FiFine M9 Overview
Similar to other wireless microphone sets we have looked at recently, the real meat and potatoes of the M9 kit can be found within the black charging case. Not overly large, the charging case comes in at 103.5mm x 61mm x 43.8mm – small enough to fit in your pocket, but not where I would want to carry it around at. The front of the case features a textured pattern to give it a bit of flair, and a set of four white LEDs at the bottom let you know the battery status of the case itself.
On the back of the case we have that same textured pattern, as well as a USB-C port for charging the internal battery. That internal battery has a capacity of 1200mAh, which is plenty to recharge both of the 150mAh transmitters, as well as the 280mAh receiver, multiple times over. FiFine lists the charging time to be about 2.5 hours, but that will somewhat depend on the power source you are providing to the case.
Opening the charging case reveals the two transmitters flanking the center-placed receiver. The top of the case has foam padding for each internal component to make sure they stay in place and don’t rattle around. In addition to that padding however is a magnetic pairing between each component and the charging case, which sort of pulls each component into its spot and helps keep them in place.
Taking a look at each component individually, first up is the receiver. The receiver is the centerpiece of the system, bridging the gap between the wireless transmitters and your device of choice. A mostly square box at 41.3mm x 42.9mm x 15mm, the face of the receiver has that same textured pattern and a FiFine label.
The backside features a spring-loaded clip for attaching the receiver to various objects, though it is better suited for sliding in to a hot or cold shoe on a camera or recording rig, as it is sized just right for that.
The top edge of the receiver is home to the visual feedback of the device, and you will find indicators for power, mono vs stereo operation, transmitter link status, and A and B channel volume levels.
The bottom edge of the receiver gives access to a USB-C port for charging the unit outside of the charging case, as well as two contacts for making the connection with the pogo pins in the charging case.
On the Left side of the receiver is a small power button and two buttons labeled “A” and “B”. The A and B buttons are used to adjust the volume of each channel.
The Right side of the receiver is home to the Mono/Stereo mode button to alternate between those modes, a pairing button, and the 3.5mm audio out port.
As far as the specifications you can’t see, the M9’s receiver has an internal 290mAh lithium-ion battery that is good for up to 12 hours of use, with a charging time of just 1.5 hours. The M9 utilizes a 2.4GHz wireless signal for transmission, and has a bit of a confusing range. While the box states up to 100ft, the specifications found on the user guide and website list 50M, which is about 150ft. In my testing I found that this range was pretty accurate, and all depends on your environment, line of site, and what sort of mediums the wireless signal has to travel through.
Moving over to the pair of transmitters, we have a look similar to the receiver, but smaller – 42.9mm x 28.5mm x 15mm. The front of the transmitter has the same textured pattern, as well as the FiFine smiling logo. Towards the top right corner are two LED indicators – the left is for power, and the right is for status. The power indicator is red when low, green when charging, and off when working or fully charged. The status indicator flashes blue when unpaired, is solid blue when paired, and red when paired and muted.
Around back is the same clip that we have on the transmitter.
The top side of the transmitter is home to the omnidirectional condenser used to pick up nearby sounds. Surrounding the microphone is a cutout that allows you to attach the included windscreens with a simple twist. You can also see the aforementioned LED indicators here as well.
The bottom of the transmitter has a similar setup to the receiver – USB-C and two contacts for charging.
The left side of the transmitter is home to the power button, which also pull duty as the mute button.
The right side has a button for pairing and another for noise cancellation. There is also a small LED indicator for showing the noise cancellation status.
Regarding the specifications of the transmitters, each has as frequency range of 20Hz to 20kHz, with a 16-bit depth and 48kHz sample rate. The internal 150mAh batter is good for up to six hours of use.
