1. Make sure your earbuds fit your ears correctly and that you have a good seal
The most important factor in making sure that your earbuds fit correctly and that the sound (especially bass) is optimal, is choosing the correct size ear tips for your ears.
The M100 comes with small, medium, and large silicone and small and large foam ear tips included. We would recommend trying the full range of tips provided, so you can find the right fit for you.
When trying the foam tips, we would suggest fitting them by following the steps in the image below:
2. Remove any custom or preset EQ settings that may be configured
This includes any settings in the Melomania Connect App, for the device itself and the app used to play audio. EQ settings may alter the sound of your M100 earbuds.
3. Try playing from a different source device and app to see whether there is any difference
4. Perform a factory reset on the M100
You can perform a reset on the ear buds by following the steps in the Melomania Connect app User Guide or the FAQ here.
