 4. The verdict of  OPPO ENCO Q1 wireless headphones

  • OPPO ENCO Q1 wireless noise reduction headset is designed with a flexible integrated neckband that is lightweight and comfortable to wear.
  • OPPO Enco QI  adopts four microphones for both FF+FB dual active noise cancellation. This Hybrid active noise cancellation uses both feedback and feedforward using four microphones, one pair per side. The feedforward active noise cancellation uses the external microphone to measure ambient noise before it enters the ear, processing that signal to ensure an exact and opposite signal leaves the system’s speaker to effectively cancel the ambient noise.
  • The PEEK+PU composite diaphragm large-size dynamic speaker quipped deliver us very good sound performance. 
  • Built-in BES2300 digital chip, which is a new architecture of digital noise reduction chip, is capable of real-time calculation and processing of noise signals, and it works with the built-in ENC environment noise reduction algorithm to eliminate noise more accurately and effectively.
  • The power consumption of the chip in music mode is less than 5mA, and in combination with the built-in 160mAh lithium battery, it brings us 15 hours in noise-canceling mode and 22 hours in noise-canceling turnoff.
