Short answer: the HIFIMAN Ananda Nano. It ranks #6 of 481 over-ear headphones by sound quality, rated 4.5/5, at $319. The Sennheiser HD 600 ranks #11, rated 4.4/5, at $284.99, $34.01 cheaper, which does not close the gap in sound quality.
What the HIFIMAN Ananda Nano does well: A preference score of 94 puts it close to the Harman target, with bass from 60 to 200 Hz within 0.1 dB of target and the midrange within about 1 dB. The catch: The top end is the weak spot, with the air region above 10 kHz running about 4.6 dB hot and a 10.8 dB peak near 11.9 kHz, preceded by a 4.4 dB dip near 9.6 kHz.
Why pick the Sennheiser HD 600: It earns a preference score of 91, with the midrange from 200 Hz to 6 kHz within about 0.1 dB of target, giving vocals and acoustic instruments a very natural tone. The catch: Sub-bass is about 7.9 dB below target, so bass lacks rumble and weight on electronic and hip hop tracks.
Buy the HIFIMAN Ananda Nano. It is rated higher for sound quality, and the $34.01 saving on the Sennheiser HD 600 is not enough to make up the difference.

Frequency Response Compared
Both headphones’ measurements overlaid on the Harman target. Above the target sounds louder in that range, below it quieter. Each curve is the median of several independent measurements, shifted so its 500 Hz to 2 kHz average sits at 0 dB, so only the tuning is compared.
