The ニンテンドーUSBワイヤレスマイク is a solid choice for Nintendo Switch users who enjoy JOYSOUND Karaoke. It provides a convenient wireless solution for karaoke enthusiasts, and I've had some enjoyable singing sessions with it.
However, I must point out that the microphone's sound quality can be a bit disappointing, especially when the sound is output through a high-grade speaker system. The audio quality feels like low-quality radio or 64 kbps bitrate audio, which prevents me from giving it a five-star rating.
In terms of build quality, it falls somewhere in the middle, neither cheap nor super high quality. It gets the job done but doesn't feel particularly premium.
One downside is the lack of PC support, even though it connects via USB. It's exclusively designed for the Nintendo Switch, so keep that in mind.
If you plan to use two of these mics simultaneously, you might encounter some challenges, particularly if your dock's design isn't accommodating. Additionally, the fact that each mic is tied to the included USB dongle, using similar wireless radio spectrums, can present future connectivity risks.
Overall, I recommend this mic if you're looking for a straightforward Nintendo Switch karaoke setup and don't require advanced technical knowledge to set it up. It's a handy addition to your JOYSOUND Karaoke experience, even though it has its limitations.
