The microphone's build is surprisingly robust for its price. It's made of metal, which instantly conveys a sense of quality, feeling far more substantial than many plastic alternatives in this budget range.

Features and Functionality

The Fifine K688 boasts both USB and XLR connectivity, offering flexibility for various setups. Beginners can plug directly into their PC via USB, while those with more advanced audio interfaces can utilize the XLR option.

A standout feature is the tap-to-mute button, incredibly convenient for quickly silencing yourself during streams or calls. However, this function is limited to USB; XLR usage disables the tap-to-mute.

It also features a cardioid pickup pattern, effectively minimizing background noise – perfect for reducing distractions like keyboard clicks or fan noise.

Sound Quality Comparison: USB vs. XLR

Surprisingly, in my testing with a Stream Deck Plus and Wave XLR dock, the USB connection produced slightly better sound than the XLR connection. This might be due to several factors including inherent differences in the audio path, impedance matching, or driver issues with the specific setup used in this review.

The audio tests in the video show this mic’s performance over USB and XLR, both with and without filters applied. This allows viewers to make their own judgment on which sound signature they prefer.

Ultimately, the best method depends on your personal preferences, setup and audio interface.

Overall Conclusion and Recommendation

The Fifine K688 delivers exceptional value for its $51 price tag. Its solid metal build, dual connectivity options (USB & XLR), and surprisingly good audio quality make it a fantastic budget microphone.

While XLR performance might vary based on your setup, the USB connection consistently provided clear, crisp audio. For casual streamers, podcasters, or anyone needing a reliable microphone without breaking the bank, the K688 is a highly recommended option.

Ultimately, the decision between USB and XLR comes down to your specific needs and setup. For those seeking pure convenience and plug-and-play functionality, USB will likely suffice. Those wanting high-end flexibility or using advanced audio interfaces will appreciate the XLR option
