Headphone recommendation? (from Modartt too?)

I use Sennheiser HD 600 and have found them to be enormously satisfying.

That said, headphone choice is personal and other's experience won't necessarily serve as a guide for your own satisfaction.

- Open headphones tend to provide a "more natural" experience whereby the sound feels more ambient and less "injected" into your head. Open headphones allow you to hear ambient sound, and do not insulate the sound they produce from the environment.

- Quite a few headphone manufacturers boost different frequency ranges (low, mid, or high) to create a "fun" sound profile or one more suited to drum-based musics. This contrasts with a "flat" response favored in monitoring. Knowing your own sonic-profile preference can guide you toward a satisfying result. The HD 600 I mention aspires towards flatness, and some would say a more muted higher end.

Commonly preferred headphones:

Sennheiser HD 650, HD 598
Audio Technica ATH-M50x
BeyerDynamics DT 880 and DT 770

plenty more ...

Headphone choice makes an enormous difference.

Best of luck

Thank you both for the replies. After a bit more research I ended up ordering the Beyerdynamic DT 990 Pro 250 ohm along with a modest desktop headphone DAC/amp. I'm not very experienced with audio equipment but I'll let you know what I think after I try them out, they should be arriving tomorrow.

I have a pair of Audio Technica ATH-M50 (birthday gift!). They are good, but a little on the bright side, very clinical and accurate.
I also have a pair of Grado S-80 open air, that sound very good. Not as detailed as the M50, but a warmer sound.

I enjoy my beyerdynamic DT880 headphones.  They are over-the-ear, but of open design, so that you hear what is being played through the earphones, but still hear the world around you.

Sennheiser HD 598 good enough too

I own these 4 headphones:

Beyerdynamic DT770 (32 ohms)
- favorite for listening, playing. my main headphones in the studio

Sony MDR-7506
- favorite for critical listening, DJ’ing and shooting videos ... least favorite for listening/playing

AKG K240 Studio
- my favorite as far as the most "real" sounding for acoustic instruments, the bass response is nice and clear (not heavy or pushed). The K240 Studios are also my favorites as my most comfy pair headphones, I can literally and physically forget I'm wearing them. But .. I feel like they need a proper headphone amp to sound their best, they can be a too quiet/remote with typical consumer amps (like I said they're not bass heavy). In contrast, the other 3 headphones can be easily driven by almost any headphone jack, especially the 32 ohm DT770 and SR850. For this reason, I don’t reach for the K240 Studios as much as the others in this list and they end up being my studio “guest” headphones but still one of my favorites. They sound great when the amp matches and you get a nice strong signal, with the open back, classical, jazz, latin and vocals sound very good/real on these headphones.

Samson SR850 (32 ohms)
- favorite knock-around, bang-up headphones (out-of-studio, rehearsal, gigs), and are a good bang for the buck. Wait for sales or shop around you'll find them for around US$30. Performance is 90%+ of what the other more expensive headphones give you. They work best with a bit of EQ to tame the highs. I treat them like a pair of old jeans, you’re not going to wear them to a formal party, but for daily casual use, they’re good.
