OPPO today introduced Enco Q1, the company’s first
Bluetooth noise canceling neckband headphones in China. The headphones come
with in-ear earbuds that is curved at a certain angle to fit the ears
comfortably. This comes after OPPO filed ENCO trademark last month. Brian Shen,
OPPO VP confirmed that it has 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.
Meanwhile, the internal microphone is used to create
the feedback loop of the feedback noise cancellation system. A filter is used
to minimize the acoustical signal near the microphone. The OPPO Enco Q1 will come in
Orange, Black and White colors. We should know more details and the price once
the headphones go on sale on OPPO Online Store in China in the coming days.
