Actually even Koss is hard to find in Singapore too!
Yeah but I can't find it without purchasing it online as I don't live in Singapore... I'm from Brunei! South-East of Singapore right above Borneo Island! Even thought I go Singapore regularly, but hey! I only go Singapore during daytime at night, I am going back to Johore XD
I thought you can find Koss at Jaben Sg? The worse of all is, no Hifiman!
