Ranked in these QuestionsQuestion Ranking
Pro More fool proof
With a lack of buttons there's less chance that the person wearing it will accidentally disable or change settings on the device while recording/ streaming audio.
Pro High quality materials
Anodized aluminum for the body is pretty nice considering comparable offerings.
Pro Sleek design
Much more stealth considering how small and slim the unit is.
Pro Stealth/ discrete
This microphone can easily pass for a pen if you place the microphone like a pen in a shirt pocket with the clip showing on the outside of the pocket like this. This link shows an image of a different microphone, until I have the time to take a picture this will serve to get the idea across.
Con Battery is non-replaceable
Once the juice runs out, it's time to recharge and/or swap with second fully charged unit ready to go.
Con Hard to see when the unit is on or off
The blinking light is very seldom and dim. In a lighted room or outdoors during the day One can block out the light with hands to see if it's on or off. Or watch the Bluetooth connectivity on my phone disappear. A minor nitpick. The upside is that it's unlikely to cause an issue for filming purposes since the blinking part of the unit will be facing down inside a shirt pocket or on the collar of the shirt etc.
Con Doesn't work with Android phones
It does work with computers and iOS devices though.
Con Can't use external lapel micropones
You can only use the onboard microphone.
Con You can't use the microphone while it's recharging
Even if the microphone was capable of functioning while recharging, the jack that is used to charge the unit is the same jack where the microphone sits.
Con Non-standard charging port/cable
This unit uses the microphone jack to charge. This means if you lose the included charging cable, you might be stuck waiting and unable to record with the unit until your replacement unit arrived. Other units that use more standard and available Micro USB, to charge this is less of a problem.
Con Superseded by new model that is functionally different
The new model Ampridge Mighty Mic W+ can act as a wireless monitor. Not sure if it is possible to record and monitor at the same time. Based on the design of the Mighty Mic W, I would think not.
