS will be supplying a new case that can be seen here instead of the Pelican case. |
| Drivers/Configuration: Three-way three driver design. | Build Quality: Excellent. | Isolation: Using a silicone shell, the T1 Live! provides better isolation than a typical acrylic shell, which is rated at 27 dB. The isolation is similar to the Spiral Ear and a bit above the denser Minerva shells, which also have a different shape to them, only slightly trailing the Starkey SA-43. |
| Sound Signature: Mid and bass forward with a warm and musical presentation with a small upper midrange boost that results in nice clarity. The treble isn't lacking, but is relaxed and a bit laid back in comparison with the rest of the spectrum. Good detail levels and an engaging, enveloping 3D presentation. While I don't think of "detailed" when I think of the T1 Live!, it does have very good detail levels. Very organic/natural sounding. | Sonic Strengths: Extremely natural, rich, and organic, especially in the vocal region. Can make some other CIEMs in its class sound tonally off at times. | Sonic Weaknesses: Midrange can become congested with complex music in comparison with other high end custom IEMs, especially with lower end sources. |

[/td] [td=rowspan:2] Source Matching: While the T1 Live! does OK with DAPs, noticeable sound improvements will be realized from amps and higher resolution DACs. The T1 Live! was designed for stage use with wireless packs, which I don’t currently have for testing.
[/td] [td=rowspan:2] Listening Volume Performance: The T1 Live! performance at very low volumes isn’t the greatest as the bass driver doesn’t fully kick in until low volumes, and is up to full speed at mid-low volumes. At louder volumes the T1 Live! can sound more congested than at lower volumes with complex tracks.
[/td]
But it is not all perfect, as nothing is. The T1 Live! can sound a bit congested with complex music at louder volumes when compared with others in its class, and bass rumble is bested by the multi-bass balanced armature driver and dynamic driver custom IEMs. This is worse with lower end DAPs and improves with amps, although the T1 Live! was designed to be used with a wireless pack, which I do have for source matching. But the more natural sounding tone makes up for these shortcomings vs. much of the competition. Overall, performance is very competitive for the price, and combined with the rich and involving recreation of music, the T1 Live! is a great option stage and for the audio enthusiast.
[/td] [td=colspan:5] If you like: Tube sound that is neutral and not lacking, the T1 Live! is a great choice. [/td] [td=colspan:3] Links: My full review

| Design: Acrylic shell with a detachable cable and a single large bore | Cable: Non-standard cable as it is covered in heat shrink | Accessories: Metal DUNU case, cleaning cloth, and cleaning tool |
| Drivers/Configuration: 4 balanced armatures in a 4-way configuration with compound upper drivers and single drivers for the lows. Single, large sound bore with three sound tubes feeding it. | Build Quality: Shell has excellent build quality, reminding me of excellent Thousand Sounds shell | Isolation: Average for an acrylic shelled custom IEM. |
| Sound Signature: Mid-forward presentation with good imaging and a 3D presentation. Bass is slightly enhanced with a somewhat bright sound that is all in good balance and tied together coherently. While not lush and warm, the DC4 isn't overly analytical either, making for an enjoyable experience. | Sonic Strengths: Presentation depth and imaging making for a very involving presentation with vocals and other mid-forward recordings. Very good bass response. | Sonic Weaknesses: Poor source combinations and warmer tracks can make the DC4 sound thick and slightly congested at times compared with other CIEMs in the price range. |

[/td] [td=rowspan:2] Source Matching: The DC4 is selective about the sources that it sounds best with, which are those that are of the mid-forward type with good depth to the presentation. While more expensive sources sound better than the entry level DAPs, more expensive sources didn’t necessarily sound better than mid-priced ones since presentation matching is very important. Also, the DC4 is very sensitive and can bring out the hiss/noise in your sources more so than just about any custom IEM I have heard.
[/td] [td=rowspan:2] Listening Volume Performance: The DC4 performs well at low volumes, especially when there is a powerful source. The bass driver kicks in and is dynamic at a moderately low volume. After turning the volume up past what I consider loud listening, although many may not, the DC4 starts to become rougher and congested sounding. Again, this is at listening levels that really aren’t necessary since the DC4 isolates well, and you will damage your hearing if you listen at those volumes for any extended period of time.
[/td] [td=colspan:5] Key words: Mid-forward, l iquid, warm, rich, powerful, coherent, transparent, balanced, forgiving, 3D, imaging, presentation depth [/td] [td=colspan:5] Summary: DUNU’s first custom IEM, the DC4, is a winner in many ways providing an extremely involving and enjoyable presentation that is mid-forward, liquid, and rich. Transparency and coherence are top notch within the price range and close to CIEMs that cost double, and when paired with a synergistic source, the depth of the presentation is impressive. With a frequency response that is fairly balanced but not necessarily neutral, the DC4 is fun and quite capable in the bass response. Certain characteristics change depending on the tracks and sources, improving or reducing the listening experience, however the DC4 is quite forgiving of poorly mastered tracks.
Overall, the DC4 has a great sound signature with enhanced, capable and warm bass, a liquid midrange that is presented up-close and personal, and treble that has a nice balance between bright and dark, all leading to a very engrossing and non-fatiguing experience. The DC4 is a good starter custom IEM as it has a very enjoyable sound, it can grow with you as you upgrade your sources, and will be forgiving as you improve the quality of your music collection.
[/td] [td=colspan:5] If you like: The SM3 or mid-forward, enveloping vocals with plenty of technical capability, the DC4 will fit the bill. [/td] [td=colspan:3] Links: My Full Review

[/td] [td=rowspan:2] Source Matching: The AS-1b can be driven from sources such as the iPhone or Clip+, but the higher quality the source, the better the AS-1b will sound. I recommend getting a decent amp for maximum enjoyment of the AS-1b.
[/td] [td=rowspan:2] Listening Volume Performance: Playing loud is not a problem for the AS-1b as the 15mm driver has plenty of headroom, and moderate volumes are fine as well, but due in large part to the sound signature, low to very low volume listening results in the perception of lower amounts of bass and treble due to human loudness curves.
[/td] [td=colspan:5] Key words: Mid-forward, l iquid, warm, rich, powerful, thick, 3D, imaging, presentation depth [/td] [td=colspan:5] Summary: The AS-1b is a very capable performer that was designed for musicians, and many of the musicians I know like to EQ their equipment, which the AS-1b reacts very well to. The 15mm driver has great dynamics and can play at very loud levels if need be. The overall mid-focused sound signature has great presentation depth and nice imaging, instrument placement, and separation making for an involving presentation. Don't expect a bright sound from the AS-1b. The magic of the AS-1b is in the recreation of space, which it does extremely well.
[/td] [td=colspan:5] If you like: The SM3 or mid-forward, enveloping vocals with plenty of bass ability. If you want to EQ the sound, the AS-1b reacts very well to EQing. [/td] [td=colspan:3] Links:

| Design: Acrylic shell with 3 sound tubes and a detachable cable. | Cable: Detachable, coated cable reminiscent of the MEElectronics M6 clear cable, but thicker. | Accessories: The AM4 comes with a Dolphin case, cloth pouch, cleaning tool, and desiccant, however my AM4 pro only came with a cloth pouch, so I have used the accessory images from the Ambient Acoustics site. |
| Drivers/Configuration: Dual vented bass drivers, single midrange driver, single treble driver. | Build Quality: Excellent fit and finish with solid construction. | Isolation: Average for an acrylic shelled custom IEM. |
| Sound Signature: Open and airy with a nice balance across the spectrum that is on the brighter side, but not necessarily bright while the lower end is neutral yet capable. Detailed and coherent with exceptional depth to the presentation. | Sonic Strengths:The depth of the presentation is exceptional, great dynamics and bass capability, and an extremely natural tone | Sonic Weaknesses: At medium and higher volumes the technical performance decreases, and with lower end sources the upper end can get a bit harsh |

[/td] [td=rowspan:2] Source Matching: The AM4 pro is very scalable: feed it from a better source chain and you will get better results. The difference between the highest and lowest performing sources is quite large and the AM4 pro is selective about the amps/sources it pairs well with.
[/td] [td=rowspan:2] Listening Volume Performance: Performance is excellent at low to medium volumes, but above medium volumes the soundstage becomes less clear and the treble becomes sharper.
[/td] [td=colspan:5] Key words: [/td] [td=colspan:5] Summary: The Ambient Acoustics AM4 pro is an exceptional performer at the price point with a relatively neutral and very natural sound that works for the stage, studio, or just enjoying music. Note decay is very realistic, the soundstage is very 3D with exceptional depth, and dynamic range is impressive, all resulting in a presentation that immersive and engaging while staying neutral but still musical. When supplied by a high quality amp, the AM4 pro can compete with CIEMs that cost double as it scales very well. However, with lower end sources and at louder volumes the clarity can suffer as complex material becomes slightly congested. Overall the AM4 pro performs admirably and will surely develop a following due to the sound quality and value.
[/td] [td=colspan:5] If you like: Balanced sound that isn't lacking in the treble region, but not necessarily bright with plenty of bass capability in a very musical and non-analytical way, the AM4 pro is great. If you have higher end sources to pair with it, the it will perform at well above it's price. [/td] [td=colspan:3] Links: My full review

| Design: Acrylic shell with 3 sound tubes and a detachable cable. | Cable: Detachable, black cable that is unique to Hidition. | Accessories: The NT-6 pro includes a unique metal carrying case that is compact, a cleaning tool, a soft wipe cloth, instructions, and a frequency response chart in a nice box. The case, while larger than the original, still isn’t the biggest so care needs to be taken to close the case all the way since my shells are rather large. |
| Drivers/Configuration: 6 drivers in a 5-way configuration. | Build Quality: Excellent fit and finish with solid construction. | Isolation: Average for an acrylic shelled custom IEM. |
| Sound Signature: Very bright but slightly warm with plenty of bass capability when a song calls for it. The NT-6 pro takes the analytical sound and adds fun and excitement while retaining ultimate detail retrieval. | Sonic Strengths: The highest levels of clarity I have heard; exceptional soundstage presentation that is large and 3D with exceptional imaging and focus | Sonic Weaknesses: While the brightness gives stunning clarity, it can lead to an unnaturally bright tone with some tracks. |

[/td] [td=rowspan:2] Source Matching: The NT-6 pro changes quite a bit with different sources, so finding the right sound for you can take some trial and error. The quality of the DAC section does help with detail and resolution, but especially in achieving the presentation depth and width the NT-6 pro is capable of. For some reason the latest software for the 801 is a horrible match; however, all other DAPs/DACs I have tried don’t have the same issues. Using a good amp also helps where it comes to spatial presentation; however, the small changes to the upper midrange and treble did lead to significant tonal changes. Select your source carefully and be prepared for some trial and error.
[/td] [td=rowspan:2] Listening Volume Performance: Performance at all volume levels is quite good as the enhanced bass helps get the bass driver moving with very low volume levels and the sound signature is retained as much as it can be, taking loudness curves into account. At louder volumes, very heavy bass tracks can get a bit distorted, but I can’t listen for longer than a second of so, and can’t imagine people would have hearing in a year listening at those volumes. Even at loud volumes, there is absolutely no congestion.
[/td] [td=colspan:5] Key words: [/td] [td=colspan:5] Summary: Boasting 6 balanced armatures in a 5-way design, the NT-6 pro is very capable of amazing sound across the spectrum. The sound is on the analytical side, but with some liquidity and musicality. Both ends of the frequency spectrum are enhanced at the extremes, but the midrange is not recessed, and the sound does not have the typical warmth that comes with enhanced bass. The sound is on the quicker and punchier side with excellent dynamic range, transparency, smoothness, and plenty of speed for any genre, but still enough note decay for a natural sound. Clarity and presentation focus are in a class of their own and help present every detail within the music clearly and concisely.
While the NT-6 pro sounds good with lower end sources, carefully selecting a quality DAC and amp or DAP will result in an improved performance. From a technical standpoint, the NT-6 pro is one of the top three in performance of my custom IEM collection and I highly recommend it if you like a bright, engaging, fun, ultra-detailed and clear sound.
[/td] [td=colspan:5] If you like: Bright sound and want ultra-detail with the excitement of enhanced bass, the NT-6 pro is for you! [/td] [td=colspan:3] Links: My full review

[/td] [td=rowspan:2] Source Matching : While the PRM will play nice with some lower end sources, if you are going to spend on the PRM, you should have the source chain to shine.
[/td] [td=rowspan:2] Listening Volume Performance: The PRM performs well at both low and high volume levels, and everywhere between
[/td] [td=colspan:5] Key words: [/td] [td=colspan:5] Summary : Does this $2K CIEM live up to its price? First, being able to tune the sound to your preference solves one of the issues with CIEMs, which is you have to typically buy a non-refundable product to find out the true sound. If you don’t like it, you are out a good deal of money, which is why the ability to not only tune the sound, but try it before you buy is important and has a high value in my opinion, which people ask me for all the time. And when people do ask my opinion, I always recommend they buy based on their sound signature preference and usage. This feature is great.
From a performance perspective, the sound signature of my unit isn’t as important as the sound tendencies and technical performance since you can tune the sound to your liking. Technically the PRM is one of the top performers I have heard, disappearing and letting the music come through with exceptional transparency and realism. The sound is spacious and on the organic side of the spectrum, if just by a bit, and it the warmth is north of neutral. With a laid back presentation, the overall performance is the focus, not the individual instruments, although they are clear and detailed. The PRM performs at a higher level than the $1K UE IERM and up there with more expensive CIEMs I own. The Logitech Ultimate Ears Personal Reference Monitor is an exceptional product, even at its price point, due to the sound tuning feature before you buy and the sound quality you get when the customized version is delivered to you.
