Unboxing and Initial Impressions
The Fifine AM8 arrived with a surprisingly sturdy stand, a welcome addition considering its budget-friendly price point. The base is weighted well, providing stability. The metal yoke mount is a standout feature, feeling robust and professional.
However, the plastic tightening knobs lack knurling, making them difficult to grip and secure. Even when tightened, the microphone felt somewhat loose, a noticeable drawback in build quality. The inclusion of both 3/8 and 5/8 inch thread adapters within the mount itself was a pleasant surprise.
Feature Comparison: AM8 vs K688
Both the Fifine AM8 and K688 are combo-jack microphones, offering both USB-C and XLR connectivity. This flexibility caters to various setups, from simple plug-and-play to more advanced interfaces.

The AM8 distinguishes itself with a capacitive touch mute button and RGB lighting (USB-C only), adding a modern touch. The K688, however, boasts a superior, plush windscreen – a significant comfort difference, though seemingly less impactful sonically.
Sound Quality and Performance
While Fifine claims both microphones share a similar sound signature, subtle differences exist. The K688 offers a slightly fuller, smoother sound, particularly in the lower frequencies. The AM8 presents a brighter, crisper high-end, potentially enhancing clarity but also potentially highlighting harshness.
Both microphones exhibit noticeable plosives, even with the windshields in place. The AM8 suffers more from handling noise and desk-related sounds, highlighting the impact of its less robust build. Positioning is crucial, especially for the AM8’s dynamic nature.
Conclusion and Verdict
The Fifine AM8 shines as a remarkably affordable USB microphone, great for casual use, gaming, and everyday communication. The included stand makes it a convenient out-of-the-box option. However, its susceptibility to handling noise and external sounds calls for improvements in build quality.
The Fifine K688 provides a noticeable step up in build quality and sound, exhibiting a fuller sound profile. While still susceptible to plosives and handling noise, it offers a more refined auditory experience and more resilient build. The choice ultimately depends on budget and priorities; the AM8 is a budget winner, but the K688 is better for professional use.
