Live TWS 2
In terms of appearance, the vivo TWS 2 continues the features of its predecessors, the vivo TWS Neo and the vivo TWS Earphone. The ear handle is slender and the lines are rounded and smooth. vivo TWS 2 uses the in-ear design because of the need for active noise reduction. The in-ear design allows for \"passive noise reduction\

Although the vivo TWS 2 is small, its battery life is good. Compared with the previous generation, vivo TWS 2 battery capacity increased by 60%. Among them, the maximum single battery life of vivo TWS 2 after noise reduction is turned on is about 4.5 hours, and the maximum single battery life of up to 8 hours after noise reduction is turned off. With 505mAh battery capacity charging box, can achieve up to 30 hours of overall battery life, only facing commuting use, basically can maintain a week.
In terms of hardware configuration, vivo TWS 2 has a 12.2mm large unit built in. As a high-specification sound unit, it brings excellent sound quality from the physical level after being tuned by vivo. The DeepX 2.0 stereo sound technology can provide three different sound styles, such as overweight bass, clear voice, and clear treble.

With these three sound styles, vivo TWS 2 can be suitable for rock, vocals and other different music. Taking the overweight bass mode as an example, it mainly enhances the ultra-low frequency sound from 20Hz to 80Hz to enhance the sense of enveloping bass. Coupled with the sound insulation effect of earplugs, it can reduce the leakage of earphones to a certain extent, and then improve the immersion performance of bass.
In addition, vivo TWS 2 is equipped with a new DEEP-HD ultra-HD audio engine. DEEP-HD ultra HD audio engine is mainly composed of three technologies: transport protocol, radio frequency technology, codec. For these three technologies, vivo carries out targeted optimization.
First of all, comprehensively improve Bluetooth transmission efficiency. vivo generates a new transmission protocol QHS based on the existing Bluetooth protocol. Second, improve Bluetooth reception performance. vivo independently developed antenna technology to enhance the stability of the headset's Bluetooth connection in 360 degrees. Finally, the codec is reformed. vivo TWS 2 adopts Qualcomm QCC3046 Bluetooth main control chip, supports aptX Adaptive HD audio transmission standard, and can be adjusted according to the transmission environment to maintain the smooth listening of music.

In fact, active noise reduction is also the core selling point of vivo TWS 2, which provides 40dB flagship noise reduction depth, and also provides depth, regular and mild noise reduction modes, which can be switched to choose.
In the noise reduction test, vivo TWS 2 can better complete the noise reduction task in noisy scenes, and in all the in-ear noise reduction headphones in my experience, it can be crowded into the first echelon.
It is worth mentioning that vivo TWS 2 also supports intelligent dynamic noise reduction, which can dynamically adjust the noise reduction effect according to the surrounding ambient noise and environmental changes. The advantage of this is that the ear pressure can be reduced according to the different environment, while reducing discomfort.
Compared with similar headphones that start at thousands of yuan, vivo TWS 2 has set the price at 499 yuan under the premise of ensuring hard standards such as sound quality and noise reduction, which is a very competitive \"participant\" in the current TWS track.
