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.
Con Must use a 3.5 mm jack to connect receiver to your mobile device
Con Generates handling noise
The transceiver unit creates a lot of handling noise if using the internal microphone. To avoid this it is recommended to use a lavalier microphone plugged into the 3.5 mm input jack.
Con Battery life is only 2 hours
This unit uses one AAA battery and users report that the units only last 2 hours in real world use.
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 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 Can't use external lapel micropones
You can only use the onboard microphone.
Con Doesn't work with Android phones
It does work with computers and iOS devices though.
