It sounds best at low-to-moderate volumes. The buttons are easy to use, built in FM radio mode, design is sleek and material is high quality these are great for LISTENING to music the only down fall is the fact the mic quality is so poor although that isnt a necessity for me it might be for you and if so these arent the head phones for you, but you are still getting an amazing deal! On the side of the earbuds is a small button which can be used to control the music (skip, next) phonecalls (awnser, hang up), start the voice assistant and power them on/off. Size is perfect: I wear 8. VERY worst product ever I’ve received from amazon & crocs as well. Nothing five minutes of 80 grit sandpaper couldnt fix. these are definitely worth looking into* If your head is huge. They hold my feet perfectly for a better movement while playing. I really like this concept. So, it might just be me.
