Control your music directly from the headphones. Simply tap the earpieces to skip to the next track, go back to the previous track, or restart the song. Answer your calls by tapping one of the earpieces. No need to take out your phone. The headphones recharge in their case, which in turn recharges via USB-C. Sound output is limited to 85 dB to protect children's sensitive ears, while still delivering optimal sound quality.
