4Mic FF+FB double active noise reduction" is "four microphones, feedforward + feedback mixed noise reduction". Active noise reduction can be divided into feedforward (Feed Fore) noise reduction and backfeed (Feed Back) noise reduction. At present, many noise reduction headphones only use FF noise reduction, double noise reduction after double "filtering" will be more thorough.
This headset is officially online, using collar design, neck ring with streamline Radian, three-dimensional curve to fit the neck. Integrated molding technology, no splicing gap. Ergonomic earplugs fit the ear canal. In terms of color, black, white and orange are optional.
In July, some foreign media exposed OPPO Enco, and released its patent map. The documents, from the European Union's intellectual property Agency, show that OPPO was granted a new trademark right on July 2-ENCO, which was speculated by the media at the time, was likely to be its folding screen series. The unintended ENCO was used on the first wireless noise reduction headset.
At present, the headset is not yet on the OPPO website, the launch time, price are unknown.
Shen Yiren has just announced wireless noise reduction headphones have aroused widespread concern among netizens, some netizens can not wait to ask Shen Yiren when this noise reduction headphones will be released, how much is the price?
In this regard, Shen Yiren has not yet made a reply.
But earlier this month, Shen Yiren, vice president of OPPO, said that the chances of OPPO watches this year should be none, and there is a good chance that they will have a good chance of reducing noise and hanging headphones this year.
At present, Sony and BOSE noise reduction headphones dominate the market. OPPO, a self-developed noise reduction headphone, must work hard on noise reduction effect and sound quality if it is to stand out. In addition, it is also a good selling point to improve the sound quality and reduce the delay by adjusting the OPPO mobile phone.
