Build

Housing

If the Orion had a world class build quality, then the Lyra is interstellar. The ceramic doesn't just look stunning with it's glossy, smooth finish but the material is super strong and has a LOT of heft to it. I bet this is one of the IEMs that would still be around, working 50 years down the line. 
The choice of ceramic has its advantages, yes, both acoustically and physically, but at the same time has its down sides as well. I found the extra heft a bit of a burden on not just getting a good seal, but also being limited to the types of ear tip that would work with them. The extra weight tends to pull the earpieces out of your ear when using my normally preferred tips. This led me to the conclusion of only 2 choices: 1) using tips that are one size larger effectively making long listening session a little uncomfortable, and 2) only using foam tips. For the purposes of comfort, I defaulted to only using the provided foam tips, which were not bad, but had a negative impact on bass response and soundstage.

Cable

The cable is the same as the Orion, so I will paraphrase, or better yet just copy/paste from that review:
 
This cable is absolutely divine! Can someone say “Bling, bling!”? The first thing I saw where I unboxed them was the cable and it just melted my heart. I believe that it is tinsel covered SPC wire inside. The MMXC connectors are beryllium and copper custom alloy are housed in a clear acrylic moulded strain relief which fuses with the clear ear guides, which have memory wire and can be shaped to suit your ear shape. The cable is insulated is sparkly silver material which feels tough, yet it’s malleable and surprisingly has a minimal amount of memory. The wire is very slippery which means that it doesn’t snag on clothing and it is very light, so light actually that you can’t even feel it’s presence.
The only dislike I have with it is the way the MMXC connectors rotate freely in the socket. It would be so much better if there was an interference fit of some sort to minimise this.
 

Packaging

The Lyra comes in the same beautifully and cosmically designed cardboard box with a different sticker on it to represent the Lyra. It's simple no-nonsense and very effective.

Accessories

The Lyra comes with almost all the same accessories as before; this time instead of a canvas hard case, it comes with a full leather upholstered case with leather webbing and the same sheep wool inner lining. For the record, I absolutely love this carry case.
Campfire Audio include a very nice selection of ear tips that mostly consist of foam tips. 
In the box you get:

1. 3 pairs of rather standard silicone tips (S/M/L)
2. 3 pairs of generic hard foam tips (S/M/L)
3. 3 pairs of COMPLY TX-400 foam tips (S/M/L)
4. A cleaning brush and ear wax prod.
5. A little booklet with all the juice details about the Lyra.
6. A little CA "Fanboy" shirt pin. (That's funny, nice touch!)

 

Sound

All my listening and evaluation consists of various genres of music including but not limited to: trance, house, funk, acoustic, rock, orchestral and electronic.  
Gear used: Audio-gd NFB-15 amp/DAC, FiiO X1, FiiO E17 (PC as transport). Ear tips used are Fidue dual-flange wide bore for deep semi-deep insertion.
 
I'm not sure that I'm the target audience for the Lyra. It didn't gel well with my preferences when I first tried it and it still doesn't gel well with me today. It is a slightly V shaped sounding IEM with a pretty big emphasis on the mid and upper bass frequencies. I also found the Lyra to by quite picky with recordings, masters and genres. It sounds exceptional with very well mastered and non-compressed tracks, but when it came down to normal, everyday listening, the Lyra sounded grainy, thin and lifeless. It's shone best with electronic tracks with cleanly separated sound elements and nothing too complex. Soundstage performance can be "OK", with at times above average, but once the bass starts to overwhelm, everything is muddled together. 

Treble

The treble is my favourite aspect of the Lyra in the sound department. From close listening I can find 2 or 3 peaks, one at 8kHz, one at 9-10kHz, and one at 12kHz. This  effectively means that micro details will be very spot on and very much part of the experience all the time, it's also makes me think that this is a part of why they are so picky with music. Treble has decent attack and bite, with moderate decay. 

Mids

Mids are a bit of a bummer. They just feel much too lifeless. They're thin and grainy on the top end and might be a little sibilant to some people. Sibilance was just under my threshold and felt like it was border lining at times, but I never got the feeling where I had to turn it down. Female vocals are flat and two dimensional, and just don't feel very appealing. Male vocals are a bit better, they pick up a lot of bloomy from the lower end which gives them a pretty thick appearance. But at the same time they seem a bit lifeless and dull. Acoustic instruments are also overwhelmed by the bass thickness with that "bloom" which muffles a lot of the separation between the instruments. 

Bass

Well the bass is pretty big. It's weighty and thick, with lots of rumble and authority. It goes as low as 30Hz audibly to my ear. This is pretty good, but the speed and coherence of the bass is a little lacking. It rather flabby and slow and it leaks quite a bit into the rest of the spectrum.

Housing

Oh the build! The Orion is indisputably the best looking IEM I’ve held in my hand. I’m a huge fan of good machining and the Orion is flawlessly CNC cut with laser precision accuracy to the micron. They’re held together with socket machine screws, a silver coloured aluminium nozzle and MMXC cable connectors. The whole unit absolutely screams “Quality Product” and just for the beauty of it alone I’d pay the $550 price tag, and it only gets better from here. They don't just look great, they also feel great. Even though the housing is a little on the large side, and it does have sharp edges, it's made in a way that feels very comfortable and natural when you position them just right in your ears. They sit well thanks to the earguides and you just forget that they're in.

Cable

This cable is absolutely divine! Can someone say “Bling, bling!”? The first thing I saw where I unboxed them was the cable and it just melted my heart.

Packaging

The Orion comes in a pretty simple cardboard box, what is special though, is what is on the box. The psychedelic and cosmic looking print is gorgeous and adds to the uniqueness of this product.

Accessories

The earphones come is a really nice canvas outer lined zipped clamshell which is lined internally with sheet skin. There is a webbing inside which doesn’t allow the clamshell to open all the way. I found this to work extremely well in practice as it makes sure that the earphone never falls out by accident. I’ve not seen anything like this before.
Campfire Audio include a very nice selection of ear tips that mostly consist of foam tips. I’m not a big fan of foam tips, but I do use them when dampening of sibilance and harsh treble is required, needless to say, they weren’t required here.
In the box you get:

1. 3 pairs of rather standard silicone tips (S/M/L)
2. 3 pairs of generic hard foam tips (S/M/L)

Sound

All my listening and evaluation consists of various genres of music including but not limited to: trance, house, funk, acoustic, rock, orchestral and electronic. Gear used: Audio-gd NFB-15 amp/DAC, FiiO X1, FiiO E17 (PC as transport). Eartips used are Fidue dual-flange wide bore for semi-deep insertion.
 
The sound characteristics of the Orion is borderline reference. It’s quite flat and tame but lacks excitement and sparkle, though were it shines is linearity and sense of space. It has a very good 3D image which makes up for it’s somewhat average soundstage width. The coherency of sound elements are well defined and make for a very enjoyable intimate listening session. I found that where the Orion has all of this pronounced uniqueness and beauty in appearance it somewhat lacks in sound character. Thus the downfall of making a linear sounding headphone. It’s not for everyone but I found them to be technically well versed and I think I would rate them above both the new Jays Q-JAYS, and the Noble Savant. The average consumer who is not a treble-head would surely love these.

Treble

Safe tuning is what I understand the treble to be, and is the main reason I think this IEM lacks character. The treble is too smoothed and is a little slow on decay. I found this to be very evident with live recorded orchestral scores where there is a lot of reverb. The BA’s pick up the echoes and as they build up they start to resonate and ring giving the sound signature a little bit of a hollow or “flangy” character. This does not translate to studio recording though and is not noticeable most of the time.
The rounded treble response means that they are a very good choice for those you like to listen to music loudly. I’ve never encountered any sibilance or harshness. For the most part, the treble is very accurate and true in timbre.

Mids

Mids are separated very well from the treble and bass regions. Vocals are well defined in the head space and feel a little forward and natural. They are a little warm and with the reverb pickup they actually sound very raw and real. Though this feels really great, it’s not a reference type sound and in effect it sounds a bit smudged with male vocals; you can't have it all. This also translates to different kind of acoustics like guitars and pianos.

Bass

Good bass in my opinion starts with good, deep and fast sub bass, and the Orion does this right. The bass maybe a little recessed, but it's good where it matters. Bass guitar really shines through with good roll of the note, and 808 kicks stand out like nothing else. I’m a fan of this type of bass response; it does away with any bloat and unnecessary pomp in the bottom end which gives of a faux punch. What many would be interested is if they react well the EQing of the bass, and that answer is yes. Giving it a boost in the whole region up to 200Hz elevates the Orion to a nicely punchy sounding IEM.

Build

The built, as with all the VE earbuds I’ve tried is much the same. Being as standard earbud as it gets. If it wasn’t for the colour and cable differences you would not be able to tell them apart. These earbuds are like Ninjas in disguise. They look like a normal everyday earbud until you actually listen to them.
The cable on the Zen 1.0 is a clear silver cable which is a tiny bit stiffer than what I’d like, and it’s got a straight connector, but it’s got great strain relief and one of the best neck synchs that I’ve ever used. The cable of the 2.0 is red coloured clear silver cable which is now a 90 degree angled jack and is much more supple now.
Both are very light and feel strong enough to last through daily abuse.
 

Comfort

I have very small ears and these, like the VE Monks, sit in my ear surprisingly very securely. On the odd occasion I do need to readjust them when turning my head, but for the most part they are very good. Weight plays a big role here.
 

Accessories

You get a hard ball shaped clamshell carry case witch is strong enough to protect it’s contents. You also get some full sizes and donut earbud foams. You also get shirt clip if you need one. Nothing too special. You’re really not paying for fancy accessories or an unboxing experience.
 

Driveability

Whilst you can get them loud enough from a mobile phone, I would not suggest it; the sound is dull and just sound wrong. I did most of my listening from my Audio-gd NFB15.32 and the Ve RunAbout for portable use. I did try it with the FiiO X1, FiiO E17, xDuoo X2 and xDuoo X3, but all seemed to struggle to power these beasts.
 

Sound

The sound of the two products is so different that they may as well be 2 separate products. I will describe both of them with a few words off the top of my head just to paint a picture of how different they really are:
Zen 1.0:   Cold, flat, analytical, refined, open and dynamic. Zen 2.0:   Natural, organic, warm, open, detailed and dynamic.
 
As I have mentioned previously, the 1.0 is a flatter and more analytical approach, which to me is rather boring. I would have been very impressed with the 1.0 if I didn’t hear the Monk before it. It still is a great sounding earbud when compare to the previous experience I’ve had with other earbuds.
 

Treble

Zen 1.0
It’s not the fastest treble you’ll hear but it’s very good for an earbud. It’s quite detailed and extends very well. Though I do feel there is a bit of a dip somewhere in there that makes it slightly blunted and too quick on decay.
 
Zen 2.0
The emphasis here has been shifted somewhat which brings back that shimmer that was missing in the 1.0. But the speed has decreased a bit which puts a bit of a veil on the detail. In return you get a more airier presentation.
 

Mids

Zen 1.0
The timber of the vocals and acoustic instruments is very good and sounds pretty accurate. There isn’t a particular tilt or colouration that sways it in either direction. The are though a little recessed and lack some detail.
 
Zen 2.0
The Vocals are warmer and more textured and slightly more forward. It’s a little less detailed than the 1.0 but more present and feel more alive with a bit more reverberation.
 

Bass

Zen 1.0
The bass on the 1.0 kind of reminds me of balanced armature bass. It’s fast and detailed but lacks authority and thump. Nonetheless it’s great for an earbud and it reaches quite low.
 
Zen 2.0
It has an amazingly addictive bass note that’s textured and detailed. It’s authoritative and has substantial kick. It’s not bass head quantity but it’s nearly perfect to me.
 

Soundstage and Imaging

Both have quite similar soundstage and imaging performance. It’s really wide and deep and you get a very immersive out-of-head experience. The Zen 2.0 is better as it is slightly deeper and more accurate. The extra warmth makes the air feel more natural and realistic.

Packaging

The box is pretty much EXACTLY the same as the Titan 1, except that it has Titan 5 written on it. It really is very much the same including the accessories. In fact the only new addition is the stabiliser hooks or as I call them “wings”. These are a great addition for those who have fit problems wearing them cable down. I never felt like I needed them, so never used them for the Titans, though have tried then on the Titan 1 just to see how it works with those extra holes; it work brilliantly for those curious.Because the packaging is exactly the same I will quote from my Titan 1 review:
 
 

Design

The design has been slightly tweaked with the Titan 5. DUNU have dropped the ultra open configuration and have opted to use only 1 port-hole. Many users were complaining about the lack of isolation, and of course this was the obvious fix, and it worked a treat.
Another change was the inclusion of a removable cable. This is one of the best feature any IEM company can implement that would increase the value of their products dramatically. A removable cable not only means that you can replace it in the unfortunate event of the cable breaking, and I know it happens to even the most expensive IEMs and it’s happened to me plenty of times to know how important it is to have this feature. The cable uses quite a hefty looking jack which houses an MMXC connector. It feels very durable and tactile and the connection is very secure.
One more complaint that people had with the Titan 1 was the fact that it was only designed to be worn cable down, and wearing it cable up, or over the ear, meant that you were forced to swap the channels around, which was not a huge issue but made me a little OCD thinking about it, so I never did it. With the addition of a removable cable, you are now able to switch the channels around to suit both cable up or down to your preference and listen to the music as you wish till you heart is content.
It does show a lot about the company when they listen to the criticism and instead of defending their products they set out to fix those issue to come back with something better.
One more thing that needs a mention is the fact that the earpiece housing is now made of stainless steel making it noticeably heavier, and holding the whole Titan 1 in one hand (earpieces, splitter, cable and jack) and just the earpieces of the Titan 5 in the other feels about twice as heavy. Since it sits very snug and securely in me ears, I don’t find this to be an issue, but it’s something to note.
 

Cable

It is a shame that the Titan 5 didn’t come with a remote/mic cable. It was one of my main gripes with the Titan 1 and I guess it was not asked for enough to make the cut. Of course, it being a removable cable means that I could just buy an aftermarket cable that has a remote.
Nonetheless, the cable is an undoubtable upgrade to the Titan 1. Visually, it’s almost exactly the same. It loses the fabric sheaving which I’m not a big fan off. As well as the Y-splitter, neck cinch, and jack are now (anodised?) black with a very nicely machine chamfered on the edges to give it a silver accent. It retains the brilliant strain relieves and their patented cable lock, and more importantly and rubber material. The rubber sheaving of the Titan 5 is probably the best cable material I’ve had the pleasure of holding in my hand. It feels soft and strong, and it does not kink or retains any memory, as well as it’s very supple and doesn’t have any microphonics or mechanical noise at all. Top marks for that! It love this cable so much that I actually have plans for a project to make a MMXC to 2 pin adapter so I can use this cable with other IEMs.
 

Isolation

The isolation is as expected: exceptional. The removal of most of the port holes means that you get much less sound leakage in and out. It’s not the best isolation, average at best, but it is adequate for your daily commute on public transport. It's definitely an improvement.
 

Driveability

The Titan 5 is easier to drive than the Titan 1, which is great if you ask me! I don’t have any problems powering them with my phone and they do scale nicely with more power. They paired exceptionally well with the FiiO X1 and xDuoo X2 & X3, and even better with the Audio-GD NFB-15.32.
 

Sound

Along with all the other numerous positive changes to the Titan 5, the sound has also been improved for the better in my opinion. The Titan 5 retains the slightly V shaped, fun, yet balanced signature, but with a smoother and slightly more punchy and fun attitude. There are a lot of aspects I like with the way the Titan 5 sounds.
 

Treble

As much as I loved the Titan 1, I had a little issue with harshness in the lower treble region which made it hard for me to enjoy them for long. Being a CAD drafter professionally means that being mentally fatigued is a very bad thing even if it’s just slightly. The Titan 5 does away with this harshness by smoothing out the lower treble region and pushing the emphasis not on one single region but along the whole treble spectrum, which in effect makes for a more coherent and dynamic delivery of percussion elements and give a much more comfortable listen for almost all genres. Because there are no particular peaks that I can notice in the treble region, it may seem to some that there is somewhat a veil on the detail retrieval. I would say that this is akin to the “Sennheiser veil” as some call it, where the HD650 has actually very good detail retrieval, air and sense of space but it is not portrayed in a forward manner, rather a smooth and laidback way which I really like, and yes I would say that they do sound somewhat like the HD650 from what I remember them.
 

Mids

The midrange has very nicely filled out and smoothly textured. It sounds particularly good with strong female vocalists. There is a very nice natural timbre but some elements can sound a little washed out. For instance male vocals sometimes seems a little too smooth. This makes male dominated tracks sound less detailed than the rest of the music and it kind of takes away from the harmony of the composition. Nonetheless, most of the time it is not an issue, and I found myself really enjoying listening to even the most flawed recordings as I slaved away at work. The signature is just too smooth not to enjoy.
 

Bass

The bass is also much improved. It now hits harder and goes deeper with a much meatier note. It’s a little more mid bass orientated as opposed to the Titan 1, and the bass may leak into the lower mids just a tiny fraction, but what it does is put this really slight bloom on the signature that warms it up and adds to the smoothness. I did enjoy it quite a bit. It’s not for bass heads, but a safe bet that most will like this type of bass.
 

Soundstage & Imaging

As mentioned earlier, because there is now only 1 port in each earpiece, this means that the soundstage performance does get somewhat of a hit. It’s smaller and more intimate, but this is not necessarily a bad thing because the imaging performance is still as exceptional as it was if not better. I found myself actually using these over my full sized cans when watching movies and playing games. Playing games in particular was a very enjoyable experience as you still get a good enough sense of positioning, this coupled with the comfort and security in the ear made for some great long gaming sessions.

[size=24.57px] Design [/size]
 
The overall design of the Monks is as "standard earbud" as it ever gets. There is no packaging what so ever, and truth be told, it really doesn't need it. The housing is made of black plastic which is extremely light at 2 grams for each housing and a total of 17 grams for the whole unit including the cable. Being so light means that you can stick them in your ears and just forget that they're there, and this is what happens to me when I use them at work every single time; I put them in, press play and just work away, and time just flies away.
Because it is an earbud, the isolation is non-existent, meaning that they are extremely good when using them where you need to interact with people or even just hearing the world around you, like taking a stroll or riding a bike. This of course means that if you like to listen to music loudly, it will leak a lot of the sound out.
The cable is of really good quality; it's soft and bends very well without memory or kinking. It's easy to untangle and most importantly it feels like it will last a lot time. The jack is somewhat big and so is the strain relief, which also gives the impression of longevity. 
 

Comfort

Fit in you ear is of course dependent on your ear shape. I have particularly small ears and the Monk sits inside quite loosely but they seem to stay in very well. I've not yet had them fall out even once. But, I do need to readjust them from time to time if it pivots in the ear from movement. 
 

Drivability

The Monks are extremely easy to drive but do require a little extra volume to get them to the same listening volume as IEMs. This is of course because they do not seal. Nonetheless, I can drive them no problem with my Moto G and they sound just fine. However, they do scale up quite nicely with more powerful gear, and I notice a huge improvement in imaging performance when using my Audio-GD NFB15.
 

Sound

You maybe sitting there and asking, "But, Igor! Where exactly are all of my $5 really going?", and the answer is here. This is where all the fuss is located.
The Monk is by far the best earbud I've heard to date, and yes, I've been hearing a lot about VE's TOTL earbud the VE Zen, but I have not yet auditioned it and my statement stays true at the moment of me writing this review. 
The way I like to describe the VE Monk sounds is like listening to decent bookshelf speakers, or maybe even a full sized open headphone. To describe the Monk in a few words, it would be: natural, organic, open, immersing and detailed. The overall sound signature is quite balanced, somewhat low to mid fi in terms of clarity, and with a really awesome soundstage that is very immersing and natural.
 

Treble

Treble is clear and present, without any noticeable peaks or dips. It's detailed enough to get pops and static, but a little cloudy in the lower regions. No sibilance what so ever, even in sibilant prone tracks. Cymbals shimmer but are a little smoothed. The treble maybe a little slow but it's enjoyable.

Mids

Mids are maybe just a tad forward but mostly neutral. They are full and warm but can get a slightly chesty, but not too much and can get a little shouty at high volumes. Vocals and acoustics is where the Monks really shine with it's smooth and organic timber for both female and male vocals. Dare I say that there is a little bit of the Grado sound going on here. 
The transition from the bass and to the treble is impeccable and extremely smooth.

Bass

The bass is great and very impressive for an earbud. There is a lot of warmth that fills the whole spectrum. Mid and upper bass is very neutral and is reasonable fast and punchy. Of course, because you cannot really get a proper seal with an earbud, this means that the bass rolls off quite dramatically after around 100Hz, so sub-bass frequencies are loss completely, even at high volumes. 

Soundstage & Imaging

You get the full concert experience when you listen to live recordings, especially orchestral recordings. The soundstage is really wide and deep, but in a very natural way. I don't really know how to put my finger on it, but I think there's some kind of resonance or reverb going on that makes them sound super open and very accurate and articulate in placement. This is probably what I'm mostly fond about with the Monk, as I am a huge sucker for great imaging.

Packaging & Accessories

The Cayin N6 comes in a very nicely presented box. You can tell that Cayin has gone through a lot of effort to give the N6 the dignity it deserves. Very nice hard cardboard and velvety material, and beautiful pallet of colours gives it a soft yet elegant presentation. To save you from reading a bunch of mumbo jumbo, please have a look at the photos because in my opinion, these words cannot describe how nice the packaging is, and keep in mind that it looks and feels much nicer in person.
 

Accessories that come in the box are:

1. Micro-USB cable.
2. A 2 pole 3.5mm (1/8") TRRS to RCA coax adapter for Digital SPDIF.
3. A very nice carbon fibre print keyring
4. A USB stick with drivers
5. A screen protector.
6. Documents & reading material: Quick start guide; A card with button layout, and other info; warranty card.

 
A couple of line out cables would be nice at this price range, more specifically, a 3.5mm to 3.5mm and a pair of RCA cables would've have been really welcomed.
 

Design & Build

The design of the N6 is a bit of a hate it or love it situation. I'm a bit of both, but mostly I love the design. Aluminium top with a nice acrylic carbon fibre printed back is very appealing to me, and it is pure eye candy. The meeting of the acrylic at the back leaves a really sharp edge, one that could mean the end of the nice finish if you were to accidentally drop it onto hard ground. As well as it is so sharp to the touch that I find my self sometimes being very careful not to cut myself with it, though this is mostly a subconcious reaction as I don't think it's sharp enough to cut skin.
The screen and button layout is a bit of a miss for me. I think the whole round screen idea is a bit of an eye sore and in my humble opinion unnecesarilly too big, which spills out to the edges of the unit and makes it even wider, which the unit is already REALLY big. The screen is also very reflective and somewhat dim makes for visibility is the sun pretty poor.
The button layout was also very hard to get used to and I still struggle to memorise it to this day. To me, this would be a bit of a deal breaker on it's own.
Up = back; Down = forward; Left = back; Right = play/pause. Very unconventional.
 
I'd also like to mention that this unit get's really hot. In one listening session I had where I listened to it for almost 5 hours straight it got very hot in my back pocket, to the point where I had to take it out before it branded my a** forever. 
 

User Interface

The operating system looks very suspiciously similar to FiiO's. Not sure if this is an open source system that they use and share or one is copying the other, I don't know. What I do know is that it is one of the better user friendly systems around, especially when the system uses a scroll wheel. The N6 has somewhat a scroll wheel on the left side, but it is not good enough to jog through hundreds of songs. I found myself taking a long time to search through my catalogue to pick a specific track and ended up just defaulting to forever using shuffle all and be done with it. This is further exasperated me by the fact that everything you do has a lag or delay to it, including just picking a song to play or going through the menu. I do hope that this is just a software optimisation issue. Going through all the menus felt like a chore to me.
 

Battery Life

The battery in the N6 is humongous and for good reason. The N6 is a power hungry behemoth. Battery drains quite fast and I think the longest non-stop listening time I got with the N6 was around 4-5 hours before it was down to around 20-30% which is where I would charge it. Charging it through a normal USB port takes forever and if you can, I'd suggest you use a tablet charger; something with more than 1A of current. 
 

Input & Output Interface

I found that the N6 works extremely well as a DAC. It is extremely easy to setup, and drivers can be found either on the provided USB or online. The line out is also very clean. I did not get the chance to try the COAX unfortunately.
 

Equaliser

The N6 has a 10 band EQ which works surprisingly well. I didn't play around with it much as the headphone output is actually pretty transparent as it is. But when I did test it the frequencies reacted accordingly without noticeable noise and distortion. 
 

Power

The Cayin N6 has more than enough power to drive all my headphones and earphones to good listening volumes and more, and with good authority. Bass never felt sloppy at all, and I was pleased with the way it handled itself.
 

Sound

This is the part that matters the most. The Cayin N6 is one of the most detailed and cohesive sounding DAPs that I've previously auditioned. The way it delivers the sound is very accurate and with composure. Bass frequencies delve deep and had consistent speed and coherency to as low as my headphones can go. The mid ranges felt lively and, for the most part, accurate and full with a bit of warmth and glow. Treble response was smooth and detailed with extreme accuracy and speed without getting edgy or digital.

[size=24.57px]Packaging & Accesories[/size]

The Cozoy Aegis comes with very nice "Appleseque" packaging which mirrors the Astrapi packaging. It's very good packaging, being very minimalistic and eye catching. I am sure that if you had this box in an Apple store, it will sell like hot cakes. 
Inside the box you are greeted with the Aegis right off the bat tucked into a foam cut out with a lovely velvet top. It's very clever that they have made a pull ribbon to pull on to pop the Aegis out without having to struggle to claw it out of the foam cutout as it is in there very tight. You can also use the ribbon to pull out the foam bit to get to the goodies underneath. 
 
Inside the box you get:
 

1. Black warranty card with silver writing, which doubles as a spec sheet and quick start guide.
2. Cozoy Aegis
3. A 30cm (12") MicroUSB to MicroUSB
4. A 30cm (12") iOS Lightning to MicroUSB cable
5. A 30cm (12") USB to MicroUSB cable

 
 

Design

If looks could kill, then you should beware the Aegis. It is B-E-A-U-TIFUL! Sharp corners, brushed aluminium, black accents; like a Tanto blade. It looks like precision machining too. The body has been milled from a block of aluminium, and this precision is also been transferred across to the connectors because they are a little tighter than normal, making the connection of the MicroUSB cable and 3.5mm headphone jack very secure. This device was definitely made for portable use and that it does spectacularly.
 
 

Compatibility

As it stands, from what I've read on the forums the Aegis is compatible with iOS, OSX, Android, Windows and Linux. Personally I've only tried it on my Moto G XT1033, my PC at home which runs Windows 10, my PC at work which runs Windows 7, and my wife's tablet which also runs Windows 10. From what I can notice is that the Aegis preforms better with devices that have a higher current output, but saying this, it is no slouch running from a phone. 
There is a common problem that I've read from a few users because of it's logarithmic volume steps. This is actually a bit of a quirky thing because I only get a problem with this on my work PC, where it feels like there is only 5-6 volume steps. On my home PC and the tablet this is more like 10 steps, but funny enough, on my Moto G is get the full range of volume steps which I've got set to 30 steps. This could be the fact that I am running a custom ROM and kernel. Either way, I don't find this to be problematic at all with any of my IEMs, which includes BA driver IEMs.
 

Drivability

I have driven everything I own from the Aegis with very good results. The Aegis works especially well with warmer headphones. I don't have any particularly hard to drive headphones so it's hard to comment on this subject. In fact I find it to be overpoweringly loud with almost everything when it is set to 100% volume.
 

Sound

This is the hardest aspect of all the gauge on DACs and other source devices as the whole point of them is to stay as close as possible to being transparent and true to source. The Aegis did this very well. 
I would say that the Aegis is leaning on the colder more analytical side of the spectrum, but with a bit of a warm tint as well, which fills in vocals very nicely. When you get good synergy with a headphone you get a very "alive" performance, where vocals sound very real. There are only few DACs where I've actually felt this. When driving the Aegis a little louder then usual I've found it to be a bit bright and grainy in the mid to upper treble regions, this could somewhat sound digital, but works out well with music that has a lot of nuance, like pops and crackles, or filter noise. 
It doesn't have the blackest background but noise is only heard when nothing is playing and only with sensitive BA driver IEMs. 
Overall, I was more than satisfied with the sound performance of the Aegis.

Packaging & Accessories

This one probably one of the best unpacking experiences I've had. The presentation of the packaging and sheer volume of accessories that comes with the Noble Audio Savants blew my socks off. It is just layers upon layers of packaging that screams quality that just left me saying "Wow!" louder and louder as I unpacked the Savants further and further. I think that they're just showing off! But it's is definitely "$600" type packaging; no cent was spared here.
 
In the box you get:

• 2x Noble Audio stickers (Glow in the dark? Maybe.)
• An absolutely awesome Pelican case.
• 4x sets of ear tips: S/M/L standard dual flange, S/M/L finned blue core, S/M/L red core Sony hybrids, and S/M/L foam.
• An aluminium owners card (I can only guess it's for warranty claims or just to wave in peoples' faces.)
• 2x rubber bands for stacking.
• And lastly, a cleaning tool.

 
Not too shabby at all! And to their credit, they've fit all this in that tiny Pelican case. Well done!
 

Design & Comfort

Noble Audio states that the Savant are built with "Signature Noble universal form factor". This form factor for the most part is very well designed but maybe be a bit big for some some users. They do stick out of the ear a little far and the result is that they do tend to pick up a bit of wind when taking them outside. Also the bore is a little bit bigger than usual meaning I could not get them to insert very far into my ear, so I had to settle with using my favourite Fidue dual flange tips which work very well with the Savants for me. 
The casing is made from pretty smooth, strong and light plastic making them actually very comfortable to wear for a long time. There are no sore spots to mention and they sit very securely in the ear, YMMV. The provided cable has a memory wire in the ear guides which adds to the comfort and security of the Savants. A very simple plastic sleeve is used for the neck cinch and it works extremely well. 
 
The only thing that I must mention is that I get a very tight vacuum seal (AKA driver flex) every time I initially put the Savants in my ears, this was a little painful the first couple of times, but my ears adjusted to it. Make sure you don't yank them suddenly out of you ears as that could have very bad consequences to your inner ear.
 

Cable, Jack, Splitter & Mic/Remote

I personally am a very huge fan of the cable. The braiding is done very well with a very nice round quad braid up to the chest and then a simple twist braid to the shell connectors. The Y-splitter is a simple piece of clear heat shrink; I really wish it was black though. The jack is unfortunately straight, but it is smaller profile than usual. I do have a little gripe with the jack, and this time it's not because it is straight, but because it is very slippery, and people with grease/sweaty finger syndrome will have a bit of trouble unplugging the jack from devices that have a good grip on the TRS tip. Also the strain relief is a little too small, but I'm sure this will be fine in the long term. The backs of the 2 pin connectors have a colour on both channels to tell you which side is what; blue = left, red = right. They also sit very firmly inside the female connectors on the shells.
 
[size=inherit]There is no remote or microphone on the cable, which is a bummer. But guess what! Removable cable remember!? That's right, you've already spent $600 on an IEM, what's another $50-$100 on a cable that only you would enjoy! [/size]
 

Isolation

This is one aspect that the Savant really excels on. The isolation is sublime! You pop them in and press play = good bye world. You don't even need to have the volume up high. I can have these turned down to background music levels and still no hear the world around me. This works the other way as well. Once they're in your ear, no one can hear what you're listening to. Full marks no doubt!
 

Sound

Now here brings me back to the meaning of Savant. I really don't know which aspect of the earphone they were referring to. The Savant handles nearly every part in the sound department with ease. With the correct source pairing the detail retrieval goes to reference levels, shy of analytical. The Savants are also extremely dynamic and coherent in the way it presents every sound element. Everything just feels effortless. The tuning is done with great care to keep everything balanced and just right. To me this this kind of sound signature is nearly perfect in timbre. 

Treble

I find the treble to be very well tuned for a long and comfortable listen. It's not the fastest treble I've heard, even maybe a little slower than the average BA earphone, and maybe just a little bit recessed. I cannot find a bit of sibilance, dryness or harshness. This is the kind of treble that I am a huge fan of, and is the reason I really loved the Havi B3 Pro 1 so much, and if you are a fan of the Havis, I can safely say that the Savant would be the perfect upgrade to them, as they have a lot of similarities.

Mids

Again I will utter balance. The transition from treble to mids is smooth. There is maybe a little but of recess in the upper mid range which can make some female vocalist pushed back in the soundstage, this is not very prominent though. Female vocals sound natural but a little blunted or subdued. Male vocals suffer a little bit of the same. There is not enough lower mid presence to give them a full and chesty note, but this is not a bad thing as that exaggerates them.
The mid range is very linear and balanced to suit the rest of the spectrum without pushing any elements in front of each other. It is designed to be very coherent and as close to "correct" as possible.

Bass

The bass here is a little deceiving. It sounds full, engaging, deep and just a tad forward. But it does all this without a true visceral punch. It kind of feels like faux bass. It lacks the organic elements of good bass. Nonetheless, the bass on the Savant is good. It's relatively fast and coherent for the most part, and can bring a bit of rumble when called upon. 
The bass region can be EQ'ed for a little bit better results, but be warned that it can only be push so far before it starts to distort quite a bit. I cannot go above 2db bass boost on the FiiO E17 hardware EQ before it starts to effect the rest of the sound spectrum, especially the treble.

Soundstage & Imaging

The soundstage on the Savant is not big, but it is bigger than average, and not just bigger, it feels very natural with a really satisfying amount of air. The imaging performance is also very good. Listening to both studio and live recorded tracks leaves you with a very good impression, and this imaging performance is mainly the reason why the Savants sound so natural, effortless and dynamic in it's presentation.

Packaging & Accessories

The Fidue A65 comes in a typical Fidue styled box, except this time is white[size=inherit] with the signature Fidue green square with all the juicy details on it. As well as the very nice glossy pattern that wraps around the box. There's no picture of the A65 anywhere on the box which is quite a surprise because I personally love the way that they look. On the back of the box you get all the info in English, Chinese and German as well as contact info, a serial number and a QR code. [/size]
 
Accessories are pretty much the same as the A73; you get 3 pairs of standard silicone tips and one pair of the Fidue double flange tips, which I actually are my favourite tips for quite a while now, but these ones come in a softer opaque grey silicone. With it you get a very nice velvet carry pouch, shirt clip and a rubber cable tie. With it you also get a warranty card, which you probably won't need as they are built like a tank.
 

Design & Comfort

I'd like to say that these indeed feel very premium for the price range. Made from what I can only guess is aluminium and it's actually quite hefty and has some weight to it, but this weight doesn't translate to an awkward fit. They are actually a very comfortable headphone, worn both cable down and over the ear. While you do get some mechanical cable noise when worn down, this disappears completely when worn around the ear. Using the double flange tips they sit in my ear very well and I can listen to them all day long without getting sore spots.
The housing design is quite beautiful. It's a weird kind of organic triangular lofted shape which tapers down towards your ear. The main body of the shell is a very flashy satin rose gold, the back is a brushed aluminium and the nozzle is a glossy gun metal colour. 
 

Cable, Jack, Splitter & Mic/Remote

The cable is exactly the same as the A73 except for the internals are made from hi-end 7N-OFC, so this section has been copied straight out of my A73 review.
Fidue A73 Review

The cable itself is a soft silicone or rubber which insulates some round twisted inner core wires. It gives a heat-shrink type of vibe. The cable is very rubbery and “grabby”, by that I mean, they grab everything they drag on; that includes clothes, skin and hair. You do get used to it and it does have a positive and that is they sit very nicely on you head around the ear and don’t move around.  The cable also twists a lot and grabs onto itself making them quite a nightmare to untangle if you didn’t coil them properly when storing them away.
There is also no neck cinch which is not a huge deal breaker because what I do is just twist the wires around the Y splitter a few times, and bingo! DIY neck cinch!
 
The jack, Y splitter and the remote. All look quite the same. They’re pretty much an exact copy of the Xiaomi Piston design with the machined groves but it works very nicely and looks fantastic. And yes that’s right, I said remote. There’s a mic and remote on this unit. Halleluiah! Unfortunately it didn’t work with my phone or the FiiO X1, which is a huge sad face for me, but I’m sure it works absolutely fine with other devices especially stuff from Apple.

Isolation

Isolation is actually very, and I mean VERY good. It blocks out possibly more than any other IEM I've listened to. Writing this review, I can't even hear the keys on the keyboard click whilst I'm listening to music. And most importantly, it blocks out my noisy kids! It works similarly visa versa; although it is a ported design, having just one port on each channel, I don't get anyone complaining about noise coming from my cubicle at work. Full marks for this.
 

Sound

The Fidue A65 is actually quite articulate at presenting all ranges, and does great with mostly all genre I've tried. To describe the A65 in a few words off the top of my head would be: rich, warm, soft and smooth. It doesn't have any particular sections of the sound range which has been taken out and looking at the FR graph you can see this clearly. The sound range is relatively flat and only has about 8 db difference between the whole frequency range. This is not an easy feat to achieve. 

Treble

Treble feel somewhat blunted because there are no spikes or elevations anywhere in the treble to bring lots of air, sparkle, or energy. This is not such a bad thing as this means that the listening experience is very comfortable, having absolutely no sibilance or fatigue at all. All the treble is absolutely there but it is not presented to you in a forward manner, but a less is more type way. It does not take away from clarity or resolution of the recording but what you miss out is the really micro detail that some people love. The details like clicks and pops, the fuss you here when an effect is applied to a sample, and all those things that aren't necessarily recorded on purpose; ie. all the faults you here in music production, making them quite forgiving.

Mids

The mids are absolutely stellar! They're bold, they're warm and chesty, they're visceral and feel oh so alive! You get this great sweetness in the sound that I personally enjoy which makes my spine melt on certain tracks. Male vocals have this raw note to them like you're sitting in front of a studio monitor. Female vocal, though, sound a bit distant plain, but smooth and enjoyable nonetheless; they could do with a bit more treble presence. Acoustics like guitar, piano and sax sound as good as ever, with great energy and fullness.

Bass

Bass response is fast and accurate. It's really flat but hit hard when needed. Bass goes as low as 28Hz and fall off a cliff there after. It does elevate slightly as it goes higher into the mids, but the transitions is quite smooth and works very well. 

Soundstage & Imaging

The sound stage is above average. Where the A65 really shines is the imaging. There is a great sense of space and separation, with pinpoint accuracy. Sound elements are layered extremely well, with great sense of height and distance. Because of this I actually really enjoyed the A65 with trance and down tempo music. It gets extremely immersive at times.

The Fidue A73 comes in Fidue style, that is, it’s well presented and has a lot of flashy details on it. Black with the signature Fidue green square with all the juicy details on it. As well as the very nice glossy pattern that wraps around the box.

Not going to hang around here too long.[/size]
 
Accessories are unfortunately quite scarce. You get 3 pairs of standard silicone tips and one pair of the Fidue double flange tips, which I actually are my favourite tips for quite a while now, but these ones come in a softer opaque grey silicone. With it you get a very nice clam shell carry case, shirt clip and a rubber cable tie, as well as a warranty card. It’s the exact same amount of accessories you get with the A65. I’m quite baffled by this decision. But OK. I hope they saved the money to bring us a more premium product instead. But I do feel like a pair of ear guides and maybe some extra tips or Comply foam tips would’ve been good at this price range.
 

Design & Comfort

The Fidue A73 is completely different to their previous A71, and I mean completely. The A71 had a dual dynamic driver setup with was a very unique separate chamber, sort-of a jet style setup where the driver on the back fired around the driver in front. The A73 uses a more traditional dynamic plus balance armature configuration. And not just the configuration is different, they look like completely different products, and I’m really loving what Fidue is doing with their current product line up in terms of looks.
The A73 carries over the outer shell styling of its big-daddy-o the A83, and I think that its absolutely stunning, and the right direction to go. The top of the shell is cast aluminium that has this really awesome looking ridge styling; kind of looks like a wing. The rest of it is made from a really light, glossy plastic which is see-through red. When you shine a light through it at just the right angle you can see all the guts in all their glory. I personally love this look. Because they’re not just beautiful but they are also super comfortable. The plastic on the ear side is exactly the type of idea that works because it not only looks good but is absolutely 100% practical for its the purpose. Glossy plastic on skin is warm and soft and the shape of it sits perfectly inside my outer ear. The Fidue double flanges fit absolutely perfect in my ear and I’ve been waiting to get my ears on them again as I lost these ear tips from my A71 box and I was very sad because they were my all-time favourites. These new tips are made from a softer rubber/silicone and are grey in colour, as opposed to the black silicone you got with the A71. Great job to the Fidue R&D team, I hope they got themselves a bonus for their splendid work.
 

Cable, Jack, Splitter & Mic/Remote

The cable internals are made from hi-end silver plated OFC, though the sleeving[size=inherit] is my least favourite part of the A73. The cable itself is a soft silicone or rubber which insulates some round twisted inner core wires. It gives a heat-shrink type of vibe. The cable is very rubbery and “grabby”, by that I mean, they grab everything they drag on; that includes clothes, skin and hair.

Unfortunately it didn’t work with my phone or the FiiO X1, which is a huge sad face for me, but I’m sure it works absolutely fine with other devices especially stuff from Apple.
 

Isolation

Isolation here is splendid. I find them hard to use at work because they block everything out, especially when my manager tries to get my attention. But I kid of course, I find this to be a bonus! The Fidue A73 blocks most of the outside noise very adequately and doesn’t leak a lot of sound out despite having 2 ports on each shell. The BA drivers however do blast a lot of high frequency sound out when you don’t have them inserted in your ears. Top marks in this department.
 

Sound

We’ve found ourselves in the most important section, and you probably thinking to yourself, “Too many good points, nothing is perfect, they must sound like Schiit”. Oh how wrong you are, my friend. They are absolutely divine! In a few words I would describe them to be: Fun, detailed, punchy, balanced, full, spacious and laidback. They’ve got it all.

Treble

Treble is extended but not super elevated. It has this really nice spike in the upper treble that gives it this very open and detailed sound. It never get fatiguing and I can listen to them all day long. The BA driver does a very fine job. There is lots of sparkle and sense of air. It’s very sensitive and can be quite revealing with some recordings. You can hear noise from effects applied on loops you don’t normally hear, and vinyl rips actually sound like you are listening to a really bad vinyl because you hear every single speck of dust the needle runs over. I actually haven’t heard this much detail since the Havi B3 Pro 1 and I actually think that the A73 has just a tiny bit more detail that a dynamic driver just cannot produce.
There is just a little bit of track induce sibilance is the “S” notes because of the peak on the 10kHz region, but most of the time this is non-existent.

Mids

The mids are not the strongest point on the A73 but they’re pretty damn good. Mostly because they mesh so well with the rest of the spectrum. Vocals are place right in from of you, and that’s exactly where they need to be; not behind or far in front, they need to be right in your face, and that’s exactly where they are here. All vocals and acoustics are full and accurate in timbre, not getting dry, grainy, shouty or brash. I wouldn’t call them perfect, but balanced and neutral would be the best way to descript them.

Bass

I’d like to start off by giving the dynamic driver a round of applause. The bass is probably my favourite part of the A73. It’s big, it’s full, it’s fast and most importantly it goes down low. Using SineGen to sweep frequencies I can actually hear the drivers pulse at 18Hz and at 24Hz there is a lot of SPL and it feels like I need to pop my ears. It’s all there all the way up to the midrange. Not elevated in the mid bass, but the same level all the way. It hits hard, it rumbles and it complements the mids very nicely, doing all this without masking any of the detail. It’s quite the feat but the A73 has got it right.

Soundstage & Imaging

The sound stage is amazing. It’s wide and there is a lot of layering not just left and right but up, down, forward and back. It’s not distant like the Havi B3 Pro 1, and I actually prefer it this way. The B3 Pro 1s give you this really surreal and distant experience like everything is so far away. The A73 keeps that feeling of everything in its place, but without pushing everything away from each other, they keep all the elements together, playing together, in harmony.

Packaging & Accesories

The Titans come in a medium sized box; dimensions are 13cm x 17cm x 5cm. It’s very well presented. On the front you are shown exactly what you a purchasing. Everything is well contrasted, bright writing on black background: everything stands out very well. You get all the relevant information in different languages. Very nice.
Under the front flap there is some background information about the Titans, including the frequency response diagram to show you what they’re trying to target and what difference a titanium driver makes compared to a standard driver unit.
They also included a little plug for a Ukrainian band called “Max Barski”. Quite the coincidence since I was born in Ukraine.
Behind the little window you’ll see the beautifully designed housings of the Titans. Open the door and you are presented with 3 pairs of what looks like Sony hybrid silicone ear tips and a wonderful protective box. I must say that this is by far the best protective box I’ve seen to date that comes free with an IEM at this price. It’s made of hard plastic and has a sturdy locking mechanism to keep your already heavy duty looking earphone in tip-top shape so you can chuck them in your bag without any worries what so ever.
Additionally, underneath the plastic holder you get another 6 pairs of ear tips: different colours and styles of more of the Sony hybrid “clone” tips and a set of standard black tips, a shirt clip, and a 3.5mm (1/8”) to 6.3mm (1/4”) gold plated adapter. And of course, you get a warranty card which also has a maintenance log for all your warranty claims.
 
 

Design & Comfort

The design of the Titans is very robust, futuristic and industrial. The housing looks to me like it is machined from a single piece of aluminium. It’s quite a funny design because from day one my wife called them the UFO earphones, and that’s what I’ve been calling them because of its strange “flying saucer” shaped design that integrates the design principles of both earbuds and in-ear monitors. Strange it may be, but looks may be deceiving, and that’s exactly the case here; they’re some of the most comfortable cable down earphones that I’ve had the pleasure of putting in my ears. Yes! They are very comfortable, which is surprising for a metal ear piece sitting in your ear. Unfortunately they’re not designed for wearing over the ear, which is a bit of a bummer, but because they’re so comfortable wearing down, and they stay in like glue with the correct tips, that the thought of wearing them over the ear goes away very quickly.
The housing sports 11 port holes on the housing and 7 holes on the nozzle. In my humble opinion this is a double edged sword. On one hand it means that less dirty will make its way inside the housing, but on the other hand it means that if debris does indeed get inside, good luck cleaning it out. But despite all that, I personally think that it makes the unit look a tonne more badass and industrial.
 
 

Cable, Jack & Splitter

The cable here is brilliant! I don’t know what they’ve done with it, but it just does not tangle. I can wrap it into a ball, chuck it in my pocket and after going to my destination, pull the clump of wire out, hold one wire and pull on another, and in most cases, the cable will just twist, turn and unravel itself like magic. It maybe the fact that the cable is made from 2 different materials. The cable from the jack to the Y-splitter has a fabric sleeve and the ear piece cable is a supple but dense and smooth rubber. Overall the cable feels very sturdy, though it looks quite thin. I would say that the cable is very much like the Xiaomi Pistons 2.0.
This is where I go on to say, “WHY U NO REMOTE???” I really do think that the Titans would be THAT much better if it had a mic and remote for mobile phones. We live in the 21 ^st  century people!!!
The jack is a very nice machined aluminium cylinder which feels amazing in the hand. The strain relief looks very sturdy and overkill, but that’s very welcomed in my books. The jack has a unique serial number on it, which is also a very nice touch.
The Y-splitter is also a cylinder and looks very much like the jack housing that’s a smaller diameter. It sports the Dunu Titan 1 logo. Bottom of the spitter is a smallish strain relief and above is an indent where the neck cinch fits perfectly inside. My only gripe with this is that the neck cinch moves freely up and down. It would’ve been nicer if the connection here was either a slight interference fit or a twist lock of some sort. Of course, nothing is 100% perfect.
 
 

Isolation

There is none! Moving on…
 
But serious, the Titans are the epitome of open design IEMs. They leak everything out and let all the sound in. So much so that my co-worker can tell me exactly what song I’m listening and which part of the song I’m up to, and he sits about 8-9m (26-27 feet) away from me. This isn’t always a downside because when I use earphones outside I dislike the fact the I cannot hear the traffic or what is going on around me and have to keep my volume down to do so. Not with the Titans, I can ramp the volume up to enjoyable levels and still hear everything from my surroundings. This would be perfect for cyclists and people who love to go for a jog or run.
 
 

Sound

I can describe the Titans sound signature with many words, some that come from the top of my head are: fun, balanced, engaging, spacious, coherent and full. The tonal balance is very interesting as its balance is not through the whole spectrum but at all the correct areas; having peaks in areas and not many dips that take away from the enjoyment and clarity of the music. For some tracks it sounds warm and on others it sounds cold, and on an occasion it’s a mixture of both. Detail retrieval is also very good and coupled with it's good staging and layering makes for some great critical listening.
 

Treble

The treble is indeed a little peaky and has track induced sibilance. It's not a sibilant earphone in itself but can get there with some pieces of music. I think this is inherited from the titanium driver. The Xiaomi Pistons 2.0 with its beryllium coated driver has this characteristic as well. But on the case of the Titan, the peakiness is not located in one area of the mid/lower treble; it extends far and well up without getting too sibilant or metallic. Here be airiness and sparkle, and there is plenty of it. A very enjoyable listen indeed. The only issue I have with this is that it does get a little bit fatiguing after a couple of hours of non-stop listening.
 

Mids

Balance! The Titans do seem to have a little bit of a boost in the mids, and it’s very welcomed. It’s accompanied by both treble and mid/upper bass to give you a very natural vocal and acoustic experience. There is still a vocal track that I need to find that sounds bad with the Titans. Male vocals are full, clear and alive, and female vocals shine and sing.
 

Bass

It is a little elevated in the mid bass region, but not a lot, and it doesn’t leak or overwhelm the mids at all. It’s not linear but is more balanced then most fun sounding IEMs. It extends quite low and stays impactful and coherent with good speed.
 

Soundstage & Imaging

It’s like listening to a concert in your head. The imaging is very accurate and has lots of layering to boot. Coupled with the above average soundstage width and depth, it evokes some really immersive listening. It’s not as wide or deep as the Havi B3 Pro 1 but that’s actually a good thing; the Havi being a little distant at times makes the listening laid back and in the background, but the Titans make it a “here and now” kind of “party in your head” type of listening. It makes you want to put your hands up, stand up and join the party. Yes, it’s like that.

Thanks to Mr. Tyll Hertsens for measuring these wonderful headphones!
 

 
You can see that there is a dip in the 5k region and it peaks back up to the 7k and drops back down to and past 10k. To me this is quite surprising because I find the L2 to be quite a bright headphone. The dip in the 5k region means that there is little sibilance. The elevated bass region plays well with what I expect for an open back headphone to keep the bass adequate. And the mids are flatter that what I perceived in my listening.

 

Packaging

The Fidelios come in a pretty big black box with quite a lot going on on it. A bunch of contrasting colours come together to give out a huge presentation which is elegant and inviting, simple and technical. All the relevant information is there on the box. The technology which is put into the headphone is written in 8 different languages. Even on the inside of the box there is some kind of safety information I've not seen before on any headphone packaging. 
 

Accessories

 
In the box you'll find:

1. The headphones (obviously)
2. A cable (I suspect it comes with 2 cables one with and one without remote).
3. A very nice felt (suede like material) lined with a polyester inner for which I can only guess is for weather proofing.
4. A 3.5mm to 6.3mm adapter.

 
 

Design & Comfort

If I was to describe the Fidelio L2 with only one word, that word would be “Stunning”! [size=inherit]The L2 is probably one of the best looking headphones I’ve ever had the pleasure to get my hands on.[/size]
First thing that grabs your eyes is that beautiful red stitching on the headband. The headphone is a wonderful combination of brown, red, charcoal and black. As you look on, you realise what an absolutely brilliant idea was it to give those subtle yet eye-catching red accents. Superb!
The headphone is made from a variety of materials which all look and feel premium in every sense. The red stitching holds together the supple headband covering which is made from brown leather (or faux leather). From what I can gather, the headband is made from aluminium and the cups are plastic. Every piece that goes into it looks like it was made precisely and with purpose. Back of the cups has a mesh grille which I can just guess is made from stainless steel.
The earpads are a bit of a bummer. Don’t get me wrong. They’re soft and comfortable, but they’re not removable. I just wish this wasn’t the case. For me, I feel like a bigger size of earpads would do wonders for this headphone, but this is a personal preference.
[size=inherit]Clamping force is also quite loose on this headphone for my small head which also plays into why I dislike the earpads. If it had a little tighter hold the pads wouldn’t be such a downer for me.[/size]
Cable is removable and seems to have a proprietary style of retaining the connector. I thank Philips for not going with another crazy plug system. It’s a standard TRS 3.5mm (1/8in) connector. The female jack is a little close to the flange so if you wanted to use a custom cable it would need to be a small diameter jacket/cover. I was unable to use none of my custom cables on it for this reason.
The cable provided is a paracord sheathed 3.5mm TRS to 3.5mm TRS jack. It’s soft and flexible and seems to be very tangle resistant. It’s quite thick and looks like it will last a long time. The cable has little to no mechanical noise or microphonics. I’ve read that it should also come with an in-line mic cable, but was not provided with the tour unit.
 
 

Isolation

I found that these have a weird open design. I have 3 kids which are not very quiet at all, and they give me a very good indicator on how good isolation is on any particular headphone. I have found that whilst the L2s leak quite a bit of sound out they don't let a lot of noise in. Making them quite a good headphone for home use while private listening, watching movies and gaming when there are no other people you can annoy, but have quite a bit of ambient noise from, say, construction sites and other noise pollutants.
 

Sound

It's pretty hard to describe how brilliant this headphone sounds. It is a very balanced sound with a lot of layering going on. It extends quite well into both treble and bass and seems to be very coherent throughout the whole spectrum. It has a very natural timber for acoustic and electronic music. And to put the icing on the cake, it scales extremely well with gear; give it more juice and it'll sound better and better every time. I was thoroughly impressed with this headphone, and it doesn't cease to put a smile on my face ever time I plop it on my noggin.
 

Soundstage & Imaging

The soundstage of this headphone is actually quite intimate and is slightly above average. But where this intimate soundstage shines is coupled with the excellent imaging. The imaging has really excellent depth and height. It layers very well, giving you a very realistic listening experience, as if the band is playing a few feet in front of you. There is good air and separation between instruments. I[size=inherit]t's very satisfying indeed![/size]
 

Treble

The treble is probably the best aspect of this headphone. It's crisp and clear, it extends well and feels quite linear. Maybe sometimes sound a tiny bit dry and blunted. But very smooth, natural and enjoyable. The treble is very coherent, so much so that I found that this is probably the best headphone for listening to trance music where there is a lot of synths and female vocals trying to fight for the front of the stage, almost always sounding congested, but not on these headphone. The layering is done so well that everything has it's own place.
 

Mids

Mids are perfect on this headphone. Never sounding dry, forward or recessed. I found that the L2 did extremely well with both female and male vocals giving them the timber they both deserve. Acoustic guitars sound very natural. Everything meshes very well together with great synergy and harmony.
 

Bass

The bass is amazingly balanced with good kick and rubble when called upon. It's not elevated but it's warm, tight and fast. Super natural. Bass guitars roll through the notes flawlessly and the bass kick is punchy and fast on decay. 
 

A quick comparison to the Takstar Pro 80

 
The Takstar Pro 80 is my baseline comparison headphone I compare ALL headphone and IEMs I audition. Only for the fact that it punches WAY above it's price range. Only costing ~$70 + $15 for the HM5 pads, I've seen them put $200+ headphones to shame.
 
The L2 definitely sounds like the more smoother and more neutral listen. It has an overall fuller and warmer presentation. It also seems a little more mid forward with more layering going on. Bass seems more mid bass oriented. 
 
The Takstar Pro 80 seems to be a flatter slightly brighter more metallic sounding headphone. The Pro 80 surprisingly sounds airier with a wider soundstage. Pro 80 sounds a little dryer in the mids. It has noticeable more kick in the bass being more sub-base orientated.

The HUM Pervasion as a Android Device The HUM Pervasion is in quite a good place. There are not a lot of Android power high fidelity digital audio players on the market. What this means is that HUM has a lot of power available in their grasp to utilise. Android, being an open-source platform, is capable of being anything that the designer chooses it to be, as long as it is set-up properly and as intended. I'm not convinced that HUM have done this correctly, and I'll explain why.   The hardware chosen is OK and is not really the issue. My biggest gripe here is the version of Android chosen. Android only gets better and more stable with every iteration. One of the biggest aspects of the newer versions of Android is the increasing support for external DACs. A limitation on the Android audio engine is that it is only capable of 48/16, and introducing the ability to use external DACs makes your Android device capable of all the formats the your DAC can play. This particular version does not seem to support any USB OTG devices at all, which is a huge bummer in my books. This feels like a huge opportunity missed. My other gripe is that the chosen ROM is not a community built one, like CyanogenMod. While I understand that there may have been method in the madness, I do still think it would've been wiser to go with an AOSP base ROM and cherry pick your own features for customisation and hardware/software tweaks, for example: hold volume keys down to skip tracks.  All these I mentioned can be fixed with a simple ROM flash, and I do hope that HUM hears my call and does just that. Because, in my humble opinion, if this does happen, it will make this player a force to be reckoned with.   Now continuing with the review...   Playing around with the HUM Pervasion I noticed that this is probably one the smoothest Jelly Bean 4.2.2 experiences I've encountered. It is after all a fully stripped down version of Android. It is slightly modified but mostly just stock Jelly Bean.  It is quite a joy to play with being an Android user myself.    The apps that come preinstalled are: Chrome (internet browser), Explorer (file browser), Gallery, Gmail, Play Music, Play Store, Settings & Video. It's really as bare bones as you'll ever get.   Recommended Apps The apps I would recommend for playing music are as follows: HibyMusic, PowerAmp and USB Audio Player PRO. All are great music apps and are available on the Play Store. HibyMusic however was not available to download from the Play Store for the Pervasion, so what I did to get it installed was get the HibyMusic apk file from my rooted MotoG and transferred it across to the Pervasion and installed it manually from the Explorer app. Everything worked like a charm from there.   You may also play all you favourite games on this device. Don't expect it to run anything graphics intensive though. It'll run all you Candy Crush and Flappy Birds to your hearts content.
Design & Build   The HUM Pervasion is quite a chunky device. Of course this is only compared to a normal Android phone. Compared to any other Hi-Rez DAP on the market it doesn't seem that big at all. Measuring at 66.6x118x13.8mm it reminds me a lot like my old Motorola Atrix (which I actually have on hand - see photos). This is the size that Android phones used to be a few years ago before they began to stretch to wider, longer and skinnier proportions. Everything about this device screams to me "Classic Android Phone", and this is something I actually like. It's what made me fall in love with Android after all the year of being a Nokia user.    The HUM Pervasion is mostly made of glass (front) and aluminium (rear). The rare cover is a solid chunk on aluminium which wraps around the player on all sides. It looks and feels like it will last a long, long time. On top you get a power button and the MicroUSB plug which actually feel very sturdy when plugged in. Left you get the volume rocker. Right is simply the microSD card slot which can hold up to 128GB. And the bottom is where the magic happens. You get a line-out, an ALPS analogue volume knob and the headphone out.   It's a very unique that feature to have both a digital and analogue volume control. But it's welcomed here.   Screen I'm not sure if the screen is made from Corning Gorilla glass and I'm surely not going to test it to find out. Let's just say that I didn't hesitate to apply a screen protector on the unit when I received it. The resolution is 800x480 which to me is still adequate as it's always been. The screen does have some reflection and is not the most ideal for use in the sun.   Battery Battery life is quoted to be 6 hours and that is about right with what I've experienced. For me this is not an issue but for those who do a lot of commuting may know the frustration of a dying battery. It does charge quite slowly, but I found that it helps to use a better charger, something that pushes more than 1 amp.   EMI (Electromagnetic Interference) When using the WiFi you do get considerably a lot of EMI. It's noticeable at all volumes, and it's very annoying! DO NOT USE WIFI WHILE LISTENING!    WiFi WiFi strength is weak and the connection is somewhat temperamental when not in the same room as the router. Otherwise it work as intended.    Bluetooth Bluetooth works as intended when the screen is turned off. The second you turn the screen on the sound starts to stutter. I think that this may be another software issue with the old version of Android. I could be wrong, of course.
How does it Sound? The HUM Pervasion does not disappoint in the sound department. Boy does it sound good! It is a very musical player, extending both treble and bass, making everything you listen to alive and fun. Most of my listening is done in the office at work where I need to have the music in the background. I could not use this player at work all the time. The reason being, is that I could not concentrate on my work. It made me want to jump up and dance, reach for that volume knob and turn it a little up. Most of the time spent the first time I listened to the Pervasion was me flicking through my favourite tracks and listening to them like I haven't heard them in 10 years. It was definitely quite an experience. "The player sounds very good" is where I'm going with this, if you haven't got that yet.     Some Comparisons *Comparisons using only the opening of Eagles - Hotel California on V1 MP3 converted down from 96/24 vinyl rip using latest LAME.exe through the Havi B3 Pro 1. **Switching between sources using my DIY AB switch (pink thing in the photos). *** Volume matching is done by ear, so not so accurate.   xDuoo X2 VS HUM Pervasion HUM Pervasion is instantly noticeable to have a more cleaner delivery. Bass is effortless with good speed. Electric guitar is airy and placed correctly on the stage. Cymbals are metallic and placed correctly to the side, slightly behind.  xDuoo X2 has noticeably better soundstage and imaging; being slight wider and much deeper. Cymbal are further in the back, but aren't as natural sounding; smoother not as tinny or metallic. The sound isn't as refined as the HUM pervasion and the X2 is running out of headroom in terms of power. This track has a LOT of dynamic range and I had the X2 on 27/40 volume and the HUM maybe a quarter in.   HUM Pervasion wins. But both sound great. Fun, forward and engaging.   FiiO X1 VS HUM Pervasion X1 runs out of steam fast here. 90/100 volume. Treble is a tonne smoother & slower with the X1. Bass kick is somewhat hollow compared to the HUM Pervasion and not as punchy. Soundstage narrower. A very laid back sound here on the X1.  HUM Pervasion is a much fuller & warmer sound than the X1. Bass guitar flows all through the note held, unlike the X1 where the note flows but feels loose. Treble here is much more sparkly and sharp. The cymbals have more bite and electric guitars has a much more natural timber.   HUM Pervasion wins hands down. X1 is a more comfortable listen though. I could listen to it all day long. Pervasion might get a little fatiguing at the same volume levels. Though, the HUM Pervasion is a much more rewarding listen.   Audio-gd NFB-15.32 VS HUM Pervasion This did not go down how I expected it to. AB'ing between the 2 actually gave very, very similar results. They have the same amount of warmth and both are quite forward. The NFB-15 definitely has more extension in the treble. The electric guitar and cymbals sounded brighter, more real, and the cymbals seemed to ring slightly longer. Mids sound a tiny bit more refined here. Soundstage is slightly wider and imaging is slightly more accurate. Everything else is pretty much on par.   I'd give this one to the NFB-15 but the HUM Pervasion was not far behind. If I wanted a portable DAP that sounds like the NFB-15, then this would be the way to go.

A little about the thinksound rain2: The thinksound rain2 has a sustainable approach to the market. This is visible throughout. Everything here is designed to be made from eco-friendly materials and you can definitely see this with the packaging, and chosen materials. Not sure about the rest of it.      Specifications (taken from the thinksound website)   Wooden housing for crisp, accurate music reproduction Frequency Response: 18 Hz – 20 kHz Sensitivity: 96 ±3 dB @ 1KHz 1mW Impedance: 16 ohms 45˚angled 3.5mm gold plated stereo plug for increased sound clarity Driver Size: Acoustically enhanced 8mm driver Weight (Approximate): 9.5g Ultra-lightweight design Kevlar-reinforced, tangle-resistant 4 foot long cable Passive Noise Isolation minimizes ambient sounds Sweat-resistant design, perfect for the gym

Packaging and Accessories Packaging looks cheap. It's a simple white outer box, nothing special, it has some of the information about the rain2 on the back. The inner carton is made from cut cardboard, looks like it was hand cut too, as it's not the neatest job but it's a nice touch.  Including in the box is the earphones (obviously), 4 pairs of black silicone tips, a shirt clip and a cotton carry sack. Nothing more, nothing less. I do think that for the price tag there could be some extra tips to choose from. I personally think that it would do with a set of wide bore tips.   Build quality The build is actually quite nice. It's light and made from good materials. The wood is lovely and meshes well with the dark smoky steel front portion of the body. The strain reliefs and the cable is made from a nice, supple rubber which is very tangle resistant. The jack terminates at the 45 degree 3.5mm connector which is gold plated.  Presentation and build quality is something that is done very right here.   Isolation is average as this is a ported design. There is one single port on the back of the housing. You do get some mechanical cable noise when wearing it cable down.   I do get some pretty bad driver flex with all the ear tips I've tried. Seems like something one will need to get used to with these.

Sound

I used the rain2 with the following gear: FiiO E17, FiiO X1, xDuoo X2, HUM Pervasion, Audio-gd NFB-15.32 and straight from my Moto G XT1033. Using them for various genres and watching videos on YouTube.
 
The box states that these earphones are "High definition... a smooth sound signature." Which is a statement I cannot agree on. The sound signature is my least favourite aspect here.
The thinksound rain2 is a very dark earphone. The best word I can describe them with is "Brash".
Soundstage is actually quite good and imaging is above par.
 

Bass

The bass is very elevated. It is the most pronounced and overwhelming part of the signature. It resonates through the whole spectrum and on some (and mostly everything I listened to) tracks and it distorts quite a bit. It extends quite low and is very deep, visceral and is bloated and muddy.
 

Mids

Male vocals are brash indeed. Some sound like there is an eco in the background and every song I've noticed sounds like it is recorded in a large and empty room. The bass completely overwhelms everything that has even a little bit of mid or upper bass in it and amplifies it quite dramatically. It's something I really did not enjoy all that much.
 

Treble

This is an aspect that is actually really good on the rain2. It's not recessed, it's not the most refined treble you'll hear, but it's quite smooth and coherent and keeps all the major elements in vocals and percussions audible and this is something that balances out the sound quite well. This could be a saviour for some people. Especially those who do love a lot of bass and clarity in one package.

Conclusion

While I do applaud thinksound for creating sustainable and eco-friendly products, I don't think that they have gotten the sound signature right. Of course this is a personal preference and I'm sure that some people will love the way they sound. But for me, I didn't enjoy them very much, unfortunately.
 
Cheers!

[size=24.5699996948242px]Packaging[/size] The box is hard cardboard and has a great thought out colour scheme. Very contrasting with the lime green and charcoal, with a little bit of a carbon fibre touch that has the Fidue logo within it (which I think maybe a little bit too much). The tones and contrast go great together to attract the eye and get you to come closer and read the box.  Writing on the box just has the name and specs on it in English, Chinese(?), and German.    Inside the box you find most of the earphones tucked neatly into the carry case and the ear pieces sitting snug in pre cut nooks cut into a felt pad sitting on top of the foam guts of the box. Great stuff! I've not seen anything like this before. It kind of reminds me of when you buy jewelry or maybe a boutique watch.    Accessories You get a nice looking black carry case witch is oblong in shape. It's got a nice soft touch and has the Fidue logo impressed into the top of it. Inside you get a felt backing and a pocket to store the spare ear tip or whatnot. You get a Velcro hook/loop strip to tie off the cable for easy storage inside the case. The felt backing of the case lets you then just stick the earphone in the case so it doesn't fall out when you opening the case.   In terms of ear tip you get the following:   3 pairs of Silicone tips (S/M/L) 2 pairs of double flange silicone tips 1 pair of foam tips   The ones that I like the best were the small double flange tips. Which, if fact, are now my favourite and have been my new go to ear tips for all my IEMs.   Comfort I have to straight out say that these are by far the most comfortable IEMs I've used. They're super light and have this great malleable steel insert in the ear hook which allows you to shape them to your ears. The result is extraordinary! The perfect term for it, and I quote, "Set and forget" (thanks to @H20Fidelity for using this term, it's perfect). I can go for a sprint with these on and would not even notice that they are in my ears, and they are in so well that they will not fall out. And believe me I've done this. Top marks for this.   Isolation Isolation is great. I have 3 kids who just love to annoy me when I'm listening to music. Needless to say that I can thoroughly enjoy my music by drowning out the screams and cries of a needy child. Good marks for this as well!   Design and Build The build quality looks a bit cheap, but because they are so light, unless  you step on them with your foot they could not break if you dropped them. In addition, it has great strain relief and the cable [size=inherit]quality feels great. [/size]   The design of them is actually quite interesting. The main part of the housing is black, lightly see through plastic. This means that if you shine light through it you can actually see inside the chamber. The back of the housing is solid plastic, sporting the Fidue logo, which is lofted into a triangular shape of the strain relief, which extended into the earhooks. It a very nice transition. The earhook extending from the strain relief gives you the impression that the cable will last much long in that region.   The Y split and jack are made of machined aluminium with round burrs for extra grip. You'll find the Fidue logo on them as well. Strain relief on both is thick durable rubber.   You also get a neck cinch, which is a welcome addition, but my quarrel is  that it is way too tight on the cable and is quite hard to position. I tend to leave it alone in fear of stripping the cable.   Sound The Fidue A71 is a dual chamber, dual driver IEM which means that each driver has it's own chamber to push air from. I'm no expert on this but what I would gather from this information is that the sound waves would not cross paths until it hits your ear. Correct me if I'm wrong, though. My initial impression was "Mind rattling", but as my ears got uses to the sound the bass got less "boom = ouch" to a rumble that gave me a chill down my spine.    Overall the the Fidue A71 sounds good. It's bass orientated without having any recesses that I can hear. Its very warm but has enough treble to stay detailed for the most part. With the mid bass bloat you get a sense of bloominess in the air which is quite sweet in some tracks. It has a great soundstage. Way above par to what you normally get with an IEM. It's wide and deep, though the bass makes it quite an intimate listen as it takes away from the airiness.   Bass The bass extends well into [size=inherit]the sub-bass of around 30Hz maybe even a little lower. But it has a huge mid bass hump which bloats quite a bit. It bleeds into the lower and mid mids. The bass punch is big and visceral. I quite enjoy it for modern music where you don't need to hear the fine detail, you just listen and enjoy. But when you want to listen to something complex the bass puts a veil over some of the finer details you would normally enjoy. And frankly, to my ears, these earphone are BASS CANNONS![/size]   Mids The mids are very rich and warm. Acoustic guitars sound very real like they're in front of you. Male vocals are somewhat let down by the bass. They sound deep and in some songs I found that they are getting downed out by the bass. This is of course only when there is a mid bass orientated bass line present.   Treble The treble extends very well. It has no sibilance and doesn't really have any peaks or dips which makes the sound unnatural or metallic. There is a tiny bit of emphasis on the "SSS" sounds, which I actually like. Really sounds great with female vocals when they whisper into the mic. Sparkle is present but not as much as I would've hoped for. The sense of air and space is hindered by the bass making the sensation of air more like a bloom instead. ​	​	[size=24.5699996948242px] [/size] [size=24.5699996948242px] [/size] [size=24.5699996948242px] [/size] [size=24.5699996948242px] [/size] [size=24.5699996948242px] [/size]         ​
