Bluetooth products and variants explained

Bluetooth is a wireless technology used in three of our product series: the Presence series, the MB Pro series, and the MB 660 series.

You can find more information for these product series on our website:

Bluetooth products can be paired directly with other Bluetooth enabled devices without the need of a base station. If you’re using a Bluetooth headset with a PC however, we recommend using our dongle – the BTD 800 – rather than the internal Bluetooth of your computer.

Bluetooth devices can send wireless signals using very little power, meaning that it is well suited to applications such as headsets and other portable electronics. This also means that the range of our Bluetooth products is lower than our DECT products, and may vary depending on the end-device you are connecting to.




Bluetooth standards and Bluetooth profiles

Bluetooth technology is available in a number of different standards, such 2.0, 2.1, and 3.0. These represent advancements in the chips used, but have little influence on the compatibility of our headsets with other Bluetooth enabled devices.

If you want to make sure that our headsets will work correctly with your Bluetooth device, then please check the Bluetooth profiles which are present. You can check these in the documentation supplied with your smartphone, or by contacting the manufacturer.

To ensure that our headsets work correctly with your Bluetooth enabled device, please ensure that the following profiles are present:

HFP: hands free profile

HSP: headset profile

A2DP: advanced audio distribution profile

AVRCP: audio/visual remote control profile



Pairing and security

Bluetooth devices must be paired with one another to establish a connection. This must be done once, allowing the devices to authenticate their connection, and then the devices will be saved so that they can be connected effortlessly in the future.

This pairing process ensures that your connection is secure, and cannot be intercepted by third parties. During the pairing process, the two devices generate what is called an E0 stream cipher, which is used to encrypt the data packages being sent between them.



Density with Bluetooth products

Bluetooth products have limits on the density of devices which can be used in one area. You will reach this limit at around 10 to 12 devices, and exceeding this limit may result in a deterioration in call quality, in particular for your conversation partner on the other end of the line.

Please bear in mind that this limit concerns all Bluetooth devices in a given area, even if these are not headsets. This could, for example, be a wireless mouse or keyboard, or your smartphone if you have Bluetooth active.

If you are going to be using more than the recommended number of Bluetooth headsets, but still wish to use a wireless solution, it may be worthwhile considering of one of our DECT headsets instead.



Bluetooth headsets in comparison

We have three series of Bluetooth products, ensuring that we will have a product which will be suitable for your needs.

The Presence is a small, in-ear headset which is designed to be our most mobile solution. The small size ensures portability, and smart technologies built in to the units three microphones ensure that unwanted background even outdoors in windy conditions.

The MB Pro series are overhead headsets available in both one and two sided options. Its flexible microphone boom arm and ultra noise cancelling technology mean this unit will deliver the ultimate speech clarity while still ensuring freedom of movement.

The MB 660 represent the best our headsets have to offer. The large, ear-encompassing earpads combined with our Active Noise Cancellation technology ensure that you can work undisturbed even in noisy open-office environments. This is the only headset within our business headset portfolio which not only offers noise cancellation on the microphone, but also on the speaker for the user.



Bluetooth headset variants

All of our Bluetooth products are available in different variants, which can be recognised by the abbreviations at the end of the product’s name.

Products with no abbreviations, such as MB Pro 2 or Presence, represent the basic package of the headset, without any special accessories. 

Products with the abbreviation UC at the end of the name come with an included dongle for using your headset on your PC. UC stands for ‘unified communications’.

Products with the abbreviation UC ML or UC MS are also delivered with a dongle, but this dongle also carries certification for use with Microsoft’s Skype for Business.

Please note that it is not possible to purchase the MB 660 headset on its own, as this product is only available in UC and UC MS variants.
