Just got my N900 a day ago ... have been listening to music on it now. The N900 speakers are pretty loud and clear by itself.

But I thought I would play my music on my older N810 on Canola.

Side by side, the N810 wins hands down - much deeper sound and more filling rather than the slighly tinny sound on the N900.

The N900 sounds much better than my wife's 5800 - but the N810 is certainly better - of course the N810 is a bigger device and thus more space for better speakers.
