There's an easy Mod that will dramatically increase bass sound quality.
The bass in these headphones can be greatly improved via a simple modification that takes about 5 minutes; no special tools or soldering required.
The hardest part of the mod for most people is removing the ear cushions. Here's a video from Sennheiser [youtube.com] that demonstrates how to do so quickly and easily.
