I have recently decided to get the Beyerdynamic DT 770 Pro's off of Amazon. They seem to fulfill my needs for a pair of headphones. However, they are said to be more of a at-home pair. But i would be using them portably at my school as well as at home. I am new to this amp thing, and not sure if i should get one with these cans since i am already going over my budget purchasing them. (Of course amazon has risen up the price since i first looked)
I was thinking about getting the 32ohm edition, since it can be powered by my iPod. But i heard there is a sound difference from the 80ohm version. Which should i get? And if the 80ohm truly is better, what is a cheap portable amp i can use?
Are there any other headphones out there similar to these beyers? If so what are they?
