I’m not wanting anything right now and am taking a pause for at least a year of upgrading/adding to my collection. At this point I’m thinking gains are gonna be pretty minimal, and it will mostly be if I want a drastically different tuning:
Sennheiser HD-650: Nothing has beaten this for my preferred sound signature. I even had Clears for 2 years, and after selling 650s, and then reacquiring them, I just found even with the improved transience and subbass, they just have a weird mid-range that doesn’t handle things like guitar distraction/effects well that makes most rock lose it’s edge. Maybe someday I’ll find a fabled HD-650 killer, but until then, these will probably me my daily’s. The mid-range presentation is so smooth and cohesive, and even if the sub-bass can be lack, for most music that isn’t EDM it’s more than enough extension to get most of it. I could listen to these for hours without having any fatigue.
Audeze El-8 Closed: Scratches the transient response itch I was using the Clears for with some great (if ever so slightly recessed) linear bass response across the whole spectrum. The mid-range of these is THICK and is almost an inverse of how the 650s present (EL-8s seem focused more on upper mid range, while the 650s focus on lower mids). Great treble response that feels really in control, and the detail retrieval on these things is insane.
Sennheiser Momentum 3: Insane bass cans. Truly the best and most skull rumbling bass I’ve heard on a mobile can. Somehow has an insane, emphasized bass that doesn’t bleed into the middrange. Mids are classic sennheiser house sound, and the treble is really laid back. (I’m learning I really don’t like a pushed treble) The sound stage for these is shockingly wide. If you’re coming from the Momentum 2, demo these as they are quite a drastic change from previous revisions.
Sennheiser Urbanites: first pair I owned when I started wondering what “real” headphones were. Friend sent me his when he was done with them. Incredibly tight clamping force, ear pads get hot, and there’s virtually no sound stage, but the FR is pleasant, bass extension is a typical consumer tuning and it doesn’t really offend in what it sets out to do. Definitely keep them around for a fashion statement more than for sound, but it’s something I’ll still reach for them on occasion. They’ll always have a special place for kicking me into this hobby.
