when I turn it on, it says I have 6 hrs talk time, but when I try to use it, the voice either say (I didn't catch that) or else there is no response at all. If I use my cell phone to make the call. I can talk on my ear piece just fine. Just cannot make the call with ear piece.

Podcasts and music worked fine, but when I answered a call, I could barely hear the caller (yes, my volume was all the way up).

I will be getting a different one.

The earpiece is a good product. I tried to use it on a motorcycle as a bluetooth connection to Google maps. I wish it had more volume. It was very hard to hear on its highest setting. I'm still trying to make it fit tighter into my ear by a combination of adjusting the loop around the ear and a different size of the ear bud for a tighter fit.

I wanted to use primary for hands free answering phone, I could hear well but the other party cannot hear at all.  The mic is not walking.

People seem to have a hard time being able to hear me on a phone call, but other than that it's great.

People were unable to hear me on the other end. It was difficult to hear people talking as well, unless you are holding it just right.

Little hard to hear on it. Almost like i can't get it in my ear good enough. But, i do like it

although the phone's body was in a good condition, I can not hear or be heard during a call

i like the way it fits into my ear and the talk time. but it goes in and out of connection status even when my phone is less than a foot away. it does a decent job of blocking out background noise. also, i'm not able to answer call waiting with the talk button on the bluetooth. I have to always press the button on my phone to answer call waiting. It would have been nice if that was a feature.

The case was nice- my only coment is when making calls, the other party was unable to hear me clearly.

Albeit I'm not real crazy about the full head gear, the comfort and convince of not having something wedged in my ear canal more than makes up for it. Unless i"m around something really loud, whom ever I'm talking to only hears me. If I'm around something that loud, I can't hear what the person on the other end is saying anyway.
My only complaint, if I happen to walk out of range of one of my two phones, it some times won't re-pair.

Bluetooth works great and I like the controls on the unit, but no one can hear me unless I yell at the top of my lungs during a phone call.

This headset didn't work for me. I was on a call with it and after a couple of minutes, my call disconnected. It did it the second time I called back. I wondered if it was my phone. So I disconnected the headset and used the phone. The call was fine. I tried the headset another time just to see... It disconnected my call. So I know it was the headset and not my cell phone or the other person. It's a shame too because otherwise I liked it. I have since moved on to another headset that works great.

Callers can't hear me very well (I can always hear the other side just fine).  I tried it on 3 different phones (android and blackberry).  Same problem.  It does work sometimes.  Planetronics graciously replaced my original one, but the issue persists.  Updating the firmware did nothing.

I had this earpiece before and it worked great until it was lost.  I purchased the exact one from the same seller and it constantly drops calls, cannot hear the person I'm speaking with or they cannot hear me.  I'm not sure what the change was but it is performing terribly and I wish I purchased another model.

The volume/mute piece that came with it does not work. I cannot hear with that on and it screams when you try to turn the volume for the headset or the volume for the phone. That piece was junk, but the headphones work wonderful. Without that piece, people can hear me when they could not hear me with the volume piece connected.

I have bought many cell phone earpieces.  The only ones I have been able to hear well with were the corded ones.  But the cords are always in the way and getting snagged.  So, I have bought all sorts of bluetooth earpieces to avoid using a cord.  The Motorola HK201 is the first one that has worked well.  I was initially skeptical because of the low price, but I thought "what the heck" and bought one.  Since the most important thing for me is to be able to hear well, I am very pleased with it.  The earpiece is small and the buttons are small too; but I have managed to use it just fine.
