My a900x arrived today ... I could not resist when eBay had 15% off everything and we're only $160 delivered!
Thanks everyone for the review and description of these ... They're exactly as described. They are wonderfully musical ... They ARE like shure 940s with bass.
Just out of the box I knew I liked them already. It's probably not as tight and controlled as my shure 846 but soundstage is much more outstanding being big and wide and doesn't sound like a closed headphone. It's really nice and airy but vocals are full and solid and forward which I just love. Clarity is great too.
Haven't been into full size for a while but this makes the dt880 sound completely bland and boring and very flat.
The shure940 I had lacked bass but was one of my favourite headphones... The 900x is better IMO.
Not a comparison with the m50 either... The m50 doesn't have that airiness nor the wonderful mids... The m50 is so much more closed in and I didn't like the recessed mids.
Compared to the psb m4u, I thought the bass wasn't tight enough and was bloating into the mids and made everything abit muffled.
So even with just a few hours listening, these are the best full size I've had. It has that wonderful forward vocals I want from the 846 while having a big airy soundstage of my ie800.
Comfort wise ... They're quite good ... Nothing a little rubber band couldnt fix and is very comfortable for me.
Tried to tighten the spring inside but didn't have any success yet....will try again when I have time.
It's a keeper. I think I will buy another set for my best friend
I'm glad you found the joy of the a900x. If you are considering modding your a900x, it's a mix of two things.
1) Stretching the spring
2) You know how there's a 3 pin insertion for the white plastic piece? I messed up the insertion somehow by accidentally forcing the plastic piece in and now the wings actually rest on the earpads in its' relaxed form. Basically just rotating the winds 90 degrees inwards.
After this I no longer found the need to use an elastic band.
I preemptively sent Audio Technica an email that I might have messed up the wings, they offered to send me one for free but I never needed it.
