I have a pair. They're okay. The keeper is the best part. I found that the sound got cut off in one ear at a lower volume level, so I'd have to raise my volume to get stereo again. When I tried them on a call, the other person said they could hardly hear me even though I cranked it up. Lastly, the seal was so good in my ear, that it created a vacuum type feeling in my inner ears so it kind of made me dizzy.
I gave the headphones to my husband and I reverted back to my Apple headphones.
