TWS wireless earphones with charging station. Perfect for listening to music and making calls. Placed in a charging case, you can quickly replenish the battery so that you can enjoy your favorite music continuously. The perfect adherence to the ear allows you to use the headset throughout the day, without pain or discomfort. This is due to its low weight: a single earpiece weighs only 4 g, size and ergonomic shape. Though the earphones are small, the diameter of the speaker is 13mm, which makes them transmit clear, deep sounds. MEMS system - modern technology eliminating noises that could disturb the course of a telephone conversation, ensures comfortable use. Charge briefly, use for long. The earphones consume very little power. When fully charged, batteries can work continuously for up to 4 hours. If you use them together with the charging case, the time is 6 times longer. Decide freely whether you use one or two earphones at the same time. The built-in mic allows you to talk - conveniently and hands-free. The earphones are very sensitive - just touch them and give the command. This way you can control your gadget: start or stop playback, manage incoming calls, turn on the voice assistant.
