I'm using Ultimate ears triple.fi headphones with N900 and I found this combo much better than N810 and also little better than N97. Can't compare to i anything though.

Those of you who wan't to have EQ should just buy decent headphones. EQ doesn't make music sound better it makes it always worse especially when you are using good headphones. I hope that EQ is not ever included in maemo devices by default.

Edit: N900 I'm using is a pre production unit. from the summit.
