The highly flexible silk diaphragm reproduces powerful bass and clear highs up to 40kHz for enhanced clarity. 40 HOURS PLAYTIME: Active noise canceling headphones can play music for up to 40 hours in noise canceling mode. Standard mode extends playtime to 60 hours, while a 5-minute charge gives you 4 hours of listening.
