Query re "open" vs "closed"

I just bought a pair of Beyerdynamic DT880 Premium (32 ohm) headphones, the sound is good and clear but I'm suprised I have to turn up the volume control on my amp quite high to get an impact - much higher than when I use my three year old aging Audio-Technica phones.

The Beyerdynamic phones are described as "semi-closed" - I'm wondering if this has an effect on the headphone sound in comparison to a pair which are "open" ? It could also be that my ears are unsophisticated and need educating :) I would really appreciate some advice.

Have you compared the spec on your older AT headphones with the new Beyerdynamics?

I think this one comes down to efficiency! :)

Presuming when you say 'amp', that you're using a headphone amp? Because the BeyerDynamics really do enjoy being amped!

Open or closed has nothing to do with this. Open allows air into the back of the drivers and closed closes them off. Neither affect drivability.

While they're only 32 ohms, Ohms are only one part of the equation. It could simply be the Beyers are less sensitive than the ATs, and therefore need more power to deliver the same volume.
