This is the Yamaha wireless headphones YH-WL500. I am selling these because I haven't had much opportunity to use them since I bought them. I purchased them on Amazon on March 20, 2025. I have confirmed that they work, and all accessories are included. I am a non-smoker, but I do have a dog indoors. Please understand that these are used items. Due to the nature of wireless devices, some people may be concerned about interference with other devices, but I used them in conjunction with a BOSS WL-60 without any problems. I plan to wrap the original box in air cap for shipping. Please consider the listed price. Also, I do not offer dedicated sales. Thank you.
