While I do not have the habit of carrying a pair of sunglasses everywhere I go, they were great to have while I was outdoors, whether at a picnic or lounging by the pool. Pairing the frames to your mobile device is very easy. Just download the Bose Connect app and let Bluetooth do its thing. Once paired, I did not experience any instances of sound dropping out. The high quality of the sound really wowed me. It was surprisingly crisp and clear, even though my ears were not covered.
