Frequently Asked Questions
-
How can the volume be changed on my TWS earbuds?
STEP 1: Verify that your phone and the i12 TWS are correctly connected. STEP 2: Verify that silent mode is not activated on your phone. STEP 3: To start the music, simply click once on the i12 TWS. Step 4: To lower the volume, double-click on the right earbuds. -
Why do my earbuds only function on one side?
Depending on the audio settings on your headset, it might only play in one ear. So, make sure the mono option is off in your audio properties by checking your audio properties. Make sure the voice levels on both earbuds are balanced as well. -
Why won’t my earbuds link with one another?
If the battery in your headphones is low, they might not be able to pair. Additionally, I’ve discovered that certain Bluetooth headphones stay on when in the case, which causes them to deplete to zero percent more quickly than you would expect. Even if they claim to have some battery left, try plugging them in and giving them a thorough charge before pairing. -
Why won’t my Bluetooth earbuds pair with one another?
Your device’s Bluetooth setting should be disabled. Earbuds will automatically turn on when you remove them from the case. To manually sync them, double-press the left and right earbuds at the same time. NOTE: Give it another shot if it doesn’t work the first time. -
Why isn’t working one of my Bluetooth earbuds?
Restarting the headset is the first step to solving a Bluetooth earphones issue. If that still doesn’t fix the issue, try pairing and Bluetooth reset. If it doesn’t work, check the audio settings on your phone or computer. Otherwise, we believe your sound is the cause of the issue. -
Why is the volume on my earbuds so low?
You may adjust the volume on your Android device by pressing the “volume up” and “volume down” buttons until it is loud enough for you to comfortably hear. Go to Settings > Sound & vibration if it doesn’t work or if you want to access your settings and change other audio settings. -
Why won’t my TWS pair?
STEP 1: Remove the pairing information for the left and right earbuds (Reset the i12 TWS). 5 Press the power button while in pairing mode until the LED turns red. STEP 2: To activate the i12 TWS, long press the function key for 5 seconds. STEP 3: Start the pairing process. The pairing process takes roughly 5 seconds. -
Why is the volume on Bluetooth so low?
This is due to Android’s relatively low maximum volume restriction for Bluetooth devices. It was implemented as a safety measure to shield us against any hearing issues in the future. Additionally, the separate volume control sliders for Bluetooth devices have been abolished in the new Android versions, namely Android 7 (Nougat) and above. -
Can you adjust the volume on earbuds?
While typical wireless earbuds with an audio cord connecting two earpieces include integrated volume controls, true wireless earbuds have touch-sensitive or conventional buttons on their housings. -
How can I make my Bluetooth earbuds quieter?
Two volume controls are available with a Bluetooth headset: one is located on the phone’s buttons, and the other is located on the headphones themselves. Try adjusting the controls on both.
