At such a low price, you really can't go wrong with these. The sound is decent, they connect fast and are comfortable. They don't sit flush against my ears like they do in the pictures, instead poking out. But they've never come close to falling out during exercise. The only reason I don't give 5 stars is a bug I experienced, where each air-dot disconnected from each other and started acting as an independent BT device. A quick google search managed to solve this, but better instructions would have saved me 5 minutes here.
