I use these headphones for 7 years now.
I bought this headset, my first, because Sennheiser, Sennheiser is what. We can not ask him to be a Beyer. So it is not particularly analytical, it has no place in gold in the home studio but it is very musical and covers a large frequency band.
At the time, I was young (12 years), and I had really broken the piggy bank in order to have the best of all the headphones that I compared.
I have not really regretted it, because it is fun and enjoyable, but some points I was disappointed.
- I had to change three times the cable, due to a loose connection in the jack 2.5 owner. Well I must say that abusing bcp also ...
- The headphone is musical but using the long run. I find it quite "airy". Especially me who listens hard, it heats with leather
- Just after 7 years of use the leather is so heated that looks like it has melted in some places. Some people have had this? I think it's because on some occasions I had wet hair with the headphones on, thus forcing the leather not like it.
- The HP in are good, but I feel that there is one that has dropped. Would have to be more reliable ...

So no I do not think I would do this choice, I would wait longer and I'll buy a hat crazy, like the HD 600 or STAX.
If not in the same price range I recommend the model just above ear with velvet, it is not the same problems as the leather (heated & Co.)
