Bluetooth has basically been fully transformed into TWS true wireless bluetooth headsets, and even formed an industry trend centered on TWS. TWS earphones have sunk from the general 1000 RMB to below 500 RMB, and even the domestically produced TWS earphones have some active noise reduction functions of around 500 RMB.
However, there is a big difference between what enthusiasts play in the earphone industry and what ordinary consumers use. What are the differences between TWS earphones with a level of 100 RMB and TWS above 1000 RMB? Let’s take a look at the TWS Active Noise Cancelling Headphone ranking list.
In the mobile phone camp, it is divided into the Android camp and the Apple mobile phone. In the emerging headphone industry of TWS, Apple AirPods will also occupy 35% of the headphone market in 2020, and even become the top three products of Apple’s revenue.
What are the characteristics of AirPods? In the mobile phone industry derived TWS active noise reduction headphones, there is a saying: Active noise reduction headphones are divided into AirPods Pro and others. However, Sony, Bose, Sennheiser, etc. have all made great breakthroughs in active noise reduction.
AirPods Pro has a two-way microphone, supports transparent mode, and uses the H1 chip independently developed by Apple. In addition to noise reduction and enhancement of the microphone, it also has a lot of improvement in audio sound effects. A single full charge can be used for 4.5 hours, continuous battery life is 24 hours, non-heavy headset users, only need to charge once a week. Compatible with watches, tablets, computers and mobile phones at the same time, AirPods Pro is the highest-selling existence of Apple headsets.
As long as it is the audio industry, Sennheiser is inseparable. Sennheiser is also indispensable for TWS active noise reduction. Sennheiser Momentum TW2 supports bluetooth 5.1, has a single battery life of 7 hours, a charging case battery life of 21 hours, a 7mm micro dynamic driver, the bass can dive to 5Hz, and the treble can rise to 21000Hz. The earphones have LED indicators and infrared sensors, laser metal touch panels, active noise reduction MEMS, etc. It has a variety of shortcut keys, supports Android, is compatible with IOS, and is splash-proof.
It is not difficult to make active noise reduction, but the difficulty is to maintain high-fidelity sound effects in the case of active noise reduction. If for the active noise reduction effect, the result affects the sound effect, then the gain is not worth the loss. Sennheiser Momentum TW2 has made independent optimization in the sound adjustment after active noise reduction. Even in the active noise reduction environment, the sound effect is still “Sennheiser” .
As an upgraded version of SONY WF-1000XM3, the major change made by WF-1000XM4 is to support bluetooth 5.2, multi-band active noise reduction, integrated high-performance processor V1, and compatible solutions for wind noise and environmental sound. The independent chip of QN1e is developed for active noise reduction.
We all know that the lower the sound effect, the more susceptible it is to noise reduction. Sony uses a 6nm drive unit to generate high-precision signals in the low-frequency range, which enhances the low-frequency noise reduction performance and retains the sound effect.
The transmission rate of LDAC technology is 990kbps, which has 3 times the improvement of the transmission and decoding of high-definition audio than ordinary headphones. The sound engine adopts Edge-AI, which makes the wireless headphones have Hi-Res professional sound effects.
A single earphone can be used for 8 hours when it is fully charged, and 36 hours can be used continuously with the charging case. Under fast charging conditions, it can be used continuously for 1 hour after 5 minutes of charging. It is also worth mentioning that the Sony WF-1000XM4 adds a bone conduction sensor on the basis of microphone beamforming, and has enhanced the clarity of voice calls.
