Oppo introduced the Enco Air4s true wireless earbuds in China, providing active noise cancellation, dual-microphone call noise reduction, and a total battery life reaching up to 43 hours.
During the initial sale in China, buyers can purchase the earbuds for approximately $26.
Up to 32dB Active Noise Cancellation
Active noise cancellation of up to 32dB is supported by the Oppo Enco Air4s, which the manufacturer states can lower everyday sounds like traffic, conversations, and background music.
Users who prefer hearing their environment without taking off the earbuds can use a transparency mode.
The Enco Air4s rely on two microphones paired with AI algorithms during calls to lower ambient noise and boost voice clarity in loud settings.
Up to 43 Hours of Battery Life
A single charge delivers up to 12 hours of playback on the Enco Air4s when ANC is inactive.
Enabling active noise cancellation or transparency mode reduces battery life to roughly eight hours.
Total playback extends to 43 hours when using the charging case.
According to Oppo, a 10-minute charge delivers up to four hours of listening time, and TÜV Rheinland certification was granted to the battery, which reportedly keeps steady performance following 1,000 charging cycles.
IP55 Rating and Durability Testing
Dust and water resistance are provided by an IP55 rating on the earbuds.
Testing of the Enco Air4s was conducted by Oppo in temperatures as high as 55°C, and the charging case underwent more than 20,000 opening and closing cycles.
Falls from 1.5 meters were survived by the charging case during drop testing, and the earbuds underwent drop tests from 1.8 meters.
Price and Availability
An initial price of roughly $26 is set for the Oppo Enco Air4s in China.
This pricing places them below the Oppo Enco Air 5, which sells for $29.
