Despite its small size, Earin has left out no core features. The A-3 provides touch controls for music and calls, as well as accelerometers to see which earpiece is in. Left and right are not pre-selected like most models – you can use any knob in both ears. The A-3 is also equipped with proximity sensors for in-ear detection. With an IP52 rating, these earplugs are resistant to sweat, splashes and dust, which should provide enough protection to wear during a workout.

As for battery life, Earin says you can expect up to five hours on the earbuds themselves. If you take the charging case into account, the company claims up to 30 hours total use. What’s more, the case supports wireless charging, so you do not have to grab a USB-C cable every time you need to refuel.
The A-3 will be available for $ 199 in Q1 2021. The earbuds are only available in black, but you can have the choice of black or silver for the aluminum chest of drawers.
