I bought these a while ago and ended up returning them soon after. During the first week of use they were alright, then everything went sideways from the second week. The connection kept dropping out if you were walking or if the phone was in your pocket or both. Even if I tiled my head to a certain angle whilst standing still the audio would drop out. The fitting was also uncomfortable. Like it fit, but it started aching after 30 mins of use. I tried fiddling with the fitting but didn't help much. These are premium earbuds and you would expect them to at least have nailed the basics.
