The Anker AeroClip 2 has an open-ear design, so you can take calls and still hear what's going on around you. If you notice call-related issues with your AeroClip 2, such as unclear calls, missing ringtone, or no sound during calls, the cause may be related to fit, wearing status, call routing, or device settings.

If My Voice Sounds Unclear on Calls

First, check whether the other person cannot hear you clearly, or whether you cannot hear them clearly. Then try the following:

• Make sure the earbuds are worn on the correct side and facing the correct direction. Wearing the left and right earbuds incorrectly may affect both call clarity and voice pickup. Also adjust the wearing angle so the sound outlet sits closer to your ear. If it is too far away, call audio may sound weak or unclear.

• If you are using only one earbud, place the other earbud in the charging case and close the lid. When both earbuds are out of the case, the microphone is normally activated only on the primary earbud. If the unused earbud remains outside the case, the microphone may not switch correctly to the one you are wearing, which can make your voice sound distant or unclear. 

• If you are using a computer for calls, please also check whether your calling software is using AeroClip 2 as the microphone input device. Some calling applications do not automatically switch to a Bluetooth device as the default microphone. If AeroClip 2 is not selected as the input device, the app may instead use another connected device or the computer’s built-in microphone. In that case, the microphone quality heard by the other person would not actually be coming from the earbuds.

The exact steps may vary depending on the calling software you are using.

• If you are using an iPhone, where the call audio plays may depend on how you answer the call. If you answer the call on your phone, the audio may default to the phone’s speaker instead of the earbuds. To route call audio to the earbuds, go to Settings > Accessibility > Touch > Call Audio Routing and select Bluetooth Headset.

• If you are using an Android device, go to Settings > Bluetooth, find Anker soundcore AeroClip 2, tap to view its settings, and make sure Call Audio is enabled.

• Check whether the microphone opening is blocked. The microphone is located near where the battery housing connects to the C-shaped bridge. Clean this area if needed.

• Place the earbuds in the charging case and keep the lid open. Press and hold the case button for more than 10 seconds until the indicator flashes red three times quickly. This confirms that the factory reset was successful. Tutorial video: https://www.youtube.com/watch?v=2LbP1Y7Y11g 

• Move to another location to rule out possible signal or environmental interference.

• Call a different contact to check whether the issue may be related to the other party’s device or connection. If the other person is also wearing earbuds during the call, ask them to remove them and try again.

If the Microphone Is Not Working During a Call

If the microphone is not working during a call, you can also try the following steps in addition to the troubleshooting suggestions above: 

• Make sure your calling app is allowed to use the microphone and Bluetooth.

• If you are using a Windows 10 computer, use Hands-Free mode instead of Stereo mode for calls. Stereo mode usually supports better audio playback, but it often does not support microphone input. Hands-Free mode supports both calling and microphone use, although the sound quality may be lower. 

• If the problem happens only in one calling app, or still continues after the steps above, the issue may be related to compatibility with that app. In that case, please contact us and include your device model and calling app information so we can help check it further.
