Ever since I bought these earbuds I've had bad connectivity issues especially with pairing. I tried connecting both the computer and my phone with he earbuds and that's when the issues started. A week ago I finally managed to control the sound through my computer after resetting it but recently it started having pairing issues again after using the microphone. I have no idea what's going on. That being said the sound quality is pretty good and they fit nicely. Although I wouldn't recommend them for exercising.
