The Sennheiser MOMENTUM True Wireless 4 (MTW4) is Sennheiser's flagship true wireless earbud, built for audiophile-level listening in a compact, daily-use form. Built on the Qualcomm S5 Sound Gen 2 platform with Snapdragon Sound, it supports Bluetooth 5.4 with aptX Lossless, aptX Adaptive, LE Audio, LC3, and Auracast, making it one of the most comprehensively connected true wireless earbuds available.

Sound is delivered through Sennheiser's 7mm TrueResponse dynamic driver, capable of up to 24-bit/96kHz audio resolution. Lossless audio support ensures bit-for-bit transmission from compatible Android sources, while the Sennheiser Smart Control app enables deep personalization through guided sound profiles developed with Germany's Fraunhofer IDMT, a 5-band EQ, Sound Zones, and Sound Check. Sound Zones automatically apply preferred audio settings when you enter or leave a defined location.

Adaptive ANC uses a 6-microphone system (3 per earbud) to automatically adjust noise cancellation to the surrounding environment. Transparency Mode restores ambient awareness at a tap without removing the earbuds. The same microphone system supports AI-enhanced call quality via the Qualcomm chip, isolating your voice from background noise.

Battery life is 7.5 hours per charge (ANC off) with 30 hours total including the charging case. Quick charge delivers 1 hour of playback from 8 minutes of charging. The case supports both USB-C and Qi wireless charging. Battery Protection Mode in the Smart Control app optimizes charging cycles to extend long-term battery lifespan. The earbuds are IP54 rated for splash and dust resistance.

Each pair ships with multiple sizes of silicone ear tips and ear fins, with a fit test built into the Smart Control app to confirm seal and optimize ANC and bass response. Available in Black Graphite, Black Copper, and White Silver.

All in-stock orders placed before 5pm EST Monday through Friday ship the same day. Free ground shipping on all orders over $9.99 within the 48 contiguous United States.

Frequently Asked Questions

Does the Sennheiser Momentum True Wireless 4 support lossless audio?

Yes. The MTW4 supports aptX Lossless via Bluetooth 5.4, enabling bit-for-bit transmission of CD-quality audio from compatible Android devices. On iOS, audio is delivered via AAC. For the highest quality listening experience, a compatible Android device with aptX Lossless support is recommended.

What is the difference between Momentum True Wireless 3 and 4?

The MTW4 upgrades to Bluetooth 5.4 with aptX Lossless and aptX Adaptive support, adds LE Audio and Auracast compatibility, improves the ANC system with a 6-microphone design and AI-enhanced call quality, introduces Qi wireless charging, and adds Battery Protection Mode for extended lifespan. The TrueResponse driver is the same 7mm design but with a retuned acoustic system.

What is Auracast and does the Momentum True Wireless 4 support it?

Auracast is a Bluetooth standard that allows a single audio source to broadcast to unlimited compatible receivers simultaneously, including hearing aids, earbuds, and speakers. The MTW4 supports Auracast via a firmware update. This is relevant for public venue broadcasts at airports, stadiums, and cinemas as the standard becomes more widely adopted.

How does Battery Protection Mode work?

Battery Protection Mode is an optional setting in the Sennheiser Smart Control app that optimizes charging cycles to reduce long-term battery degradation. It limits the maximum charge level to preserve cell health over hundreds of charge cycles. The trade-off is a slight reduction in maximum runtime per charge. It can be enabled or disabled at any time.
