Head-fi review: Number 49 of 100... a limited edition from Canpur
1. Introduction & Positioning
The Canpur CP622B already had a reputation as one of the more unique flagship IEMs on the market thanks to its dual bone conduction drivers and a tuning that blended musicality with a spacious, holographic presentation. The CP622B Ti builds on that platform but aims for more refinement: slightly leaner low end, more open mids, and a brighter, airier treble region. Instead of reinventing the wheel, Canpur has adjusted the balance for those who wanted the magic of the original but with greater technical polish.
2. Build, Design & Comfort
The Ti edition carries a sleek, metallic finish that feels more premium and solid in hand compared to the original’s glossy shell. The ergonomic shape remains comfortable despite the bone conduction module inside. The included cable feels supple and lightweight, avoiding stiffness and microphonics. Overall, it’s a high-end fit and finish worthy of its flagship price.
3. Sound Overview
The Ti’s tuning steps away from the original’s warmish presentation and moves toward neutrality with subtle energy in the upper frequencies. The end result is a more reference-oriented but still musical IEM, perfect for those who want detail retrieval and a spacious stage without sacrificing emotional engagement.
4. Lows (Bass)
CP622B Ti: Sub-bass reaches deep but is no longer the centerpiece. It’s tight, punchy, and has faster decay, emphasizing texture over sheer volume. Bass lines are articulate and controlled, ideal for acoustic and progressive genres.
Original CP622B: More sub-bass heft and warmth, giving cinematic and EDM tracks a weightier foundation but occasionally masking mid detail.
Empire Ears Odin: Similar speed but slightly more mid-bass emphasis; Odin feels more energetic but also more forward in the low end.
Amber Pearl: A warmer, rounder bass signature than Ti, providing a lush foundation but less agility.
Other Flagships (e.g., Elysian Annihilator): Many emphasize slam over detail. Ti’s bass feels more balanced and less fatiguing for long sessions.
5. Mids
CP622B Ti: Clean, spacious mids with a natural tone. Vocals sit slightly forward, free from bass masking. Instrument separation is excellent, with an almost “out of head” holographic feel from the bone conduction system.
Original CP622B: Slightly warmer mids that feel richer but sometimes less transparent in complex mixes.
Odin: Brighter upper mids and more aggressive vocal presence; Odin brings energy but can feel fatiguing over long listening sessions.
Amber Pearl: Creamier, intimate mids, perfect for vocal and acoustic music but with a narrower stage compared to the Ti.
Annihilator & Maven II: Both are mid-forward detail monsters, but Ti’s mids are smoother and more relaxed without losing clarity.
6. Highs (Treble & Air)
CP622B Ti: Treble extension is improved over the original. Cymbals, strings, and micro-details have more presence and air. There’s sparkle, but it’s tastefully restrained—enough for detail lovers but smooth enough for long listening sessions.
Original CP622B: Airy and smooth, but slightly more relaxed. Some might have found it a touch too polite up top.
Odin: Brighter, sharper treble with more bite; more “analytical” and aggressive in comparison.
Amber Pearl: Softer treble, designed for fatigue-free listening. Smooth and romantic but not as resolving as Ti.
Annihilator: Extremely treble-forward, more energetic and brilliant than Ti, which may excite detail lovers but fatigue sensitive listeners.
7. Soundstage & Imaging
The Ti retains the original’s standout feature: a holographic, three-dimensional soundstage enhanced by bone conduction. Where the OG sounded like a warm concert hall, the Ti is more like a high-end mastering studio—spacious, but with sharper imaging and more defined placement of instruments. Layering is excellent, and even dense tracks don’t collapse.
8. Technical Performance
Resolution and microdetail retrieval are improved over the original CP622B. Transients feel snappier, and imaging cues are more precise. It doesn’t chase the ultra-forward resolution of Odin or Annihilator but instead finds a balance—clear, detailed, but still organic and easy to listen to.
9. Comparisons at a Glance
CP622B OG vs CP622B Ti: OG is warmer and bassier; Ti is cleaner, leaner, and more open with better treble detail.
Odin: Brighter, more aggressive, more mid-forward; Ti is smoother and more relaxed with bigger stage.
Amber Pearl: Richer and more intimate, excellent for vocals but less spacious and less airy.
Annihilator 23: Extreme treble detail and forward mids; Ti is more balanced and comfortable.
Maven II: Reference-neutral with a smaller stage; Ti feels more immersive and musical.
10. Conclusion
The Canpur CP622B Ti is a thoughtful evolution rather than a complete overhaul. It sacrifices some of the original’s lush bass and warmth for better ba...
Listening with Leo's switch tuning 'ON', if I were to describe it in one sentence - very coherent, natural, musical tuning with top tier technicalities in the best possible way. If you are looking for a top tier all-rounder, look no further than the Pentara. With the amount of drivers and crossovers, it is impressive to achieve such technical details and tuning at a truly flagship level. Buy with confidence if this is what you look for
Pronounced and very high quality, tight, punchy, textured, controlled bass. Mids with enough warmth, emotion, note weight. Never thin or analyctical. Treble that provides clarity, detail, and air without sharpness and fatigue for me. Very deep and wide soundstage that expands like a sphere. Excellent resolution and imaging. No congestion. I do not have issues with anything in the frequency range that I can fault personally like I do with other IEMs. Everything just sounds right. Nothing sounds artificial or weird. Not recommended for bassheads seeking for more bass but rather for those that want neutral-warm leaning sound with pronounced and elevated bass.
UM's tuning switch '1' leans slightly less bass quantity, more clarity, and opens up the soundstage a little bit
Two different tunings that are noticeably different but useful from each other rather than being inferior. Easy to use the switches that compliment each other with tacticle sound
90% of the time I will prefer the switch on with Leo's tuning because it invokes a lot more emotion and dynamics with the elevated bass and warmth in the mids. Just my preference
Fairly easy to drive but scales with power or better DAC/AMP
Only major gripe I have is that the stock cable sucks tbh. Not ergonomic, heavy, stiff, minor microphonics, emits a minor sinewave hiss with my DAP as a USB DAC which I do not have with other cables. Recommend using a better cable up to user's choice
I notice that the treble does get a little spicy with poorly mastered songs with elevated treble though that is fairly rare
Lack of accessories and unboxing experience is not a big deal if you are ultimately chasing the sound anyway
As a self-proclaimed Astell fan and current owner of an SP3K, I hesitated quite a bit before upgrading to the SP4K, wondering if it was a halfway point (like an SP3.5K). I also wasn't particularly interested in an open-source Android system. Fortunately, I decided to take the plunge. The SP4K has turned out to be a complete surprise, to the point that it's the best DAP I've ever heard in terms of sound quality. A huge soundstage, bass with a texture I've never experienced before, and an astonishing level of detail. A total success.
These punch way above their price point. Very good bass for ba drivers that doesn’t make me miss dynamic drivers. Great technical performance, extended treble but not harsh. Love this set!
