it is too tight and after using it for 2 months it not longer works in the left ear and sounds like right ear is on the way out.

These can be a little tight on the ears (unless you have super tiny ears that can fit inside the cups)

They are tight and the cans are smaller than most Sennheisers, and they can cause your ears to become sore after a couple hours of use, but after you get used to them and break them in they are not so bad.

Had them for 2 months and now the right ear piece is silent.

I forget to mention the headphones 'break'(flip-up from the Right ear so you can keep control of Live sounds if you wish)

I don't typically use them continuously for more than a couple hours at a time because my ears get sore after that long.

Soon after, the right ear cup stopped producing sound

They're also very uncomfortable and tight around the ears, so much so that my ears are sore right now

Right ear cup broke within a year

So, you can put the earpeace on, and then twist the headphones accordinly to expose your right ear to the booth music.

Also after wearing them for 3-4 hours they can start to irritate your ears

Hurt my ears after only 15 minutes

where do i start... as another reviewer had pointed out, these headphones hurt -- a lot -- as my ears and temples felt like somebody had cinched a plastic clamp around my head

The sound in the right ear is gone unless i hold the cord a certain way.

Although they're not designed as "noise-cancelling", they isolate your ears very well

Broke after about 3 weeks of pretty light use, audio stopped coming through the left ear

The rotatable right ear cup makes one-ear on-the-fly monitoring easy• Gold plated jacks for superior sound quality• Screw-on 8.5mm jack• Sleek and sturdy, it even comes with it's own carrying bagNEUTRALS:• If you are a bass lover, be prepared to be disappointed

and it feels like my ears have been pushed half-way through my skull

I've tried all kinds of ways of putting these on my head, but ended up with sore ears after one six-hour session (with breaks, of course)

Although they're not designed as "noise-cancelling", they isolate your ears very well

but yeah, these REALLY hug your head, if you wear glasses these are right out because they will give you intense ear pain, ultimately going to be returning these after I bought the HD 449 and HD 280 PRO to try out, both of which go completely around the ear and are far more comfortable.

Moreover since I wear glasses, my ear hurt after sometime since these headphones press strongly against my ears

so, it might hurt your ears after few hours of using it.
