AUDIO / T81
T81 Semi-in-ear Powerful-sound Wireless Earbuds
A light semi-in-ear fit with a fuller, more energetic sound.
The supplier-list S81 and image-catalog T81 are consolidated as T81. The former storefront lists an AB5656 chipset, Bluetooth 5.4, a Φ13 mm/25 Ω driver, 118±3 dB speaker sensitivity, semi-in-ear fit, music/call/standby figures, track, volume, redial, call and voice controls, two-device connection, black/white colors, USB Type-C charging, and a USB cable. Bluetooth marking, battery capacity, and runtime conflict across materials, so those values are not asserted and are confirmed by sales lot.
