The Anker Soundcore Sleep A20 are true wireless earbuds engineered specifically for use during sleep. They employ a passive noise-canceling design that uses Twin-Seal ear tips to physically block ambient sounds that may disrupt rest. The low-profile construction is intended to sit flush within the ear, providing a comfortable fit for individuals who sleep on their side. Audio is delivered via a Bluetooth 5.3 connection, offering a wireless range of up to 10 meters and support for both AAC and SBC codecs.
A single charge delivers up to 14 hours of continuous audio playback. The included charging case extends the total operational time to 80 hours, reducing the frequency of recharging. The entire system recharges in approximately 1.5 hours through its USB-C port. An IPX4 rating indicates resistance to sweat and light moisture, while on-device tap controls allow for function management without a separate device. The companion app for Android and iOS provides access to additional settings and audio options.
