Short answer: the Sennheiser Momentum 4 Wireless, though neither ranks well in its class. It ranks #424 of 481 over-ear headphones by sound quality, rated 2.5/5, at $213.04. The Sivga Audio Robin ranks #436, rated 2.3/5, at $149, $64.04 cheaper, a saving that is not big enough to make up the sound-quality gap. Both are rated below 3.0/5 among the 481 over-ear headphones; for better sound, the Sennheiser HD 550 ranks #8 at $199.95.
Why pick the Sennheiser Momentum 4 Wireless: Feature set is strong: active noise cancelling, Bluetooth 5.2 with SBC, AAC, aptX and aptX Adaptive, and a rated 60 hours of battery. The catch: That bass boost overshoots the Harman target by a clear margin and adds about 2 dB in the low mids, which can make vocals and bass guitar thick.
Why pick the Sivga Audio Robin: Bass is lifted about 9.1 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Watch for: An 11.2 dB peak near 11.9 kHz can make cymbals and sibilance sound sharp.
Buy the Sennheiser Momentum 4 Wireless. It is rated higher for sound quality, and saving $64.04 with the Sivga Audio Robin does not make up for the sound-quality gap.
