Swedish company Earin has come up with the world’s smallest true wireless Bluetooth earbuds, the Earin A-3. The earbuds were recently introduced at the 2021 CES and as you might have guessed from their name, these are the company’s 3rd generation true wireless earbuds.
These miniscule earbuds measure just 20 x 17 x 15.8mm and weigh a feather light 3.5 grams. Despite’s their tiny sizes, each of the A-3 feature a fairly large 14.3 mm Dynamic Driver with frequency response of 20Hz to 20KHz. Yes, these tiny powerhouses pack quite a punch.
The Earin A-3 are also packed with a few other high-end features such as touch sensor controls, accelerometer for detecting right or left ear wear (you don’t have to worry about which earbud goes into which ear), proximity sensors for wear detection (auto turn off when you remove from your ears to save battery) and even hall sensors to detect the charging case.

The charging case fully charges the earbuds in 1.5 hours which gives about 5 hours of use. The charging case contains its own battery for additional charges. With the charging case, users can expect up to 30 hours of continuous use which should be sufficient for most if not all audiophiles. Last but not least, the case itself supports wireless charging as well as via USB-C.
