Material quality:
everything breathes the beautiful quality, even the cable is perfect (beautiful, soft), it did a few months we are two and foam earphones is always like new.
Sound quality: its clear, deep, also a feast to watch TV well as our electronic piano or listening to music.
Remarks:
- The cord may seem a bit short for some: I prefer because as he never trainera the ground, and then you can always add a cord to extend
- There are no audio level setting on the cord: I prefer too.
No need to put more expensive!
