February 16 news, Sony LinkBuds true wireless headphones, with a new type of ring driver unit, support wide-area click control, do not support noise reduction, pre-priced 1199 yuan.
The main feature of LinkBuds is the large driver unit, which is hollow in the middle, so you can clearly hear the outside world when listening to music. Xiao Lei uses the AirPods Pro, and its transparent mode can clearly receive the sound of the outside world. Therefore, the selling point of LinkBuds and some competitors do not form an advantage.
Critical to call quality, Ray only saw a microphone outside of LinkBuds. Sony said that LinkBuds intelligently eliminates ambient noise by intelligently identifying human and ambient sounds, so that devices can have higher call quality. This requires the device to be able to process the recorded sound information in real time and process it with low latency.
It must also ensure that the human voice and ambient sound can be accurately identified, Xiao Lei is skeptical of this, Xiao Lei suggested that after the small partners measured, they can have a clearer judgment on the level of call noise reduction.
So how does AirPods Pro deal with call noise reduction, its exterior has a main microphone, a small microphone at the bottom of the headphone handle, dual microphones to form beamforming, the time for sound to reach the two microphones is inconsistent, AirPods Pro can identify the source direction of sound. When on a call, airPods Pro amplifies the sound in the mouth and lowers the sound in other directions.
For the anti-wind noise ability, the official publicity interface is not introduced. AirPods Pro is by adding a net at the microphone, Huawei's high-end headphones are designed in the microphone to design a zigzag channel inside the microphone, in order to reduce wind noise. LinkBuds' wind noise resistance needs to be further disassembled.
One of the features of LinkBuds is that it can control the headphones by tapping on the pinna. Xiao Lei has always believed that tapping the headphone body is a relatively poor way of interacting, which will squeeze the ear canal and produce noise. Moreover, when tapping the headset body, the accuracy of recognition is not high, and the use experience is poor.
In addition, the headset also has an adaptive volume control function, which can intelligently adjust the volume according to the external environment, Xiao Lei feels that this is a very convenient function, and other brands can also learn.
