T2 - FAQ - I can't be heard well during calls, what should I do?

If the person you're having a phone call with cannot hear you well, there are several different factors that could be causing this. We'll guide you step-by-step to localize the issue and outline which factors you can and cannot affect.

Check the hardware

One of the first things to check is if the earbuds (where the microphones are placed) are dirty or if any of the ports are obstructed. If you notice any dust or dirt on the earbuds, gently remove it.

Avoid windy or loud environments

While the beamforming microphones aid in canceling out any outside noise, it's always best to check if the sound quality improves in a more quiet area, whenever possible. 

Pay attention to how the earbuds are worn

Keep in mind that the T2 microphones are tuned to listen for speech from a certain direction and distance, approximately from your ears (where the earbuds are placed) to your mouth (where your voice is coming from). Make sure to fit the earbuds so that the pointy end (where the microphones are located) is aligned with your mouth. Wearing the earbuds incorrectly or using one earbud at a time can affect the sound quality of your voice. If you prefer using only one earbud, make sure to keep the other one inside the T2 charging case in the meantime.

Record your own voice

The next step is to check if the issue lies in the microphones. Using your paired device, make a recording of yourself talking. Examples of this are using the built-in camera or a voice memo app.

If your voice sounds good during the recording, you can rule out issues with the microphone.

Charge the battery

Phone calls and VoIP calls use more battery than with normal playback, considering that both the speakers and microphones are used at the same time. You may experience poorer call quality if your earbuds are low on battery. 

Check for signal interference

Glitching, distortions, delays, and other sound issues during a call are most often caused by interference, either from other Bluetooth devices nearby, Wi-Fi networks or cell reception. While localizing the source of the interference can be tedious and time-consuming, it will help you single out which devices are affecting the sound quality.

The best way to determine the source of the interference is by ruling out each scenario one by one while on a call with a helpful friend. As a rule of thumb, always perform a factory reset on your T2 if you're experiencing connection issues. Then, with each completed step below, check if the sound quality changes.

• If you have any other Bluetooth devices connected to the same device that your T2 is paired with, such as other wireless audio products, smartwatches, keyboards, mice etc., disconnect all but T2. If you notice a difference, you can then pair each device again one by one. 
• If your device is connected to a Wi-Fi network, disconnect it and check the call quality again. If the sound quality improves, your Wi-Fi network may be using the same frequency as the T2 earbuds or the paired device. You can possibly overcome this by moving closer to your router, or by changing the channel in your router settings. Refer to the manufacturer's documentation for more information.
• Other physical objects in your vicinity can also cause interference, including (but not limited to); walls, large solid objects, jewelry, metal objects, microwaves, or any object that emits frequencies of 2.4GHz.
