RGB搭載 FIFINE AmpliGame AM8 USB/XLR ダイナミックマイク

申し訳ありませんが、AM8マイクはFIFINE Genieソフトウェアと互換性がありません。FIFINE Genieソフトウェアに対応しているのは、AM8PROTマイク、SC8ミキサー、H13ヘッドセット、 BM38ブームアームスタンド、およびH19ヘッドセットのみです。

The AM8 microphone does not include an XLR cable, so you will need to purchase one separately. However, you can choose a bundle that includes an XLR cable, which offers better value than buying items individually.

For the XLR connection to work, you need a separate XLR cable to connect the mic to an audio interface (or mixer). You should control the functions (like volume, mute, or monitoring) on the audio interface (or mixer).

It works when using with a proper USB adapter. But we recommend using it only with PC and laptop, since the quality of the adapters may vary and the low-battery status of your phone may affect the performance of the mic.

iPhone/iPad with a type-C port needs a type-C male to type-A female adapter.
iPhone/iPad with a lightning port needs a lightning male to type-A female adapter.

⚠️If it's the lightning version, because of the protocol, it's highly recommend the adapter from Apple store. https://www.apple.com/shop/product/MD821AM/A/lightning-to-usb-camera-adapter
Android with a micro-USB port needs a micro-USB male to type-A female adapter.

The thread size is standard 5/8" and 3/8" of the AM8 yoke. So attach the mic onto a scissor arm stand, NO adapter is needed, just screw the mic in.

The main difference is about the tone, the AM8 sounds most like traditional dynamic microphones with a lot more of the bass, the K688 is more on the high-and-mid, and while Tank3 is the most neutral sounding one among the three.

That means the AM8 has the advantage of noise-rejection over the rest two if the environment is super noisy, like in your gaming room.
If you're concerned about the background but don't want your voice sound quite bassy, the K688 could be a better fit out of the three.
At last, the Tank3 fits a wider range of users, you don't have to worry about your voice getting muddier or more harsh.  

Besides the coloration, the appearance and the build quality might also be the deciding factors in this price range. If you want to stand out and add some flavor in the frame, the AM8 with a square shape and RGB lighting is the clear winner. If it's about the opposite style, then the Tank3 is the best fit for its super solid metal body, which is even 1/3 heavier than the K688 but in a more compact body.
