They are better than the HD25 and the Momentum, IMO. The HD25 and the Momentum have more mid-bass, but the Mikros has more sub-bass...and the bass in general is more balanced and refined. The DT1350 and the Mikros are very similar - I own and love both models. The Momentum replaced my HD25...and I sold my Momentum after I bought the Mikros (the Mikros unexpectedly replaced the Sennheiser).
I don't think the Mikros blows the Sennheisers out of the water, but the ML is better (IMO). I would probably chose the DT1350 over the Mikros because the Beyer has some of the best bass in the business. The M90 has a wider soundstage than the DT1350, so it's a close call.
The Momentums are really comfortable -- I wish an over the ear Mikros existed.
^ What is this blasphemy you speak of. There will only be ONE love and ONE Mikros, nothing else you herrrr???!!! Or else........
