I bought them a year ago in Hong Kong , I do not wanna describe how good the earphones are , because they are designed for real musicians and the professionals . The RRP in New Zealand is $799. I got them around $ 600 in Hong Kong. I need money for my tuition fee , so I have to sell them. Please feel free to ask me question about them.
