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: Do not look at this if your wanting big base sound. this kind of gear is for people that want audio on how it was mixed. It will not wow you like from a concert hall that is shaking the floor. you will hear stuff in music you never could possibly hear from a ipod and headset. Also its only as good as the quality of audio you feed it.
Pros: Audio in this is amazing. Very flat and music sounds like it was intended. Both pieces of equipment looks awesome in my office.
Summary: The Sennheiser HD 800 (Factory Refurbished) headphones that I purchased and received looked brand new. I was overwhelmed with joy when I saw the like new condition of the headphone. Processing and shipping was very fast. The Sennheiser HD 800 (Factory Refurbished) are simply the "best headphones in the world." Crutchfield has the best price on the Sennheiser HD 800 (Factory Refurbished). An audiophile must buy!
Pros: Soundstage, depth, clarity, separation, openness, and realism.
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: I have had dozens of headphones love em . I had the 700s and talked myself into believing they were as good as the 800s. Then I found the hd800 on sale and went for it....OMG no comparison I am amazed at these cans . They sound incredible at low volumes They rock out when you crank them up .
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.
