Canpur CP752B

I still remember the first time I heard Canpur 622b and was completely smitten with the intoxicating mid’s and sparkly but dry treble. The bass had nice texture but was a bit lackluster, a bit too rounded and lacking extension. The mid’s stole the show and at this time I was very focused on engaging mid’s and warmth over all else. Since then, my tastes have evolved and the first few minutes of listening to Canpur’s latest flagship the 752b I knew I was going to fall hard for its sound as it hits very very close to my current preferred taste. Engaging, clear, hint of warmth, extended and resolving treble, spacious and resolving mid’s with a supportive deep hitting bass. My only negative is the lack of DD bass timbre, decay and slam.

The Canpur is insanely detailed and technical. It literally just pours out information in the most liquid way possible. No shout, no fatigue. A huge open stage with notes that seem to float around you. The tonality is a bit more dry than textured throughout the FR but not to its dismay, it works for the tuning very well. To quote @aaf evo “Ugh I love 752B. Idc if this sounds like 3 year old water it’s the tastiest stale water of my life” I love this statement because…well…its funny but more so because it so accurately describes how I also vibe with the 752b. Or another way of saying it in more romantics terms, is that 752b is luxuriously refined. It works very well as an all rounder for me.

Bass is not the star of the show here but it also does not take a back seat. The bass is very satisfying, deep and rumbles nicely when called upon. Although you will not feel the push of air like that of a Dynamic Driver or hear an earthy timbre. It does still fill the head with nice reverb that is not distracting.

Mids are naturally distanced with plenty of space around each instrument/voice. Imaging and layering is spectacular here and nothing ever feels even the slightest congested or smeared. The stage is quite spherical, to my ear equidistant in all directions out of the head. Notes are not dense but more dry, light with super sharp transients from edge to edge of notes. Notes seem to float instead of feeling anchored. They float in there correct places with great stage structure. My only teeny complaint is the timbre of vocals and acoustic guitar can sound a bit thin at times. It’s not a deal breaker as it’s not to the point of being annoying. However it is how I hear it.

Treble is very resolving, layered and extended. There is a very occasional peak but for whatever reason it doesn’t come across fatiguing or piercing, to my ear I hear it like a very pronounced sparkle. The treble isn’t as dry sounding as it was on 622b and it is much better extended than that set as well. It still has a dryness to it but also a nice thick outline to the notes with defined edges.

The Dynamic range is also wonderful. Macro and micro dynamics swing with ease and shift in accordance to the music playing. Every nuance is heard. Imaging reached 3D holographic levels. This is true Summit techs. It is extremely immersive and even at low listening volumes nothing is compromised. 752b is so easy to drive as well. I used both the Quloos MUB5 and Ibasso Dx340Ti, both work very well for 752b. The 340Ti having better treble res while MUB5 offered a slightly richer tonality.

The 752b has really taken me by surprise, I held off on purchasing it for awhile as I thought it would bore me or become too much over long listening sessions but both could not be further from the truth! It has truly captivated me and is in good complementary rotation. Going to Fulgrim from 752b reminds me why I love the Fulgrim and going to the Asteria from 752b again reminds me why I love the Asteria and vice versa going from each of those to 752b reminds me why I bought the 752b and have fallen hard for its sound

The Canpur CP752B is nothing short of a revelation in the "summit-fi" landscape, effectively redefining what a flagship multiverse-driver IEM can do. The first thing that grabs you is the sheer scale of the soundstage—it is genuinely holographic. Where other IEMs might give you width, the CP752B uses its dual bone conduction drivers to create a 3D bubble that feels less like listening to earphones and more like sitting in a properly treated listening room. The separation is surgical without being sterile; you can pick out every layer of a complex track, yet the drivers—despite being a mix of BA, EST, Planar, and BC—blend with a coherence that is almost impossible to find in other "quadbrid" sets.

Tonally, these strike a brilliant balance that many are calling a refined "W-shape," bringing the best of all worlds. The bass is authoritative and massive, providing that visceral, textured rumble you usually only get from dynamic drivers, yet it retains the lightning-fast speed of balanced armatures. It hits with a weight that provides a solid foundation for the music without bleeding into the mids. Vocals are pushed forward just enough to be intimate and engaging, avoiding that distant "scooped" feeling, while the treble offers that elusive "sparkle without pain"—delivering immense air and micro-detail that extends forever without ever becoming sharp or fatiguing.

Finally, the build and package cement its status as an endgame monitor. The medical-grade resin shells are surprisingly comfortable for the driver count, and the collaboration with Eletech for the stock cable shows Canpur didn’t cut any corners. It is rare to find an IEM that manages to be both a technical monster and musically "fun" at the same time, but the CP752B pulls it off effortlessly. If you are looking for an IEM that competes with (and often wallops) sets costing significantly more, this is absolutely the one to beat.
