Used it with S9+. Sound kept muting at irregular intervals during music and movies. Its not like a pause more like skipping. There is silence for a couple of secs then the sound resumes. Tried full charging. Tried gaming mode etc. The sound is great but the muting takes the fun out of it.
Almost returned it. Turns out all it needed was a cache clear of the Bluetooth app under settings. Working beautifully now for the past 1 hour. Will see iow it goes for a couple of more days.
I am keeping these for myself if they keep working without issues.
