The SE210's are not warm. They just have very rolled off treble, and I wouldn't say they have much bass either. They have very forward mids and that's the bulk of the sound signature. The highs are hard to hear and the bass is as well. Now, if you consider just mids to sound warm then I guess they are, but I wouldn't recommend them unless you want to focus only on mids as that is about all they do well - aside from isolate.
