I'm using the Motorola sd-10 and I hate it
It gives me headaches that lasts days and I've had to replace it twice since I bought it in July because one of the headphones stopped outputting sound
I had a pair of plantronics 903, and I loved them (long battery, verry comfy, just work!) but when they died, the motos were on sale for 55$ and the plantronics full price at 90$. I regret it
I'd get the 903+ if I were to buy them again, the 903s range for. Bluetooth isn't great and depending where my phone / iPad is it'll drop signal rather easily.
