Non-audio Summary: A light-weight Bluetooth headphone with APTX codec support and a fairly durable build. It can be easily connected using NFC, and has a touch panel that supports gestures for volume, pause, next track, and assistant. The battery life is superb. I’ve used it for a week and it didn’t even bulge on the seventh day. Same battery performance as my KZ T10, which cost twice as much as this headphone. The build is all plastic except for the adjustable hinge. The fit is very nice; it does not suck my ears and hurt the upper part of my head like what KZ T10 does, and I can also use it for hours, unlike KZ T10 that fatigues me within 30 minutes of listening. This headphone can also be used wired and has a very nice sounding microphone built into it.
Audio Summary: Smooth and organic-sounding, it makes you want to fall into a reverie and just chill and relax to the music. It has a laid-back sound (excellent for jazz, Bosa Nova, and the like), leaning towards a mild-V sound signature with emphasis in the lower treble. The bass is very good; it’s fairly balanced with a good amount of thump and rumble without veiling the melodic frequencies or the midrange. The midrange is a bit recessed and soft-sounding but still renders enough details (like backing voices and atmospheric echoes). Treble is also very good; it’s quite smooth and does not sound harsh or peaky at all. There’s also enough brilliance and air that makes the P23BT open-sounding and wonderfully avoids sounding too compressed or narrow. The soundstage is fairly out of the head, with good height and width and a below-average depth.
Non-audio Summary: A feature-packed Bluetooth headphones, well-built and has a nice weight to them, has active-noise canceling and ambiance mode, has an innovative volume knob design, long-lasting battery life, easy to pair, has AUX mode, has USB type C plug, has high-quality leather pads, has metals everywhere and finally has long-range connectivity.
Audio Summary: Very good for relaxed listening, smooth and laid-back, tuning may be too safe for some, lacks specialty, upper treble is rolled off, average soundstage and imaging for a headphone, microdetails are muted, lacks sparkle and treble bite. Bass is unexpectedly tight but lacks control sometimes specially in complex tracks. Midrange lacks clarity and nuance. EQ can somehow fix the upper treble roll off.
