I have to say, these have some of the most plush and comfortable earpieces that I have ever tried. I could say more but i dont do spoilers! They are not noise cancelling, of course, which is great because I can hear Youtube guitar lessons as ambient sound while Im playing the guitar through the headphones, without having the computer speakers much louder than "normal". I was skeptical about buying it because there were no reviews, but its actually a good buy. Bottom line, these are excellent wireless earbuds that will satisfy your listening pleasure. CONS:1) The bottom rack has small magnets that are supposed to hold it in place when theyre folded. Ran a little large and had to be returned. Note to put the wet shoes on the bottom shelf to avoid dripping onto other shoes. So this is a design flaw. You have to scroll left to see heart rate data (btw?heart rate monitor works well?.
