Pros: Soundstage, detail, bass, fun
Cons: need burn in
Just a quick review.
A local dealer closed his shop and sold off his Beyerdynamic stock for very attractive prices. I couldn't help and purchased a T50p and a DT 880 Premium from him.
I never owned a Beyerdynamic before, but Sennheiser, Ultrasone, Shure, Ultimate Ears, Koss etc. and finally wanted to find out if the "Beyer" sound is something for me.
In short: yes it is and I can highly recommend these headphones to everyone who looks for a all in one headphone. It's engaging, fun, crisp and detailed and has a nice soundstage. And it has a very nice sounding bass.
I am running them on various DACs and Amps but my preferred combination is a Griffin Powerwave as DAC (yeah it's old but I love it's sound) into a Schiit Valhalla.
For me, it's close to perfect actually.
