I'm mostly using them with a s9+. I tried switching the codec to AAC but the phone switches it right back Sometimes I'll use them with a iPhone 6 (work phone), but that is rare. I took them on a run in Saturday and was pretty happy with them.

So i have been busy at work and haven't had a chance to give it a full test run. I have mostly listened to the headset with one earbud in (left only of course). I have only listened with both buds in for a few hours at a time, maybe 2-3 times. The thing i notice the most is this "chime" that...

I recently just bought a used set of buds from the Amazon warehouse So far so good, volume is good and connectivity I haven't had too much issue with.
