The 3M WorkTunes Wireless Hearing Protector with Bluetooth technology helps you protect your hearing while enjoying your favorite music, podcast, audio book or radio station. Equipped with Bluetooth Technology, these protective headphones allow you to stream the entertainment of your choice from your smartphone, tablet or other mobile device, while Safe Volume Control Technology self-adjusts to ensure you're listening at a safe volume level throughout your work day.

All the controls are on the headset - so there's no need to be tethered by a cord. The soft ear cushions are designed with comfort in mind, and the flexible headband with ventilation improves comfort when worn with a hat.
