seem pretty good. they are super comfy, work from much distance and their battery seems to last. Can't say anything about the sound, since they seem all the same to me and ql directional sound is famously crap anyway.
JBL E50BT are so fucking loud maaaaaan! Dat BASS!
And sound quality is also great.
If ear cups will be a bit bigger then it will be best choice.
ofc I don't use them at PC. Only outdoors. At PC wired ones is comfortable for me.
