Sennheiser Momentum TW4 vs Soundcore Liberty 4 NC Comparison

Sennheiser Momentum TW4

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.

Soundcore Liberty 4 NC

Six microphones with AI processing handle calls. Voice pickup is clear in quiet rooms and acceptable in offices. In wind or on busy streets, background noise and voice artefacts become noticeable. For short calls it is fine, but daily meeting users should choose a business earbud. Laptop calls use standard Bluetooth headset audio, which narrows the sound compared with music playback.

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.

Soundcore Liberty 4 NC

Adaptive ANC 2.0 measures the ear canal and surroundings to adjust cancellation. Transparency mode is also included. For under 100 dollars, ANC is impressive, cutting engines, fans and traffic well. It cannot match the Bose QC Ultra Earbuds on voices, but the gap is smaller than the price suggests. Getting a good seal with the right tip size matters most.

Sennheiser Momentum TW4

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.

Soundcore Liberty 4 NC

Soundcore quotes up to 10 hours per charge, or 8 hours with ANC on, and up to 50 hours with the case. With LDAC, that falls to about 6 hours. That is excellent for the price and outlasts many premium earbuds. A full week of commuting is possible before charging the case.

Sennheiser Momentum TW4

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. 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.

Soundcore Liberty 4 NC

The stem-style buds are light and rated IPX4 for sweat and splashes. Soundcore includes five tip sizes. The stems make them easy to remove and adjust, though the shape is less distinctive than pricier rivals. The case is compact with a sliding lid, which is easy to open with one hand.

Sennheiser Momentum TW4

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.

Soundcore Liberty 4 NC

Bluetooth 5.3 supports multipoint, so the buds stay connected to a phone and a laptop at the same time. Multipoint is rare at this price and useful for hybrid workers who take calls on both devices. The Soundcore app handles EQ, ANC modes and firmware. Note that LDAC and multipoint cannot be used together on some firmware versions.

Sennheiser Momentum TW4

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 Sony WF-1000XM5 is its closest flagship rival. With an iPhone you get AAC, which is still excellent but loses the lossless advantage that Snapdragon phones enjoy.

Soundcore Liberty 4 NC

Each bud uses an 11 mm custom driver, and the buds support LDAC Hi-Res Wireless Audio on compatible Android phones, plus SBC and AAC. Default tuning is bass heavy, which some will enjoy on a commute. The app's EQ presets and HearID personalisation calm the low end and bring vocals forward. iPhone users get AAC rather than LDAC; Apple's AirPods Pro 3 are the iPhone-native alternative.
