These are the best underwater headphones, but that doesn't make them comfortable. They do stay in your ears, unlike other headphones, and the sound quality is fine.
Not sure why they're so much more expensive than they were two years ago though. They've doubled in price.
I was a little dubious a first but the price was so cheap I thought I must give them a try and they are brilliant yes I would recommend them and the sound quality is good as well.
