Shure SRH940.
Been listening for a few hours now.
Very bright to start with. These are minty, fully boxed with all accessories. Bought used from
eBay, I suspect they are near new and not run in. Possibly never used at all.
After an hour or so the treble settled down, requiring several dB less eq to make them listenable. I still prefer a bit of a roll off, and a tad of bass boost, but just a couple of dB at each end.
Quite a dry and clean character, loads of precise and focused detail. Much less easy going than the Shure 840 I have previously owned and liked. They don't have the tonal weight and richness of some of my planar magnetics, regardless of the eq applied. They are quite like the Sennheiser HD 599; very similar actually!
I'll put a headband cover on them to keep them minty and see how I get on with them over the longer term.
Let's see, how many headphones have I got now?...
Shure 940, Sennheiser 599, Oppo PM3, AQ Nighthawk, Monolith M1060 and M1060c, Hifiman Sundara, KLH Ultimate One, Audio Technica M50X & SR5BT, B&O H6, Beyerdynamic DT 990, Bose AE2, BQEYZ Autumn IEM.
I think that's all. Hmm, only 14. Must try harder.
