The soundcloud link you sent, they al sounded the same. what are you supposed to hear?

In a general sense yes, but the figure to look for is the sensitivity rating, which is generally expressed as dB/mW. The higher this number, the less power you need to get loud.

 

Since power delivered is voltage^2/impedance, high impedance headphones need a higher voltage swing but less current to reach high power. Low impedance headphones on the other hand don't need much voltage swing from the amp but do draw a lot more current.

 

Most amps fall somewhere lazily in the middle or lean more towards higher current. A few more specialized amps (mostly OTL tube amps) will run specifically for high impedance cans.

Thanks for the detailed head up! So which can does fit my RME Babyface? I don't use an amp.

The RME Babyface has an output impedance of 30ohms... so unless you're using an external headphone amp, you're going to want a high impedance headphone and/or one with a relatively flat impedance curve. If going with Beyers, pick either the 250 or 600 ohm versions (I'd lean towards the 250 since the RME might not jave enough voltage swing for the 600 ohm versions).

 

I just noticed you're in Europe. See if you can find a Sennheiser HD25-13. It's a 600 ohm headphone but with relatively high sensitivity, has a good frequency response, and for the most part is very similar to the workhorse hd-25-1 with the exception of higher impedance.
