Wireless Microphone – Samson Go Mic Mobile Lavalier Wireless System with PXD2 Beltpack & LM8 Microphone for Smartphones – Black

A good wireless microphone for smartphones (and appears to be useable with cameras and other items). Reviews are good and for £15 (with shipping included) it seems to be a really good way to pick up a wireless mic that is good and cheap.
Other mics around the price are infact bluetooth mics are horrible. See the reviews below and the audio is decent.
