Short answer: the Sennheiser HD 400 S. Both are rated 3.4/5 for sound quality (#275 and #272 of 481 over-ear headphones), and the Sennheiser HD 400 S costs $69.95 against $89.99 for the Moondrop Joker, so with nothing between them on sound quality, price settles it.
The case for the Moondrop Joker: A broadly balanced tuning with a preference score of 69 against the Harman target. Watch for: About 5 dB less bass than the Harman target below 150 Hz, which can sound thin on pop, hip hop and electronic music.
What the Sennheiser HD 400 S does well: Crinacle’s measurement gives it a solid preference score of 68, a respectable result for a budget closed headphone. Watch for: A 3.2 dB spread around the target means the response is not especially smooth.
Buy the Sennheiser HD 400 S. Both are rated the same for sound quality, and it costs $20.04 less than the Moondrop Joker.
