~ DX Double W belt Korean VS Japan Version

Recently, I was lucky to bump into a review between the difference of Japan and Korean version for the Double belt. Last time, I heard collectors mentioned about it but the video review sounds was not clear. I found a link through a eBay seller about the reviews done by a Korean guy. The main difference that I notice are as the following:

1. Sounds (pronunciation difference) - Korean follows the English pronunciation and has echo effects. For example, Fang memory; Japan said Fangu while Korean said Fang. Joker memory; Japan said Jokarrr while Korean said Joker.
2. Casing color - Looks more transparent on the Korean version
3. Stickers - Japan version sticker is more shinny while Korean version has darker color.
