I would love to use my Sennheiser PC350SE headset with my MacBook Air (13-inch, Mid 2013 model).
I recently purchased a Startech Headset Splitter hoping that this would allow me to use the headphones and microphone together. However the audio continues to play from the Mac, and only the Mac's internal microphone is being detected. I checked the Sound Preferences and found no entry for any external headset or external microphone.
Is it possible to use a headset with my MacBook Air? Microphone quality is important for me as I take part in a lot of online meetings and don't want the sound interference from other participants, system sounds or background music.
