I've been using these headphones for seven years.
They are my first headphones. I bought them because they are Sennheiser! Don't expect them to be Beyerdynamic. They don't have a very analytic sound but can be found in many studios because they sound very musical and cover a wide frequency range.

I have never regretted having bought them: nice looking product, pleasant to use, but some things disappointed me:
- I already replaced the cable three times because of a bad contact in the proprietary jack. On the other hand, I must say that I didn't treat them very carefully...
- The sound is musical but tiring in the long run. I find them too "closed." Especially because I use them loud and the leather gets really warm.
- After seven years of use, the leather became so warm that it seemed like it would melt. Perhaps because my hair was wet sometimes... It's not good for leather.
- Good quality transducers but it seems one of them doesn't work properly anymore. I would like more reliability...

I don't think I would buy them again. I would save more money and buy a premium product like the HD600 or a STAX.
In this price price range, I recommend the product but with velvet ear cups to avoid heating problems.
