I've never tried the DT660, but I know it was not the best model in the earlier series that Beyerdynamic made for consumers, with the DT770, 880 and 990 being considered by Beyer as the superior models. That said, most people who own the DT150 consider it better than the DT770-990 series, because it has more controlled highs and better vocals, especially male vocals. If you listen to Electronic music, perhaps the DT660 will be better, but I think for most genres of music the DT150 is better, and it's closed, so you block out some noise. The problem is that you will probably need an amplifier for the DT150, and also they are not really portable. You may also find the DT660 to be more comfortable, especially if you wear glasses.
I'm looking for an IEM that sounds like the DT150, with perhaps even tighter bass and a more even upper mid-range. Has anyone tried the Westone UM Pro 50? From the descriptions I'm reading it seems to fit the bill.
Thank you, jdpark
I have an er4s paring up with Mojo, which is wonderful but not good for orchestral music. I think I will give DT150 a try
