The Shure EAADPT-KIT features three useful adapters compatible with all standard headphones and earphones. Included is a 1/8" - 1/4" adapter as well as an international airline adapter that connects your 1/8" headphone jack to the dual-pronged connectors found on airplanes. Theres also a volume control that you can insert between your headphones and the output of an audio device. This is is great for high-output sources where even the lowest volume setting is still far too loud.
