ECM-B1M Shotgun Microphone with three directivity modes

I am using this mic with my Sony a6400 with analog output and onA7C with digital output. And sound quality with both is great. This microphone is small, light, easy to mount and the sound quality itself is excellent. The directional pattern option from full shotgun, to omni works very well. The freedom from batteries and cables and the digital sound which works on A7C is also great. Everything from sound quality, function and form factor is excellent and would make it a perfect travel microphone.
'bobble' mount which of course cannot be replaced by anything else, and which transmits every touch of the camera or wobble into a background of annoying interference that ruins it all. With tripod, this noose does not come but while hand-held, every touch to the camera create noise.

Overall: small form factor, no battery needed, quiet mount and stereo/mono feature. Ideal for Sony cameras specially ones that are capable of reading digital output.
