Either different batches have different tunings for people aren't perceiving the differences. Coolhere UFO had awful driver matching and a bright tuning, while BE30 Air had a flat tuning but again poor driver matching (this time more mids and treble on the left). I'm wondering if any Aliexpress seller has released the AptX version yet.
I'm looking for another AptX + USB-C + Wireless charging combo (latter is preferable but optional), but preferably one with more mids and treble detail than the Sabbat E12 Ultra, which I found reasonable except for that poor driver matching. I was set to get Wavefun Xpods 3T until I read some comments saying the originals were muddy or "flat". Same with the Whizzer B6 being said to have more bass emphasis.
Have been lurking the thread for a couple of days since I was looking for tws with similar criteria too, ended up ordering shanling mtw100. It seems to fits my requirements very well, except no AptX, but it still receive a high praise from reviewers in terms of connectivity and SQ. Plus it has a pass through mode, making it suitable to be worn in office/public environment, wireless charging, good batterylife and ipx7 rating too.. and BA drivers for that sweet2 clarity and mids.. seems so perfect Can't wait for it to arrive.
