Canpur Performance Series CP622B

Canpur CP622B Review

Disclaimer

Canpur CP622B has been provided to me as a part of review tour managed by Audio Geek, India. I have no affiliations with Canpur Audio or related to them in any way. All my impressions are purely based on my listening capabilities and gears used. I thank Audio Geek, India for providing my this IEM for audition.

About



Canpur is a Netherlands based company, established in the year 2019. CP622B is their present flagship model, which is what in my hands at present. CP622B’s driver configuration goes as 6 balanced armature drivers, 2 electrostatic drives and 2 bone conduction drivers. Rated impedance is 10 ohm at 1khz and sensitivity at 100db at 1khz. It’s relatively easier to drive IEM, but, as with any TOTL IEM, do scale with better equipment. It is priced at 3,499 USD.



Sources Used

I had used my DAP, iBasso DX260, on HG for the review purposes. Tips used were Divinus Velvet Wide and two upgrade cables in Verus Lavender 6 and Effect Audio Fusion 1.

Sound Impressions

Right of the box, CP622B sounds very technical with very good performance all through the spectrum, with no dips. Bass is very good overall. Sub bass rumble is very good, though it doesn’t go deeper as RN6, but still very good on its own. Mid bass has very good slam too. Overall, a very good bass performance. As said, I would have liked if sub bass goes even deeper than what it is.

Mids are clean, natural and detailed. Bass doesn’t overpower mids. Vocals have good note thickness, making them natural. Female vocals have very good energy to them and extend very well. Mids lack in engagement slightly, and lower mids are slightly recessed.

Technicalities are excellent. Soundstage has very good width and depth. Instrument separation is excellent with very good space between instruments. Imaging is very precise. Cymbals are crisp. Treble has very good extensions and is sparkly and airy. Treble isn’t fatiguing while having excellent extensions. Details retrieval capabilities are top notch. It’s a very resolving IEM.

Even though the stock cable, provided by Eletech Audio is an excellent one, CP622B do need a cable swap to finetune it a little and to get an overall improvement. I have two upgrade cables with me, Verus Audio Lavender 6 cable and the other being Effect Audio Fusion 1 cable.

w/ Verus Audio Lavender 6 Cable



Verus Audio Lavender 6 cable is made of bespoke 7N OCC gold plated copper, long crystal gold plated silver, OFC silver plated copper in 24.6 AWG core, 24.3 AWG shield in a flexible insulation, retailing at 635 USD.

Swapping stock cable with the Lavender 6 cable, indeed brought few welcome changes, bass now reaches deeper than what it does on stock. Mids sound slightly thicker and now sound more energetic and engaging. Female vocals sound natural, engaging and energetic. Soundstage too found an improvement, CP622B now sounds slightly wider and deeper than the stock cable. Details are now presented with more clarity. Treble has excellent extensions and sound more spacious and engaging. Dynamics and resolution too improved upon the stock. CP622B really shines with this cable with an all-round improvement in all departments.

w/ Effect Audio Fusion 1 Cable

Effect Audio Fusion 1 cable is made of selected premium UPOCC material gold plated silver litz, pure silver litz and pure copper litz hybrid, proprietary tri-strata layering fusion mix. This cable retails at 999 USD.



EA Fusion 1 cable further enhances CP622B in all areas. Bass now has better control and texture with deeper reach. Mids have better presentation for me so far when paired with Fusion 1 cable. Mids have better clarity, texture and definition. Slightly U-shaped, but excellent mids overall with Fusion 1. Male vocals are natural and clean. Female vocals have excellent sparkle while being natural. Treble, is very sparkly and energetic with very good air. Treble has excellent details. Soundstage has excellent width and depth, with precise imaging and excellent instrument separation. Technicalities are top notch, with excellent detail retrieval capabilities and dynamic range. Cymbals are crisp and clear. I really liked how this pair sounds, I recommend this cable for CP622B, as it elevates the IEM in an excellent way.

With stock cable and Verus Audio Lavender 6, I found mids to lack resolution by a little, but Effect Audio Fusion 1 cable changed everything and finally CP622B performed at its best.

Comparison

With FiR Audio Radon 6

Radon 6 is also a flagship level offering from FiR Audio, which I happen to own and love it. RN6 utilizes 1 DD, 4 BA and 1 EST drivers. On direct comparison with CP622B, I found both to be highly resolving and technical sets, differing in few areas. RN6’s bass has deeper reach and is more visceral of the two. RN6 also has slightly forward and engaging mids compared to CP622B and even in upper mids and treble, RN6 has more bite and sparkle of the two. CP622B, though has wider stage and equal depth. Both IEMs perform excellently in technicalities, dynamics, imaging and instrument separation, and I found both on par. Detail retrieval is slightly better on CP622B. RN6, with its kinetic bass, wins you over in bass region, that doesn’t mean CP622B lacks in it, but it doesn’t go as deep as RN6 or as visceral as RN6. Can say both sets as complementary sets.

Verdict

Canpur CP622B is an excellent IEM, with great technicalities and resolution. It punches competitively for its asking price. It has punchy bass, slightly recessed and yet natural and resolving mids, energetic and yet non-fatiguing treble. It performs excellent all through the spectrum. For me, I wish its mids were little forward, which can be negated with a quick cable swap. Effect Audio Fusion 1 cable did the trick for me.

Disclaimer:
I'd like to thank AudioGeek for including me in the tour of this wonderful IEM. Canpur is a Boutique IEM brand from the Netherlands. This is the first time I'm trying something from them, and I must say that I'm mighty impressed by what the CP622b has to offer.

Introduction:
Given how much they've packed in on each side, the earpieces are huge. I haven't come across another IEM with such huge earpieces, barring ofcourse, the Audeze iSine and LCD series earphones. The CP622b packs 6 BAs, 2 ESTs and 2 BCDs on each side. That's a whopping 10 drivers per side with a 5-way crossover and their custom micro-inverter tube design. I personally had no issues in terms of fit or seal with these earpieces, but smaller ears are likely to struggle with the fit. They're not heavy per se, thanks to the acrylic shells. The faceplate design is quite elegant and doesn't appear to be too flashy.



The IEM comes with a bespoke 2 pin 7N 24 AWG OCC cable with 4.4mm BAL termination, which has been cryogenically treated and infused with Kevlar by Eletech. Hence, it is superior in terms of both sound and build quality, and, as one would expect, free of microphonics. The IEM comes with 2 sets of silicon eartips, grey and white. Of these 2, I preferred listening to the IEM with the white tips, but overall, I liked them best with SpinFit Omni.



Sound Quality:
The Canpur 622b is a basshead's dream. There is crazy rumble thanks to the 2 BCDs on each side and the slams are powerful. It has more presence in the sub bass region than the mid bass and it delivers excellence in terms of both bass quality and quantity.



The mids although a tad bit recessed in terms of presentation, sound organic and natural. There is good note weight and the IEM is capable of picking up the most subtle of nuances in the vocals, thereby, conveying the emotion in the artists' vocals beautifully.

The treble region again sounds natural. Treble is crisp and detailed but not too sharp or piercing, which is a good thing. There is a good amount of air, thus giving the sound a sense of spaciousness. Overall, the treble is inline with the rest of the frequencies, giving the IEM a neutral - warmish tonality with great amount of detail.



Technicalities:
The CP622b delivers holographic sound with a soundstage that is wide and tall. The layering and resolution is excellent with precise imaging and the ability to pick up the finest of details in a track. Technically this is one of the best IEMs I've heard till date.

Conclusion:
The CP622b is an absolute banger of an IEM that can truly be the endgame for an audiophile. The shells could be a problem for smaller ears, but once you're past that and the price barrier, this is a blissful in ear experience and the path to audio nirvana. Pair it with a capable source and it will mesmerise you with it's killer tonality and breath taking detail.

This is the first installment of a 3-part series, reviewing the two IEM’s with the most hype in the industry, at the $3k mark. I did a previous review of the Grand Maestro (GM) a few months back, also here on Headfi. https://www.head-fi.org/showcase/fatfreq-grand-maestro.26521/reviews

I own both of these sets. My opinions are my own.

At CanJam NYC 2024 I had the opportunity to try several TOTL IEM’s, including the Storm, Fei Wan, GM and the CP622B (CP). The GM took my breath away and still does, but I felt like I hadn’t had enough time with the CP and it needed to be revisited.

MusicTeck (https://shop.musicteck.com/)is only a 25 minute drive from my house, making it convenient to schedule some time with Andrew and his team for a good listening session. Those who’ve been following my DucBloke PEQ series on several Facebook pages, I’m all about squeezing the absolute most out of every IEM, through the strategic implementation of multiple PEQ settings to “FIND THE SWEET SPOT”. In preparation for the listening session I made some custom PEQ settings, albeit not from the actual frequency response of the samples I’d be listening to, but close enough to get a good idea of where I might be able to take one of these little gems if it came home with me.

What I Listened To:

I started with the Verdandi, having a unique driver configuration with bone conduction, I wanted to hear how Kinera was implementing this tech in a TOTL IEM. It was very bright, but the PEQ setting tamed that down and made the Verdandi a much better IEM.

I then moved to the Fei Wan, a set I have a great deal of respect for. The texture is second to none and I wanted to see if my PEQ project could also impact this $4k beast. The results were equally as elevated as the Verdandi and confirmed by Leo from MusicTeck.

I then moved to the Traillii, a $6k IEM that also has incredible texture and tonality. I wasn’t expecting to be able to improve this set by much, but again confirmed by Leo, the listening experience was elevated significantly through strategic PEQ application.

I then focused my attention on the CP622B. An IEM that is being hyped as the G.O.A.T. Initial thoughts when listening for the second time…hmmm this isn’t as good as the GM, but it’s very good. Where the GM excels (Bass) the CP seemed to be lacking and vise versa. I had also prepared a set of PEQ settings based on my process and applied it in an A/B test. WOW, ok now you’ve come alive. My jaw just about hit the ground. I handed the set to Leo to confirm in a blind A/B match up and he was equally impressed with the improvements made to “The Best IEM In The World”. Going in I know I wouldn’t be laying out the $$$ if I didn’t have a good idea of just how impactful the PEQ project would be to TOTL IEM’s and the CP in specifically. Andrew here’s my card, this little beauty is coming home with me!



Before diving into heavy PEQ analysis and adjustment, I wanted to “Raw
Dog” this set against the GM. Get a good baseline for what each of their strengths and weakness are “Out-of-the-Box”. Fully knowing this would be a very Hot and Contentious topic, whereby I’d have to be the owner of both sets to really deliver a good non-bios opinion.

My Design of Experiment (DoE) would involve listening to 40 different songs from different artists and genre’s (see the images). Evaluating 17 different parameters for each track, on a scale of 1-10 and working at a final score for each song, plus an over all average for each parameter and final score for the 2 challengers for the title of G.O.A.T.

I had already ranked the GM at a 9.6/10 in my previous review months back and I was wondering if I’d land close to this in a larger head to head competition, but the results proved I was very very close to my initial impressions.






Bass Region: The GM takes this category. Should be noted I love my Bass and used the Black Noah module, with the tuning switch to the back position for all testing. The rumble in the Sub-Bass from the GM is second only to the FATFreq Scarlet Mini, but the GM has the advantage of doing everything else very well. The CP was no slouch in Bass, but lacked in the Sub-Bass rumble and Bass feel, despite having Bone Conduction. See Image




Mids and Treble: This is where CP started to show its chops with better clarity in the lower mids, all the way through to the upper treble region, with better treble extension. See Image




Sound Stage, Detail, Masking, Note Weight and Slam: All went to the GM, with it’s ability to isolate instruments, second to none and its ability to deliver the Bass punch/slam feel, also giving better note weight.


Timbre, Tonality and Texture: All went to the CP622B. Whereby, the strength of the more accurate mids and treble shows through to better tonality, timbre/color and the Texture of the notes in this region make it a better listening experience for these attributes.


Worth noting that these two TOTL IEMs traded blows back and forth for each song, with the Grand Maestro winning by narrow margins on 24/40 tracks, with 5 ties and the CP622B winning on 11/40 tracks. This was mostly due to the Sub-Bass and Bass feel of the GM. The overall score of the GM is 9.68/10 (very much inline with my original review) and the CP at 9.54/10. Making for a Grand Maestro Victory by 0.14/10. This was a photo finish.

Fit, form and function: The CP takes this category. It’s a smaller IEM (still pretty big) than the GM, which is massive. This allows for a much closer Pinna fit.



Looks, Quality and Accessories: Both are pretty good, but the Grand Maestro wins in all of these categories, with the stunning shell design, the beautiful high end watch type box and the 8 strand gold plated silver cable, it stands out in the crowd. That being said, the CP’s included stand, leather case, Eletech Black cable and tip selection are very good quality. Plus the Leather storage box makes for a TOTL look and feel.


What’s Next: As I said, this is the first installment in a 3 part series. Next will be to apply PEQ to the CP and see just how much better I can make each of the 17 parameters measured. Then to compare both in a rematch, with applied optimized PEQ settings and see how much they both improve and which one truly deserves to be called the G.O.A.T.

Disclaimer: I received no incentive for writing this review and received NO discount on either set for doing so. The links before are to FATfreq and Canpur, plus MusicTeck, where Andrew is just a really good guy and easy to do business with.

I also know Ben from FATfreq out of Singapore. Used to live there and Ben and his team are the best in the industry to work with.

Canpur CP622B – brief sound impressions, by Sameer Tangri

Introduction:
I received the Canpur Canpur SEA Canpur CP622B as a part of its India tour conducted by Audio Geek "Brother_Hood of Audiophiles" and Sandeep Agarwal. The CP622B is a flagship IEM with a 6BA+2EST+2BC driver configuration. At $ 3,499.00 this is amongst the most expensive tier of IEMs. Fortunately, it sounds like that! Read on.

A little about me:
I prefer a balanced to warm sound for enjoying my music. I own sets like the 64 Audio Trio, Final A8000, and Thieaudio Monarch MKII. I dislike any one frequency overpowering or dominating all others, be it bass, mids, or the treble. Occasionally, I do also listen to reference/analytical sets with a flat sound signature. I very rarely prefer all-BA setups, no matter how high-end they are. Technicalities and capabilities aside, I always look for an IEM/HP that grabs my attention the moment it starts playing (trust me, IEMs/HPs that really connect with me always make me listen the moment they start playing). An IEM/HP should sound clear, fun, musical, melodious, draw me into the song, and most importantly make me feel the emotions! If a Rs. 1,500/- (USD 18) IEM does this, I buy it too (e.g., the 7HZ Salnotes Zero v1).


Design, build quality, fit, and comfort:
The CP622B is big! I thought that I was used to big chunky sets but boy was I mistaken. This is another level big and chunky. When lying down with the CP622B in my ears, it was not possible to look right or left as the IEM protrudes out so much that it hits the pillow. Also, initially I could feel its presence in my ears continuously and no matter how hard I tried, I couldn’t ignore the CP622B’s presence in my ears.
I got more used to it on the second day but still, it always felt like there was something in my ears. There’s no way around the size. The weight too is a middleweight. But coupled with its size, this middleweight IEM always made its presence felt.







Chain-1:
HiBy R8 --> Canpur CP622B’s stock cable (4.4 mm) --> Canpur CP622B --> Canpur CP622B’s stock ear tips (I found ‘S’ ear tips more comfortable, which are a size smaller than my usual ‘M’).

Test Playlist:
and other songs.


Brief impressions on the sound quality:
I shall simply explain the way I heard my songs through the Canpur CP622B. There are some IEMs that I think deserve this instead of the usual ‘Bass-Mids-Treble-Soundstage’ routine and it’s because they do something special with the sound.

1. Naina by Anand Bhaskar Collective- the clearest I've heard with every intrument and squeak heard easily; the bass hits with its quality, quantity, and delivery (especially from about the 4:02 mark); background singers are heard so nicely in some places. Towards the end of this song, it gets quite busy with a lot of shimmery and treble-oriented instruments playing. Here (based on my personal preferences) I did think that the sound was slightly more energetic than I preferred. I am sure EQ, tip-rolling, and cable-rolling would alter this as per preference. The sound is never uncomfortable or peaky or sibilant though.

2. Sapling by Foy Vance- The Canpur delivers this beautiful song with complete justice and more. The bass thudded and actually vibrated in my ear. It is here that I felt the BCD drivers making their presence felt. Vocals are so nicely presented that you cannot help but stop whatever you're doing and appreciate them!

3. Turn Me on by Norah Jones- Here too the bass thuds make their presence felt. I so enjoyed it! Norah Jones' voice sounds ethereal, and I heard the voice modulations in it in a different light over the CP622B.

4. Head In The Clouds by Hayd- It starts off slowly with an instrument or two accompanying the haunting vocals. Gradually, as the song progresses, more instruments make their presence felt. I couldn't help but marvel at how beautifully the CP622B brings everything together. The vocals are placed slightly forward (which I believe is what the artist intended intended) and make you listen to every word of the lyrics.

5. Aasman Rootha by Anurag Saikia- The moment this song starts off, the flute comes along hauntingly with the accompanying sounds of rain and thunder. The bass thuds and vibrates (once again! ). Vocals started and that was it. I was lost in the music till this song ended. Then I played it back again and forced myself to write my observations.

6. Half Of Forever by Henrik- this is one of my favorite songs. The CP622B had me bobbing my head, swaying my shoulders left and right, and hitting imaginary drums in the air.

7. Blaze Of Glory by Bon Jovi- I grew up listening to this artist and have bought tape after tape of the same album/s because I played them so much. And yet, when I heard this song on the Canpur, it made me hear the music in a way I'd never heard it before. The intro of this song sounds especially beautiful on this IEM. The way the drums played towards the end sounded on the Canpur is something I cannot describe. You gotta listen to it yesterday!

8. Radioactive by Imaging Dragons- Oh boy! The way the BCD drivers have the bass rumbling is something else. It’s the first time I have heard this song sound like this.







Chain-2:
HiBy R8 --> Headgear Audio Litsa Pure Silver 4w cable (4.4 mm) --> Canpur CP622B --> Canpur CP622B’s stock ear tips.
Headgear Audio cables are always very good in my experience. And I was once again happy with the synergy this cable showed with the CP622B.
With this cable, the overall sound immediately tightened up across all frequencies and became airier, faster, better separated, clearer, cleaner, and crispier than the stock cable. The increased clarity and cleaner sound were the most prominent and noticeable aspects.
I cannot say one cable is better than the other. Both offer their own flavor and style of sound delivery, and it would come down to individual preferences. I personally prefer the Headgear Audio cable due to the cleaner sound I got with it.


Conclusion:
Now here's the thing- I can go on and on with the praise but I think will either run out of words for framing my compliments or then start repeating myself (maybe I have already done that). It is mind-boggling really, the way the CP622B delivers sound and to sum it up I can say that this an exceptionally clean and reference sound and one that is equally musical and cohesive. It will keep you coming back for more! This is the ‘Business Class’ or even ‘First Class’ of the audio lounge we’re all a part of. That's really all I can say.
Tomorrow this set moves on to the next person in the tour queue and it is the first time ever that I am going to miss an IEM. I shall be back from First Class to Economy Class and it will take me some time to adjust to my real world. If this doesn’t say it, nothing will.

Review Of The Canpur CP622B​

Introduction​

Canpur is an electo-acoustic production firm that specializes in in-ear monitors. The brand was founded in 2019 in the Netherlands. This firm was founded by Mr. Hans JAPM Witjes, a professional band drummer since the 1980s with approximately 30 years of expertise in live performances and sound tuning. One of the most important factors that sparked this entire process was the development of low-cost equipment for professional musicians, vocalists, and sound engineers. The name Canpur is derived from "CAN PURE," which represents "resoration, purity, and auditory pleasure." They have a vast line up of IEMs ranging from 320 dollars to 4900 dollars, but they have only lately gained attention for their flagship product, the Canpur 622B. I was fortunate enough to get my hands on them for review, but first I'd want to clarify a few facts.

Disclaimer​

*This is a review unit, courtesy of Joseph Mou, Lanstar, Canpur SEA and Audio Geek Brother_hood of Audiophiles. All thanks to them for providing. And as I've said in all of my evaluations, the same is true for this one: all of the concepts I've expressed below are entirely my own, original ideas that haven't been influenced by anyone else. If interested, go to this link.
*I am not associated with the connection, and I receive no financial assistance from anyone.
*For the remainder of the review, I will refer to these IEMs as “622B.”
*I am using different Ear-tips for convenience and better versatility.
*Finally, I will only evaluate the 622B based on their performance, even though I will explain how it feels and seems physically and aesthetically.

Specification​

The 622B has a 10-driver arrangement that is a tri-brid setup consisting of 2 electrostats, 6 balanced armatures, and 2 bone conduction drivers paired with a 5-way crossover and employs in-house technology known as micro-inverter tube design. The shells are on the larger side and very nicely crafted. I believe the faceplate provides gradience with a rich and lovely appearance. The entire shell seems and feels quality and professional, however the larger size may be an issue for those with small ears, but with the correct eartips, the fit is doable. Personally, the fit and comfort were satisfactory, with the exception that I had to replace eartips to Divinus velvet eartips to achieve a decent seal. The cable included with these IEMs is from Electech, a firm that specializes in premium and luxury cables, and I believe it is a pretty decent cable with nice thickness, flexibility, and appearances that complement the IEMs. The cable is a 7N high purity single crystal copper cable with a two-pin connector on one end and a 4.4mm straight termination plug on the other. The additional accessories include a choice of eartips, a cleaning cloth, a cleaning brush, and a luxury leather casing that feels and looks authentic. According to the technical parameters, the impedance is 8.9 Ohms and the sensitivity is 103.8dB. The frequency response ranges from 20Hz to 70kHz.

Sound​

At first, I thought the 622B's tuning leaned toward neutral with sub bass bosst tuning, but after more time with it, I realized the sound is more mid-centric. The midrange is dominant, with significant expansion to the higher and lower frequencies. I don't own or have IEMs in this price bracket, but I've heard IEMs from manufacturers like 64 Audio, Vision Ears, Noble Audio, and others, but personally 622B offer the greatest sounding midrange I've heard. Of course, Trailli by Oriolus sounds far better in terms of resolution and expressiveness, but it costs twice as much as the 622. However, when it comes to the midrange, I feel both extensions lack prominence and forwardness. However, as a mid-centric sounding IEM, I believe it is the greatest IEM I've ever heard overall. Let's go further into the sound and discover more about it.

Treble​

For an IEM costing around $3000 USD, I believe that most people would prefer an all-rounder, which excels in all regions and brings the best of what the IEM has to offer. The 622B does the same, but in the upper extensions, it lacks forwardness or prominence in the mix. It is not mentioned, but I believe the 622B is tuned to provide the most authentic sound from the notes, with the treble set to be smooth and relaxed. However, I believe that the treble is sufficiently prominent to provide the desired balance in the mix; that is, due of the nice extension and airiness, the midrange does not seem closed or capped at any point. The upper treble provides for nice details that are well balanced, but they are not highly underlined when it comes to micro subtleties; anyone listening to them would not notice that sharpness or crispness in the mix. The lower treble, on the other hand, operates in such a manner that the notes sound tamed, despite the fact that they were originally extremely energetically presented. I believe the notes' smoothness and detail are due to how the treble balances the note's weight and intensity to produce a resolved and natural response. Tracks like 7empest by TOOL sound very organic, especially in the opening, which allows the guitar to sound rich and realistic while not allowing any metallic timbre to surface in the mix. Nuances that bring an engagement are not well received, but this allows the track to sound very natural and resolving. Consequently, the overall presentation of the treble area is natural, smooth, and nicely resolved.

Mid Range​

Moving on to the midrange, which is what anybody would pay for, it sounds quite prominent in the mix, with adequate noteweight and emphasis to bring forth a variety of subtleties and emotions. I wouldn't describe it as an expressive sound in terms of energy or forwardness, but it is polished. I believe the precision of the notes is quite exact, whether I am talking about placing or differentiation across the region, which results in a very engaging and spectacular reaction.The upper midrange provides amazing energy in a well-controlled manner, allowing the nuances emphasized across the area to create remarkable synergy and coherence, eventually sounding extremely lifelike, as if everything is occurring right in front of me.I believe that no other brand or IEM in this pricing range can match this level of responsiveness. The lower midrange emphasizes a little bit of warmth, allowing the response to sound tonally pleasing and correct. Great note weight and density create that richness and fascinating response, engulfing in its enchantment. I believe the response in the overall region peacefully envelops your feeling of attention and refreshes your recall of any tracks or songs you have previously listened to in the most polished and resolved manner possible. Personally, I believe this is the best sounding mid range I have ever heard; of course, I do not have any other IEMs in this price range to compare, but I do know what IEMs from brands such as Noble Audio, Vision Ears, and 64 Audio IEMs in this price range sound like, and I believe these are the best in terms of midrange. Tracks like Vicarious by TOOL and Burning Bridges by Sigrid strike me as realistic and evocative, as if the voice and instrumentation are both exact and defined. I mean that the voices, whether male or female, have remarkable forwardness and depth in their notes, and they maintain the integrity or fullness of each note even when the songs get hectic. I believe the instruments become more revealing, which can be difficult to absorb and overpowering in hectic periods of any track, but the voices mix in and offer a richer, deeper sound. As a result, the overall presentation of the midrange area is polished, resolved, and natural-sounding.

Bass​

Now, when it comes to the bass region, I have a mixed feeling about it. I mean, an IEM bringing such a full sounding bass that doesn't degrade or lose the note's identity makes me love it so much, but there are some areas where I believe it falls short, primarily in terms of dynamic quality and presence in the mix, and I'm aware of how it affects my listening sessions with certain genres. The focus is on the sub bass, which gives appropriate presence for the mid bass to become prominent, balancing the note's depth and richness that makes it feel real. I mean, when I listen to bass guitar or drums, it adds fullness to the mix since the notes feel full, warm, and natural, but in genres like pop or EDM, it lacks wholeness and presence but occasionally nails it. I believe the bass is usually toward the rear of the presentation or mix, which in general sounds fantastic while listening to rock, metal, and pop at some periods, but the prominence of thumps or rumble does not meet my demands. To be honest, I believe the bass has excellent detail and texture, making each note distinct and resolved, yet it lacks fun and engagement. However, the 622B ticks off all of the bass's boxes; it is sufficiently present and performs efficiently. And the reason it doesn't sound as I expected after looking at the graph is because of the way the midrange is set. I believe it was necessary for both extensions, whether bass or treble, to sound the way they do in order to achieve the fullness and richness in the midrange that is unique to the 622B. However, tracks like Miliyah's Kono Yumega Samerumade sound close and very immersive, but when the bass drops, the rumble sensation does not have that vast and deep impact; the notes are noticeably powerful, but they do not allow the presence to fully captivate and build the foundation of the overall track to make it sound complete from an overall tuning perspective. Overall, the bass area performs organically, impactfully, and with great texture.

Technical Performance​

So the 622B has great technical capabilities. Personally, I've heard some IEMs in this price range provide better details and stage, reminding me of Kublai Khan, Sultan, Forte, and so on, but I don't think they're as expecting how great the 622B sounds due to imaging, separation, resolution, and a variety of other factors. Let's be more specific.

Soundstage, Sound Imaging & Separation​

The 622B's stage has appropriate depth and width, allowing for a complete sounding and filled experience since it is more immersive, if not further. I believe that the way the notes are positioned allows for more exact visualization and absolute differentiation between pitches. I believe it is really well tuned to provide such a crisp and resolved response, despite the fact that the stage is not the largest or deepest among its contemporaries.

Speed & Resolution​

I believe the resolution is one of the greatest I've seen, especially when it comes to details; the macro subtleties are completely disclosed and sound rich, but there are certain instances where the micro nuances aren't as stressed in the mix. Though the attack and decay of the notes appear to be properly timed, the naturality of the overall reaction is determined by how effectively and precisely the notes are striking and resolving.

Sound Impressions ​

Sources​

Sony WM1A - While listening to 622B with the WM1A, the response sounded more tonally pleasant and smooth. I believe the midrange is more relaxed without losing expressiveness and definition, while also accentuating the bass and treble. I felt the bass sounded bigger and more vigourous but still felt at the back of the presentation, while the treble sounded more extended and airier without adding more energy to the mix. This allowed for a more expansive sound with better width and depth, making the whole presentation seem smoother and more polished regardless of the tune I choose to listen to. However, I felt the note's resolving pace was less exact than that of other sources.



FiiO M15S - When listening to 622B with the M15S, the response seemed sterile and more immersive, allowing the notes to be incredibly expressive and prominent in the mix. I believe the treble and bass sounded more active in the mix, resulting in a more lively and powerful response. The coherence across the area, particularly in the midrange, felt damaged since the overall response did not sound as smooth as the other sources. I believe the quality of the notes increased, but the overall timbre sounded less genuine yet more clear. However, many tracks, such as Anytime Anywhere by Milet or A Few Sentimental by Kohana Lam, sounded very expressive and full of vitality and character, allowing for a fuller and more complete sounding experience, whereas tracks like Erotica by JAWNS or Kono Yumega Samerumade by Miliyah sounded veiled in terms of low end, losing the sound's faithful approach.

Conclusion​

In the end, I believe Canpur has defined what Flagship IEMs sound like, and their devotion and passion are clearly apparent and heard with the Canpur CP622B. The quality they accomplish is the starting point for the brand's peers to learn and adapt to. I am convinced that no matter who hears it, they will never regret or be upset with the 622B. But, to be more particular, folks who love their midrange or listen to predominantly rock, metal, classical, and other genres would appreciate them like they are their own baby. I can see myself buying them in the near future, which is the first time I've stated in a review. Though I understand that contentment is determined by what you listen to and enjoy, I would advise everyone who wishes to listen to music that sounds realistic and true, therefore these are my heartfelt recommendations.

Thanks to Audio Geek for providing this to me as part of a tour. Disclaimer, I am not an audiophile who goes into every detailed nuance of the audio. However, I can certainly enjoy higher end sound.




These are some beautiful looking IEMs that I have encountered. They come with a nice Eletech cable, whose ergonomics could be better, I felt.

I used an iBasso DX220 Max, everything stock about the Canpur, and for comparisons, I have used Aroma Audio Jewel, which has been long time companion in this journey.

Comfort: The shells are rather large, and probably did not fit me all that well (whose implications you might read in the rest of the review). This is odd, because even the infamous fit of IER-Z1R fits me snug.

Overall tuning: This is very much to my liking. Warm (not overly), non fatiguing sound. Could keep listening to it for a long time.

Technicalities: Stage is quite large, More tall than deep to my ears. Quite precise imaging, and layering. Resolution is top notch. However, this is not the widest stage I have heard, but better than most IEMs

Lows: As I mentioned, I just could not get a great fit, and missed a lot of the sub bass rumble. The BCD driver just could not connect with me. The mid bass hits hard, but could hit harder.

Mids: This is where the IEM really shines. Great to listen to vocals. Very natural and organic sounding.

Highs: Crisp, clean, but not overly emphasised or recessed giving the IEM the nice, warm tonality.

Verdict: Overall, an excellent IEM that is worthy of its price. I could see why it gets the praise it gets. This is despite me not getting the best fit possible. I am sure, if it had fit me better, it would have excelled even more.

Thanks to AG and Canpur for the CP622B review unit.

As always I dont have nor expect incentives of any kind for the review and all opinions are mine.

Overview

Canpur have been making waves in the high end iem segment with stunning iems. The CP622B (herein referred to as 622) are no exception.

The iems are fairly large sized with a stunning faceplate. The iems sport 2 pin connectors and the review units shipped with a 4.4 balanced cable with some
really fancy splitter and connector components.

The iems also came in a rectangular faux leather case with a microfibre cloth and a pick to clean the iems with. The tips are of 2 types - black and white with an orange
sleeve inside.

The iems themselves are resin based and carry impressive tech - 6BA + 2EST + 2BC per side, explaining the need for large shells.

Fit
The shells being fairly large sized, and with wings, have a little bit of an issue with small ears (like I do). I was able to get a good fit with the small sized tips and used the same for the review.
The cables, with their memory wire helped to hold the iems in place, but do have a little bit of tug and cause sensitivity around the ears over time

Sound and Driveability

Inspite of all the drivers in the iem, they are very easy to drive at only 10ohms. This results in being able to be driven by anything from a mobile phone upwards.

The combination of drivers provide the iems to drive most genres with authority. They are quite detail oriented, with the deep rumble of the BC drivers.

Bass - They have strong bass thanks to the Bone conduction driver pair per side. This gives it an immense rumble and slam. On some tracks they rumble the brains out.
Bassheads, this one is for you!

Mids - The mids are present in greater extent when compared to other V shaped iems. These do have a slightly pushed back mids but only slightly.

Treble - With the multiple EST drivers, the treble is fast and very detail oriented, providing a lot of technical cues, be it imaging or stage. There is quite a bit of air to
make the iems sound spacious too. There is no congestion inspite of all the details being thrown around.

Conclusions
Canpur CP622B is a TOTL offering and does well with almost all genre. Start saving up!

Those are the tips that came with the Canpur, i use my own Sedna Crystal tips, i found that the Canpur ones do not fit securely in my ears and they slide out, they seem comfortable though, no idea what brand this is, on the small box it just reads "Canpur":


I love their look and do not find the shell build quality bad at all.
The cable is ok, but it doesn't look and feel like anything special. It also lacks an anti-tangling slider. I actually bought a Liquid Links Venom which i got for a very good price locally, i will pair those two when it arrives.
The fit is exceptionally good, they are like a custom IEM, they completely vanish.
They are also extremely light weight.

They need a moderate amount of power, neither are they extremely sensitive like a Trifecta, nor need they big juice like a S15. Also less than the Anni

As for the sound, these are my impressions after ~3 hours of listening: They are nuts.

Imaging is A+ as expected.

Soundstage is very good, but the Annihilator and the Trifecta stage bigger (I think Trifecta has the biggest soundstage of any IEM i've heard). It's still on the very top end of what you can expect from an IEM. Its soundstage also has a fantastic depth to it, whereas the Trifectas stage is wider. If you have not heard Trifecta or Anni, it will most likely be the biggest soundstage of any IEM you've heard.

If i'm comparing the Canpur to the Trifecta, the Trifecta sounds somewhat wrong. It still has that live factor and the insane timbre with voices and that big bass, but from a technical perspective it's not even close, so it's a completely different IEM with a complete different approach. I still love my Trifecta so i will stop comparing those two.


The Annihilator is my #1 IEM. Currently.

The Canpur has less subbass and midbass than the Anni, more details overall, less details than the Anni has in the treble, but these have more in the midrange / bass.
Anni is more engaging and fun with more bass and more thump, also more treble.
They are bonkers fast.
These have the_best_midrange i've ever heard in an IEM.
Zero problems with shout in the upper midrange / lower treble.
They are incredibly clean and clear sounding. Both male and female vocals are incredible.
These are not for bassheads that want more bass quantity.
The tactility and feel in the bass and midrange is incredible. It's not boosted in tonality though.
Layering / seperation is also A+.

The Canpur is a laser that pierces through the skull directly into your brain, with surgical precision.

Anni sounds bloated in comparison.
Anni has worse voices in comparison, also further away.
Anni does let violins etc shine through more with its boosted treble.

"Malukah - The Dragonborn comes" is just pure bliss.
"Tenacious D - The Ballad of Hollywood Jack and the Rage Kage" is also a clear winner for the Canpur. Oh god, it's an 11/10.
"The Bridge Of Khazad-Dum" from TLOTR soundtrack sounds better with the Annihilator. The additional bass underlines the boosted treble from the violins beautifully.
The Canpur excells in the subbass quality, so "Have You Ever?" by Leprous is another winner for the Canpur, also because of the midrange.
"Supermassive Black Hole - Muse" is extremely difficult to judge, the additional bass of the Anni gives it more impact so it sounds more lively, but the Canpur presents voices better.
"The Grand Duel" from The Kill Bill OST is better on the Anni. Until you realize the drum (?) slaps from 0:37 onwards actually pierce right into your brain and leave an impression with the Canpur that the Anni does not provide.
The best example and a favourite song of mine: "A Demon's Fate - Within Temptation" Voices and tactility: Canpur wins. Initial bass Impact and trailing ends of tones: Anni wins.

While they are super soft and to die for with voices in the midrange, i would not call them warm per se, but definitely not bright either. Maybe a very small touch warmth, but mostly neutral. It does also not sound too analytical, like force feeding you sound informations, it's very musical.

I have to say, this thing sounds awesome when played on lower volume too, which is not the case with the Trifecta in my opinion.

So, in the end: I currently like it more than my Annihilator. Wow!
For some tracks, the Anni still wins and because i'm a treble head i will never get rid of it. While i would only recommend the Anni to someone who really loves boosted treble (that has zero sharpness, but still), i give the Canpur CP622B a full recommendation. I have not heard the subtonic storm and will most likely never own it, its price tag is double of the Canpur and its not even available anywhere anymore.
I think the Canpur CP622B is 100% worth the cost.

Cheers!

Being one of the most hyped TOTL in the Chinese forum nowadays I have to give it a try. Overall, everything is either T0 or T1 among all TOTLs I've listened to except for treble extension. Definitely a worthy TOTL IEM to give a try.

Bass:
Despite having only two BA for the lows it has one of the best bass I've heard on an IEM, with surprisingly low depth and just enough amount, making me hard to believe that this is a sound made by only two BA drivers. As far as I know the BC drivers in this unit are only partially responsible for the bass since they mainly focus on improving the texture around the low-mids, so credit to Canpur for tuning the two Sonion 38 series drivers to absolute perfection.

Mids:
The new Sonion BC drivers simply add magic into the low-mids, deliver impressive energy without getting in the way of the vocals. The vocal itself is on the closer side and is tuned slightly toward the bright side compared with a "reference" vocal tunning seen on the Traillii, but is still amazing for both male and female vocals. Density is not overwhelming but rather is reduced thanks to its excellent horizontal soundstage. I would say I still prefer the Traillii in terms of vocals, but the Canpur's overall performance would be more suitable if you do care about background instruments.

Treble:
The low-treble on the 622B is great, with just enough air and brightness but wouldn't drive you crazy when listening to high-pitched female vocals. This made it much more competitive than the Aroma Jewel in my opinion, which has a bump at 4.5kHz, making the vocals overly bright. However, Canpur had the IEM tuned alright only until about 15kHz. From the FR posted in the Chinese forum it seems like the lack in extension is due to relatively dark tuning after 15kHz. The density is also not particularly amazing, and this could be due to the use of only two EST drivers without treble BA or more EST driver implementation.

Technical:
The horizontal soundstage is amazing, comparable with the Traillii but with way better separation between instruments. Though, the depth and the height are only about average among IEMs at this price point, like that of the Jewel. Resolution is on the better side for its price, but not quite at the level of the Multiverse Mentor and the Viking Ragner Prestige. Overall, it is still an IEM that focuses more on smoothness rather than raw resolution that could sometimes be uncomfortable.

Fit:
The fit may not be for everyone, but it is like a custom for me. The shell itself is on the larger side and I do have relatively large ears that could house Monarch Mk2 and IER-Z1R no problem. The fact that the IEM utilizes bone conduction made the fit even more crucial, so I do recommend trying them out before purchase.
