I Have several nc headphones an really loving the comfort, sound, noise cancelling and sound of this headphone and the refurbished price. recommened!
Sie gefallen mir sehr gut.
Der Klang ist sehr gut. Ein bisschen zu klar für meinen Geschmack, aber wer klare Kopfhörer sucht, die Musik so wiedergeben wie komponiert wurde, der wird hier fündig.
For this prise, you can't let it go.
Sennheiser pxc550II here, refurbished. Overall very good condition, just a little bit worn earpad.
Too bad their replacement parts store doesn't work, I can't buy new earpads...
Extremely comfortable, very good Bluetooth connectivity and excellent noise cancelling. What is really outstanding, however, is the sound quality. These compare very well with other high end products like Bang & Olufsen H9is (which I also own). The sound quality is very good in wireless mode but does improve when cable connected. I would be curious to try these with a portable dac to reach audiophile levels of quality.
