Sennheiser MOMENTUM True Wireless 4 vs FiiO FH7S

Short answer: the Sennheiser MOMENTUM True Wireless 4. It ranks #48 of 68 in-ear headphones by sound quality, rated 3.3/5, at $249.95; the FiiO FH7S ranks #49, rated 3.2/5, and costs $299.99, so there is little reason to consider the other one.

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. The catch: 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 FiiO FH7S: Oratory1990 measured bass about 4.6 dB above the Harman target, so kick drums and bass lines hit with real weight for a hybrid built around a 13.6mm dynamic driver and four balanced armatures. The catch: Low mids run 2.4 dB hot on top of the bass lift, which can make male vocals and bass instruments thick.

Buy the Sennheiser MOMENTUM True Wireless 4. It is rated higher for sound quality than the FiiO FH7S and costs less, which makes it the one to get unless you need something the other one does better.

The Two Headphones In Full

Sennheiser MOMENTUM True Wireless 4: $249.95 Amazon eBay

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.

FiiO FH7S: $299.99 Amazon eBay

Pros: Oratory1990 measured bass about 4.6 dB above the Harman target, so kick drums and bass lines hit with real weight for a hybrid built around a 13.6mm dynamic driver and four balanced armatures. Treble is close to target, and an 18 ohm impedance makes it easy to drive from a phone despite the 104 dB/mW sensitivity. It suits warm, bassy tastes.

Cons: Low mids run 2.4 dB hot on top of the bass lift, which can make male vocals and bass instruments thick. A 6.1 dB peak near 8 kHz can make cymbals and sibilants sharp. The Tin HiFi P1 Max and FiiO FD5 both have higher ratings.
