StarTech 4 Pin to 2x 3 Pin 3.5mm Splitter Have you recently purchased a newer laptop or Ultrabook and now you cant figure out where to plug in your favourite headset? Most new laptops and Ultrabooks come equipped with a single 3.5mm 4-position (4pin) audio port that supports both audio input and output. A great number of headsets on the market come equipped with two separate headphone and microphone connectors that are not compatible with this new configuration. The MUYHSMFF headset adapter features two 3.5mm 3-position ports that provide a separate headphone and microphone connection that can be connected to the single audio port on your laptop. Alternatively, you can also connect a separate microphone and powered speakers if you prefer to use Skype or chat online without using a headset.Please note this item is non-returnable, see our returns policy for more information.
