Short answer: the Sennheiser MOMENTUM True Wireless 4. It ranks #368 of 450 in-ear headphones by sound quality, rated 3.3/5, at $249.95. The Muse HiFi Power ranks #378, rated 3.2/5, at $199, $50.95 cheaper, not enough of a saving to outweigh the sound-quality gap.
The case for the Sennheiser MOMENTUM True Wireless 4: This true wireless set adds active noise cancelling, Bluetooth 5.4 and a codec list that runs from SBC and AAC up to aptX Lossless and LC3. Watch for: Presence from 3 to 6 kHz is about 6.9 dB under target, with an 8.2 dB dip near 5.7 kHz, so voices and guitars sound recessed.
Why pick the Muse HiFi Power: A 14.5mm planar magnetic driver with about 2.3 dB of extra bass and sub-bass that stays within 6 dB of target down to 20 Hz, for a full, warm low end. The catch: Squig.link measurements show a 12.7 dB peak near 11.9 kHz on top of a 6.5 dB dip near 6.5 kHz, so the lower treble sounds dim while the very top can add a hissy sheen.
Buy the Sennheiser MOMENTUM True Wireless 4. It is rated higher for sound quality, and the $50.95 you would save on the Muse HiFi Power does not close the gap.

Older model: the Sennheiser Momentum True Wireless 3 (ranked higher, rated 3.4/5). See every Sennheiser Momentum True Wireless generation.
Pros: This true wireless set adds active noise cancelling, Bluetooth 5.4 and a codec list that runs from SBC and AAC up to aptX Lossless and LC3. Battery life is 7.5 hours per charge and 30 hours with the case, and IP54 resistance covers sweat and light rain. Oratory1990’s measurement shows bass about 0.6 dB above target, so low end is full without being overdone.
Cons: Presence from 3 to 6 kHz is about 6.9 dB under target, with an 8.2 dB dip near 5.7 kHz, so voices and guitars sound recessed. Air above 10 kHz runs 5 dB hot with a peak of 4.2 dB near 10.6 kHz, which can add a thin, sparkly edge. The Tin HiFi P1 Max has a higher rating, for a lower price.

Muse HiFi Power: $199.00 Audio46 eBay
Pros: A 14.5mm planar magnetic driver with about 2.3 dB of extra bass and sub-bass that stays within 6 dB of target down to 20 Hz, for a full, warm low end. The midrange from 200 Hz to 3 kHz stays within a decibel of target, so vocals sound natural. At 32 ohms and 106 dB/mW it runs fine from a phone. It matches the rating of the FiiO FH7S for less money.
Cons: Squig.link measurements show a 12.7 dB peak near 11.9 kHz on top of a 6.5 dB dip near 6.5 kHz, so the lower treble sounds dim while the very top can add a hissy sheen. The Shanling ME200 and FiiO FH3 both rate higher for less money.
