Yes, you can replace both the included double headphones and the mic in the TSB bundles with a single headset microphone that fulfils both functions. But you must keep in mind that not every headset will be compatible with your system. As a rule of thumb, the headset will need to have two plugs (one for microphone and one for headphones), unlike most regular and PC headsets that feature only one plug. We recommend the Sennheiser model listed on this page.
