These have a surprisingly nice, and well balanced, open sound. Much better than what I was expecting for the price. The buds aren't the most secure but they are pretty comfortable. Easy to work despite few clear instructions on the packaging. Bluetooth doesn't cut out randomly, however there is a slight delay! It isn't noticeable if you're just listening to something, but as soon as a video is played the syncing issue is painfully obvious. I got these for listening to stuff at work, so it's not a deal breaker for me. But it definitely could be for some.
