: The MVSILICON B1 USB Audio Driver is a necessary evil for Windows users to unlock the hardware’s full potential. It works reliably once set up, but the lack of official support, installation hurdles, and power management bugs make it unsuitable for novices. On Mac, iPad, or Android, ignore the driver entirely — the dongle is a top-tier budget recommendation. On Windows, budget for 1 hour of tinkering and accept occasional replugging.
| Parameter | Performance | Notes | |-----------|-------------|-------| | | 1.1Vrms ~ 1.2Vrms | Slightly lower than Apple’s 1Vrms, fine for IEMs, weak for high-impedance headphones (>80Ω) | | Dynamic Range | ~118dB (A-weighted) | Excellent for the price | | THD+N @ 1kHz | ~0.0008% (32Ω load) | Clean, no audible distortion | | Output Impedance | < 1Ω | Ideal for multi-BA IEMs — no frequency response shift | | Jitter (12kHz J-test) | ~ -110dB | Very low, no spurious tones | mvsilicon b1 usb audio driver
