RME Babyface Pro FS

At $499 the Babyface Pro FS stretches the "under $500" boundary, but RME's reputation for bulletproof drivers and pristine conversion justifies every penny. German engineering delivers the lowest latency of any USB interface on this list — sub-1ms round-trip on optimized systems, outperforming the #2 Steinberg UR22C by over 2ms. TotalMix FX is the most powerful routing and monitoring software in the interface world, offering 24-bit/192kHz conversion with a signal-to-noise ratio of 113 dB, which is 10 dB better than the average USB interface. Live performers, podcasters running complex setups, and producers who never want to troubleshoot driver issues buy RME once and never look back.
