Self-contained bluetooth mic at DVinfo.net

Howdy folks,

It's awfully quiet in here. I hope everyone's had a good summer. Here's another random topic for contemplation.

Does anyone make a small Bluetooth mic that can pair with generic BT devices ... i.e. NOT need its own special receiver or proprietary smartphone app? But perhaps could connect generically with a phone. Hopefully about the size of a Rode Go II. Just curious what people are making these days.

Peace, out. ;-)

Wouldn't latency be a big problem with with using a bluetooth microphone for video? I mean, if you were shooting the video on a phone with a bluetooth mic, then I suppose it could compensate. But seems like using it as a wireless mic with a regular video camera would be a problem.

The Shure MoveMic is the best sounding bluetooth solution directly into your phone. The system is expensive but they offera mobile only package for $249 https://www.bhphotovideo.com/c/product/1803901-REG/shure_mv_one_z7_movemic_one_direct_to.html/BI/2855/KBID/3801. While other systems like DJI offer bluetooth the quality isn't good but a much better value.

Boyd,
Latency is a good question. I've been trying to research this (starting essentially from scratch). From what I've found, latency can very widely depending on which codec is used. I have not seen any indication that it can be shorter than ~40 mSec. I believe that, for any given codec, it will be a fixed amount for the duration of any given recording, so once it's synced in post it should be stable.

Pete,
Thanks for the info about the Shure system, and for the other links! I'm reading this very late at night, but I will certainly explore all that info tomorrow.

This makes me think back to some older systems such as the Wii Audiolink system (mfg. Jancus). I'm pretty sure those also used 2.4 Ghz. Apparently they still have some current products. I wonder whether they were some proprietary digital system not relying on the BT standards.
