TWS Ear-hook Bluetooth Earbuds for TCL 50 XE NXTPAPER 5G/Pro NxtPaper — Open-Ear Over-the-Ear True Wireless Stereo with Charging Case & Hands-free Mic

Open-ear, ear-hook design reduces the discomfort of in-ear or large over-ear models while keeping the ear canal clean and allowing ambient sound to be heard during playback. The earbuds feature automatic power-on and auto-pairing: remove them from the case to power them up and pair to each other with a voice prompt saying "pairing," then connect to your phone via Bluetooth. Physical button controls handle playback and calls — a single press plays/pauses music or answers/ends calls. Volume is adjusted by double-pressing: left earbud 2 clicks to lower volume, right earbud 2 clicks to raise volume. The left earbud supports 3 clicks for the previous track. HD stereo audio with noise cancellation delivers clear music and call quality, and an integrated microphone enables hands-free calling. Charging is managed by the included case: the earbuds charge automatically when seated in the case, which features a built-in battery and LED display. The listing references a 500mah charge case and also a mini portable 950mah charging case that can recharge the earphones up to 5x. Each earbud works independently with its own volume and track controls (independent mode), and the system is powered by an advanced chip to provide stereo bass and reliable wireless performance.
