Beats X all colours are even cheaper, only $139. $5 cheaper than the last post which is still available at Mr. Gerry's stores (avoid :P).
These have the same W1 technology. Work great with other phones as well.
I myself haven't bought one because I really like the AKG earbuds that come with high end Samsung phones and haven't been able to match the same sound quality on bluetooth earbuds under $200.
I think beats X 2 may announce in 2 weeks
