The Sennheiser KA 600i (article 505799) is a coiled connection cable that lets the Sennheiser MKE 600 shotgun microphone record directly into an Apple iPhone or iPad. It runs from an XLR-3 female connector, which plugs onto the microphone's XLR output, to a four-pole right-angled 3.5 mm mini-jack plug wired specifically for the combined headset socket of iPhone and iPad, so the microphone is recognised as an external mic input rather than headphones. Sennheiser gives the full length as approximately 40 cm, and the coiled section keeps it short and tidy when the microphone is mounted on a phone rig or small camera. The MKE 600 can run from its own AA battery when phantom power is not available, which is what makes this direct connection practical. Typical users are mobile journalists, vloggers and content creators capturing interviews and ambient sound. Note that newer iPhones and iPads without a headphone jack also need Apple's own adapter. Weight is 60 g.
