Sennheiser MOMENTUM True Wireless 4 vs Etymotic ER4XR

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 Etymotic ER4XR ranks #54, rated 3.0/5, and costs $299, so there is little reason to consider the other one.

What the Sennheiser MOMENTUM True Wireless 4 does well: 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.

The case for the Etymotic ER4XR: Upper mids sit within 0.5 dB of the Harman target and low mids within 0.4 dB, so vocals and instruments come through clearly and naturally. The tradeoff: Sub-bass is about 7.2 dB under target and bass is 2.6 dB low, so kick drums and bass lines lack weight and rumble.

Buy the Sennheiser MOMENTUM True Wireless 4. It is rated higher for sound quality than the Etymotic ER4XR 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.

Etymotic ER4XR: $299.00 Amazon eBay

Pros: Upper mids sit within 0.5 dB of the Harman target and low mids within 0.4 dB, so vocals and instruments come through clearly and naturally. Oratory1990’s measurement gives a preference score of 62, and the single balanced armature driver suits listeners who want a neutral, analytical presentation without added bass.

Cons: Sub-bass is about 7.2 dB under target and bass is 2.6 dB low, so kick drums and bass lines lack weight and rumble. Treble from 6 to 10 kHz is 5.4 dB low, with an 8.6 dB dip near 6.7 kHz, which dulls cymbals. A 45 ohm impedance makes it a bit harder to drive than most phone-friendly earphones, and the FiiO FH7S has a higher rating.
