For such a low price, the sound quality is terrific. The seal blocks most outside noise so you can hear the music perfectly.
The mic isn't the best but if it works fine and is only an issue if you whisper. Speaking at a normal volume means the other person can hear you fine.
Turning on as soon as i take them out of the case and not having to turn them off before putting them back is much more convenient then some other wireless earbuds.
The design means they're very comfortable and never fall out during the day. The case is also sleeker then previous models so it doesn't feel like carrying to wallets. I forget it's in my pocket most of the time.
The touch features take a bit to get used to since you need to learn how much pressure and on what contact surface. But after a while it's pretty easy to remember and use.
For a such a low price, they lasted much longer than my headphones. More than worth the price.
