Ear-Hook TWS Bluetooth Earbuds for Nokia XR20/XR21 — Over-Ear True Wireless Stereo with 500mah Charging Case & Hands-free Mic

Open-ear ear-hook design prevents the discomfort of traditional in-ear or over-ear models, keeps the ear canal clean and allows you to hear surrounding sounds while enjoying music. Remove the earbuds from the 500mah charging case and they power on and automatically pair to each other — a voice prompt will announce "pairing". Once the two earbuds are paired, connect your cellphone to them via Bluetooth. Physical button controls: 1 click to play/pause music or to answer/end a call; left earbud 2 clicks to decrease volume, right earbud 2 clicks to increase volume; left earbud 3 clicks to go to the previous track. Audio is delivered in HD stereo with rich bass and noise cancellation technology for clear playback and calling. A built-in microphone provides hands-free calling. The compact charging case features a built-in battery and led display; earbuds begin charging as soon as they are placed inside. This mini, portable 500mah case can recharge the earphones up to 5x. Each earbud supports independent volume and track control so one can be used alone in independent mode. Equipped with an advanced chip for reliable performance.
