In the question“What are the best bluetooth microphones (excluding headsets) for mobile devices?” Nolan LiveMIC2 is ranked 3rd while Saramonic SR-WM4C is ranked 10th.

With this product, you are connecting the unit (the transceiver) directly to your tablet, phone, or other Bluetooth enabled device (the receiver). No receiver is supplied with this product. You must have something compatible for this to work with either the [A2DP](https://en.wikipedia.org/wiki/List_of_Bluetooth_profiles#Advanced_Audio_Distribution_Profile_.28A2DP.29) or [HSP](https://en.wikipedia.org/wiki/List_of_Bluetooth_profiles#Headset_Profile_.28HSP.29) Bluetooth profile. On iOS this does not work for Apple's built-in apps, but for some 3rd party apps, you can use your phone as the receiver. For Android it likely won't be as much of an issue. YMMV.

Cons
Con Flaky, low quality hardware
In less than a month, my unit became unreliable, sometimes it worked, sometimes it didn't.
Con The buttons are unclear about what they do
You have to look at the manual and memorize that pressing left or right on the directional pad will put the embedded microphone in either omnidirectional or cardioid pattern.
Con Requires a 3rd party app in order to use
Default video/voice recording apps of iPhone/Android don't support the use of a bluetooth microphone, you will need to use a different app for that.
Con Latency/Lag can be an issue
If latency lag is a concern, consider purchasing the Alead Nolan LiveMICRX2 instead as it has the same transmitter as this product and a Bluetooth receiver that claims 10x lower latency (meaning 10x faster transmission and receiving) than most Bluetooth devices. Using linked product would mean your mobile device would have to have a 3.5 mm microphone jack as that is how the receiever would connect to your mobile device.
You can also buy the Nolan receiver a la cart, although you lose the savings (~$2 at the time of this writing) by buying it in a bundle. It is also possible to purchase other stand-alone Bluetooth audio receivers or USB Bluetooth dongles (for computers) depending on your needs.
Con User reviews report echo effect
Con More distance beyond recommended range introduces more noise
Noise becomes an issue the further the transceiver gets from the receiver past the recommended range or with obstructions and radio interference.
Con Quality and durability issues
22% of customers rated it 1 star due to quality/durability issues.
Con Only 4 radio frequencies to choose from
This means if you are in a radio congested area, you may not get a clean signal. Other radio users and their audio sources may cut into your recording/live broadcasting etc. Only 4 channels might mean you can't operate.
