Need a school headset for both tablet devices and desktop computers? Get this popular single-plug school headset model bundled with an adapter to convert it's single plug to a dual plug that will work with desktop computers (or any other device) that have separate audio and microphone jacks. Many schools still have a mixed fleet of old and new devices, so we created this bundle so you can use the same headsets with multiple types of plug configurations. The additional length of the included 3ft adapter allows for the adapter to run down behind a desk to the back ports of a desktop computer. If you are using the front ports of a desktop and you do not need this extra length on the adapter, please consider our other bundle that includes a 6" adapter.
