85dB volume limiter to protect against hearing loss - safe for 8 hours of listening (limitation is accomplished through DSP in the CSR chip under Bluetooth mode). 3.5mm Auxiliary cord for wired connection has a resistor in the cable that passively limits if needed. *82% ambient noise isolation at 1 kHz - passively blocks out a significant amount of ambient noise so that lower volumes can be heard with great quality in noisy environments (ie. Airplanes, buses, crowds, etc). *Puro Balanced Response frequency curve - flat frequency response curve that delivers studio grade music and vocals the way the artist intended. No muddled bass or treble, so that vocals can be heard crisp at low volume levels. *18 hours of battery life - great for long distance travel and minimal charging. *Durable aluminium and protein leather construction to ensure resistance to damage and provide comfortability. *Microphone for phone calls and interactive learning lessons. *Folds flat for compact on-the-go travel experience, Hard Shell Carrying Case included for protection while on-the-go.
