Sennheiser Momentum True Wireless 4 Review

Sennheiser Momentum TW4 Review

Voice & Call Noise Isolation 8.8/10

Each bud has multiple microphones for calls, with processing to reduce wind and background noise. Calls work over standard Bluetooth on phones and laptops.

Voice quality is clear in quiet places and acceptable in busier ones, though not a strength compared with business buds. Background noise is reduced, but voices can sound a bit processed in loud spaces.

For daily laptop meetings, a dedicated UC earbud such as the Jabra Evolve2 Buds remains the stronger call tool, with a boom-style mic array and a USB dongle that keeps audio wideband.

• Mics/Bud 3
• Mics 6
• Wind NR Yes (anti-wind mode)
• Call NR Beamforming

ANC & Transparency 9.5/10

Adaptive ANC adjusts to your surroundings, and a transparency mode lets sound in. There is also an anti-wind mode for outdoor use.

Cancellation is good on buses and in offices, cutting steady noise well. Against Bose and Sony flagships it lets more mid-frequency sound through, including voices and keyboard chatter.

For commuting it does the job, especially with a good tip seal. Frequent flyers who prize silence over sound quality should look at the Bose QC Ultra Earbuds.

• ANC Adaptive ANC
• Adaptive Yes

Battery & Case Charging 9.4/10

Sennheiser quotes up to 7.5 hours with ANC on and up to 30 hours in total with the case. A quick charge restores about an hour in minutes.

That is fine for a working day with mixed listening, though Sony and Poly last a little longer per charge. Lossless streaming draws slightly more power, so expect a little less when using aptX Lossless all day.

The case charges by USB-C or Qi wireless pad, and it is compact enough to fit in a jeans pocket. Its fabric-style finish resists scuffs better than glossy plastic cases.

• Battery 7.5 h
• With Case 30 h
• Wireless Chg Yes (Qi)
• Fast Charge Yes

Fit, Stability & Portability 8.2/10

The buds are compact with a smooth outer shell, and Sennheiser includes ear tips in four sizes. The water rating is IP54 for dust and splashes.

Most ears find them comfortable for a few hours. The shape sits fairly flush, so they work while lying back on a headrest, though some find the fit loosens with jaw movement.

Touch panels cover much of the outer surface, so adjusting the fit can accidentally pause music. Disabling some gestures in the app helps.

• Bud Weight 6.2 g
• IP Rating IP54
• Case Size 70.1 x 44.6 x 34.8 mm

Connectivity & UC Integration 7.1/10

Bluetooth 5.4 supports multipoint, Google Fast Pair and Auracast broadcast audio. Auracast lets you join shared audio streams in airports, gyms and venues that support it, without pairing to each transmitter.

The Smart Control app handles firmware, EQ and gesture settings, and LE Audio support should improve over time as more phones and laptops adopt the newer standard.

There is no USB dongle or Teams certification. These are personal music earbuds that also handle calls well enough on a phone. On a laptop they still work, but expect the narrower headset profile once the mic is active.

• Dongle No
• Multi-pt Yes
• BT 5.4

Sound & Audio Quality 8.9/10

Each bud uses Sennheiser’s 7 mm TrueResponse dynamic driver, and Snapdragon Sound supports aptX Lossless, aptX Adaptive, AAC, SBC and LC3. The Smart Control app adds EQ and a Sound Check personalisation tool.

The result is the most refined sound in this group. Instruments separate clearly, vocals sound natural and the bass is deep without blooming. Next to the Sony WF-1000XM5, the Sennheiser sounds more neutral and open.

With an iPhone you get AAC, which is still excellent but loses the lossless advantage that Snapdragon phones enjoy.

• Codecs SBC
• Driver 7 mm
• EQ Yes (Smart Control app)
• Freq. Range 5 Hz – 21 kHz
