## Description

The new audiophile standard for closed-back headphones for audiophiles there wasn't any doubt: When it came to circumaural headphones the very best sound required an open back design. This axiom has now been rendered obsolete by the youngest member of the Sennheiser Audiophile Range: The closed dynamic HD 820 employ an innovative technology that makes them sound breathtakingly transparent and natural. 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. Their soft comfortable microfiber ear pads are hand crafted providing excellent attenuation of ambient noise while the robust metal headband includes an inner damping element. Get ready for an unparalleled listening experience. Into the great wide open vivid wide transparent natural. The sound field of the HD 820 is wide open. Which is not what you would expect at all from closed circumaural headphones. With the HD 820 you can explore and rediscover your music in absolute reference-class quality without intruding on the aural comfort zone of others. Thus the HD 820 not only open up the sound field but also new places and opportunities for you to enjoy your music. The Technology of Transparency The breakthrough transparent performance of the HD 820 has been achieved through a special innovation: Their legendary Sennheiser Ring Radiator transducers are fitted with unique glass covers.

## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ In one word - Superb
*by L***R on 3 October 2020*

Bought these in a package together with Sennheiser DAC HDV820 and all I can say is WOW!!!The difference between the reproduction on these and say my Sony MDR-1000X is like chalk and cheeseEvery familiar track is like a whole new experience- the openness and clarity is awesomeSome say they are a little lacking in bass but not for me.I have only played a dozen or so tracks from my pop collection so I will be interested to here how well they reproduce my jazz, blues, classical and opera collections.Money well spent especially if you travel a lot as I do and cannot always have my home hi FI set up to listen to
