O1O Ear-hook TWS Bluetooth Earbuds for Samsung Galaxy Z Fold5/Flip5 — Open‑Ear Over‑Ear Wireless Headphones with Charging Case

Open‑ear ear-hook design avoids the discomfort of in-ear or fully over‑ear phones, keeps the ear canal clean and lets you hear ambient sound while listening. Model O1O supports True Wireless Stereo (TWS) and is compatible with Samsung Galaxy Z Fold5/Flip5. Audio is delivered as HD stereo with noise cancellation technology and a built-in microphone for clear calls. The earbuds use button controls: single press to play/pause music or answer/end calls; left ear 2 clicks lowers volume, right ear 2 clicks raises volume; left ear 3 clicks goes to the previous track. Each earbud has independent volume and track controls so you can use one bud alone in independent mode. Auto pairing and wireless connection are supported — removing the earbuds from the charging case powers them on and they automatically pair with each other (voice prompt: "pairing"); once the two earbuds pair, connect your phone via Bluetooth. The charging case contains a built-in battery and an LED display and will recharge the earbuds automatically when they are docked. This listing notes a 500mah charge case included with the wireless earbuds. The product is also described as equipped with a mini portable 950mah charging case that can recharge the earphones up to 5x. Advanced chip technology is used to improve performance and connection stability.
