OPPO ENCO Q1 Noise Canceling True Wireless Earbuds Teardown | Hifigo

After the official announcement in India and Shanghai, OPPO ENCO Q1 went on sale since September 12th.  OPPO Enco Q1 wireless headphones are the company’s first Bluetooth noise-canceling neckband headphones. We got OPPO ENCO Q1 from the first batch and we are very curious about the details inside.

1. Unboxing of OPPO ENCO Q1 wireless headphones 

The headphones we got are sunny orange version. 

Frontpage of the box showing it is a neckless headphone directly. 

There are so many details at back: active noise reduction, excellent sound quality, ultra-long endurance, comfortable wearing, etc. The sticker on the back shows the most important parameters.  

The package includes headphones, charging cable, extra three orange liquid silicone ear tips in different sizes, warranty card, and quick guide.

USB-a to a usb-c white charging cable. 

Translucent orange liquid silicone ear tips are similar in color to the sunny orange earphone.

There is a working indicator LED between the volume button and the multi-function button.

 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.
