J15U White Noise Machine — 10 Natural Sounds, USB‑Rechargeable Sleep Aid

Soothing sounds for sleep and focus

Choose from 10 natural sounds — white noise, ocean waves, birds, heartbeat, clock, crickets, running water and three lullabies — to mask distractions and support baby care, naps or focused work. It’s quick to switch between sounds so you can find what helps you relax or concentrate.

Smart timers and noise detection

Play continuously or set the automatic shutdown timer to 15, 30 or 60 minutes, with green/blue/red LEDs showing the chosen setting. Hold the Auto button for 2 seconds to run a 10‑second noise detection test; if ambient noise is detected the unit will play for 15 minutes then cycle, with an effective range of about 6–10 m.

USB rechargeable and travel‑ready

USB powered (DC 5V, 1A) with a 300mAh battery giving up to 23 hours’ use and a 1W power draw. The compact 8 × 9.3 cm plastic and silicone body fits easily in a bag; package includes the host, micro charging cable, user manual and lanyard. Please allow 0–1 cm measurement variation and minor colour differences due to screen settings.
