Most IEM bodypacks and music players have 1/8" outputs, but if you're connecting to a Mixing Console, DJ Mixer or a HIFI Headphone Amplifier, 1/4" is the way to go. This gold-plated 1/8" to 1/4" stereo adapter bridges the gap between your earphones and the rest of the world. Our convenient 3-Pack makes sure you're never short on adapters.
