my Airsun X8 has arrived. my short review/impression on this:
the unboxing was really barebone. the box is black with no markings, with no plastic wrappings, the manual is printed in a really crappy paper.
but the unit itself is quite nice. it's got that velvety rubber coating all over the case and the earpiece itself. the material is solid.
it has a short TWS nozzle like the Jabra and Mifo o5, and the case is shallow, so eartips selections are limited. i use the Tennmak Whirlwind on mine
it uses 4 mic arrays (one on the outside, and onr in the inside) like the XM3 for ANC. compared to the Dyplay BQC35 which only uses 2 mics (outside only)
ANC is about the same level as the BQC35, but it differs slightly: the X8 slightly muffles the highs more than the BQC35, but the BQC35 reduces lowest rumble slightly more. so it's a toss up depending usage. the X8 has slightly better passive blocking.
also note that the BQC35 ANC would clip if there's a sudden clicking noise (like turning on light switch, dropping keys on glass table, or clapping). not a deal breaker, but it's there. the X8 and XM3 don't have that problem.
but my X8 with ANC on would make that buzzing noise on the left earpiece if i cupped my hand and touch it (like when you touch the guitar cable jack when connected to an amp). the right one doesn't have that problem.
Call quality is no contest. the Dyplay BQC35 has one of the best and most natural mic sound that I've tested.
ease of use, the X8 can control all volume, track skip, and play/pause from either left or right unit. but the double click or triple click scheme is a bit finnicky. the ability to turn on/off from the earpiece is also a plus for me.
Sound signature, the X8 is mid centric with a warm veil across the freq. bass mids treble are about the same level (the BQC35 is a subbass monster with recessed mids in comparison)
the treble of the X8 is a bit too warm for my taste. the good thing is this sound won't be fatiguing even for long sessions.
overall I'm quite pleased with this X8. i think between the WH and WF XM3, and the BQC35, my ANC needs for now are about covered
