Excerpt: You need the right system for these headphone ,i am useing a naim cdx2 player and i have an atlas mavros rca cable going into a lehmann audio linear headphone amp, and i did not change the stock cable on the HD800 but if i do i will consider the cardus clear because these are more like speaker cables which will benifit the HD800 because of the 56m drivers,The sound from this setup in simply stunning.
Summary: I seldom write reviews for any product I purchase but these headphones are worth the price. Great sound quality and dynamics. Build quality is good. I have A number of headphones at home and these are my go to cans.
Summary: State of the art headphones with a smooth and neutral sound character. If you are a "basehead" these phones are not for you. However, if you desire a natural and uncolored presentation with a holographic sound stage this is THE headphone. A bit too much plastic for me but otherwise well built and sturdy. Very comfortable for long listening sessions. Highly recommended.
Pros: Neutral sound character with W-I-D-E soundstage
Cons: Somewhat laid-back bass character but natural in character.
Summary: Sound quality and build quality are first rate and as a refurb they look brand new. Also included were the box and manual . No regrets with this purchase, compared to a Beyerdynamic T1 the HD800 has better imaging, soundstage and discrete imaging. The bass and comfort are not at the level of the Tesla T1. These HP's sound better with proper amp and Dac I am using a Meier Classic Corda Amp/Daccord combo. Even with a portable ALO Audio MKll they sound impactful.
Pros: Excellent HP in the upper most tier of top headphones. The best headphone I have ever heard with acoustic and classic music.
Cons: The headphones are not closed, so expect leakage if in a crowd.
Summary: This is my first set of headphones over $1,000 nor have I heard everything in this price range, so take it with a grain of salt. I bought the refurbished version and it is indistinguishable from new. Very pleased with the build quality, appearance and comfort. Using mainly 96k/24b FLAC files, these are easily the best sounding headphones I have ever heard. The sound is 3D and extremely detailed.
Pros: Sound quality - Sound stage/detail/transients, Build quality, Refurbished version looks like new, Comfort, Crutchfield's incredible customer service
Cons: You'll probably spend more on support equipment than you originally intended.
Summary: After doing a major audio electronics upgrade, auditioned a number of "over the ear" headphones and picked up the HD800s. Besides having superb detail, great bass (better than any other headphone I've auditioned), excellent stereo imagery, crisp highs and great "attack", these cans are easy to drive and just don't "run out of gas", even at high volumes.
Pros: Superb sound quality, easy to drive, very comfortable.
Excerpt: Packaged to perfection. It lives up to the hype. First pair of headphones that I actually do not want to remove. I coupled this purchase with a portable amp. Makes the mids and lows glow like I have never heard. Highs are easy on the ears.
Summary: Great headphones, one of the best out there. I did a search through all internet sites and found that Crutchfield sells these, a bit surprise. These were refurbished but they looked brand new to me; the only thing 'not new' was that the opening flap on the box was missing a tongue. So get these guys, at a discount for a blemish on a box! With a genuine two-year Sennheiser warranty, can't go wrong with this deal .
Pros: Price: high (as cons) but good deal with this refurbished discount. Super comfortable. I have the Denon Dx000 series 'phones and the comfort ability level is similar.
Cons: Do realize that these are open-air so little to no sound isolation in or out. Require delicate setup to sound good (these require a separate headphone amplifier). I power mine with a WA6SE amp which is not cheap. Be prepared to hurt your wallet, but will worth the effort!
