These are also the most comfortable and best sounding cans I have owned (I also own the steelseries arctis 4 and a pair of sonys extra bass over ears). HOWEVER does not fit my 2019. The build quality of the feet seem below average, cheap plastic. Some of the charts that contain small fonts are almost impossible to read on a device like a phone or iPad. I tried these on many devices with many resets and other tricks but nothing worked for me. Also find the foam roller exercises ease out my painful shoulders n neck after a work day sa in front of a PC. I did manage to hang on my pantry door, but it isnt as pretty as I hoped if the shelves werent so bent out of shape. The headphones themselves are the 4 conductor 3. Seller sent replacement for one jar that was broken during transport immediately. I recommend these cute slides and will probably purchase another color soon.
