These new Bluetooth products maintain ISOtunes' SafeMax Technology while introducing enhancements in design and functionality. Unlike most headphones, all ISOtunes headphones limit the volume to 85 decibels (dB) and offer a noise reduction rating (NRR) between 22 and 29 dB, making them OSHA and NIOSH compliant.
