Wired In-Ear Headphones with USB-C and 3.5 mm

The Mi backwi-b800-08 is a wired in-ear headphone finished in black. It uses a USB-C connector and includes a USB-C to 3.5 mm adapter for broader device compatibility. An inline remote handles volume, track changes and call answering. Four driver units combine dynamic and balanced armature designs.

Four-Driver Hybrid Acoustic System

Each earpiece houses four driver units that blend dynamic and balanced armature technologies. The specification lists a frequency response of 10 Hz to 28 kHz and an input impedance of 32 ohms. Sensitivity and signal-to-noise ratio are both rated at 96 decibels. Total harmonic distortion is specified for in-ear use.

For Listeners Who Want Wired USB-C Audio

Buyers who need wireless connectivity or active noise cancellation should look elsewhere. The environmental noise cancellation works on calls via the USB-C link and through the included ear tips. Users requiring a Lightning connector or a purely analogue 3.5 mm cable without an adapter will need a different model.

Questions about this item

How does the 10Hz-28KHz frequency range translate to everyday listening?

The 10Hz-28KHz span covers deep sub-bass through to high treble detail, so you hear both the weight of kick drums and the air around cymbals without roll-off at either extreme.

What does the USB-C connector actually limit or enable for audio quality?

The USB-C plug carries digital audio to an onboard DAC, bypassing the phone’s analogue stage, while the included 3.5mm adapter keeps compatibility with legacy jacks.

Will the 0.8-ounce earbuds and supplied tips stay secure in smaller ears?

At 0.8 ounces each bud is very light, and the L/M/S silicone tips let you match the nozzle to your ear canal for a stable, isolating seal.
