I just got one, and the audio quality is decent. I'm starting to really hate having cables dangle around, and having to finagle with a player amp stack. The clip is solid and a bit too tight I think, but it's very slim and does it's job. I got cutouts at weird places that I didn't with my Bose, but they stopped when I held the phone in my hand. Need to test some more. The fit is nice, holding firmly around my ears. Haven't tried the call/microphone. Bit annoying is the control scheme where you have to hold on to volume up for 3 seconds to skip a song etc. It's not double or triple clicking any button. Turning off is middle button 5 seconds, pairing is middle button 7 seconds. It works fine if you are watching the little light. Paired with my SE846 it's a big improvement over my bose soundsport, but then this is not water resistant. I'm bummed that my S9+ doesn't do AptX HD.
Thanks for sharing this. I was looking pretty hard at these and almost pulled the trigger. Still considering them and will and will probably need to get something for my SE535s now that Samsung is ditching the headphone jack as well. The control scheme seems similar to the Mee Audio BTX1 that I currently use in the office with my SE425s
I was also bummed when I found out my S9 does not have aptX HD.
