Verce i noticed the heating issue wasnt illustrated on that chart,neither was the bluetooth reliability as i posted.
That chart is 1 independant view of some examples on the market currently,the fact of the matter is this tech is still in early stages of developement and have problems to iron out before mass manufacturing and distribution worldwide will commence.

I do think it will happen just not until a 3rd gen is made,next year sometime.

Until then i can see the gap at 7c being filled then a rise gradually back up after 2 weeks.

Thats when i'll buy in?

It has to be at around the $250 mark and become less bulky,needs frames to be secure in the ear,charge quickly,have a long battery time,have a simple charging method like the Earin,for the hearing impaired it needs to be able to have certain frequencies highlighted or adjusted to be of benefit.
