If you're not listening at high volumes, the HD598 should be fine out of an ipod. I would recommend getting a small portable amp though. Still, I wouldn't go with the 5xx series for electronic and would rather stick to a closed headphone like the Senn HD25-1-ii or an Ultrasone.
I have no idea how to properly quote your reply (sorry) but thanks for your advice!
I have done some more research regarding open and closed headphones and I think I narrowed it down to these two:
- Sennheiser HD25-1 ii
- Audio Technica ATH-M50
What would be the more wise choice to get when you consider my listening habbits?
Again, I'm listening mostly to electronic music like techno, trance, dance, rap and also some drum 'n bass primarily from my iPad and iPhone @ above average volume.
I also may get a cheap portable amp.
Unfortunately I have no option to listen to them from where I live.
