Fifine AmpliTank K688 review

The AmpliTank K688 brings the main idea of the PodMic USB and MV7+, a dynamic cardioid capsule with both USB and XLR outputs, down to a regular price of $72.99. Fifine says the cardioid pattern rejects sound from the sides and rear, such as a computer fan or hard drive, and lists a max SPL of 130dB for loud voices. In USB mode, you get a quick mute, a gain control and real-time headphone monitoring, and Fifine says no drivers are needed on Windows or Mac. Switch to XLR later and it works with a mixer or audio interface, which gives a beginner a path to grow. The 50Hz to 16KHz frequency response is narrower than the premium picks, and Fifine lists no onboard processing or companion app, so noise reduction and compression happen in your recording software. The base model includes a shock mount but no stand, though Fifine sells bundles with arms. We compared documented features and published prices; we did not test it.

Who it is for

New podcasters on a tight budget who want a dynamic mic that can move to XLR later.
