Thanks for your replys
I have looked up for those models and I got my eye on V-moda M100 akg k545 and NAD VISO HP50
The thing is that I'm living in Latvia and I only can buy V-Moda M100, from ebay, other sellers don't post worldwide.
The other thing is that those V-Moda seller sales from HongKong, and they are 200 £, when other sellers sell them for 350 £, how is real?
Those 3 pairs of headphones will work fine without any loss on iphone without amp/dac ?
And could you guys suggest me legit online shops, where I can buy these headphones for reasonable price ?
Thank you alot, your help is much appreciated
