Thank you for viewing. I've only used it three times since opening it. It features high-quality sound, low noise, and a Type-C charging connector. Having played guitar for many decades, I perceive a slight delay, so please consider this carefully if you are sensitive to such things. The sound quality is good, and I don't notice any concerning noise. I think it's an affordable price for experiencing wireless sound easily. It supports simultaneous use of 4 channels. Thank you.
