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.
Some very serious soundages from this crown of a headphone
6 January 2014
Summary: I'm new to this niche market. I spoke to 3 advisers in the past month since my purchase. Each was impartial, objective, patient, knowledgeable and ultimately correct . I ended up purchasing the AK100 and the SennHD650, SennHD800 & Grado GS100i- I chose to keep just the 800's. Superior in sound, although the Grados I felt were much more comfortable (& gorgeous) , they only lacked somewhat in tone when compared to the Senn 800's.
Pros: My enjoyment for listening to music has just become exponentially more enjoyable. Unmatched in customer service and folks who offer excellent opinions in earnest. Quick shipping, easy to return items. Just a well run outfit it seems from all corners
Cons: Slightly heavier than the Grados, & Senn does not offer a short cable if you want to take these poratble, you must go to a custom shop for that.
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: I would rate this HP 5 star purely based on the sound quality. Coming from HD650, sound quality is noticeably better but highs are a bit too harsh for my taste. Build quality wise, mine came with some minor scratches upon arrival. They are refurbished, can't complain. My wasn't "as new" as others have reported. I guess that's my luck. I have no intention sell them anyway so scratch or no scratch doesn't really matter to me.
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.
