- For how long have you been using it?
I had these for about 8 or 9 years.

- What thing do you like most/least about it?
That i sold them.

- Did you try many other models before getting this one?
No, or i would have got the others.

- What is your opinion about the value for the price?
Ludicrous. Yes, the bad way.

- Knowing what you know now, would you make the same choice?...
Obviously not.

Why...i hear you say!
These are closed headphones, that's good, they don't leak tooo much.
But they are hot, extremely uncomfortable after a while...(painful).
And they are very bassy. There is strictly no point trying to make anything sound right with these on unless you are totally used to listening to everything on these...
They are neither clear nor detailed enough...quite frankly i went on using them because i had not others. But you can't really do anything with them. They're a reference? Oh yeah? Well so are the 7506's and they're nothing you can do with those either...

They were 750 Francs at the time (£75), ie 115 euros, would i pay that again? No way.

Overpriced and overrated. Money back, please.
