AUDIO TECHNICA ATH-AD900X Headphones "Class A" and "Best Buy" rated

The Audio Technica ADH-AD900X has been internationally established
as one of the best values in high resolution headphones. It won multiple awards from
some of the most prestigious audio periodicals for excellence in
sound reproduction. The 900X featured minor upgrades to the original
multiple award-winning ATH-AD900. These improvements include a slight
inboard angle to the drivers which improve soundstaging and
reportedly have better tonal and instrumental timbre accuracy, more
air in the high frequencies and eliminated the very slight trace of
sibilence in the vocal range of the ATH-AD900. The ADH-AD900x is
extraordinarily accurate in musical reproduction and possesses a
minor degree of magic in the reproduction of female voices. These
really are a milestone in headphone performance in this price range
and easily one of the best ever made by A/T.

According to Audio Technica the ATH-AD900X is...

“...Designed to deliver extraordinary sound quality to satisfy the most
discriminating listeners, the ATH-AD900x is ideal for music lovers
who prefer the spacious quality of open-back headphones that combine
involving sound with long-wearing comfort.” 

"The ATH-AD900x features large 53 mm drivers exclusively designed for the
headphones, with rare-earth magnets and Audio-Technica’s
copper-clad aluminum-wire (CCAW) voice coil technology for superior
audio reproduction with an extremely wide 5 Hz – 35,000 Hz
frequency response. The ATH-AD900x offers an immersive listening
experience with clear, natural vocal and instrumental reproduction, a
smooth tonal balance, precise imaging and superlative dynamic
range.” 

“The headphones offer a uniquely comfortable fit thanks to their
generously cushioned ear pads, lightweight honeycomb aluminum casing
and exclusive 3D Wing Support Housing, which adjusts itself perfectly
to each wearer...”

Some of the industry critiques of the ATH-AD900X are as follows:

HiFi Choice “Best Headphone Award” Winner.

“...Because competition in the headphone market is so tough, it takes a special
pair of cans to win this award – and Audio-Technica’s ‘A900X is
precisely this. It sounds clean, open and smooth with oodles of
detail and insight – and you’ll want to listen all day and all of
the night thanks to the high level of comfort, courtesy of a clever
headband design. Build  is excellent, too. A worthy winner...”

Sound and Vision Magazine called them “...one of the world’s best
bargains in an audiophile headphone.”

Stereophile Class “A” rated Audio-Technica ATH-AD900: $299.95 $$$ 

“...The ATH-AD900 has the same basic look and design as the less expensive
ATH-AD700, but offer significantly better build quality. They had a
nuanced, natural sound, with outstanding low-level detail and
exquisite tonality, said ST. The best ‘phones he’s heard for the
money, but they made casual listening almost impossible. “Unless
you’re a boom-boom bass freak and a total philistine, get a pair,”
he said, adding that “the bass is superbly defined, however, making
many other headphones sound bloated and overblown.”

...By the way, Stereophile rated the ATH-AD900 on a par with competetive
headphones priced at $1,500(!).

I bought these brand new and am the original owner. They were used for
a studio recording project which has been completed. They were slowly
and properly broken in for 100 hours before they were used in the
studio for a recording project that lasted 10 days. The headphones may be considered in mint (9.9) condition. They were never abused or mistreated and were always stored in their factory box, which was extensively modified by removing much of the inner panel
behind the box cover for easier access (the box therefore should not be considered as “factory condition)”. The box will be supplied as well as the 3.5mm to 1/4” adapter, original packing, factory paperwork and manual. Price is a great value at $99. Buyer to pay $14 for shipping w/in the ConUS (only). I will absorb Paypal charges.

These really are great headphones; dynamic, articulate and very faithful to
the recording. They provide an exceptionally satisfactory auditory
experience that exceeds the performance of headphones that cost many
times their price.
