TWS Ear-hook Bluetooth Earbuds for Nokia XR21, T21, X100 — Over‑Ear True Wireless Stereo with 500mah Charging Case & Hands‑free Mic

Open-ear ear-hook design avoids the discomfort of in-ear or fully over-ear styles, keeps the ear canal hygienic and still lets you hear ambient sounds while listening. The earbuds come with a mini, portable 500mah charging case that has a built-in battery and LED display; placing the earbuds inside starts charging automatically and the case can recharge the earphones up to 5x. Take the buds out of the case and they power on and pair with each other automatically — you’ll hear a voice prompt saying "pairing" — then connect to your phone via Bluetooth. Physical button controls: single press to play/pause music or answer/end calls; left earbud double-press to lower volume, right earbud double-press to raise volume; left earbud triple-press for previous track. Each earbud supports independent volume and track control, so one bud can be used alone in independent mode. Sound is delivered in HD stereo with noise cancellation technology for clear audio and call quality, and a built-in microphone enables hands-free calling. Equipped with an advanced chip for reliable performance and seamless operation.
