As I have seen from reading and watching many reviews of different products; we all have different tastes. Love it or hate it.
So, one headphone may suit you better than another.
One guy may think a headphone has a lot of bass, whereas another who has listened to a lot more will go "actually it doesn't have much bass at all compared to some others I've listened to".
Another may say "it sounds pretty neutral, and has an amazing sound signature", whereas another may think it sounds overly bassy, or overly done on the high end, resulting in a not so amazing sound signature.
That is why I guess I don't get now, wanting comparisons between products that are completely different to the one being tested.
You would have to litterally try them yourself to get a personal opinion of the two, or three you are looking at.
Or, as I have done, take the plunge, and if you enjoy them, thats great!
Why compare, if you enjoy them? That is what I think anyway now.
I personally wouldn't look at the mad dogs for all round use because I do not like the look of them. Does that make the headphone bad? No. It just makes it useless to my needs.
To answer your question though, the LP2's are meant to be less bassy than the LP's, but the M-100's are meant to have a better sound balancing, with more balanced mids and highs, that shouldn't (and I use the word shouldn't as I've explained, we all have different ears and preferences) blend badly, and should result in a pleasing high end portable headphone that offers clarity and substance over other headphones offering the same type of bass response. They do not use bass as a substitute for quality.
