It doesn't cost 150 euros, it costs 150$ including shipping, which is ~107 euros. As for the fit, it needs some getting used to and finding the right tips. It's not the easiest iem to use, but for the money and the sound it's a good buy, unless good noise isolation and sparkly treble are your priorities.
No, Dreamthinker was right, he was talking about this: http://www.zococity.es/list/64/64/2/1/1/Auriculares.htm
149 Euros is what Radius cost in Spain. I guess it cost a lot of money to import electronics to ES so price is higher there.
Also, there is no price of 150USD in the market. (at least I am not aware of this deal); $168 at MusicaAcoustics is lowest I believe. That if you purchase from an Authorized Radius reseller.
In UK i price is 119 Pounds. that is around 135 Euros.
From now on, Japanese gear will only cost more, since the collapse of US currency. Dollar worth nothing these days.
What ever sold for 300US prior the devaluation, now rose to 350. JP yen is biting all records against Dollar. what a shame for US economy; ordinary people like us on head-fi will have to pay the difference from our own pocket....
