Thank you for viewing. I am selling one of the two I purchased for work, as I didn't use it. I mainly use it for music and meetings, and I have no problems with lag, noise, or microphone performance. I also like the operability, as it's easy to use with few button operations like taps and slides. If you're not using professional equipment and just for everyday use, I think this is a good choice among wireless headphones. The following is a copy from the official website.
