It was good but the earpieces aren't so good they don't go in as I would like it. So I feel like they will fall off but other wise they are okay.

The sound is good, but the ear piece came apart after a short time of use. Had to re-glue them back together. Not 100% happy with these, but they do sound better than my last pair.

I like the earpiece, but I have three minor critiques that prevent it from getting a 5-star rating.
1) it's only one earbud (as shown in the picture). i kind of like having the option to use two, to better drown out background noise.
2) i'm doubtful of its durability, especially if treated roughly. no problems so far, but the wire feels quite thin.
3) the sound quality and clarity are not the greatest. sometimes my conversations sound muffled or like they are happening "underwater."

but for the price, i think these minor drawbacks are very acceptable!

I am sorry but I wouldn't really recommend these to my friends. I  bought these in September and they were great I loved them. It's been less than 2months and the left earpiece is not working. I think it's broken from inside. It kinda feels useless with just one earpiece  working.
Very disappointing and I feel I wasted my money.

The earpieces broke off after about a week. They fell off my hat one time and both earpieces broke off

The plastic earpiece is comfortable, but the tubing is a little flimsy so it took some patience to get it secured around my ear.  Sound is nice and clear.  Microphone works well, but I haven't needed to use it in a noisy environment yet.  It might be an issue as I don't think it's a noise cancelling mic.  Overall good buy!

-friends can hear me and i can hear them perfectly fine.
-only bad thing is if you put the headset earpiece over your right ear it makes it so you have to bend the mic a lot which is frustrating.
-it's not that comfortable either. so might want to look into another headset.

I have had this earpiece for over a year. It works great; however the rubber part that goes around your ear starts to separate after a while. But it still works great.

ArriveD as promised, Sound was good, the stiff cable that attaches both earpieces did not allow the earpiece to fit comfortably, although they never fell out the cable forced the earpiece to sit in front of my ear instead of laying behind my ear. I have returned this item to amazon

I bought this earpiece a month ago to go with my brand new Nextel i870.  It worked sorta ok but was a bit finiky when used with my phone in my belt holder.  I didn't wear it all the time, just when I was commuting to and from work.  I kept it in my pocket so it would be on standby, in contact with my phone.  Most times, it would connect quickly and function well.  Ocassionally, it would seem to connect, but when I attempted an outgoing call, it would disconnect.

I also had trouble hearing the unit while driving.  As I am approaching my mid 50's, my hearing is not as acute as in past years, and the internal noise from the pickup truck (windows up, and AC running) makes hearing the other party on the earpiece difficult.

My main problem with this unit is the recharge plug.  I have 3 Nextel/Motorola phones that use this type of plug and have not had any trouble with it.  The plug end has a release button to depress when unplugging.  The catch on my HS850 charger plug was more difficult to release and required much more pressure to release than my other 2 Motorola charger plugs of the same type.  This contributed to undue stress on the socket and eventually the socket pulled loose.  I probably charged it 6-7 times over the month I had it.

I intend to replace my HS850 with some other type that has an earpiece that fits in my ear, providing some sound isolation from environmental noises, rather than the lay on this ear type.

Be careful unplugging this unit from its charging plug.

The sound quality for the earpieces is good, but they fall apart quite easily.  I have a case that came with an old set of ear buds and I keep them in it when I'm not using them in order to protect them from damage, but they still fell apart.  Also, the microphone isn't that great.  I either have to shout to be heard, or hold the mic up to my mouth, making the headset NOT hands free.  They are very inexpensive though, so at least I didn't have a lot invested in them.

The earpiece is not like the old plantronics line with the clear removable earpieces that worked without an ear hook.

This one forces you to use the ear hook and the soft part extends into your ear canal but is very large and angled funny so it really doesn't fit well. The ear hook also doesn't work well with glasses and I have to fight with it in the car, making it just about as deadly as just holding the phone to my ear.

Sounds quality is also a step down from my M100, though it may be due to the poor earpiece fit.

Good sound quality but the padding on one of the ear pieces has come off because they are not attached firmly..

I have had this product for a month.  I am using it with the Moto Razr V3.  It works well and is easy to use.  It is also fairly comfortable.

My problem is that the rubber earpiece fell apart.  It provides a cushion for your ear.  It would be easy to replace (it simply snaps on and off).  I called Motorola to order some (I figured a dozen would last me a year!)  I was told that they don't sell the earpiece separately.  Since it is in warranty the only way I can fix it is to ship it to them and they will then ship me a new one.  So, I have to go without it for about 2 weeks.  If the next earpiece lasts as long as the first one, I'll be without the headset 2 weeks out of 4 while it is being replaced!

Hello Moto!  Get a clue! sell me replacement earpieces!

I bought this gizmo after I lost my previous one, and was pretty disappointed when it came. It works great, but the ear piece really doesn't fit well in my ear. When I bought it, I didn't notice that there wasn't a spongy covering over the piece like my last one, and I'm really wishing I had looked at it more closely. It has this hard plastic covering over the earpiece that I guess is supposed to fit well in your ear, but it doesn't. Maybe I just have weird earholes

The ear phone is more confortble than it looks. Although its wire is very thin, I don't really think its going to last long... The telephone part doesn't have the Mute key. Just a Hold one, that's a shame. I got confused with the PDF from Plantronics. I'm giving 2 starts because of the price, volume capabilities and because its very small =].
