Nothing Ear (a) vs Sennheiser Momentum TW4 Comparison

Nothing Ear (a)

Each bud carries three microphones, and Nothing's Clear Voice processing is trained to separate speech from background noise such as traffic and chatter. Voice quality is clear indoors and acceptable outside. Wind can still cause some interference, which is common at this price. For laptop calls, the buds act as standard Bluetooth headsets.

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.

Nothing Ear (a)

Nothing rates the ANC at up to 45 dB, with adaptive and transparency modes. Smart ANC adjusts strength to your environment. Cancellation is excellent for the price, quieting trains and office hum effectively. It cannot match flagships with voices, but it beats most budget rivals. A good tip seal improves results noticeably, and the app's ear tip fit test helps you choose the right size.

Sennheiser Momentum TW4

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.

Nothing Ear (a)

Nothing quotes up to 9.5 hours per charge and 42.5 hours with the case with ANC off, or 5.5 and 24.5 hours with ANC on. With ANC on, a full workday needs a recharge in the case. Without ANC, battery life is excellent. The case charges over USB-C, and there is no wireless charging.

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.

Each bud weighs 4.8 g, and they are rated IP54 for dust and splashes. The stem design is light and secure. Most people find them comfortable for long sessions. The transparent stems look distinctive and fit easily in most ears. The case weighs 39.6 g and is wide, which makes it less pocketable than some rivals.

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. 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.

Nothing Ear (a)

Bluetooth 5.3 supports multipoint, Google Fast Pair and Microsoft Swift Pair. The Nothing X app works on Android and iOS. Multipoint keeps the buds connected to a phone and laptop, which suits hybrid workers. On Nothing phones, ChatGPT voice integration is available. The app handles EQ, gesture mapping, ANC modes and firmware, with a low-lag mode for games and video.

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.

Nothing Ear (a)

Each bud uses an 11 mm dynamic driver with a PMI and TPU diaphragm. Codecs include SBC, AAC and LDAC for higher-resolution streaming on compatible Android phones. The sound is balanced with lively bass and clear vocals. LDAC adds a touch more detail, while the Nothing X app's EQ lets you adjust tuning for podcasts or music.

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 result is the most refined sound in this group. Instruments separate clearly, vocals sound natural and the bass is deep without blooming.
