The Rohm effectively blocks out disruptive noises to enhance sleep and focus. It offers three soothing sound options - bright white noise, deep white noise, and gentle surf - with adjustable volume. This compact and lightweight device can easily be carried in a bag or backpack and includes a lanyard for convenience. It can be operated continuously on a single charge using the provided USB cable. With its noise-masking capabilities, it serves as a natural sleep aid, promotes office privacy, soothes babies and kids, calms sound-sensitive dogs, alleviates tinnitus, and provides relaxation in noisy environments. It is important to turn off and unplug the device every 14 days when used portably.
