The difference in bass between the JBL Charge 5 and the JBL Clip 6 lies mainly in the size and construction of the speakers.

- Size and design: The JBL Charge 5 is a larger and more powerful speaker, which results in a better bass response. The JBL Clip 6 is smaller and more portable, making it ideal for transport, but less powerful in the bass range.
- Speaker size: The Charge 5 has larger drivers which can produce deeper and more powerful bass, unlike the Clip 6 which has smaller drivers and therefore less bass performance.
- Power: The Charge 5 has a higher power output, which has a positive effect on the bass, while the Clip 6 has a lower power output and therefore offers less bass intensity.

Overall, the JBL Charge 5 offers better bass than the JBL Clip 6.
