Ozlo Sleepbuds HEADPHONES
Its biometric sleep sensing automatically switches from Bluetooth LE streaming to noise-masking when you fall asleep, a feature that sets it apart from standard earbuds. The ultra-slim, soft silicone design sits flush in the ear, making it one of the few options genuinely comfortable for side sleepers throughout the night. These are best for light sleepers and side sleepers who need to block snoring or street noise without relying on medication.
