Sound Impressions: Lows
Let’s start off by describing my take on CP622B’s overall sound in a short simple sentence. The CP622B desires a clean, calm W-shaped sound that makes subtle yet vivid impacts. That may sound vague as the terms “subtle” and “vivid” are odd to co-exist, but let me break it down as we continue with the sound impressions. First is the bass. My first impression of the bass is that the micro-inverter tube design does seem to impact the bass performance immensely. The bass provides deep and rich vibrations that rival dynamic drivers or even bone conductor drivers.
The irony is that I thought CP622B assigned the dual bone conductor drivers for the bass instead of the Sonion BA woofers, as CP622B’s bass was far different from what I’d usually hear from an IEM with the BA-driven woofers. I couldn’t tell the BC driver wasn’t involved despite an extensive listening session for the review. I guess that pretty much explains how well Canpur utilized the woofers and brought out the best of the bass drivers.
Another element that sets the CP622B apart and unique from other TOTL IEMs is its incredibly responsive bass. The deep-diving bass keeps good quantity control across the mid-bass range while maintaining a strong presence, hence delivering snappy yet deep lows that bring out pleasing liveliness and bass dynamics. The CP622B’s natural yet fine-controlled ultra-lows and mid-lows create an extremely even, expansive atmosphere.
Let’s go a bit more in-depth about the bass quantity. the lows are robust and full-bodied without being overwhelming, with the overall bass quantity/presence being closer to slightly v-shaped but lesser than strong V-shaped, so sitting right in between those two. It’s the right balance that would satisfy most users – those who want agile and lean bass and those who prefer thicker, punchier bass. Canpur CP622B thoroughly qualifies both of two worlds which is why I believe they’re getting their applause with the CP622B.
Sound Impressions: Vocals
The CP622B’s vocal tone is dark-bright. Saying “dark-bright” might hit you confused if comprehending literally, though many will likely agree why I’ve used such an expression once listening to the vocals of CP622B. The vocals are deep and serious yet highly transparent and clear, offering a refreshing sense of air and openness in the high vocals. The pleasant airiness and shining transparency applied across the range pair well with the calm, thoroughly smooth, and neutral-bright vocals.
Based on these features, the CP622B’s clean, pitch-black background tone makes this “dark-bright” experience possible for the vocal range – solemn and in-depth while also being cheerful and crisp in presentation. Apart from that, the vocals are creamy, with high resolution and texture, making them comfortable to listen to while still detailed in expression. The vocals are slightly forward to prevent them from being overshadowed by the robust bass, and they transition smoothly without interference from the mid-lows and lower vocals.
Vocals flow with great stability and coherency throughout the range, causing no noticeable dips, tonal distortions, or sibilance. The CP622B gives a subtle “sip” on the upper mids (around the frequency range where the sibilance would happen) but it never develops into sibilance or causes fatigue but instead gives a fun, realistic ‘bite’ to the vocals – the way how female voices reaching in high tones would sound in real life.
Sound Impressions: Trebles
Reproducing crisp, detailed trebles while not getting aggressive in quantity or tiring to the ears by any means is one tricky task unless you’re willing to sacrifice some portion of details and resolution. For those TOTL IEMs I’ve mentioned to be very satisfying in resolution and detail without fatigue, it’s inevitable even for them to eventually come to a point where they get tiring. Well, in fact, all IEMs would regardless of any price, and sound signature; it’s just a matter of time, or how long it will stay fatigue-free.
As for CP622B, Canpur did exceptionally well on how to keep the trebles as smooth and calm as possible while also being daringly silky and highly detailed. I would like to describe CP622B’s trebles as a sneaky yet charming intruder – the trebles are very calm, solemn, and quiet as if existing only to assist the lower frequencies, yet its treble performance rubs shoulders with TOTL IEMs that strongly emphasize high frequencies.
So how does CP622B make that possible? To my ears, I’d say it’s a matter of penetrativeness – how clean and clear they are, in both separation and pure resolution. It’s the perfect tuning for those who want the blissful, silky swirling of treble details that EST driver typically delivers but are also too treble-sensitive to use other flagship IEMs that are known for excellent treble extension. The details and resolution are almost just as penetrative as those IEMs but CP622B’s thoroughly calm nature persists even to highs and ultra-highs, not only keeping tonal coherency throughout the sonic spectrum but also making it extra fatigue-free.
