Beyerdynamic Premium DT 660 - Headphones ( ear-cup )

This is a truly great closed-back headphone with natural open and airy sound suited perfectly for large orchestras, chamber music, acoustic jazz etc. The isolation is really great both in and out. Compared to similarly priced closed-back ATH-M50 a lot better isolation. DT660 is very easy to drive. It sounds fairly good from an android phone and even better from a computer. The bass is much better when driven by a real headphone amp.

I bought the product 3 months ago.  Beyerdynamic DT660 Premium Edition is fantastic headphone.  Very natural sound for the price. İt has flat sound but dont tired of listening to music. May sound a bit harsh treble. Give yourself time to get used to your ears. According to closed headphones, with fairly large stage. DT660 has a larger scene and bigger than DT770. DT 660's isolation is considered good enough.
I would definitely recommend it for classical music, instrumental music, jazz and rock music...
