Recently, the Voice and Image Recognition Product Quality Supervision and Inspection Center of the Tenna of the People’s Republic of China released the test results of the noise reduction ability of smart earphones. Only two earphones have passed the certification, namely OPPO Enco Free 2 and Xiaodu Active Noisy Smart Headphone Pro.
The test results show that the maximum noise reduction depth of the two OPPO and Xiaodu headsets are both up to 40db, and both support the noise reduction of three microphones, and the battery life is up to 30h+, which is consistent with the product promotion data.
The domestic noise-canceling headset market has expanded rapidly, and the active noise-canceling effects of different brands of headsets vary. In July of this year, CCTV’s “Weekly Quality Report” made a big hit on the earphone market and conducted risk monitoring on 60 pairs of active noise-canceling earphones from 47 companies. It turns out that 50% of noise-canceling headphones have insufficient noise reduction, and nearly 40% of products that claim to have noise-canceling functions do not support active noise reduction at all.
OPPO officially released the OPPO Enco Free 2 wireless noise reduction headphones in May this year. The headphones have a maximum noise reduction depth of 42dB and are tuned with Dynaudio. The OPPO acoustics team has passed thousands of real-person tests to customize the noise reduction ears.
In addition, OPPO Enco Free 2 is equipped with Bluetooth 5.2, three-microphone noise reduction, IP54 dust and water resistance, transparent mode, and music playback time up to 30 hours.
