I love these headphones! I had purchased one set before my daughter brought them to my attention again recently. I had not used my first purchase very often because I purchased the wired set. I use a C-Pap and often experience the need to get up during the night. I tried putting the headphones under the C-Pap headgear and on top of the headgear but got frustrated when I would get tangled up in it. But then my daughter explained that the newer headband could be purchased in different sizes (the first one was a bit loose) and I wouldn't have to "charge" the wired kind and it was best worn with the cord attachment in the back. Don't know why I didn't realize that when I first put them on! But I also discovered that I could adjust the headphone speaker to the exact place I needed it to be for best sound. Also being deaf in my left ear, I found that the right speaker was more than enough to give me quality sound without extreme volume! I say GO FOR THE fun RUNPHONES!
