Easy Connection: Simply connect the transmitter to your TV's USB port and earphone jack. It also uses the 2.5GHz frequency band, which minimizes video and audio lag, allowing you to enjoy a stress-free TV viewing experience. [Easy Operation] The speaker has three buttons for easy operation: power, volume up, and volume down. The buttons are large and easy to press, making it easy for anyone to use. [Long-lasting use] The speaker itself uses a lithium-ion battery, which allows for approximately 20 hours of continuous use on a single full charge, eliminating the need for frequent charging. [Waterproof] The speaker is waterproof (IPX4 equivalent) to protect the inside from splashes of water. Especially in the kitchen, where noise from the ventilation fan and cooking can be a problem, you can use it with peace of mind even if it's difficult to hear the TV.
