Yes. I thought could be a problem so i also ordered a balanced cable. I been using only the 2.5mm Output at 50-80%. I think i have to get used to them. have had the m50x for long time. Probably i was expecting something similar when i went from shitty stereo school/home desktop speakers to a mid-end equipment. or $15 in-ears to m50x. but most noticeable difference was i can't enjoy that cheap equipment as i used to do hahaha.
