Under-Pillow Bone Conduction Sleep Speaker with Display, Extended Size Wireless Bluetooth White Noise Machine, 36 Built-in Sounds, 650mAh Battery, Auto Timer & TF Card Compatible, Ideal for Insomnia

《Two Ways To Play Bedtime Audio》Stream from a compatible Bluetooth phone when you want podcasts, audiobooks, music or ambient tracks, or use TF-card playback for an offline bedtime session. TF-card compatibility is built into the device, but the current evidence does not confirm that a memory card is included in the package. 《Extended Bone-Conduction Contact Area》The longer under-pillow body increases contact with the pillow so vibration can spread across a broader area. Place the speaker beneath the pillow and adjust its position and volume until the sound suits your setup. Pillow thickness, filling and placement can change the perceived loudness and resonance. 《36 Sounds Ready Without A Phone》Access built-in rain, water, wind, birds, fire and train-style audio when you prefer a simple screen-free routine. The expanded library supports bedtime, reading, meditation or quiet relaxation without requiring continuous phone streaming, internet access or recurring audio refills. 《Display And Timer For Night-Time Control》Check the sound mode, volume, timer and battery status directly on the screen. The visible controls reduce guesswork during a dark-room adjustment, while the timer lets you define a listening period rather than leaving playback running longer than intended. 《Rechargeable 650mah Format》A built-in 650mAh battery supports portable use around the home or while travelling. Recharge as needed and keep the device dry and uncovered beneath the pillow. This is an under-pillow speaker for personal audio and relaxation routines, not an in-ear device, smart-home speaker or medical sleep aid.
