There's also a (surmountable) bandwidth issue with Bluetooth
With Bluetooth audio input, the bandwidth used is very narrow (typically 8 kHz). This translates into lower audio quality since they achieve such low bandwidth by cutting out parts of the audio, most noticeably the high frequencies.
If you can get a Bluetooth microphone that supports 16 kHz (sometimes badged as "wideband speech", "wideband audio"* or "HD voice") and has good quality components then the sound quality will effectively rival that of a wired connection. But 99.9% of of all Bluetooth microphones don't. And of course your phone has to support this too but most do.
Interference is basically a non-issue. Bluetooth is a lossless data transfer protocol. Though theoretically interference could reduce the effective bandwidth, that is not a problem in practice in this sort of application.

* Note that "wideband audio" is also sometimes used to describe the voice connection with the carrier, which is not relevant for this discussion.
