Samsung Galaxy Buds3 Pro / Sennheiser MOMENTUM 4 Wireless

SSC UHQ only works with the Galaxy S24, S23, Z Fold6, Z Flip6, Z Fold5, Z Flip5 and Tab S9 series on One UI 6.1.1 or later; other phones use AAC or SBC.

aptX Adaptive works only with Android phones that support it; iPhones use AAC. Multipoint connections are managed in the app.

PBP and TMAP are broadcast and telephony/media profiles that come with LE Audio.

Separate drivers for treble and bass let each focus on its own frequency range.

Siren Detect turns on ambient sound when a siren is heard nearby. Adaptive ANC and some AI features need a Samsung phone.

The VPU picks up bone vibration while you talk to help separate your voice from background noise.

360 Audio uses head tracking to keep sound fixed in space; it needs One UI 3.1 or later.

Talk time is 4.5 / 20 hours with ANC on and 5 / 22 hours with it off. The case supports wireless charging.

Earbuds should be dried before going back into the case when wet or sweaty.

With no certification against sweat or rain, care is needed when it gets wet during exercise.

The ear pads fully surround the ear; Sennheiser cites a lightweight design, padded headband and deep cushioned earpads for long-wear comfort.

The frequency range describes measurement limits; the sound you hear is also shaped by the in-app equaliser and sound personalisation.

Hybrid ANC uses both outer and inner microphones; adaptive mode changes the level of cancellation to match ambient noise.

Sennheiser says the 60 hours was measured with an iPhone at medium volume; higher volume and aptX Adaptive can shorten it.

When listening over USB-C, the headphones decode digital audio internally; the analogue cable works even with a flat battery.

Smart Pause stops playback when the headphones are taken off and resumes when they are put back on; Auto On/Off shuts them down to save power when not in use.
