My brother got me the Ultimate Ears SuperFi 5vi from Amazon and shipped to Singapore via Borderlinx as Amazon do not ship certain items directly to Singapore. It cost US$64.99 (S$86) after discount, original price is US$169.99 (S$225) and Singapore RRP is S$299. My brother bought 3 and shipping charges for all 3 Ultimate Ears SuperFi 5vi is US$25.34 (S$33.55).
I kinda like the wire of the UE SuperFi 5vi as it does not get entangle easily as compared to Klipsch Image S4i. There are more earbuds included in the package (including foam ones).
Heard from my colleagues and surfing Hardware Zone forms that this quite difficult to find it in stores. So I stumbled upon Treoo and Bluetin that sells the Klipsch Image S4i. I eventually chose Treoo because it is cheaper and it doesn’t charge me extra for paying with my PayPal.
