How we ranked these audio interfaces
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.
- Inputs weight 3
- Mic preamps weight 2
- Outputs weight 1

Buying advice: 4 channel USB audio interface
Count the inputs you record at once
The BOMGE U404, the Kmise, and the CIXUN have 4 inputs. The MOTU M6 has 6 inputs. Count the microphones and instruments you record at the same time, then match that count to the pick. A higher count suits sessions with more sources, while a lower count suits a single voice and one instrument.
Check phantom power and sample rate
The BOMGE U404, the BOMGE BMG22, the Kmise, and the CIXUN carry 48V phantom power for condenser microphones. The BOMGE U404, the Kmise, and the CIXUN record at 24-bit/192 kHz, while the BOMGE BMG22 records at 32-bit/192 kHz. Compare those two figures side by side before you choose.
Look at monitoring in the set
The BOMGE U404 gives zero-latency monitoring through a headphone output with independent volume control. The BOMGE BMG22 and the MOTU M6 give loopback for streaming. The CIXUN gives two headphone jacks with their own volume controls and an FX reverb control. Compare those monitoring facts before you choose.
