The hunt for a decent and well priced set of bluetooth headphones for iPhone or iPod is stil on going. I took a look at the Jaybird Freedoms and found the sound woefully lacking in all areas and almost impossible to operate one handed. Plantronics Back Beat go's got less than stellar reviews but the back beat go 2 look to be a refinement in every way. These headphone have all the usual refinements such as moisture resistance for when working out and some improved sound drivers to help with bluetooth audio not sounding as good as it should
Plantronics BackBeat Go 2 Deep Sleep
By far the most interesting feature is Deep Sleep. If you walk out of range from your paired device, the BackBeat Go 2's power down but don't power off. In this "sleep" mode Plantronic claim it'll sleep for about 6 months.
My set has been ordered and as soon as they get here i'll be posting a Plantronics BackBeat Go 2 review
At the moment you can't get them in the UK but USA and Canadian customers can go directly to the product page and order away
