Short answer: the Sennheiser HD 599. It ranks #188 of 417 over-ear headphones by sound quality (rated 3.6/5) at $189.95 and is still sold new; the Sennheiser HD 515 ranks #318 (rated 2.9/5) and is discontinued, so it is only an option used.
Why pick the Sennheiser HD 515: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. Watch for: Discontinued, so it is mainly found used.
The Sennheiser HD 599 is the better-sounding option. A preference score of 73 and a modest 2.74 dB deviation from the Harman target in oratory1990’s measurement make this a fairly smooth open back. The tradeoff: Sub-bass falls about 6 dB under target below 60 Hz, so the extra warmth sits higher up and the deepest rumble is missing.
Buy the Sennheiser HD 599. It is rated higher for sound quality and still sold new, while the Sennheiser HD 515 is discontinued.

Pros: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural.
Cons: Discontinued, so it is mainly found used. An 8.7 dB peak near 3.2 kHz can make cymbals and sibilance sound sharp. Sub-bass is 10.7 dB short at 30 Hz, so deep bass lacks rumble. A Harman score of 58 places it in the lower part of the over-ear rankings.

Sennheiser HD 599: $189.95 Amazon $189.95 eBay
Same family: the Sennheiser HD 569 (lower-end model, ranked lower, rated 1.6/5).
Pros: A preference score of 73 and a modest 2.74 dB deviation from the Harman target in oratory1990’s measurement make this a fairly smooth open back. Bass runs about 2 dB above target and the lows through the low mids are about 2.7 dB up, which gives vocals and guitars a full, warm body. At 50 ohms and 106 dB sensitivity it is easy to drive, and at 250 g it is light.
Cons: Sub-bass falls about 6 dB under target below 60 Hz, so the extra warmth sits higher up and the deepest rumble is missing. A 9.6 dB dip near 9.8 kHz and about 3.5 dB less air above 10 kHz take the sparkle off cymbals, while a 3.7 dB peak near 5.7 kHz can add some edge to vocals. The open back leaks sound and offers no isolation.
