Motorola S9 Specs ?

[Katjo8]

Hello:

I have decided that I want to buy a pair of S9 headphones. As I am shopping online for these, I see quite a bit of variation in price. the lowest I've found is $29.99. My question is this:

Does the S9 only come in Bluetooth 2.0? Or is there a Bluetooth 1.2 version of the S9 out there too? Is an S9 an S9 or do you have to make sure of what you're getting?

I want to make sure I know what I'm getting if I opt for one of the cheaper S9s out there.

Thanks for any help!
