STA m73 Bluetooth 5.3 earbuds 34 h IPX7 black

Ready for daily use

The STA m73 are in-ear wireless earbuds with Bluetooth 5.3 connectivity and a stated 34-hour total operating time including the charging case. They target commuters, gym-goers and anyone who wants cable-free audio for calls, music or video on Android and iOS devices. An IPX7 rating means they survive sweat, rain and accidental splashes without damage.

Simple pairing and fit

Open the case and the earbuds enter pairing mode automatically; the USB-C cable recharges the case in a single session. Four built-in ENC microphones filter background noise during calls, though wind rushing past the stems can still be audible at speed. The protein-leather tips come in one size, so users with very small or very large ear canals may struggle to get a secure seal.

Steady output for long sessions

The 14500 cell inside the case delivers the advertised 34 hours of combined playback at moderate volume, and the LED display shows remaining charge in ten-percent steps. Bluetooth 5.3 maintains a stable link up to the quoted 66 ft indoors, but concrete walls cut the practical range roughly in half. Audio quality stays consistent until the final ten percent of case capacity, when volume may dip slightly to preserve battery health.
