Ear-hook TWS Bluetooth Earbuds for Samsung Galaxy A71 5G/A51/A21/A11 - Over-the-Ear True Wireless Stereo Headphones with Charging Case & Hands-free Mic

Open-ear ear-hook design avoids the discomfort of in-ear or over-ear styles, keeps the ear canal clean and lets you hear ambient sounds while listening. These wireless earphones support TWS true wireless stereo and include auto power-on and auto-pairing: remove the earbuds from the case and they will turn on, pair with each other and announce "pairing" before you connect them to your phone. Button controls manage playback and calls — single press to play/pause or answer/hang up — with additional shortcuts: left earbud double-press to lower volume, right earbud double-press to raise volume, and left earbud triple-press for the previous track. A built-in microphone plus noise cancellation technology deliver clear calling, while HD stereo audio and stereo bass provide high-quality music playback. Each earbud has independent volume and track controls and can be used alone in independent (single-ear) mode. The earbuds charge automatically when returned to the case; the listing references a 500mah charge case. The charging case also features a built-in battery and LED display, and the product is described as equipped with a mini portable 950mah charging case that can recharge the earphones up to 5x. Powered by an advanced chip for stable wireless performance.
