How far can I move away from my smartphone while still staying within Bluetooth range?
Most smartphones support a Bluetooth range of up to 10 metres or 30* feet.
To understand Bluetooth range, it is important to consider the two main Bluetooth power classes
for audio devices, including Jabra devices and smartphones:
Class 1 – up to 100 m/300* ft
Class 2 – up to 10 m/30* ft
*Range information is a general guideline. The Bluetooth class must be the same for two paired
devices, otherwise the wireless range will be limited to the potential range of the least powerful
device. For example, a Class 1 device paired with a Class 2 device would normally result in
Class 2 wireless range.
Due to the effect on battery consumption, the vast majority of smartphones use Bluetooth Class
2. This means that you can expect Class 2 wireless range, even if the connected Jabra Bluetooth
audio device is advertised as supporting Class 1.
In addition, the potential range is further reduced by obstacles and electromagnetic interference
(EMI). When indoors, other electronic devices, walls, and furniture may also reduce the signal.
Outdoor use, without obstacles and EMI, usually results in greater wireless range. However,
leaving your smartphone inside your vehicle and walking away from it (for example, leaving a
truck cab and walking behind the trailer) could result in a loss of audio. If you take your
smartphone with you, the Bluetooth audio device you are using will always remain within range.

What are Bluetooth classes, versions, and profiles?
Class
The class of a Bluetooth device determines the wireless range of the device. It is possible to
connect two Bluetooth devices with different classes without issue. However, they will default to
the lowest class and its range capabilities.
There are several other factors, such as interference and positioning of the Bluetooth device, that
can also impact the overall operating distance of Bluetooth devices.
Version
Just like other technologies, as the Bluetooth technology is improved, new versions become
available. All Bluetooth versions are backward compatible and will default to the available
features of that Bluetooth connection. Connected Bluetooth devices are not required to have the
same Bluetooth version for compatibility.
Profile
Bluetooth profiles determine the kind of data that is exchanged using Bluetooth technology. For
