The ISOtunes Air Defender AM/FM BT is a Bluetooth earmuff with a built-in AM/FM radio, made for loud workplaces where you want music, calls or radio while blocking noise. It carries a 25 dB noise reduction rating and SafeMax limits output to 85 dB. ISOtunes says it is over 20% lighter than its other earmuffs and rates battery life up to 50 hours. It suits workshop, landscaping and machinery users who want one headset for protection and audio; rivals in this class usually drop the radio or the lighter build.
