Sold in a beautiful quality box. Different pros: 1. Sound. He's the best I've heard. I recently bought bluetooth headphones from Sony for 15k, the sound is not good for hyperixes. 2. Earphone material and comfortable fit. I can wear glasses for hours. Ears do not sweat and do not hurt, no inconvenience. It is also good that the wire is very long, you can insert it into the back of the system unit and stretch it over the table, and you can still move away from the table with them. Different cons: 1. Microphone. Duplicate sounds. Many complain and I agree with them. 2. Volume control. I don’t touch it often (I often adjust it in Windows), but after 8 months, when the volume wheel is turned to the maximum, the right earpiece becomes quiet.
