I had the latest headset from Moto with the mike boom and loved it. But for now reason the mike quit working. But for a year it was a blessing this 4th generation HS850 worked perfect. THIS one I bought because of the price $30 and figured it would suffice. It has a better fit and audio but it's temperamental and having to turn it on and off is clumsy. I'm using a Moto V330 cell. I gave it 3 stars because not having wires is such a relief and it fits so well.
