I have a "anniversary model"; from what I can tell, it has a new wire that is more robust, in a "braid" similar to that of a G9X mouse (but it is thick and awful there), it is flexible and thin, and it has a very strong connection; I often forgot to put my headphones on my head before getting up. The brief wire is a pain. For convenience's sake, you can simply forget about them and sit for 15 hours, as was already indicated. 6 extra ear cushions purchased from Amazon. Within the mother, embedded. These ears are "on the edge" when listening to Realtek ALC892, as the volume control is set to 100% all the time and outside noises are hardly discernible. Of course, a standalone Hi-Fi amplifier with a microphone output is much more potent. I'm at a loss for words when it comes to sound alone because there is nothing to compare it to and I'm not really tempted, but at first I enjoyed it because new nuances were revealed and the bass was stronger.
