Anker Soundcore Sleep A30

• Noise Reduction: Smart/adaptive ANC (up to ~30 dB reduction claimed) that adjusts to ear shape and fit, combined with strong passive isolation. Adaptive snore masking uses microphones in the charging case to detect and generate real-time masking sounds for snoring, pet noises, traffic, or appliance hum.
