For TCL 40 XL/XE/X/NxtPaper - OWS Wireless Ear-hook Bluetooth Earbuds, Open-Ear True Stereo Headphones with Charging Case & Hands-free Mic

Open-ear, non in-ear ear-hook design reduces the discomfort of in-ear or over-ear styles and helps keep the ear canal clean and hygienic while letting you hear ambient sound. This makes the earbuds safer for activities like running and jogging because you stay aware of your surroundings. The earbuds power on and pair automatically when removed from the charging case, including a voice prompt saying "pairing"; after the two buds pair with each other you can connect your phone via Bluetooth. Controls are touch-based for easy playback, track and call handling. Audio is delivered as HD stereo with stereo bass, supported by noise cancellation technology for clearer playback and calling. A built-in microphone enables hands-free calls. The compact charging case has a built-in battery and LED display and charges the earbuds automatically when they are placed inside. The mini portable 400mah charging case can recharge the earphones up to 5x. Each earbud provides independent volume and track controls so you can use either bud alone in independent mode. The headset is driven by an advanced chip for stable performance.
