First, I had a Jabra, then a Jawbone - neither of those worked properly and the Jawbone just wouldn't stay on my ear no matter how hard I tried! So, I get the BlueAnt X3 micro - first impressions: nice style, lightweight, easy to pair to phone, fits well and doesn't fall off of my ear. Callers report that I sound just like I am talking through the handset and they can't tell I am using a bluetooth headset. Even my voice recognition feature on my phone works better when I use the headset versus not using it - so an A+ for sound quality, comfort and fit!Then I find out it has a slight problem. I have the Samsung Gleam as my cell phone. When a call is coming into the phone the headset rings and I push the button on the X3 to connect to the call. The call connects, but I can't hear the caller. The caller can hear me and themselves in a weird echo. If I pick up the handset I can continue with the call but not through the headset. If I place the call using the x3 everything works as it should. I finally found a way around this "bug" - when a call comes in I have to flip open the phone and answer the call by pushing the "send" button. Then the call is connected to the x3 and the conversation can go on as normal.I contacted BlueAnt customer service after trying all the troubleshooting in the manual. They had no answer for me, other than to get a different phone! Not sure about their customer service - but I guess I can deal with this minor inconvenience for now. Would be nice if everything worked perfectly though!
