TWS Open-Ear Ear-Hook Bluetooth Earbuds for Samsung Galaxy Z Flip5/Flip4/Flip 3 5G — True Wireless Stereo with Charging Case, Hands-Free Over-the-Ear Design

Open-ear ear-hook design avoids the discomfort of in-ear or fully over-ear headphones and helps keep the ear canal clean while allowing ambient sound to be heard during playback. These TWS earbuds support auto power-on and auto pairing: when you remove them from the charging case they power on and pair with each other automatically, with a voice prompt saying "pairing"; once the two earbuds pair, connect them to your phone via Bluetooth. Physical button controls handle playback and calls — a single press will play or pause music and will answer or end a call. Volume is adjusted with two-click presses (left earbud 2 clicks to lower volume, right earbud 2 clicks to raise volume). Left headphone 3 clicks for last song. The earbuds include a built-in microphone and noise cancellation technology to deliver HD stereo audio and clear call quality. The charging case features a built-in battery and LED display and charges the earbuds automatically when they are placed inside. The listing mentions a 500mah charge case. It also references a mini portable 950mah charging case that can recharge the earphones up to 5x. Each earbud offers independent volume and track controls so you can use one earbud alone in independent mode; the system is powered by an advanced chip for stable wireless performance.
