I really enjoy how customizable the audio and controls are. They do feel pretty secure especially considering I have a smaller head. Could definitely use this in the gym.The control options however are a little annoying. The way to change songs and change volume are swiping up/down and side to side on the outside of the right earpiece. If you want to use these controls, you have to swipe PERFECTLY in the direction you need to, and if you don’t you’ll do something completely different.The headband is also slightly uncomfortable. It’s thinner than most headphones and not as squishy, and despite it being pretty light, the headband causes quite a bit of pressure on the top of my head. If I’m wearing it for long periods of time, I have to move the headband every once in a while to relieve the pressure from that spot. After a few hours my head begins to hurt.Although it hasn’t broken, it feels pretty fragile and I’ve seen many cases where it’s broken at the thin side pieces so beware of that as well.I’ve heard many great things about the xm4. If you’re looking for premium headphones, consider looking into the xm4 instead since I believe the audio quality isn’t much different (plus it’s a little cheaper)
