Senni HD 520 II

post #1 of 7
Thread Starter 
So I was given these by a member of family, Anyone know the history and what they are known for either way? Especially if they are any good, one thing I have noticed is directly in my iPod it requires full volume to hear well even in the quiet of my apartment.

Im sensing this either was not a popular brand or nobody has used them?

The brand (Sennheiser) is very popular, but I guess it's some old model which is why there might not be a lot of information available. iPod probably hasn't got enough juice to drive such phones although it might be because of the volume cap on euro ipods if you have one.

Yah, Im sure its an early model I have not been able to stumble upon any information regarding what its comparible to if anything now, just trying to figure things out. I guessed it was underamped so the quest to find new phones/amp continues

HD520 came out in 1990
FR: 18-22,000
SPL: 94db
Impedance:600 Ohm!

This might explain the problem in driving them.

I have HD530-II so it's pretty relevant. Well... they are not my cup of tea, but as I only have these and Beyer DT880 I uae them sometimes. They have decent bass, comparable to the beyers, but someow bloated (esp. midbass). The lower bass is weaker than beyers but the mid and high (?) bass is more present. The highs are not comparable to the beyers and also the soundstage and the feeling of space and the transient responce. But I thind they are for Sennheiser fans with the muffled highs and strong bass. There is also some review about HD540-Gold - http://www4.head-fi.org/forums/showt...hlight=pageant
