Key Features

• Ultra-Comfortable Design for Side Sleepers – The Sleep A20 features a compact, low-profile design with soft materials that reduce pressure on the ears, making it comfortable to wear throughout the night, even while sleeping on your side.
• 4-Point Noise Masking System – Designed to minimize sleep disturbances, the earbuds combine passive noise blocking, Twin-Seal ear tips, sound masking audio, and Smart Volume Control to help reduce the impact of surrounding noises.
