The verdict
The Beyerdynamic DT 1770 PRO MKII is quite expensive and has a unique sound, but some may find this an interesting option. Still, $600 is a lot to spend on closed headphones that sound like this for most purposes.
✓Liked: Comfort, Isolation, Removable cables, Durability
✕Could be better: Frequency response, Price
