Short answer: the Sennheiser HD 650. It ranks #65 of 429 over-ear headphones by sound quality (rated 4.1/5) at $326.70 and is still sold new; the Sennheiser HD 559 ranks #411 (rated 1.6/5) and is discontinued, so it is only an option used.
What the Sennheiser HD 559 does well: 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 650 is the better-sounding option. A preference score of 84 and a warm tilt of minus 0.27 give a relaxed, smooth sound, with bass from 60 to 200 Hz, mids and presence all within about 0.6 dB of target. The catch: Sub-bass is about 7 dB under target and the 6 to 10 kHz treble is nearly 5 dB low, with a 9 dB dip near 9.3 kHz, so cymbals and air sound dull and rumble is missing.
Buy the Sennheiser HD 650. It is rated higher for sound quality, and the Sennheiser HD 559 is discontinued, so it is only available used.

Pros: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. It uses 1 x 38mm dynamic.
Cons: Discontinued, so it is mainly found used. Presence sits about 3 dB low with a 14.7 dB dip near 9.7 kHz, so vocals and instruments lose some bite. Sub-bass is 5.7 dB short at 30 Hz, so deep bass lacks rumble. A Harman score of 27 places it in the lower part of the over-ear rankings.

Sennheiser HD 650: $326.70 Amazon $326.70 eBay
Pros: A preference score of 84 and a warm tilt of minus 0.27 give a relaxed, smooth sound, with bass from 60 to 200 Hz, mids and presence all within about 0.6 dB of target. The largest peak in the upper range is just 1.1 dB, so it avoids harshness on vocals and guitars. At 260 g it is fairly light, and it is a good match for listeners who like a warm tonality.
Cons: Sub-bass is about 7 dB under target and the 6 to 10 kHz treble is nearly 5 dB low, with a 9 dB dip near 9.3 kHz, so cymbals and air sound dull and rumble is missing. At 300 ohms it wants a dedicated headphone amp to reach its potential, and the open back leaks sound. See headphone amps and DACs with enough power to drive it.
