Short answer: the Sennheiser Momentum True Wireless 2, though neither ranks well in its class. It ranks #1202 of 1291 in-ear headphones by sound quality, rated 1.6/5, at $243.36. The Sivga Nightingale ranks #1267, rated 1.0/5, at $229, $14.36 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, and the Truthear Nova, ranked #2 at $169.99, is a better place to start if sound quality matters.
The Sennheiser Momentum True Wireless 2 is the better-sounding pick. Active noise cancelling, Bluetooth 5.1 with SBC, AAC and aptX, and an IPX4 rating cover the features commuters and gym users want. The tradeoff: In oratory1990’s measurement the presence region from 3 to 6 kHz is about 9.6 dB below target, with a 10.7 dB dip near 4 kHz, so vocals and instrument attack sound pushed back and hazy.
What the Sivga Nightingale does well: Upper treble lifts about 3.3 dB for extra air and sparkle. Watch for: Presence sits about 12.6 dB low with a 13.1 dB dip near 3.5 kHz, so vocals and instruments lose some bite.
Buy the Sennheiser Momentum True Wireless 2. It is rated higher for sound quality, and the $14.36 saving on the Sivga Nightingale is not enough to make up the difference.
