After wearing them for a few hours, I had a blister on my little toe. The sound stage is wide and nicely accurate. I?ve never had an issue pairing with any device, and going between them is easy. The sole on these slippers is so strong and look as though they will last so long! I use them for conversations and Audible books. I thought I was going to be lucky with these ones and boy was I wrong. Fits 3 rackets, shoes, balls and more! i just want to replace my device . Had less than 6 month and broke. It has a comfortable feel while playing.
