I like the build and materials.
To me they give off the vibe of "dentistry" equipment, If you appreciate utilitarian materials of good quality serving their purpose also taking the neat construction into account, they are sexy. And dont come off as cheap but rather special IMHO.
Tried them briefly before and returned them because I was not a fan of the sound but got them recently on sale. I am all about comfort and you can't find lighter headphones. And for the aforementioned reason, that the materials and design impressed me, and made me happy.
If a Sony guy were to be reading this, the one thing that looks a bit plasticky is the "Y-hinges", but that was when I looked at them through negative glasses now. And I think I am picky. But I dont think heavy things, metal or completely matte surfaces (but it'd been nice here, on the silver ones) is synonymous with high quality.
I like the sound a lot more this time around, and the best source being a Hifime sabre 9018 dongle to my pc, but sounds great on my phone and the onboard soundcard as well. At first using the PC front jack it didn't connect properly and actually produced passable sound, and had to reconnect it around halfway to get proper connection. I listen to a lot of different music, a lot of IDM and generally a lot of electronic of a variety of genres, rock, funk, metal, ambient, classical music, OSTs. They work well in games as well.
1AM2s cup material which I found very comfortable in the short time I tried them before is still very good but not as amazing as I remembered. Still heaps beyond most synthetic materials. You can also tell just by looking at it.
I feel like a lot of care and attention to detail has gone into the construction and design and choice of materials.
Would love to try the 1As, both for the sound (since I like bloated bass) and how they compare in comfort.
I have The Coolermaster headset which are OEM Tekstars (the 1A "copy") and I dont think the cups were as comfortable (possibly the material, synthetics are often itchy for me but 1AM2s material is not). And they weigh about as much as the 1A I think (38 gram diff to 1AM2) and it was also a factor.
Need to try those more.
Maybe the 1As were better comfortwise.
