/u/Liam_Nope - yes, you can make it work, but you need the right adapter - which depends on what kind of shotgun mic you have. Here are the correct adapters for each microphone type [Referral Links]:

Shotgun mic with 3.5mm output

• mics such as the Rode Videomic would require a [$15 TRS to TRRS adapter] (http://www.amazon.com/Rode-SC4-inches-Microphone-Cable/dp/B00L6C8PN0/ref=as_li_ss_tl?ie=UTF8&linkCode=ll1&tag=battleforthew-20).
  
  Shotgun mic with battery power and XLR output
  
  
• battery powered mics such as the Rode NTG-2 would require a [$34.95 Sescom XLR to TRRS adapter] (http://www.amazon.com/Sescom-iPhone-Right-Angle-Monitoring/dp/B005TE4KNK/ref=as_li_ss_tl?ie=UTF8&linkCode=ll1&tag=battleforthew-20)
  
  Shotgun mic with phantom power and XLR output
  
  
• phantom powered mics such as the Rode NTG-1 or Audio Technica AT875r would require a [$36.42 IK Multimedia iRig PRE preamp w phantom power] (http://www.amazon.com/IK-Multimedia-iPhone-Android-Devices/dp/B007534LFK/ref=as_li_ss_tl?ie=UTF8&linkCode=ll1&tag=battleforthew-20)
  
  Hope this is helpful and good luck!

Wired? We use a mic/headphone dongle... it works on our iPhones and a wide variety of the droid phones our on-air guys own.

The one below is not the exact ones we have, but is very similar. Ours have a longer lead on them... maybe 2.5' or so.

We have a Comrex Bric in the equipment room we can switch between 4 studios. We then use Luci Lite on the smartphones.... sounds like you are right in the studio. We often run the phone to a mixer so we can hook up an ambient noise mic for remotes so it sounds more like we are on location.
