Sennheiser MOMENTUM True Wireless 4 (Black Copper)

The Sennheiser MOMENTUM True Wireless 4 in Black Copper is Sennheiser’s flagship true wireless earbud, centred on a 7 mm TrueResponse dynamic driver and a Bluetooth platform built to stay current. It supports aptX Lossless and aptX Adaptive alongside SBC and AAC, carries Bluetooth 5.4 with LE Audio, and uses hybrid adaptive noise cancelling with three beamforming microphones per earbud for calls. Battery life reaches up to 7.5 hours per charge and 30 hours with the case, which charges over USB-C or Qi wireless. The Black Copper finish pairs a dark body with copper-toned accents.

Sound first, with lossless wireless

Sennheiser’s TrueResponse driver is tuned for the signature MOMENTUM presentation: full low end, clear midrange and detailed treble across a 5 Hz to 21 kHz range, with sensitivity of 107 dB and total harmonic distortion below 0.08 percent. Codec support is where this generation moves ahead. With a compatible phone, aptX Lossless carries CD-quality audio over Bluetooth without the usual compression, aptX Adaptive balances quality and latency for video and games, and LC3 over LE Audio prepares the earbuds for the next wave of transmitters and Auracast broadcasts. The Smart Control app adds Sound Personalization, which builds a profile from your listening preferences, a five-band equaliser, Sound Check presets and Sound Zones that switch settings by location.

Adaptive noise cancelling and calls

The hybrid ANC system adapts continuously to changing surroundings, keeping aircraft, train and street noise down without pumping artefacts, and an anti-wind mode helps outdoors. Transparency can be engaged when awareness matters. Three MEMS microphones per earbud use beamforming to focus on your voice and reduce background noise on calls, covering a 100 Hz to 10 kHz range. Touch controls on each bud are customisable in the app, so volume, playback, ANC and voice assistant sit where your fingers expect them.

Fit, battery and charging

Four sizes of silicone ear tips and three sizes of ear fins are included to secure the fit, important both for comfort and for the passive isolation the ANC builds on. Each bud weighs 6.2 g. Playtime is up to 7.5 hours with ANC off and 7 hours with it on, with the 820 mAh case extending total use to 30 hours; a quick charge of 8 minutes gives about an hour of playback. The case itself, at 66.4 g, charges by USB-C cable or any Qi wireless pad. The earbuds are IP54 rated against dust and splashes, covering workouts and wet commutes.

Built to stay current

Bluetooth 5.4, LE Audio and Auracast readiness mean these earbuds are designed for the audio sharing and broadcast features now rolling out in airports, gyms and newer phones, rather than being stranded on an older standard. Multipoint keeps two devices connected for laptop work and phone calls through the day.

Choose the MOMENTUM True Wireless 4 if sound quality is the priority and you want flagship codecs, strong adaptive cancellation and a platform that will not feel dated quickly. Black Copper is the finish for listeners who want the flagship without the standard black or silver look.
