Product Description

The i12 TWS Wireless Bluetooth Earphones provide an easy and affordable true-wireless listening experience. Their lightweight semi-in-ear shape is designed to rest naturally in the ears without silicone tips, making them comfortable for casual listening, phone calls and video streaming.

Bluetooth 5.0 supports a stable connection with compatible smartphones, tablets, laptops and other Bluetooth-enabled devices. After completing the first pairing, the earphones automatically reconnect to the previously connected device when removed from the charging case.

Built-in touch controls allow users to manage music, answer calls, change tracks, adjust volume and activate a compatible voice assistant. Each earphone includes an integrated microphone, allowing either side to be used independently for hands-free calls.

The rechargeable case stores, protects and charges both earphones between listening sessions. Common i12 models provide approximately 2–3 hours of music playback per charge, while the case supplies additional recharges when away from a power source. The available i12 TWS user guide confirms Bluetooth 5.0, touch controls, built-in microphones, automatic power-on and automatic pairing.
