Despite the small size, Earin did not omit any major features. The A-3 offers touch controls for music and calls along with accelerometers that detect which ear the headset is in. Left and right are not pre-selected like most models – you can use any button in any ear. The A-3 is also equipped with proximity sensors for detection at the ear. With an IP52 rating, these headphones are resistant to sweat, splash and dust, which should be enough protection to use them during a workout.

In terms of battery life, Earin says you can wait up to five hours on the headphones themselves. When you consider the charging case, the company claims up to 30 hours of total use. What’s more, the case supports wireless charging, so you don’t have to take a USB-C cable whenever you need to refill.
The A-3 will be available in the first quarter of 2021 for $ 199. The headphones are only available in black, but you can choose between black or silver for the aluminum charging case.
