Early 2017 (late 2016) TWS Bluetooth headset with Apple's AirPods headset on the market it was booming, led to all major TWS headset manufacturers followed up.
At that time, the TWS headphone front-end solution is relatively weak. Some products on the market can be said to be surprisingly high in bad reviews. Of course, it can't resist the enthusiasm of the boutique sellers and seize the wind.
The highest point of mouth. At first, people was only interested in the products of AirPods and Sony from TWS say NO.
After more than a year of precipitation, TWS4.1 TWS4.2 TWS5.0, until 5.0 Bluetooth, solved the other pain points of binaural calls. the spring of TWS headphones has come.
Climax: 5.0 Bluetooth Solution
1. What is the difference between Bluetooth 5.0 and Bluetooth 4.2?
Compared with the previous Bluetooth 4.2, Bluetooth 5.0 has longer transmission distance and faster speed. The theoretical effective distance is 300 meters, that means the whole family or the whole office.Mobile equipment can be connected stably. In terms of transmission rate and delay, there are also great improvements and optimization, which can make it possible for wireless device applications that need to transmit more information and respond faster.
4.1-4.2 TWS Pain Points Summary:
(1) Short Distance, Frequent Offline
(2) Pairing failure often occurs in the left and right ears.
(3) Single-ear calls (airpods support double-ear calls)
(4) Sound delay occurs when playing games.
(5) At the same distance, turn around and appear left and right Bluetooth signal carton
(6) High power consumption and short standby time
(7) Many functions can't be realized, such as touch control to adjust volume, up and down, and wake up siri.
5.0 Bluetooth TWS:
Bluetooth 5.0's high transmission bandwidth also makes it possible for TWS real wireless Bluetooth headset to make bilateral calls. In addition, supporting higher bit rate audio playback also requires the strong cooperation of major mobile phone manufacturers.
There are about 20 mobile terminals that support Bluetooth 5.0 on the market: Apple's iPhone 8 Meizu 16 plus millet 8, Samsung NOTE9. This has laid a solid foundation for the explosive growth of Bluetooth 5.0 product market in the coming years.
Recently, several Bluetooth TWS 5.0 have been tested, which greatly improves the sound quality, pairing experience and operation accuracy.
2. What kind of schemes do TWS 5.0 have?
1. BES Evergreen BES2300: Fully integrated adaptive active noise reduction scheme, supporting Bluetooth 5.0, LBRT low-frequency forwarding technology and dual-mode Bluetooth 4.2.
2. REALTEK Ruiyu: RTL8763B: Bluetooth 5.0, HFP 1.7, HSP 1.2, A2DP 1.3, AVRDP 1.6, SPP 1.2, PDAP 1.0, with binaural call function
3/ Airoha Loda AB1526P: It has built-in baseband and transmitter for high fidelity audio applications, supporting broadband voice defined by dual microphone for better noise reduction and echo cancellation performance. Support A2DP, HFP, HSP and AVRCP. AB1526P Embedded Serial Flash Memory
4/ Qualcomm Qualcomm Qualcomm CSR8675: For the first time, active noise reduction technology has been introduced into CSR chips, making it the first Bluetooth audio system-level chip integrated with ANC functions in the world.
Qualcomm Qualcomm Qualcomm Qualcomm QCC3026 supports Bluetooth V5.0 version, with enhanced Qualcomm True Wireless stereo technology, which can provide better performance support for Qualcomm aptX audio technology with lower power consumption and higher cost performance ratio.
5/Actions Core
Summarize the hot spots of explosives:
1. Active Noise Reduction TWS Headphones: Both BES and Qualcomm have active noise reduction companies, which are relatively expensive in cost. Noise reduction TWS headphones of all BES schemes on the market.
2 and 5.0TWS support dual headphone call function
3. TWS sound quality waits for most improvements. Airoha and Qualcomm all support high fidelity sound quality technology. Compared with Airoha's 5.0 Bluetooth on the market at present, there are already products on the market.
4. Little Tornado tells you that a TWS headset with password "moving coil + moving iron" is very popular in the Japanese market at present, and it only looks at Meizu's products on the market. Here we can see that the requirement for sound quality is gradually improved!!!
With the upcoming release of REALTEK's new solution. soon it will not have the difference of main channel VS minor channe. Bluetooth headset experience will become more and more approprite.
