USAMS Bluetooth 5.0 TWS SYseries SY02 wireless headphones blue/blue BHUSY02

USAMS SY02 TWS Bluetooth wireless headset is a combination of convenience of use with a great design. Thanks to the use of tri-band tone equalization, the sound from the headphones is clearer and free of noise. Small and light, they will accompany you everywhere - at work, while exercising or while driving a car. Headphones with a built-in microphone use the Bluetooth 5.0 + EDR / BDR / BLE standard. The set also includes a dedicated case that works like a powerbank.
