Do the Buds 4 Pro need a Samsung phone for Hi-Res Audio?

Yes. The 24-bit/96 kHz Hi-Res Audio runs over the Samsung Seamless Codec, so it needs a compatible Galaxy device. Other phones fall back to standard Bluetooth codecs.

How is the noise cancelling?

Adaptive ANC adjusts to your surroundings and is aimed at commuting and office noise. It is competitive but not the deepest cancelling on the market.

Are they good for calls?

Six microphones with AI-powered noise reduction are built for voice pickup. Owners report clear calls in everyday conditions.

Can I wear them in rain or during workouts?

Yes. IP57 water and dust resistance covers sweat, rain and dusty environments.

What is 360 Audio with head tracking?

It places sound around you and follows head movement for a theater-like effect. It works best with supported Galaxy devices and content.

What comes in the box?

The earbuds, a charging case and silicone ear tips. Check the listing for the included tip sizes.

Our take on the Samsung Galaxy Buds 4 Pro SM-R640 True Wireless Bluetooth Earbuds

The Galaxy Buds 4 Pro are Samsung's premium true wireless earbuds, built around a two-way speaker system with dual amplifiers, 24-bit/96 kHz Hi-Res Audio over the Samsung Seamless Codec, and adaptive ANC that adjusts to your surroundings. They add 360 Audio with head tracking, six microphones with AI noise reduction for calls, and IP57 water and dust resistance. The canal-fit silicone tips and metal finish suit Galaxy phone owners who want tight ecosystem integration and strong noise cancelling. Against rivals like the AirPods Pro and Sony WF-1000XM series, they lean on the Seamless Codec and Galaxy features rather than best-in-class ANC depth.
