I noticed that the Tux5 cable felt a little heavy. I took the heatshrink off as it was creating a lot of friction and pulling the nozzle against the top of the external auditory meatus. Really painful after an hour. Much more comfortable without it. I did weigh it... it weighs 40g versus my Ares 8W which is 36g. Not much, but a definite difference. The Ares is more comfortable to wear and has a different sound - drier, with a larger soundstage but still very impactful.
