For TCL ION Z/X Ear-Hook Open-Ear TWS Bluetooth Earphones — Over-the-Ear True Wireless Stereo Earbuds with Hands-Free Mic & 500mah Charging Case

Open-ear ear-hook design reduces the discomfort common with in-ear or bulky over-ear models and helps keep the ear canal clean and hygienic while letting you hear ambient sounds during playback. These over-the-ear earbuds are True Wireless Stereo (TWS) Bluetooth headphones built for comfortable, all-day wear. Auto power-on and pairing: remove the earbuds from the charging case and they will automatically power up and pair with each other, with a voice prompt saying "pairing". After the two earbuds link, connect them to your phone via Bluetooth as usual. Button controls: a single press on either earbud pauses or plays music and answers or ends calls. Left earbud — double-press to lower volume; triple-press to go to the previous track. Right earbud — double-press to raise volume. Sound and call quality: delivers HD stereo audio with strong bass and built-in noise cancellation technology to reduce background interference. Each earbud includes a microphone for clear hands-free calling. Charging case and battery: the compact charging case includes a built-in battery and LED display and will recharge the earbuds automatically when they are placed inside. The 500mah charging case can recharge the earphones up to 5x. Additional features: each earbud offers independent volume and track control so a single earbud can be used alone in independent mode. The set is driven by an advanced chip for stable performance.
