Honor Black Technology's new TWS headset, how good is it?

When did you discover that TWS headphones have become the most used audio products in your daily office?

There are many types of Bluetooth headsets on the market today, and now there are more choices than the one that stood out at the beginning. But if you want to have a TWS headset with good appearance, sound quality, and functions within 1,000 yuan, the range of options is small.

On March 17, Honor’s domestic conference, in addition to the release of the high-end flagship Honor Magic4 series, also brought the Honor Earbuds 3 Pro, a TWS headset. According to Honor's official news, as of 24:00 on March 25, Honor Earbuds 3 Pro won the double champion of Bluetooth headset category sales and sales in the price range of 500-1000 yuan on JD.com and Tmall respectively.

So what makes it the champion of this price segment, let's take a look.

Body temperature detection

Honor Earbuds3 Pro is the world's first TWS headset that supports temperature measurement. It can continuously measure body temperature with a temperature measurement error of only ±0.3°C. When the user's body temperature is too high or too low, a reminder can be sent through a mobile phone or watch. Especially in this difficult time of the epidemic, it is possible to measure body temperature at any time while working and entertaining.

Intelligent noise reduction

As a true wireless noise-cancelling headset, the Honor Earbuds 3 Pro supports scene-based intelligent noise reduction (the noise reduction depth can reach up to 46dB), and can intelligently adjust the three noise reduction gears of mild/moderate/deep according to different noisy environments , to ensure that in different environments, intelligently determine the most suitable music experience.

Great sound

The most important core element of Honor Earbuds3 Pro is sound quality.

It is the world's first ultra-wide-band coaxial dual-unit TWS earphone with an ultra-large φ11 amplitude moving coil unit + an ultra-thin ceramic tweeter. The ceramic tweeter has always been a material that only appears in high-end Hi-Fi wired headphones. For sound units made of other materials, the high-frequency sound brought by the ceramic unit material is more crisp, bright, transparent and impactful.

This time, when applied to the Honor Earbuds3 Pro headphones, the combination of the dynamic coil + ceramic unit double unit makes a leap in sound quality, and brings the audience an excellent performance of high, medium and low frequency balance.

Without further ado, let’s learn about the TWS earphone treble compensation technology and ceramic unit with me.

At present, in the TWS earphone market, the product sounding units mainly include moving coil, moving iron, coil iron and emerging coil porcelain (combination of moving coil unit and piezoelectric unit).

The moving coil unit is an alternating current passing through the voice coil under the action of the permanent magnet to vibrate the sound membrane to produce sound; the moving iron is also similar.

The piezoelectric ceramic unit is an alternating voltage driven piezoelectric element with the underlying metal substrate to vibrate and sound, so in terms of response speed, the piezoelectric unit is incomparable to the moving iron and moving coil units. The energy conversion step of the moving coil and the moving iron is that the current is converted into vibration under the action of the magnetic field, and more energy is lost in the process.

The piezoelectric ceramic unit is an information function that uses the piezoelectric effect of piezoelectric ceramics to convert mechanical energy and electrical energy into each other. Just like a spring that can convert kinetic energy and potential energy into each other, it will deform when it is energized, so relatively speaking, the energy loss is very small, and the energy consumption is also very small.

Now the TWS headset manufacturers on the market will set the bandwidth at 20HZ-20kHZ when setting the headset parameters. In fact, the moving coil unit is far from this level. Generally, the moving coil unit will have great attenuation near 10k. The piezoelectric ceramic unit can maintain the attenuation at 15dB in the range of 30K, and can maintain the attenuation at 30dB in the range of 40K, which are impossible for the moving iron unit.

Because piezoelectric ceramics are metal substrates, they have high stiffness, high definition, and frequency extension is higher than the other two. It is for this reason that the low-frequency range has become the short board of piezoelectric ceramics. In the combination of moving coil unit + piezoelectric ceramic multi-unit, the moving coil is responsible for low frequency and medium frequency, and the piezoelectric ceramic is responsible for high frequency, which compensates for the lack of moving coil in medium and high frequency, and effectively improves the extension performance and music of this part. The ability to express details can bring a clearer and more transparent listening experience.

Take BPR10H0.3-5, a multilayer piezoelectric ceramic developed and launched by BESTAR, which has been deeply involved in acoustic components for many years, as an example. The extension makes the sense of hearing richer and softer, ensures that the roundness of the sound is not lost in the case of high resolution, and restores the sound more naturally; no frequency division processing is required, the circuit requirements are simple, and it can be perfectly matched with the moving coil; High stable reliability and consistency.

In addition, since the cost of piezoelectric ceramics is relatively lower than that of moving iron, compared with the current high-end earphones mainly based on moving iron units, with the application of piezoelectric ceramics, a high-quality earphone with an affordable price can truly be achieved. With the help of the coil ceramic multi-unit sounding unit, the sound quality meets the three-frequency balance, the bass and treble have a relatively good performance, and the sound is clear and clean, with a sense of hierarchy. I believe that in the future TWS headset market, the application of piezoelectric ceramics will be become the mainstream trend.
