Adorable Earin A-3 True Wireless In-Ear Headphones are Sleek and Compact

Backed by the Kickstarter community in 2014, in 2015, Earin was the first company to introduce true wireless in-ear headphones with their M-1 earbuds, followed by the M-2 in 2017. For CES 2021, they’ve just announced their third generation of sleek, tiny, and innovative in-ear wireless headphones, the Earin A-3.

The Earin A-3 combines the Scandinavian design that Earin has become known for with the latest audio and wireless connectivity features; somehow, they have managed to do this while keeping them the smallest wireless earbud on the market.

Earin A-3 earpieces do not have a dedicated right or left earbud. Instead, their patented technology will automatically assign each earbud as right or left when either bud is placed in the user’s ear. You can even share an earbud with a friend for a mono listening experience together. The Earin A-3 uses an open design (which means there are no silicone or foam tips that have to be jammed into your ear canal), so they sit comfortably and ergonomically in the user’s outer ear allowing for natural ambient sound awareness.

Obviously, this means that the Earin A-3 aren’t noise-canceling, but that feature, while desirable at times, isn’t always ideal. With the Earin A-3, you can have a comfortable conversation with someone without having to remove the earbud (you’ll still want to turn the sound down, of course), and they offer additional safety due to awareness of the sounds around you when you are exercising outdoors.

The earbuds have an IP52 rating, so they are sweat-, water-, and dust-resistant. Each earbud has an intuitive touch interface so that you can have a seamless experience answering calls, playing music, and skipping to the next song. They also use voice recognition technology to connect you to your favorite virtual assistant, whether it be Google, Alexa, or Siri.

The Earin A-3 have customized 14.3mm speakers that they say move “move 20 percent more air than competitor brands, creating a more crisp and clean sound with deeper bass.” Earin A-3’s don’t have the “stem” that you typically see on wireless headphones; instead, Earin incorporates both a microphone and an accelerometer in each of the earbuds. They use an adaptive algorithm to monitor voice and background noises in real-time, and they remove ambient noise to give the highest-quality call experience, no matter the environment. Music will be paused when you remove the Earin A-3 from your ear due to the in-ear sensor.

The Earin A-3 in-ear wireless headphones use Bluetooth 5.0 with a Qualcomm QCC5121 MCU. Depending upon the environment, they can receive a Bluetooth signal from up to 75 meters (246′!) away from your streaming device. They use the SBC, AAC, AptX, AptX low latency Audio Codecs.

The included aluminum charging case will hold and charge the Earin A-3 earbuds when they aren’t in use. The Earin A-3’s get up to five hours of music and calls on their own, and the charging case gives them up to 30 hours of playtime.Earin A-3 True Wireless In-Ear Headphones

The Earin A-3 will be available in black and silver models for $199 in the first quarter of 2021; you’ll be able to find them on the Earin site and Amazon. A Limited Edition version will be available exclusively for the Earin Kickstarter community beginning January 14th.
