Bluetooth earphones suck

I’ve had the Platronics Voyager 510 for a time, used to work ok with my Motorola Razr, but it works a little less well with my Motorola ROKR E6. But I am not complaining about that here. What I am however is how horrible is its ergonomics. It is obvious, that it made for one persons ear which is not mine. The over ear piece and battery does not fit snug behind my ear, perhaps they wanted only people with batty ears to wear it, but it just does not fit right or comfortable without moving. Second where the ear piece defaults to is not in my ear but behind a lobe. Forcing it to my ear, only lasts for 2-5 seconds before it pops back behind my lobe. Its a rubber piece that does not stay where I want it, and because it will not hook to my ear canal opening, it makes hearing through the piece difficult as 80% of the sound is lost. I bought this because I thought the ones that hang a book off your ear would be too heavy and fall off. But it plain that the people that design these things are fucking morons.
