Most headphones would thereby already gone on it. Extremely positive is the shelf life of the cable. I stayed already hanging countless times anywhere and have strong ripped the cable, sums up every other headphone cable is torn, not so when PortaPro.
The only significant wear after 1.5 years the foam poster. This I have to replace in six months time.
Also positive is the lifetime warranty on the headphones (have at least my such, I do not know if it's still there).
The sound is very good for my taste. In my opinion, a very good headphones for its price.

The above review is the Porta Pro I bought about 3 years ago.
My 2nd newer model I had a few months due to cable breakage (now the cable is much thinner and the jack connector no longer bent but small and straight) Send to Amazon back.
This deterioration is a pity. Have however now my 3rd Porta Pro ordered. Let's see how to make the current batch.

Also at the 3rd Porta Pro - bought 9.2010 there was already after half a year a cable break! So a scrap.
Got my rating of 5 is changed to 3 stars. If the cable for 6 months now already 2x breaks that is a massive shortage.

Update 2.2015: Use my last bought Porta Pro continues to be. The design is ansich Hammer and extremely robust (with Außnahme the cable). The sound is anyway super.
Due to the 10-year warranty I will send the headphones always, if something breaks. Finally, it was the cable up to the headphones. Connect the cable to the jack now seems to be improving, it holds quite a while.
With regard to the guarantee, it is probably so that the German importer, the Sound Magic GmbH is probably only responsible for other traders, but not for Amazon. As the warranty repair after more than 2 years running on Amazon I do not know. Just try! 10 year warranty 10 year warranty!
Still BUY recommendation.
