Canpur Performance series: CP54E (4.4mm)

Very comfortable but fancy sound. Hugh resolution and clear separation. Ifa narrow staging is ok, this is the end game.

The mid-high range is excellent, so I can enjoy vocals comfortably. The bass is also sufficient. It is not inferior to the CP622B. The CP622B tends to have a flat sound across the entire range. However, the CP54E feels energetic in the mid-high range. If I want to listen to any song, I might choose the CP622B. But if I want to listen to vocals, I choose the CP54E.

A top-tier IEM that rivals the best

I own a handful of TOTL iems and this IEM really nails it on so many fronts. It's a great, rich sound with zero fatigue (I'm treble sensitive). The highlights: - Amazing fit (for my ears at least). It seals so well it feels almost custom. - The bass should put to rest the usual BA-bass jabs. It is big, bold and full. It is not super articulate but nevertheless very satisfying. - The mids and highs are beautifully tuned. Crisp, airy and just really satisfying. They are not ultra-technical but I don't think they're aiming for that. It's just a beautifully tuned IEM that I predict will become a real cult favorite. It's outstanding.
