I was using these with a Bluetooth connection for listening to music and video conferencing (microphone). There were no problems with the operation. The connection at the base of the left side is not complete and is broken. The ear cuffs have been replaced with aftermarket ones. There is also stickiness due to hydrolysis. The included accessories are only the coil cable and the USB charging cable. The manual and original box are not included. Shipping will be in a separate box with packing material. You can also use them wired if you use the included cable. The appeal is that you can use them both wirelessly and wired. Although there are no operational problems, please understand that these are practically junk items due to their poor condition and few accessories. I will not be lowering the price. Thank you for your consideration.
