Apogee and Sennheiser have teamed up to produce high-quality lapel mics with lightning connectors, meaning they plug right into "modern" iPhones, iPads, and iPod Touch devices. The two companies announced this partnership earlier in 2015 and will be bringing the ClipMic to market in May of 2015 (watch this space for when you can get one for yourself!).
By the term "modern iOS devices," Sennheiser gives the following list of devices you'll be able to use the clipMic on:
One reason the new ClipMic will be great (besides its on-board mic preamp and converter) is that you'll be able to use BOTH the headphone jack AND the attached microphone on the iOS device. Most of the current crop of microphone attachments for iOS devices plug into the headphone jack, making it difficult or impossible to monitor the audio as it's being recorded.
I mentioned the high quality hardware. You can read more about that, and about more details in this article about the project - http://www.audiomediainternational.com/new-gear/sennheiser-and-apogee-collaborate-on-clip-on-mics/04359
