Same summary

Samsung Galaxy Buds4 Pro R640 black are designed for users who want the everyday freedom of wireless headphones with a good balance between sound, comfort and functionality. They are suitable for listening to music on the go, making calls, working or relaxing and particularly stand out for their integration with Samsung devices, where they enable quick switching and better connection. Due to the TWS design, they are a practical solution for use in combination with a smartphone, while satisfying those who rely on active noise cancellation in noisy environments or public transport. They may be less suitable for users who do not feel comfortable with in-ear headphones or are looking for the pronounced bass offered by larger over-ear headphones.

Answers to frequently asked questions

Are the Samsung Galaxy Buds4 Pro suitable for sports and exercise?

Yes, thanks to the compact TWS shape and low weight, they stay comfortably in place even during active movement, and they also provide a stable Bluetooth connection and basic moisture resistance.

How good is the active noise cancellation (ANC) in loud environments?

The ANC function is mainly effective for steady noise, such as sounds on public transport or in an open office, but for sudden high-pitched sounds, all TWS headphones have their limited operating ranges.

What devices are the headphones most compatible with?

They work best with Samsung devices, but can be used with all Bluetooth-enabled phones and computers, although the connection speed and some additional effects will be most pronounced in the Samsung ecosystem.

What should I do if I'm bothered by the sensation in my ear when wearing in-ear headphones?

It is recommended to try out the different sizes of silicone tips that are included, which can improve comfort. If you still find the feeling of pressure bothersome, classic (on-ear/over-ear) headphones may be better.
