Thanks for news update. Look forward to see their appearance.
Is it 200 yuan full price? or Does customer need to pay additional top up when MSRP is revealed? Is it possible to purchase as a 4.4 mm plug?
Of course not. That's just the pre-order price and you will have to pay in full when it is ready to ship. The final price however has not been revealed yet. K's does take custom order for plug, you just need to ask them before placing order.
