Head-Fier
I had not really considered any HFM stuff, but I'm only familiar with their open-back planars (Last two versions of HE-400i). I actually keep Dynamat around the house.Also consider the Hifiman HE-R9 with a decently in-depth review:

If you feel like the bass is too strong and would be willing to put dynamat in the ear cups to reduce vibration/distortion:

If you want to get a HE-R9 and make it wireless, then you should just also get a free Hifiman Deva Pro as well:

Lastly, to add more long-term comfort to any Hifiman headband:

I loathe the new HFM headbands, and I have a large-ish head, which may be a problem for me. I'll take a look. Thanks.
