Our take
The FIFINE K688 is the surprise budget contender — dual USB and XLR, around $73-$80, with a metal body and onboard headphone jack. Looks like a Shure SM7B at a quarter of the price. Brand reputation isn't where Shure or Rode sits, but the build punches above the price.

In depth
The FIFINE K688 (also marketed as AmpliTank K688) is the surprise budget contender in the dual-USB/XLR space, sitting in the $73-$80 range at Best Buy, FIFINE Direct, and Newegg. The visual design deliberately echoes the Shure SM7B with side-address handling and a large mesh grille, and the build quality genuinely punches above the price — metal body, solid heft, broadcast-grade aesthetic.
Specs: dual USB and XLR outputs, onboard headphone jack with monitoring volume control, mute touch button on the body, gain knob. USB output is 16-bit, which is the same as the Q2U and a step below the ATR2100x's 24-bit.
The stand mount is plastic rather than metal but the mic itself feels solid. Where it shines is the price-to-build-quality ratio. For $73-$80, you get a metal-bodied broadcast-style mic with all the modern conveniences (USB, XLR, headphone monitoring, mute, gain) that would cost three times more from Shure or Rode.
The look alone is a meaningful upgrade for podcasters who care about video presentation. Where it falls short is brand reputation — FIFINE sits in tier-2 brand territory versus Shure, Rode, or Sennheiser, and resale value is meaningfully lower.
The 16-bit USB output also lags the ATR2100x's 24-bit. Still one of the most interesting mics in the sub-$100 category in 2026.
