Beyerdynamic T90: High-end cans with remarkably accurate sound. Extremely wonderful sounding headphone, in perfect working condition, very little used as I prioritised my other headphones. Was protected with a plastic foil at the beginning, no smoking environement. 

Comes with original box and all the accessories. 

Could consider posting it internationally but please, ask for a quote as the postage differs from country to country and the amount in the description is for European Union only, thanks.

"The Beyer T90 are superb headphones, especially if you want detailed, open, uncolored sound with tight, natural bass.

If the T90 are too expensive, get them anyway! Unlike consumer electronics like a flat-screen TV or digital camera that you'll want to throw away in 5 years or less, invest your money in headphones or speakers and you'll still be enjoying them decades from now. I still use my original set of Beyer DT990s that I bought in 1986. They seemed expensive then, but the price has long been forgotten while their quality is remembered every day.

Headphones don't wear out or age. So long as you don't abuse them too much, they ought to outlive you. Never get cheap with headphones or speakers; they don't become obsolete as do electronics; these are completely passive transducers.The T90 overall has a very good detail retrieval, maybe not at the same level of the Sennheiser HD800 but one of the best I’ve heard so far. Left-right balance and 3-dimensionality are simply incredible, just like the huge sound stage. The presentation in general is rather airy and there is a lot of space between the instruments. The T90 is a tight sounding headphone that’s not coloring the sound, well maybe just very slightly but you get a very clear and realistic presentation no matter what genre you’re listening to. The T90’s bass is very tight and has reasonable impact/body. Bass detail and layering are very good and bass goes really deep. T90 is strong with everything, I really mean that the T90 is strong with all musical genres, I’ve even spent quite a lot of time with it watching movies and I couldn’t find a genre that doesn’t match with this headphone."

Conclusion: The Beyerdynamic T90 is expensive, but for well-heeled audiophiles the price will seem reasonable. I know of no other less-expensive headphone that can match the T-90's combination of comfort, sound, and build quality. Perhaps the biggest downside to the T90 is that it's not well-suited to portable use, but few full-size, audiophile-oriented headphones are. The T90 is best savored at home, plugged into a high-quality headphone amplifier or AV receiver.
