I received these headphones via the Amazon Vine program. They are terrific! A few months back I bought a different pair of similar over-ear headphones that wrap around the back of the neck, to use while skiing. I find open-ear preferable because you can still hear people around you, helping to stay safe, you can also talk to people on the chairlift. Any sports activity is safer without earbuds that tend to shut out all external noise.
This pair is superior to the pair I purchased earlier in a) comfort, b) sound quality (to be fair, it's close) and c) practicality - this pair has tiny buttons behind the ear for volume and play/pause. My other pair has touch sensor which seems great but is actually quite difficult with ski gear on and no tactile feedback. This pair also has 32gb memory built-in, so in theory you can listen without a cell phone, however I think you need a phone to access the app to control the music. I'm not entirely sure, I have not tried this yet.
My one complaint is that it uses a proprietary charging cable (it also acts as the transfer cable for saving music to the internal memory card). So you need to bring the specific cable if you anticipate needing to charge the headphones during your trip.
