It is important to know

Before purchasing the Samsung Galaxy Buds4 Pro R640, it's worth considering how their specific design and features adapt to your usage pattern. The key to satisfaction is primarily in the balance between advanced functionality (e.g. noise cancellation) and everyday comfort and adaptability. The important differences come from a combination of fit options, daily mobility, and technical development of the generation.

• The in-ear design with silicone tips offers good passive noise cancellation and stability during movement, but is not necessarily the most comfortable for all users when worn for hours.
• Models with active noise cancellation (ANC) show the most advantages in noisy environments – but this can increase battery consumption and reduce autonomy if you use the feature frequently.
• This generation of wireless headphones is convenient for quickly switching between devices and mobile use, but advanced features (e.g. sound personalization or expanded in-app options) are usually better integrated with devices from the same manufacturer.
• If you want headphones primarily for sports or public transportation, pay attention to the combination of fit, sweat protection, and battery life - one choice isn't always the best for all activities.
• With years of use, advanced software support, new Bluetooth technology, and ongoing application upgrades can significantly impact the long-term user experience, especially if you follow the development of the ecosystem.

In practice

🟢 Daily listening and calls

Buds4 Pro allow for comfortable, discreet use for music, podcasts, and phone calls, and work wirelessly with most devices via Bluetooth.

🟢 Work in an open office or on the go

The combination of ANC and a snug fit works well to reduce distracting noise in the office or on public transport, especially when work requires concentration.

🟡 Sports and exercise

Silicone eartips typically provide stability during movement, but comfort or fit is not always ideal for all ear types – a preliminary test is recommended for regular sports use.

🟢 Traveling by plane or train

The headphones' effective noise cancellation and compactness mean they are particularly suitable for reducing ambient noise on the go.

🟡 Gaming or watching movies

Headphones may be suitable for occasional gaming and movies, but some advanced wireless technologies to reduce latency are not always utilized to the maximum, so there may be a noticeable delay in audio on some devices.

Answers to frequently asked questions

Do Samsung Galaxy Buds4 Pro work with Android and iOS devices?

Yes, the headphones use Bluetooth and are compatible with most modern phones and tablets running Android or iOS.

What does active noise cancellation (ANC) mean on these headphones?

This feature uses microphones to detect external noise and help reduce it, which is especially useful in noisy environments (e.g. an office or public transportation).

Are the Buds4 Pro suitable for sports?

In practice, they are stable and suitable for light sports or exercise, but fit and comfort may vary depending on the shape of an individual's ear.

Is it possible to use the headphones for several hours at a time?

The headphones allow for hours of continuous listening, but some users may experience discomfort due to the silicone eartips over time.

Do all headset features work on all phones?

Basic functions (playback, calls, ANC) are generally available, more advanced options (e.g. application settings) may be limited to devices from certain manufacturers.
