Mi Puremic 668 ME537 USB-C In-Ear Earphones

These wired USB-C in-ear headphones include a built-in DSP chip and premium metal microphone for clear calls and HiFi stereo sound. They suit streamers, singers and gamers who want plug-and-play audio with passive noise cancellation and a retractable cable. The hybrid driver design supports multiple modes including live streaming, karaoke and music listening switched by a single multifunction button.

USB-C wired connection with Bluetooth pairing limit

The earphones connect to a host device through the USB-C port for audio and power, while a secondary Bluetooth link can pair a second phone for background music during a stream. This dual-device workflow requires one phone cabled and the other paired wirelessly to the Pure668 profile; it does not replace a standard standalone Bluetooth headset for everyday wireless use.

70 dB signal-to-noise ratio decides fit

A 70 dB high SNR suppresses background noise for crystal-clear calls and lossless HiFi stereo performance. Buyers who need a higher SNR for professional studio recording or broadcast-grade voice capture should look elsewhere. The single-ear coupling and 0.13-pound weight complete the specification that determines whether this model matches the intended use.

Questions about this item

Which model number should I choose between the ME537 and the Puremic 668?

They are the same product — ME537 is the part number and Puremic 668 is the marketing name.

What does the 70 dB signal-to-noise ratio mean for my recordings?

It indicates a very low noise floor so vocals and instruments come through cleanly without audible hiss.

How does the USB-C connection limit what I can plug these into?

They only work with devices that have a USB-C port supporting digital audio output.
