Recommended Points!
Using a supercardioid gooseneck microphone with super high sound quality

It is a specialized gooseneck microphone with an arm that is designed to be attached to a violin, and the position of the microphone could be adjusted easily.
Frequency characteristics are reliable 2.4GHz band

According to the manufacturer's official website, the wireless range is up to 90 feet (about 27 meters)! Even if you move around a bit while playing, you can rest assured with this.
Comes with a special clip to hold the violin in place

It comes with a special clip that can be attached to violins and violas, so after connecting the microphone and clip, you can simply spread out the clip and clamp it to the instrument to easily secure the microphone in place.
You can freely move the microphone position

The U9 gooseneck microphone was designed to be placed on the bridge of a violin, and it could be adjusted in fine detail, so it could be fixed without any problems on a 4/4-size instrument.
Well-equipped with accessories

It comes with a carry case, microphone, transmitter, receiver, USB-C cable for charging, clip, windscreen, windshield, and manual, so you have everything you need.
I actually opened it and connected it to the speakers!
Let's take a look at the actual product! The contents are like this, and it's a fairly compact size that can fit in a bag.



First you need to charge it
First, you need to charge the receiver and transmitter. I used the USB type A and USB type C cables that came with the product to charge them at the same time. While charging, the red light was on, and when charging was complete, the red light went out. Charging time is about 30 minutes. When charging is complete, the light goes out automatically.

Connect the transmitter and microphone, and also connect the dedicated clip
The microphone was fixed simply by inserting it as shown in the photo and turning the screw. The clip was also easily fixed by inserting it from the bottom.


Fixing a microphone to a violin
The clip can be easily opened by hand, and once it is open, it can be attached to the violin and fixed in place. The inside of the clip has a non-slip rubber surface, and the spring is of a suitable strength, so there is no need to worry about damaging the instrument.


Adjust the microphone so that it is positioned above the top of the bridge
Adjust the position so that it comes directly above the bridge to pick up the sound well.

Connect the receiver to a device that can input from a microphone
This time, I connected a microphone using the JBL EON ONE Compact.
This is the speaker.
JBL / EON ONE Compact All-in-one PA system with built-in battery


Pairing
Turn on the transmitter and receiver and select a channel. In this case, I am only connecting one device, so I selected channel 1. When the connection is complete, the transmitter will light up blue and the receiver will light up green, as shown in the photo.


Let's play the sound!
When I actually tried playing a sound, it came out quite well! I think I was able to output the same clear sound as a violin from the speakers. I tried moving away from the device while it was connected, but it didn't disconnect and continued to work normally. I think this could be used on a stage, etc.

If you want to hear the actual sound, there is an introductory video on the official website, so please take a look! I think you'll be able to tell that the sound is being output really clearly.
