Sennheiser Momentum True Wireless 4, White Silver

The Sennheiser Momentum True Wireless 4 is an in-ear Bluetooth headphone with TrueResponse drivers, adaptive noise cancelling and Auracast, bringing lossless sound to your ears — here in White Silver. It combines audiophile ambition with the freedom of true wireless earbuds.

Why the Momentum True Wireless 4?

At its core, the TrueResponse system works with 7 mm drivers, already proven convincing in the larger models. Bluetooth 5.4 with LE Audio and Auracast makes it future-proof, and with aptX Lossless you listen without loss, provided your source plays along. Adaptive ANC, transparency mode and a total of six microphones round out the package — including IP54 protection against dust and splashing water.

What you hear

A powerful, clean sound with fine treble detail and rich but controlled bass. Through the Smart Control app you tailor your own sound profile via a guided test, 5-band EQ and Sound Zones — from neutral listening to a bass kick on the train.

Who is the Momentum True Wireless 4 for?

For anyone who wants audiophile sound without cables on the go, on the train or during sport — thanks to IP54, a bit of rain or sweat is no problem either. Straight talk: this is an in-ear for on the go, not an open headphone for sofa concerts. And for aptX Lossless you need a compatible source; without one it still plays superbly over AAC or aptX.

Our verdict

One of the most versatile true wireless earbuds in its class: audiophile sound, strong ANC and future-proof technology in a small housing. We at HD Zürisee in Wädenswil are happy to help you weigh it against the right over-ear.

Frequently asked questions

How long does the Momentum True Wireless 4's battery last?

Up to 7.5 hours per charge of the earbuds and up to 30 hours total with the charging case. An eight-minute quick charge gives you around one hour of playback — the case charges either via USB-C or wirelessly via Qi.

What do Auracast and LE Audio bring?

Both make the earbuds future-proof. LE Audio brings the efficient LC3 codec, Auracast allows the same audio stream to be sent to multiple receivers — for example to share music with someone or listen in on public Auracast sources.

Is the Momentum True Wireless 4 water resistant?

The earbuds are dust- and splash-water-protected per IP54. So sweat during sport or a rain shower are no problem. But it's not made for swimming or showering — IP54 covers splashing water, not submersion.
