DT-1770 Pro 250 Ohm : A high-quality headphone.

Well built feels very sturdy and is of high quality. The detachable cable is excellent since if I accidentally break the connector as I've done with one of my other headphones, I can replace the cord instead of having to replace the whole unit.

These headphones don't have active noise cancellation and rely on sound isolation. The sound isolation on these headphones is very good, it blocks out a great deal of sound, and the sound it fails to block out is at least greatly subdued.

I found the audio itself to be very enjoyable. I won't delve into the technicals as I simply lack the knowledge to (I'm not much of an audiophile). Though out of the headsets I've owned (DT-770 pro and the Fidelio X2HR) I enjoy these the most, the bass feels powerful and the vocals are clear.

The case is a nice added bonus, not of much use to me, but I can imagine how it can come in handy to others. Two cables are provided with the headphone, one where the cable is spiralled and one standard cable.

Overall well worth the purchase.
