Guide: Questions you should ask yourself before buying a Bluetooth hands-free car kit

What is a Bluetooth hands-free car kit?

A Bluetooth hands-free car kit is a combination of a speaker and microphone that is permanently installed in a device or vehicle. The special feature of this is that neither a loudspeaker nor a microphone has to be brought to the ear or mouth. This means that your hands remain free and you can, for example, keep your hands on the wheel while driving a car and talking on the phone. In some cases, you can even control a Bluetooth hands-free car kit with your own voice. This gives you the convenience of wirelessly controlling your smartphone without touching it. Being able to talk on the phone while driving is practical and sometimes important. However, the mobile phone on the ear is far too dangerous and also not allowed. For this reason, Bluetooth hands-free kits are now an integral part of many people's everyday lives.

How does a Bluetooth hands-free car kit work?

A Bluetooth hands-free car kit works with the help of Bluetooth, which must be activated in the respective end device (e.g.: mobile phone). For example, you pair your mobile phone with the hands-free car kit. This process varies from product to product.

Bluetooth is a radio standard. It is built into a wide variety of electronic devices, making it possible to transmit data over short distances. A Bluetooth device can therefore replace cable connections between different end devices.

Buying criteria: You can use these factors to compare and evaluate Bluetooth hands-free car kits

In the following, we will show you which aspects you can use to decide between the many possible Bluetooth hands-free car kits. The criteria you can use to compare Bluetooth hands-free car kits with each other include:

Number of devices

It is great for you to know that there are Bluetooth handsfree kits that can be paired with multiple devices. For example, if a couple or several family members share a car with the same hands-free kit installed, there is no need to pair a new device with the Bluetooth hands-free kit each time, saving you time and effort.

Connection / Mounting method

Bluetooth hands-free car kits can be mounted in different ways, for example in the car. Typical ways to mount this device in the car include the dashboard, the interior by a specialist car technology company and the sun visor. The installation in the interior and serves to make the device an integral part of the dashboard and thus directly connected to the car's system. To give you a better idea of the whole process, we have prepared a video for you with instructions on how to install a Bluetooth hands-free car kit: https://www.youtube.com/watch?v=S5eYBS8_dW8&frags=pl%2Cwn You can install the Bluetooth hands-free car kit on the dashboard and sun visor on your own and with little effort, for example, with a clamp or an adhesive side to the device.

Voice control

With the help of the voice control, you can operate the device without any further clicks after mounting and pairing your end device.

If a Bluetooth hands-free car kit has voice control built in, this criterion provides additional comfort. Operation includes, for example, answering calls, setting a route or playing music on your end device. With some hands-free car kits, all these gadgets can be implemented with your voice alone.

Voice quality

The voice quality of a built-in Bluetooth hands-free car kit depends on the quality of the car's audio system. In contrast, the voice quality of external hands-free devices (e.g. dashboard, sun visor) depends on the electronic device itself.

Battery life

Battery life varies from device to device. Some handsfree devices do not need to be charged externally and therefore have an unlimited battery life. Other handsfree devices, on the other hand, need to be charged externally after a few hours using a USB cable, for example. However, there are Bluetooth handsfree devices that can be connected to a device on the cigarette lighter in the car with the help of a USB cable. This charges the device during use and you no longer need to charge the device externally.

Size

The size of the Bluetooth hands-free car kit is essential for you, as it must not hang in your field of vision when driving, for example. Such a device should not obstruct your view and should not hinder you in any way. However, the manufacturers of Bluetooth hands-free car kits take this factor into account in great detail and are concerned about your safety while driving.
