LEKATO Wireless System WS-70. I used it only once at home. Operation has been confirmed. It gave the impression of being easy to use due to its low latency. I am selling it because I have no opportunity to use it. Power ON/OFF and pairing by long-pressing the button. Channel change by pressing the button once. Included: Charging cable (microB2 split, genuine) - Brand: LEKATO - Model: Receiver - Model: Transmitter - Model: WS-70 - System: Wireless System Thank you for viewing.
