This section helps you understand if your headset can be used with Vocera badges.
If the headset being connected to a Vocera badge has a 2.5mm TRS connector, with the impedances of the earpieces and microphones within the common impedance range, and has been manufactured by a reputable vendor, the headset should work reliably with a Vocera badge. Headsets from Plantronics and Jabra containing the 2.5mm TRS connector have been proven to work well with Vocera badges.
There are many 2.5mm to 3.5mm headset adaptors, which in principle would permit a smartphone headset to work with a Vocera badge. But there is a complication.
Modern smartphones use TRRS connectors to provide the stereo audio and the microphone, however two different pin configurations have emerged for the TRRS connector.
The early equipment manufacturers such as Nokia, Samsung and Sony Ericsson, implemented a pin configuration known as OMTP. Later equipment manufacturers such as Apple, HTC and Android phones implement a different pin configuration known as CTIA. This means that mixing headsets between different brands of equipment may not work unless you are sure of the pin configuration being used by that brand of equipment.
The pin configurations of the 3.5mm TRRS headsets are not directly compatible with a TRS interface so a simple 3.5mm to 2.5mm adaptor is unlikely to work unless it has been specifically designed for this purpose.
