It is important to know

When choosing the Samsung Galaxy Buds4 Pro R640 in white, it's worth checking more carefully whether the connection and functionality of the cable match your devices and desired usage. Although the appearance and basic functions are understandable to almost everyone, a wrong choice regarding compatibility or length can affect everyday use. Before buying, pay attention to some key practical aspects.

• Be sure that the cable connector fits perfectly with the device you want to connect, as an incorrect connection may limit use or completely disable the connection.
• Check if this cable supports data transfer in addition to charging - this is not a given with all cables and is a key feature for some users.
• Cable length has a significant impact on comfort; for office or home use, a longer cable is often practical, while shorter ones are more convenient on the go or when using with a power bank.
• If you have multiple devices or use cables in different locations, consider whether you need multiple cables or a cable with multiple connectors, but keep in mind that versatility sometimes means compromising on reliability.

In practice

🟢 Charging headphones or phone

The cable is very suitable for normal charging of Samsung or other devices, if the connector fits your headphones or phone.

🟡 Transferring data from device to computer

The cable may support data transfer if this functionality is confirmed for your model; we recommend checking before purchasing as not all cables support simultaneous charging and data transfer.

🟢 Extra cable for home or travel

As an additional or replacement cable, the product is very practical, especially if you frequently change locations or need a spare.

🟡 Use with multiple different devices

A cable can work with multiple devices if it fits all the ports, but universal use may mean it won't be ideal for every function.

🔴 Connecting older devices with non-standard connections

Due to its adaptation to modern connections, the cable is not optimal for older models that require, for example, Micro USB or Mini USB.

Answers to frequently asked questions

Does the cable allow for both charging and data transfer?

Enabled if specified for your model; we recommend checking the product specifications before purchasing.

What should I check before choosing a cable length?

Consider where and how you'll use it - a shorter cable is better for power banks or on-the-go use, while a longer one is better for stationary use by the bed or on a desk.

Is the cable compatible with all devices?

No, before choosing, check the connection type on both sides and compare it with your devices.

Can I use the cable as a spare for multiple locations?

Yes, an additional cable makes sense for use in multiple locations if it fits the connections of your devices.
