      Functional, sound quality is OK

      I can hear static noise in the background when no music is playing and the sound quality is definitely not the best (you get what you pay for though probably). The noise cancellation is pretty decent, and the magnetic buds are excellent. I wish that the earbuds were a little smaller though, because it hurts my ears if I leave them in for too long because they are too large.

      Best headphones for a runner

      Definitely the best Bluetooth headphones I’ve found at this price point. No, they aren’t the most fantastic sound quality in the world but you’re paying $35 for BT headphones; what did you expect? I’ve only had them for a few weeks but I’ve been on a number of sweaty runs and a few rainy ones too, and they haven’t had any issues with getting wet. Overall I’m very satisfied.
