Thanks for the info DrSheep. I have bought my last minute in the Hong Kong airport before going to UK.
I recommend getting the AKR03, Samuel777, I only have these for a day and listened to it for about 12 hours, it is amazing and I am using an iPhone, as I'm saving up for an AK, imagine it on an AK player. I used the headphone to test in a AK240 listening to the sample songs in it and it is great. On an AK120 II, I would imagine it would still be awesome sounding.
If you can't get the AKR as it is only available in asian countries, i suppose the roxanne is the same just don't have the 2.5mm AK cable for the AK player. I've heard the seller in one of the headphone store in HK I looked at before I bought it in the airport that there is not much notable difference between the two if you are using a normal player but you have an AK player so the AKR would be better, a lot better.
