The size of the speaker is the same as original. Works with Wonderswan, Wonderswan Color, Wonderswan Color Crystal.

The sound quality and volume are also adjusted as the original.

If the console sound is low, it's usually not the speaker that's damaged. The issue could be many things such as the audio chip is damaged, power amplifier capacitance aging, and the volume adjustment knob becoming rusty. These reasons can lead to less than desirable sound quality.
