Cons: Voice quality is horrible. Everyone I talk to on the phone using this bluetooth, they know I'm on a bad quality bluetooth, and tells me they can't hear me well. I shutoff the bluetooth and use the phone normally, and voice quality is back to 100%.
Summary: I bought one because it was Plantronics and cheap for $55 NIB. Nothing but junk. Called Plantronics support. Did firmware update. Did not fix. They would not swap. I had a Plantronics Discovery 925 that had far superior audio quality. I went to a jawbone era and have been very pleased.
Summary: Talked to customer support, they sent me a new one... same issues. Called second time and they will not refund, or exchange for new product. Basically I'm stuck with a $100 unit that does not work properly. I am highly disappointed in Plantronics and will not be buying any products from them, home or office in the future. Customer service will not work with you. I have had over 10 headsets my entire life and this is the worst.
Pros: Size, weight, look and buttons... they are all great, BUT....
Cons: DOES NOT work with iPhone hardly at all. The phone is 2 feet from my head on my desk and all you hear all day is "Phone 1 connected", "Lost Connection", "Phone 1 Connected", "Lost Connection", over and over. Forget about putting it in your pocket and walking around on a call, it drops and the iPhone pics up the call where the headset dropped the connection.
