Immersa comes with a four-pole connector that will allow you to use with laptops, phones, tablets and other devices. When the time comes to connect it to a desktop computer, an adapter will allow you to separate the audio into two three-pole connectors for audio input and output. Add to this its retractile microphone that appears or disappears according to your needs, and you have a headset that will provide exactly what you need when you need it.
