Will the Wireless Earbuds Replace the Wired?

Will the Wireless Earbuds Replace the Wired?

At present, there are two main ways for TWS earphones on the market to realize the in-ear detection function. One is that the capacitance scheme is to determine whether the earphone is in the ear by sensing the capacitance value of the human body. The other is the optical detection scheme that uses a VCSEL laser transmitter and a 940nm infrared laser proximity sensor to determine whether the earphone is in the ear.

Compared with the capacitance detection solution, the optical detection solution has the advantage of higher accuracy. Branded headsets pursue higher detection accuracy and better user experience, and tend to use optical solutions with a lower misoperation rate, giving consumers a feeling of "only flagship products".

From the two perspectives of continuously reducing technology development costs and product upgrades, the optical in-ear detection solution will be adopted by more products in the future.

For low-end price-sensitive people, it is clear to everyone that a headphone cable and an entire Bluetooth module are cheaper. The headset cord will be disconnected, and the Bluetooth headset will also malfunction. Delay and connection stability can see a glimmer of light, but at present, only a few of Apple's own solutions can compress the delay to less than 100ms, which may still be difficult for fps and audio game players who are extremely delay-sensitive. Accepted. For high-end headset players, the small size, high battery life, and low latency of Bluetooth headsets basically all conflict with the sound quality requirements. At present, the true high-end headphones and audio listening systems do not use Bluetooth, and at most use Bluetooth for control.

So wireless and wired earbuds are necessary for different groups of people, and they will all exist.
