Bluetooth 5.0 Sleep Mask With Speakers

A blackout sleep mask with thin speakers sewn into the padded band over each ear, wired to a Bluetooth 5.0 connection instead of earbuds that dig in while lying on your side. It handles full duplex calls, so a phone call can be answered without pulling the mask off, and the wireless range holds up without dropouts to about 10 meters, plenty for a phone left across the room. Talk time is rated at 15 hours, standby stretches out to 180 days between charges, and the internal battery is a modest 150mAh, charged at 5V through a standard cable. No fabric name is given here. It comes in black or dark blue, sold as a single mask or a two-pack. Side sleepers get the most benefit here, since the flat speaker design avoids the bulk of standard headphones pressing into a pillow.
