Audio-Technica A900 modifications

March 8th, 2010 - 2:36 am | 9 Comments | Audio, Design, Industrial, Modifications, Projects

A few months ago after much reviewing and research I purchased an imported set of Audio-Technica A900 cans from Japan for the (depending on your background, high) price of $200 USD.  These are an extremely well valued “mid-fi” solution that can be powered by almost any source. They are physically massive and have a fantastic sound-stage with surprisingly deep and punchy bass. From photos you might assume the blue casing is plastic, but it’s actually anodized aluminum, a pleasant surprise in our era. There are only two catches… Audio-Technica A900

  • The braided wire is on the left side of the cans, while all the input sources are on my right so the cable gets in my way some times.. pretty trivial and personal.
  • The earpads that come with the package are unusually cheap pleather that become a distraction after a few hours use. This is the focal point of the article.

So, whats a person to do? I couldn’t return them (nothing severely flawed), nor felt like posting them on craigslist. Improvement is the only logical option! I scoured the net for various suggestions and modifications available and one that kept popping up was to -obviously- replace the original pads with better pleather, velour, or true leathers pads. Purchasing another set of pleather pads was not even an option, and velour pads apparently ruin the bass response and acoustics, so true leather it is.. specifically pads from the top-of-the-line ATH-W5000. The fit will supposedly be extremely tight because of the slightly smaller radius of the W5000 attachment ring, but it’s as good as it gets.

Audio-Technica W5000 flagship modelThe ATH-W5000 is the current Audio-Technica audiophile flagship model that has an ebony wooden casing, true leather earpads, fantastic frequency response, and a ludicrous MSRP value of $1700 (though reseller average is a -mere- $750). At this time, the replacement earpads can be purchased directly from Audio-Technica’s repair depot for $76.90, shipped to Canada… much less than online resellers. This brings my total purchase price to $276.90, which could have gone to another brand of headphones, but alas, live and learn :)

After the replacement pads arrived I popped off the originals and took my sweet time massaging and rotating the new pads into place. An important thing to at this point is that the original pads are not flat but actually angled to create a better seal around the ear, this makes the endeavour a bit of a challenge.

So here you have it, completed headphones, the moment of truth…

Blah. Well, it was somewhat expected while I was looking at the new pads. The core theory was correct, the material was better and should have allowed longer usage without annoyance, but they were overshadowed by new problems. It comes down to the design difference between the pads:

The problem comes with the shape of the opening in the pads as well as the amount of padding provided. My ears are on the large side but they fit comfortably into the oval shape inside the normal A900 pads, the W5000 pads are too small and irritate my ears by keeping them in an unusual position. The W5000 pads also contain less padding and as such create an imperfect seal that removes the amazing lows the A900 provides, this is proven by pressing the headphones against the ears, the bass returns. So, I’ll be selling/returning the W5000 pads, passively on the look out for something new, but it has become a reminder that sometimes, “good enough” is good enough :)

Unrelated to all this, this will probably be the first posting on the blog, so hi, hello, welcome. I don’t like empty introductions, but enjoy useful and informative content, hopefully you do as well, which is why you’re here. I would also like to say that there is no such thing as trivial information, just some that is too granular depending on the beholder, which is why I can’t stand the taste of some tomatoes or watermelon; how’s that for a segue? :p

    Have you considered the pads from the ATH-A1000(earpad item# HP-A1000)? They’re also made from the same “pleather” as the ATH-A500/700/900 but they are slightly more higher quality and smoother. My A500’s have virtually no pleather left and only spongy foam left and I’m really considering these pads from the A1000.

    Not a bad idea, if/when my current pads begin to degrade I’ll consider try the A1000 first and make a new posting, although that might take a while.

    I couldn’t wait as my A500 headphones had absolutely no pleather left and was basically all sponge, which is uncomfortable during long use. I purchased a pair of A1000 pads direct from Audio-Technica USA, I’ll see how these fare compared to the original micro-thin sponge pads. It’s almost a shame such a great line of headphones have crappy earpads.

    I forgot to say thanks for putting the picture comparing the two different earpads in your post!

    Forgot to mention, the A1000 pads came out to just under $40 with shipping included for anyone coming across this while googling.

    No problem SeO, I went through the trouble so others wouldn’t need to repeat the same mistakes, I’ll keep this trend in the future :)

    Do you still have the W5000 replacement ear pads? I would be interested for my W1000. If not can you provide the link where you got them?

    Nope, sold mine via the forum. I purchased them directly from the companies service department but you might find them on sale by someone on head-fi as well.

    Hi, can you please provide the link or more informations where did you buy those W5000 earpads? I understand that its from ATH service department, but I don’t know how to contact them, because only information I get is contact to my local depot, and I’m sure they will reap me off with 250% price.

    I got them directly from the Audio Technica Parts Department, check their site for contact information.
