Korean ooo and birth drivers are now on ebay
 

While searching ebay I found the Kamen Rider OOO dx OOO driver and Birth driver.
I do not know whether the sounds are different or not as I haven't been able to find any youtube videos. Does anyone know if the sounds are different?

In one of the ebay listings, they link to a video that demos the sounds. They are very different. The only one similar is PuToTyra. All the others retain the jingle for the most part, but the names of the animals are in Korean.

Being more familiar with the way Korean sounds(thanks to kpop) I think the sounds are kinda hilarious in comparison. I want to see episodes of the Korean dub.

If you REALLY want an OOO driver, then the Korean version is probably okay. If you're wanting accurate sounds, then you're better off finding an original one. If I had the money, I'd probably buy one. If anything, for the box. Awesome packaging.
