i couldn't even experience all the supposed features of these earbuds because they kept falling out. the body is about the size of a large marble and there is no way to get it to latch on or hook under any part of your ear. trying to force it just caused instant pain and discomfort. the only thing that kept them in for the small length of time i was able to wear them was the ear tips, but even just talking while wearing them and you could feel them slipping out. the whole experience was completely frustrating. i really wanted to like these earbuds, the features sounded great, but they're completely useless if you can't wear them.
