TWS is the abbreviation of true wireless stereo, which means true wireless stereo. The realization of this technology is based on the development of chip technology. Technically speaking, the mobile phone is connected to the master speaker, and then the master speaker is connected to the slave speaker through Bluetooth wireless mode to realize the real Bluetooth wireless separation of the left and right channels.
When the slave speaker is not connected, the master speaker returns to mono sound quality. TWS technology was applied to the field of Bluetooth headset, so a new product-TWS Bluetooth headset was born, the most famous of which is Apple Airpods. Since the release of Apple AirPods, consumers have really begun to pay attention to the category of wireless headphones.
Buying points:
1, chip
At present, the mainstream chip schemes are Qualcomm, MTK, Zhuorong, Torch Core and Hengxuan. The best scheme recognized by the industry is Rhoda, and Rhoda's current TWS scheme is basically the best scheme of 1536.
2. How to wear it
At present, there are two mainstream TWS, one is the non-in-ear type represented by airpods, and the other is the in-ear type. Because the in-ear type can isolate external noise and prevent air leakage, the bass effect is very good. So under the same conditions, the in-ear sound quality is better.
3. Bluetooth transmission protocol
Due to the bandwidth limitation of TWS, LDAC and APTXHD have not been applied to TWS at present, and even QCC5 12 1/24 in Qualcomm cannot support them. Therefore, there are currently three mainstream TWS, single board computer, AAC and APTX. The worst sound quality is SBC and the best is aptX.
