Super Qualität aber wo ist die Lautstärkeu

Ich bin mit den Kopfhörern sehr zufrieden. Vorher habe ich 35€ Kopfhörer von einer no name Firma benutzt und wollte nun die Qualität aufstocken. Die Soundqualität ist sehr schön und der Equalizer auch nicht von schlechten Eltern. Der einzige Mangel ist die Lautstärke für mich. Ich hätte ein bisschen mehr wumms für 200€ Kopfhörer erwartet aber man kann ja nicht alles bekommen. Kann die Kopfhörer bestens weiterempfehlen


It was my first time buying Seinnheiser headphones, and these were at 90$ at the time, so such a steal and deal!
The headphones sound very good, the noise cancellation is meh, but thats not the main feature.
The sound, clarity, bass and everything is good... when eq'd.
Out of the Box the headphones sound very flat, plain, but that doesn't mean the drivers are bad.
You must EQ it to use it to it's full potentional, and take the Sound Personalised option too, since it greatly helps setting up the headphones.
Overall 9/10, very good Seinnheiser!
