Developed and made in Germany they offer an incredibly realistic natural sound field and also stand apart by the extraordinary attention given to every detail of their design.

## Questions & Answers

**Q: Will this make me better at Fortnite?**
A: Yes! Unironically, yes. These headphones have the widest sound stage and detail retrieval of any close back headphone. This quite literally and unironically makes them the best gaming headphones ever made.

**Q: Is this really closed back headphone? If I put on no one can hear what I am listening?**
A: I tried them and you can still hear them like open backed headphone. I sent them back and bought the 800S instead which sound just as good for a lot less

**Q: can you use the cable of the hd800 (s) for these ?**
A: Yes, they share the same adapters.

**Q: Would these headphones be suitable for listening to classical music and not letting out sounds that bother people in the same room?
Thankful.**
A: Most audiophile reviewers say these headphones go best with classical, Jazz and electronic music.  I personal use them for everything and they sound fantastic.  You'll need a good amp to power them, but even on high volumes there is minimal noise leakage.  Depending on the seal around your head/face, the noise can be heard outside.  Although I've never heard a complaint that it was too loud for a person in the same room.  Most time they never heard anything, but I don't play music loud.
