Due to the particularity of Bluetooth headset, electromagnetic wave in your area may interfere with Bluetooth connection, and there is a difference in sound feeling between left and right ears. It is recommended that you pair up again. Please keep away from microwave oven, monitor and other objects with large electromagnetic interference when using.
5.3.5 Does the headset support AAC / SBC decoding？
This product can support AAC / SBC decoding。
5.3.6 Train station, high-speed railway station, substation, airport or some environment, headset listen to music button？
Under the strong interference environment, the RF performance of the headset is affected, which causes the headset to jam when listening to music. Bluetooth products all have this problem.
At present, there is no obvious difference in the anti-interference effect of the products in different environments. There is no problem in the office, coffee shop, home and other environment where the interference is not strong.
5.3.7 Double click the headset to always turn on the built-in music player？
When the mobile phone is on the desktop, the headset gives the command to start playing. The mobile phone may start its own player by default instead of starting a third-party app. (this problem is related to the design of the mobile phone itself. Different mobile phones may perform differently. Non OPPO brand mobile phones may have other settings.) please open the music player you want to use.
5.3.8 There is no problem with the sound quality when listening to music, but it becomes worse when playing games？
When listening to music, it starts A2DP protocol;
When playing the game, the Game App starts the HFP call protocol. When using the HPF protocol, the audio bandwidth is narrow and the sound quality is slightly poor;
5.3.9 Why is there no sound in one or two ears？
Problem :
When talking, listening to music and listening to wechat voice, the single / double ears are silent.
Cause of the problem:
1. touch Bluetooth switch of mobile phone by mistake, and turn off Bluetooth at mobile phone end.
2. due to the particularity of Bluetooth headset, your area is in a strong electromagnetic interference environment, and there will be silent situation.
3. you are far away from your mobile phone and exceed the effective transmission distance of Bluetooth.
Solution:
1. check whether Bluetooth switch on the mobile phone is off. If it is off, please turn it on immediately, and then it can be restored.
2. please keep away from microwave oven, monitor and other objects with large electromagnetic interference when using.
3. please put the phone and headset together and try to reconnect. If it cannot be solved, please close the headset into the box for 5S and then reconnect the cover.
4. if the above method is still unable to be solved, if the 4S is heard by the long ear in non music and call mode, the phone will be paired again to recover the sound.
If none of the above is possible, try to restore the factory setting or put the cover in the charging box for 30s before opening the cover.
5.3.10 Turn on the absolute volume of the mobile phone, turn the volume of the Bluetooth headset to the minimum, turn off the absolute volume function, and the media will play silently？
After the absolute volume function is turned off, if the media is silent, you can try to press the right earphone for a long time to turn up the earphone volume to the appropriate volume. The "beep" indicates that the earphone volume is adjusted to the maximum. Or disconnect Bluetooth and connect again. If the headset detects that the phone does not support absolute volume, it will turn up the sound of the headset.
5.3.11 The sound quality of listening to music is not good (official speech)
1. Due to the particularity of Bluetooth headset, the electromagnetic wave in your area may interfere with Bluetooth connection, and there will be silent and intermittent situation. Please keep away from microwave oven, monitor and other objects with large electromagnetic interference when using
2. Bluetooth audio coding format has a great influence on the sound quality. Please open the high-definition music button on your phone or set it to AAC coding format
3. The sound quality is also related to wearing. This type of earphone is semi-in-ear, which is not well worn, and the bass is more likely to leak. It is possible to wear the earphone to fit the amount of bass to the appropriate range
5.3.12 Listening to music doesn't feel like W31 (or other earphones)？
OPPO EncoAir / Play is a semi in ear earphone, while W31 (or other in ear earphone) is an in ear earphone. The former has no silicone earmuff, so there will be a certain degree of Air leakage, and the bass will be weaker than the in ear earphone. The silicone cover of the in ear earphone is relatively soft, which can closely fit the ear canal, with less Air leakage, and the bass will be fuller. However, the sound quality of OPPO EncoAir / Play is also professionally tuned by OPPO. The overall listening feeling is transparent and clear, and the voice is clear; The sound field is wide and the sense of space is obvious.
5.3.13 How to deal with the big noise and current？
1. Due to the particularity of Bluetooth headset, the electromagnetic wave in your area may interfere with the connection of Bluetooth, resulting in silent interruption. Please keep away from microwave oven, monitor and other objects with large electromagnetic interference
2. Because there are many high frequency signals and the characteristics of the circuit itself in the Bluetooth headset, there will be some background noise in the Bluetooth headset. Due to device differences, Bluetooth environment interference or packet loss, only a small number of earphones have obvious background noise. In addition, different people have different ear sensitivity, so a small number of people may feel this background noise. But the probability is very low. I'm very sorry for this situation.
5.3.14 Put the earphone into the charging box, but the display is still connected. The voice of the mobile phone cannot be played out
OPPO EncoAir/Play does not detect the wearing function. If the headset is put into the charging box, if the cover of the charging box is not available, the headset is still connected to the phone. If you listen to songs with your phone at this time, the sound will come out of the headset by default and will not be played from the speakers. The Bluetooth headset will not be disconnected until the headset is put into the charging box and the cover is closed.
5.4 Call / phone / voice assistant
5.4.1 How to use headphones to answer / end a call?

5.4.3 The caller hears little sound / the surrounding noise is loud / the effect of the call is not as good as that of the unilateral Bluetooth headset？
1. Due to the particularity of Bluetooth headset, the electromagnetic wave in your area may interfere with the connection of Bluetooth, resulting in silent interruption. Please keep away from microwave oven, monitor and other objects with large electromagnetic interference
2. The noise reduction of the call can eliminate the common noise in daily life. However, for some special scenes, such as the motorcycle with strong wind or fast driving, MIC acquisition effect will be interfered by wind pressure, and the noise reduction effect will be reduced. Please try to avoid using headphones to talk in places where there is strong Air flow. In addition, in the place where there are many people and noisy people, the noise reduction effect of the call will decrease. It is suggested that the volume of speech should be improved to ensure the smooth communication.
3. If the other party hears a small voice when making a phone call, please confirm whether only one headset is worn and the other headphone is not in the box. Try to put the other headset back to the ear to see if it can be solved;

When wechat / QQ voice is used, turn on the voice assistant and HFP protocol at the same time. HFP conflict results in the sound of earphone being played out. The same problem exists in the Air pods earphone, which cannot be improved at present.
5.4.7 How to deal with the microphone sound too small when joining the zoom meeting
Zoom conference is divided into mobile phone zoom and computer zoom. Computer zoom is divided into IOS computer zoom and windows computer zoom.
Cell phone zoom and IOS computer zoom use HFP protocol (Call Protocol), pick up from the microphone of the headset, if the sound is small, you need to check whether the microphone of the left and right ears is blocked or not.
Windows computer zoom uses A2DP protocol (Music protocol). It picks up sound from the computer microphone. If the sound is small, it needs to sound from the microphone close to the computer and check whether the microphone of the computer is abnormal.
5.4.8 Do you use headphones or cell phone microphones when recording video or audio
Different mobile phones and software have different settings when recording video and recording, depending on the specific scene you use.
When talking, listening to music, sending voice messages and video / voice calls through wechat, the microphone of the headset is used. When recording video and recording, the microphone of the mobile phone may be used.
You can test it in the following ways:
After the headset is connected to the mobile phone, turn on the recording software, and wear the headset to leave the mobile phone for a certain distance (about 3-5 meters) before recording. After stopping recording, check whether there is sound in the recorded video or audio. If there is no sound or the sound is not clear, the recording uses a mobile phone microphone. If the sound is clear, the recording uses a headset microphone.
5.4.9 Does earphone have noise reduction function?
Active noise reduction is not supported
Support the uplink radio noise reduction in the call, and adopt the dual microphone intelligent call noise reduction algorithm to effectively reduce the surrounding noise and bring clear call effect.
