<kse:widget data-widget-type="customText" id="1005000018472001" type="custom"></kse:widget>Q1: About OnePlus Buds 4 LHDC5.0A1: High-quality Bluetooth coding LHDC needs to be supported by both the mobile phone and the headset before it can be used. Non-OnePlus/OPPO need to use high-quality Bluetooth coding, and the mobile phone must support LHDC. LHDC5.0 of OnePlus Buds4 is not backward compatible. If OnePlus/OPPO mobile phones need to achieve the effect of LHDC5.0, they must ensure that the mobile phone supports LHDC and the system version is ColorOS131 and above: Whether other brands of mobile phones support LHDC5.0, please consult the corresponding mobile phone manufacturers. Q2: Does the full-scene spatial sound effect support the head tracking function?A2: OnePlus Buds4 only supports fixed spatial sound effects, regardless of mobile phone devices. But it does not support head tracking spatial audio function. Q3: What is Adaptive Mode? What if Adaptive Mode does not meet my requirements?A3: Adaptive Mode integrates active noise reduction and transparency mode in real time, and controls the noise level in the headphones according to the changes in the ambient noise. When you are in a noisy environment, the noise reduction function will be activated; when the surroundings are quiet, the headphones will let the ambient sound in, giving you more comfort. Application scenarios: ① Daily travel: When walking or riding a bicycle on the road, in order to make you safer, keep attention to the ambient sound. Adaptive mode can reduce the low-frequency noise generated by cars on the road, such as tire noise and engine noise, while retaining the mid- and high-frequency sounds such as horns and people's voices in the environment. ② Office environment: In the office, the adaptive mode can automatically adjust the degree of noise reduction and transparency according to the changes in ambient sounds such as the conversations of colleagues and the noise of office equipment. When the surroundings are relatively quiet, appropriately reduce the noise reduction intensity so that users can hear colleagues' calls or important work prompts: when the environment is noisy, appropriately enhance the noise reduction effect. Suggestion: If the effect of adaptive mode does not meet your expectations, you can manually switch to noise reduction or transparency mode; for example, if you want to experience a deeper noise reduction effect in a noisy outdoor or quiet environment, you can manually switch to noise reduction mode. Q4: How to connect a second device? A4: Please follow the steps below: 1. Put the earphones into the charging case, open the charging case, press and hold the button on the side of the charging case until the indicator light on the front of the charging case flashes white, and the earphones have entered the pairing state; 2. In the Bluetooth menu of the second mobile phone, computer, Pad and other devices you want to connect, find the device name of "OnePlusBuds4" and click pairing; 3. After pairing is successful, the earphones are connected to two devices at the same time. When you need to switch the device to play, please pause the device that is currently playing the sound. Q5: Why is there no personalized noise reduction?A5: - Buds4 uses real-time active noise reduction technology, which is a comprehensive upgrade of the "personalized noise reduction" solution. It not only plans the ear canal type of the crowd, but also detects the ear canal type of each user in real time, as well as the current environmental noise, and calculates the most suitable filter solution, greatly improving the noise reduction effect of each user in each scene.
