Are you looking to improve the bass quality of your soundcore K20i earbuds? Look no further! In this article, we will provide you with tips and tricks on how to enhance the bass quality of your earbuds and take your listening experience to the next level.

Knowing that if the audio source doesn't have much bass, the earbuds will have poor bass. To confirm the problem, please try the following troubleshooting:

1. Make sure the charging case has enough power and reset the earbuds by following the steps below:

  - Put the earbuds into the charging case and then take them out. Make sure that the earbuds are connected to the charging case. If you place the left and right earbuds in the charging case and the LED indicators on the charging case light up for 4 seconds and then go off, it means they are connected properly.

   - Within one minute of the earbuds powering on, tap and hold the touch area--top of the earbud stem on both earbuds for 10 seconds until you hear a notification sound.

2. Try different types of music and turn up the volume on the connected device to see if it helps at all.

3. Turn the earbuds while wearing them to find the most comfortable position. This will enhance the sound quality. 

4. Try selecting "Sound Effect" in the soundcore app and choose the "Bass Booster" or "Bass Reducer" EQ from the 22 available EQ options.

5. Try selecting the "Custom EQ" option in the app to customize the EQ curve style.

6. Try using your earbuds with a different Bluetooth device to see if there is a difference.
