Short answer: the Thinksound ov21. It ranks #93 of 216 over-ear headphones by sound quality, rated 3.8/5, at $97. The Tanchjim Rita ranks #110, rated 3.7/5, at $89.99, $7.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
What the Thinksound ov21 does well: Sub-bass under 60 Hz sits about 4 dB above the Harman target and the 60 to 200 Hz bass about 2 dB above, so kick drums and bass lines have real weight and rumble. The catch: A dip of about 6 dB near 7 kHz followed by a 5 dB peak near 12 kHz leaves cymbals and sibilance uneven, dull in one place and glassy in another.
Buy the Thinksound ov21. It is rated higher for sound quality, and saving $7.01 with the Tanchjim Rita does not make up for the sound-quality gap.

The Two Headphones In Full
Thinksound ov21: $97.00 Amazon eBay
Pros: Sub-bass under 60 Hz sits about 4 dB above the Harman target and the 60 to 200 Hz bass about 2 dB above, so kick drums and bass lines have real weight and rumble. At 50 ohms and 99 dB/mW it runs loudly from a phone or laptop without an amp. The closed back isolates from room noise, and an inline microphone allows calls.
Cons: A dip of about 6 dB near 7 kHz followed by a 5 dB peak near 12 kHz leaves cymbals and sibilance uneven, dull in one place and glassy in another. Low mids are about 2.5 dB under target, which thins male vocals and guitar body. At 453 g it is the heaviest of its closest rivals, and the Audio-Technica ATH-M40x holds a higher rating at a similar price.
