The models are SHB6102 & SHB7102, I ran through some reviews, they are not that popular but they are both decent quality product. I read a review said the RRP here is $299 for both of them. I grabbed one each, It's definitely a bargain whether it's used for music or simply as a bluetooth headset. The amazon uk has it for around 150 AUD.
Don't think it will last very long, I did some frequent refreshes and saw they went like crazy.
Don't forget to use MBC money back on it.
buying branded with 12 months warranty, i think it is good bargain
