Review on 🎧 Beyerdynamic DT 770 PRO 250 Ohm Over-Ear Studio Headphones in Black Bundle: Blucoil 6' 3.5mm Headphone Extension Cable, Slappa Full-Sized HardBody PRO Headphone Case by Latoya Harper

Excellent! Incredible sound! I've never heard headphones that can be as good as my hi-fi system, but these come close or even better in many ways. You have to give it some power though! It was awful on my phone obviously at 250 ohms, on my custom headphone amp capable of putting out 114mW into 300 ohms, it's crazy insanely good. However, the extra cable that comes with it is bad, creates glare and ruins the sound, I think due to too much resistance in the cable or too long. The case is good. But with headphones, WOW!
