Comparatively - my Senn HD600s are 300 ohm and a sensitivity of 97 dB/mW.  I just tried my Senns out of my X5 at 100 volume and it is very, very loud. If the DJ1 are not isolating enough on the train - get yourself some decent IEMs.  And then turn the volume down.  Please take some advice from someone who has permanent tinnitus - be careful with your hearing - once it's damaged, it's often permanent.

 

As far as the X5 goes, mine can get a little warm from extended listening, but we're not talking about high heat here.  I'm wondering if it's a combo of the high ambient heat + the volume you're using?

It could have been... that time i also noticed some strange lines on the display going from left to right... as to about the volume, i understand what you are saying, i also have ie8, and they isolate even worse... i needed to do something on the train, 3 hours ride me standing, because there were no open seats... and i payed full ticket.... 

 

so... now x5 seems fine....

 

normally i listen on lowest volume 50-60 and highest 90-100 in quiet envoirment... i have a very very slight tinnitus after long listenning sessions, and this tinnitus dissapears after a time, and i i can only hear it when it is very very silent... and this is not because of what i am listening now, i was listening to live bands, in a 8 meters with 10 meters room. and i mean, the speakers were concert speakers and were set literally 1 meter from us, the crowd... also, the drummer did not needed a speaker, because the cymbals were hurting everyone's ears.... i have gone to only 1 concert without protection, and it was enough for me. i am wearing protection everytime i go to these. 

 

about the temperature, it might have been, again because of the ambient temperature, it had the leather jacket, and, a very high volume.... but stilll, it was very hot, and acting wierd...

 

Edit::: I tried hd650, and with x5 i needed the full 110 volume to think that it was good, about 80 volume for normal to quiet listening, and about a quarter of e12 potentiometre to think it was too loud.... strange, eh?....

Are you listening to classical or ...... ?

 

I have HD650 here too at the moment.  Normal modern recording (eg 3 Doors Down, Dire Straits etc) and 70/120 is almost too loud.  Just measured with a decibel meter, and it's showing 70-80dB.  Comfortable for me is around 60-65/120.  I would only turn it up for classical or recordings where the mastering is lower than today's average dB output.

 

I tried your 110/120, and it's averaging 85-95db with peaks at around 100dB.

 

Unless there is a huge difference with our HD650's or with our X5's (or maybe it's the music we're listening to) - I would prescribe caution.  Do you have a smart phone that you can utilise an SPL meter app? It's a good way to get a rough check.  Just point the phone's mics inside the cup, and take notice of the ave and peak outputs.

Actually another thought .... Are the EU Fiio X5 volume limited?
