Unfortunately my 65t broke after about 5 months of use. The 65t has great utility (call quality, hear-through function and button controls are good) but falls short on comfort, isolation, durability and defects/quality control. Sound quality is good but also depends on what seal you get - the large tips give the optimal seal to hear the bass for me but were also very uncomfortable as the flange would flip back in my ear. I used medium tips and could still hear the bass at home but I start losing seal once I'm commuting. The overall sound is V-shaped with an emphasis on the upper-mids and highs, without sounding sibilant or fatiguing. When I can hear the bass, it's somewhat boomy and emphasized in the midbass. Charging case still uses microUSB, unfortunately but I suspect the next version will have Type C as the 85h has it. Many users have complained about volume imbalance, clipping distortion and hissing from the left bud, which no firmware update has been able to fix (last one was in December). I have this issue but don't know if it is system-wide. The hissing is only imbalanced above a certain volume, while the volume imbalance and distortion happen regardless. The imbalance for me is slight (it sometimes "settles down" slightly after a few second of playback), but recently my right earbud died down in volume significantly. Sometimes pushing it into my ears cause the volume to come back briefly - I suspect the driver or internal connection has become damaged - I was noticing driver flex on the right bud out of the box.
Astrotec S60 (BT4.2) is my daily driver now but I'm considering getting the S60 BT5.0, Sabbat E12 or Anbes 359. I'm wondering how's the volume of E12 and 359, although I suspect my Note 9 is keeping the volume low on the S60 (it sounds very loud through my laptop).
