Short answer: the iBasso IT01S, if you are buying new. The Sennheiser Momentum True Wireless 3 measures as well as it (#44 vs #46 of 68 in-ear headphones, 3.4/5 vs 3.4/5) but is discontinued, so only consider it used; the iBasso IT01S is still sold new at $89.95. The Sennheiser Momentum True Wireless 3’s replacement, the Sennheiser MOMENTUM True Wireless 4, is rated 3.3/5 at $249.95.
The case for the iBasso IT01S: A Harman score of 66 in Crinacle’s measurement shows the tuning lands reasonably close to what most listeners prefer. The catch: Deviation from the target averages 2.84 dB, so the response is not especially smooth.
Why pick the Sennheiser Momentum True Wireless 3: Active noise cancelling, Bluetooth 5.2 and aptX Adaptive support (alongside SBC, AAC and aptX) add real convenience, and battery life is 7 hours per charge with up to 28 hours using the case. The tradeoff: Presence between 3 and 6 kHz is 6.9 dB under target with a 7.6 dB dip near 4.4 kHz, so vocals, snare and guitar edges sound distant and veiled.
Buy the iBasso IT01S, since the Sennheiser Momentum True Wireless 3 is discontinued and only worth hunting down used.

The Two Headphones In Full
iBasso IT01S: $89.95 Amazon eBay
Pros: A Harman score of 66 in Crinacle’s measurement shows the tuning lands reasonably close to what most listeners prefer. The 16 ohm impedance and 109 dB/mW sensitivity mean a phone can drive it to loud levels. At 8 g per earbud with a 10mm dynamic driver, it is a light, simple wired set.
Cons: Deviation from the target averages 2.84 dB, so the response is not especially smooth. Without an inline microphone it cannot be used for calls, and the KZ PR1 has a higher rating.

Sennheiser Momentum True Wireless 3: $111.99 Discontinued Amazon eBay
Newer model: the Sennheiser MOMENTUM True Wireless 4, ranked lower, rated 3.3/5, released Feb 2024. It adds LC3. See every Sennheiser Momentum True Wireless generation.
Pros: Active noise cancelling, Bluetooth 5.2 and aptX Adaptive support (alongside SBC, AAC and aptX) add real convenience, and battery life is 7 hours per charge with up to 28 hours using the case. At 5.8 g per earbud with an IPX4 rating, it handles workouts and light rain. Oratory1990’s measurement shows bass and sub-bass within 1 dB of target, giving a clean, warm foundation that suits warm and bassy tastes.
Cons: Presence between 3 and 6 kHz is 6.9 dB under target with a 7.6 dB dip near 4.4 kHz, so vocals, snare and guitar edges sound distant and veiled. Air above 10 kHz runs 5.4 dB hot, with a peak of 4.9 dB near 10.5 kHz, which adds a hissy edge on top of the recessed mids. The preference score of 66 and deviation of 2.59 dB confirm the response sits well off the target. The KZ PR1 is rated higher at a similar cost, though it lacks wireless and ANC. Discontinued.
