The sound quality coming out of the headphones is pretty nice. However, if you are using headphones while doing an activity then prepare for them to fall off of your head. I used them while mowing my lawn, and I had no luck keeping them on. Finally I ended up putting my ear between the clip and ear piece so that they stayed in place. If they wanted me to use this technique then there is really no need for the part the goes behind your neck. These headphone are way too wide, and there is no way to adjust them smaller. These are great if you are sitting down and listening to music, but if you are on the move then go with something else.
