This is the sleep mask with built-in wireless speakers that allow you to listen to music while falling asleep without disturbing others. The speakers connect to a smartphone or any Bluetooth device up to 50' away, enabling you to fall asleep to a preferred music collection. Three buttons on the side of the mask adjust the volume, select the next or previous song, and turn the unit on or off. The sleep mask is made from smooth microfiber lined with soft foam that is impervious to light and comfortable against the eyes. A microphone built into the unit’s control module enables you to answer incoming calls. The unit’s rechargeable battery provides up to six hours of playback after a 90 minute charge via the included microUSB cable. Imported. 12" L x 4" H x 2" D. (5 oz.)
