Short answer: the Sennheiser Momentum True Wireless, though neither ranks well in its class. It ranks #1211 of 1291 in-ear headphones by sound quality, rated 1.5/5, at $180. The Softears Studio 2 ranks #1233, rated 1.2/5, at $152, $28 cheaper, not enough of a saving to outweigh the sound-quality gap. Both are rated below 3.0/5 among the 1291 in-ear headphones, so if sound quality matters, consider the Truthear Nova instead, ranked #2 at $169.99.
The Sennheiser Momentum True Wireless is the better-sounding option. Bass is lifted about 2.5 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. The catch: Presence sits about 10.9 dB low with a 12.4 dB dip near 4.0 kHz, so vocals and instruments lose some bite.
Why pick the Softears Studio 2: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. Watch for: Presence sits about 12.6 dB low with a 15.6 dB dip near 5.3 kHz, so vocals and instruments lose some bite.
Buy the Sennheiser Momentum True Wireless. It is rated higher for sound quality, and the $28 saving on the Softears Studio 2 is not enough to make up the difference.
