Have you recently purchased a newer laptop or Ultrabook and now you can't figure out where to plug in your favorite 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 MUYHSMFFADW white 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. Headset Connectivity Simply connect the headphone plug from your headset into the audio output port marked with the headphone symbol, and connect the microphone plug into the audio input port marked with the microphone symbol. Plug the adapter into the audio port on your laptop and you're all set.

Just plug in your microphone into the audio input port marked with the microphone symbol, and plug your powered speakers into the audio output port marked with the headphone symbol, and connect the adapter to the audio port on your laptop.

Tuck the adapter in with your tablet or slip it inside another carrying case. It works great with tablets and smartphones that have a single audio port.

This high quality 3.5mm headset adapter is backed by StarTech.com's lifetime warranty. Please note: This adapter is not a headphone splitter or Y-cable. It cannot be used to split the audio output to two separate sets of headphones or speakers. Some laptops and mobile devices will not work with all external microphones. This is typically caused by an impedance mismatch between the microphone and the device. This is due to hardware incompatibility and is not a limitation of the MUYHSMFFADWadapter.
