Bone conduction under-pillow sleep speaker, Bluetooth 5.3 low latency, TF card dual-mode LED digital display, bedtime music and white noise player (black)

Bone conduction sound transmission: Placed under the pillow, sound is transmitted through vibration, but not externally, so the person next to you can barely hear it, minimizing disturbance to your partner's rest.

Dual playback modes: Bluetooth 5.3 (low latency, 10-meter transmission range, 99% device compatibility) + TF card direct reading, allowing playback without a phone; the TF card can also be used as a USB flash drive for file transfer.

Sleep aid design: Supports timer shutdown (5-minute increments, up to 195 minutes), eliminating the need to get up at night for operation, ensuring a peaceful night's sleep.

Visual display: LED display shows real-time remaining battery power and operating status, providing a clear overview of usage.

Battery: 400mAh lithium battery with protection board.

Charging: Type-C interface, operating voltage 3.1V-4.2V, safe and stable.

Solves the pain points of traditional headphones such as ear discomfort and noisy external speakers, suitable for listening to music, white noise, and audiobooks before bed.
