Hello,
 
	 
 
	I'm looking for good headphones for my new Pod Go. I'm having trouble choosing between closed, open and semi-open headphones. I also have problem with correct impedance of headphones. Do you think that 32 Ohm headphones are enough? I initially chose a few headphones:
 
	 
 
	
		Beyerdynamic DT 770 PRO 80 Ohm
	
	
		Beyerdynamic DT 990 Edition 32 Ohm
	
	
		Beyerdynamic DT 880 Edition 32 Ohm
	
	
		AKG K702
	
	
		and from a lower price range AKG K240
	
	 
 
	Do you have any recommendations?
