Thanks for the link. If you don't mind me asking where did you order your DX50 from? iBasso themselves? I wonder how fast is the shipping if you order thru them?
There is this reseller on Amazon who has it for maybe a few bucks less than Amazon price.
I was originally planning to get an AKG headphone but with Grado rolling out their new updated headphones + I always wanted to walk outside jaming on the RS2i = I'll order this instead tomorrow.
I ordered it from Amazon (sold by emusic enterprise):
