I have another question. The 7506s sound better to me through my iPod than they do through my laptop. Is this just a factor of the iPod being designed for music exclusively and the computer sound card lacking? I have a Samsung Ativ Book 8 and am running iTunes. Would an amp help these headphones through the laptop? Please excuse the lack of expertise-I'm extremely new to the audiophile world so this is all foreign to me.
The laptop soundcard is probably not good, in that case- and yes, as StoneDeaf4Ever said, an amp will help both the laptop and the iPod. For headphones in this price range, amps are typically not needed but will benefit the headphone and will sound better from both the laptop and iPod. If you're really concerned, then just get a cheap FiiO.
Hope this helped!
