Six hours of music playback is legit—I charged them once and they got me through my whole shift plus the commute home. The 10-15 meter range also means I can leave my phone on the charger in the kitchen and still switch tracks from the living room without a single dropout.
The battery life honestly surprised me, six hours of music on a single charge easily got me through a full workday and my commute. Connection held steady even when I left my phone on my desk and wandered to the break room, which is about 12 meters away.
Pairing took less than a minute and the connection stayed solid even when I left my phone in the kitchen and wandered to the backyard, which is about the full 15 meters. Charging them for an hour before a long work call gave me the full 5 hours of talk time without a drop.
