I believe they are designed solely for apple products

I worked out in them the first day after fitting the right bud size and fin size

I tried hard to rock my head around during vigorous exercise and these headphones stuck in my ears like glue

Cr tells us that we should hear an echo throughout the song and with these headphones we do hear that faint echo and also a swirling sound that moves from the left ear to the right and then back and forth again

Summer from vivaldi’s four seasons is next on the cr list of test songs

Sadly the headphones even pick up people coughing or clearing their throat in the audience

I think a big part of the sound difference is that i get a full seal in my ear that stays put

Maybe too good of an ear seal as they shut out outside sound so well i dont think i would wear them for outdoor running or biking as it would not be safe
