Along with the summary below, I have a review thread comparing the TMA-1 Studio with the Sony MDR-1R, Z1000, Sennheiser Momentum, Logitech UE 6000 and Audio Technica M50 here:

I also posted the following Youtube review of the TMA-1. If you like the video check out my channel for more reviews
Summary
BUILD
The TMA-1 look incredible. However there are a number of huge flaws. With the included foam earpads, the foam tends to peel away from the attachment disk (see the video). I was sent a replacement pair of pads by AIAIAI support (they were very good about it) which supposedly use a stronger glue, but after a while I encountered the same issues. I ended up using liquid nails glue to secure the foam earpads, which I prefer in sound and comfort. The TMA-1 has a very low clamping force which makes it very comfortable; however with the included coiled cable they end up pulling to the side because the coiled cable is heavy and the TMA-1 is not secure on the head. I ordered a straight cable and recommend it strongly over the stock coiled cable.
SOUND
The TMA-1 have a punchy dynamic sound, with rolled off highs but a slightly metallic treble that makes the entire headphone sound exciting, though extremely coloured. Despite the intimidating design however, sub-bass is actually quite poor and below 100hz notes get a little flabby and loose. They have a wide soundstage but don't sound particularly defined. They do however sound fun with some modern studio recordings. Despite the name I would never ever use this for studio monitoring.
OVERALL
The TMA-1 has some really critical design flaws despite being an absolutely gorgeous headphone. If they had a truly authoritative sound to match the design, these flaws could be forgiven. As it stands there are some real flaws that make this a bit of a non-recommendation for me.
