This headphone usually retails for $349 USD which is completely overpriced. At $304.73 AUD I think its a good price - or more what it should be priced from the start.
30ohm impedance so doesn't need an amplifier - reviews say its got banging bass but is overpriced UNTIL now.
Alternatively, I own an earlier model of Fidelio as well as a pair of SHP9500. Personally speaking the SHP9500 is a more balanced pair and obviously 100% better value so I would recommend it for those that do listen to a wide variety of genre. You can find a trusted aussie seller on ebay selling them for ~$150 AUD which is worth the $20 premium over a Chinese seller imo.
thanks, I love my X2HR, this is step towards different direction so I will give it a shot.
