 Which pair of Ultrasone cans would the most easily driven by an Ipod Touch?
 
The
 
[size=13pt]1. Ultrasone HFI-450,[/size]
 
[size=13pt]Frequency range 20-20.000 Hz[/size]
[size=13pt]Impedance 32 Ohm[/size]
[size=13pt]Sound pressure level 96 dB[/size]
 
[size=13pt]2. ULTRASONE HFI 580,      [/size]
 
[size=13pt]Frequency range 10-22.000 Hz[/size]
[size=13pt]Impedance 32 Ohm[/size]
[size=13pt]Sound pressure level 101 dB[/size]
     
Or the,
 
[size=13pt]3. Ultrasone PRO 550?[/size]
[size=13pt]Frequency range 10-22.000 Hz[/size]
[size=13pt]Impedance 64 Ohm[/size]
[size=13pt]Sound pressure level 102 dB[/size]
 
[size=13pt]I'm just looking for a powerful sounding pair of over the ear headphones with detail and powerful yet well defined bass for driving with an Ipod and no headphone amplifier. Which one or ones of these 3 Ultrasone cans would do this best? [/size]
 
[size=13pt]-Thanks[/size]
 
Also I understand that a 32 ohm impedance is better for driving an Ipod correct? How does a 64 impedance hold up?

The 32ohm Ultrasones are well driven by the better ipods, the 580s sound very good straight out of my iphone. An amp brings out their true potential but the hpo is quite listenable.
