In my experience I feel the bad points of the Motorola HS820 are -
1. Crackly sound
2. Erroneous manual - e.g button to be pressed is stated wrongly
3. Quiet audio I feel
4. The piece that suppose to be put around the ear, is too small for my ears.
5. The 'loud-speaker' is placed somewhere for the ear clove to listed to
6. Whenever I twist my head quick enough, it is enough to send the device flying into the drain
7. Walking while talking... forget about it.
Therefore I do not recommend this bluetooth headset.

I have had this little device for about 2 years now and am very satisfied with it. Simple to use. Comfy to wear and have been able to pair it with all the phones I have owned.

Really find this to be an awful piece of kit. To add insult to injury Motorola sent this to replace a HS810 which died under warranty as apparently they no longer carry the HS810. Kept as an emergency back-up, but rarely used!

An excellent piece of kit and so easy to use.

I have had no complaints as far as echos go with the Motorola HS820, found it quite clear although this is the first Bluetooth headset i've owned so nothing to compare to really.

Apart from the voice activation, which would be useful otherwise you still need to pick up the phone whilst driving to find a contact its been reliable and good value at a mere £25.

I think some people expect the quality of a top line headset that costs upto £100 and then some. Buy this headset if you want it to do the job its meant to without all the trimmings and qualities of one that costs 4 times as much.

Expect to get what you pay for and you maybe pleasantly surprised!

The Motorola HS820 bluetooth headset was great when I first bought it. I read the reviews and was sort of doubtful of the fact that they were negative, but I still bought the device. Now it is confirmed that this device is not good. The cost was admirable, but the quality of the headset is garbage, especially over a two week time period.

I have to hold the Motorola HS820 bluetooth headset in place so I can hear, which defeats the object somewhat.

I am very disappointed. It came free with my phone, but if I'd paid for it I would have taken it back.

The Motorola HS820 bluetooth headset is very difficult to sync quickly to my Sony Ericsson phone.

It is also difficult to turn off, so it is difficult to conserve battery life.

Everyone complained that they could not hear me, and I had to hold the set right against my jawbone to say anything, so I might as well just be using the phone itself.

It's not ergonomically designed, so it feels like its about to fall off all the time.

The Motorola HS820 bluetooth headset is a waste of money. I'm really annoyed because I can't find the receipt.

I have never owed a Bluetooth headset before today. I have used the Motorola HS820, and I don't know if it's because I'm a small girl, but it feels like it flaps around on my ear, and feels like it will fall off. Is this usual for headsets (maybe I need to get used to it)? Some people say I sound far away/echoey. Do I need to shout a bit to speak into these things?

I returned my Motorola HS820 bluetooth headset the same day I received it, because of the echo problem that everyone was talking about. I don't hear an echo while talking, but the other party that I am talking to hears their voice echoing. Although it doesn't bother me, it bothers the party that I am talking to. So if you are talking to your wife or your girlfriend for a very long time you wouldn't want to use this.

I use my Motorola HS820 bluetooth headset with a Motorola 815

It is a good device. No doubt. Amazing that so much is in such a small package.

Others complain they can't hear me. Maybe a boom would help?

Others complain of an echo.

I often have to hold the device to my ear canal. It does not line up on its own. Pity. Maybe it will work better for you.

The Motorola HS820 bluetooth headset does not have enough volume for highway driving. In the city you'll be OK until a bus stops next to you at a traffic light. All windows up please!!

Although I like the Motorola HS820 headset, it's not balanced on the ear and many times it feels like it's going to fall off. It is also annoying to tell if it's on or off because you have to wait for the power light to flicker on and it only happens every 10 seconds. Volume is also too low and is barely adjustable. I also had problems connecting it to my phone (a Motorola phone).

The headset does get good range and the voice quality is still quite good.

I've had a Jabra BT200 and I currently own both a HS820 and a HBH-660, so I think I have some experience to talk about Bluetooth headsets. The Motorola's best feature is its comfort. I have very sensitive ears and I could still wear it for a long time without feeling any discomfort. And the speaker fits right on the entrance of my ear canal, making the sound loud and clear. I was pleasantly surprised to see how it paired seamlessly with both my T610 and my PC. Redial and voice dial also worked just as they should.

My main concern with this device is that it remains permanently connected to the phone, and thus drains an awful lot of the headset's battery.
The absence of beeping sounds on activation/deactivation is another quirk, albeit a minor one.

In all a very good piece of equipment, lately the HBH-660 has become the companion to my phone, but I see the HS820 as a good back-up, and it still sees a lot of action with my computer.

The size and shape of the Motorola HS820 is quite possibly perfect. I guess the trend with all headsets is toward an integrated design with no noticeable microphone boom. As long as there isn't too much background noise, this isn't a problem but the HS820 tends to pick up just about everything. I've seen other manufacturers tout their noise-cancelling capabilities but Motorola doesn't even seem to try. Realistically, if it's really noisy, people wouldn't be able to hear you very well whether you were using the headset or cupping the mic end of a cell phone into your hands. And as far as comfort, I can't imagine this small being so unnoticeable when it's on your ear. Ergonomically, the 820 deserves a 9.5. I have yet to talk for 6 straight hours or really time my conversations in order to truly evaluate battery life but I use it quite a bit and I can usually go 4 days without charging it.

While fashion may not be a major concern for most users, the thing is stuck to your head after all and it wouldn't hurt if it were a little prettier. Motorola has some beautifully designed products and I don't really understand what happened here. In particular, why did the 810 look so cool (styled after the V600) and this one look like it came out five years ago? Luckily it's small and not too terribly obtrusive.

Functionality is a little weird since you really only have one button. You change the function of the do-it-all button by varying how long you hold it down for. A long hold turns it on and off and a short hold answers and ends a call. One thing I've yet to reconcile yet (and I think this may be a typo in the manual) is that a short press is supposed to both end a call and transfer it to the handset. The exact same thing is listed in the manual as doing both. I have yet to figure out how to transfer a call to the handset but I haven't had it very long and I haven't had a reason to either.

One weird quirk I've discovered is that after ending a call, you can still hear that ever-so-faint static sound in the headset that tells you it's on. So basically, you end a call, your phone clearly indicates that the call is over, but the headset still hisses a little bit like you're on hold. The only way to make it stop is to turn the headset off. It's one of those things that's not really a problem, it just makes you wonder if you're still on the call after you've hung up, especially if the handset isn't in sight. It also can't be good for longevity because I would think that as far as the battery is concerned, it would be just like having a conversation.

The LED thing is a little weird too. It goes on and off (I wouldn't call it blinking because it stays on for a full second) while you're on a call and it also blinks while the unit is on but not in a call. However, it stops blinking after it's been on for about five minutes, which I think is stupid. LED's take such a miniscule amount of power, especially if it blinks every once in a while. There should be some kind of indication that the unit is on. At this point, the only thing you can do is hold the MFB (love the acronym) for five seconds to turn it on or off. And even then, it's hard to tell if you're turning it on or off -- you have to wait a second or so afterwards to see if it's still blinking or not.

I just got a Motorola V300 for free, which doesn't have Bluetooth, and my only experience with pairing the HS820 is with this device. I had to get the DC600 Bluetooth adapter too. Seeing how easy it was with the adapter, I would imagine it must be even easier with an actual Bluetooth enabled phone. The only weird thing (and this has nothing to do with the headset) is that there was no indication on my phone that any sort of device was connected to it. All the indication that your device has successfully paired is given by different LED blinks. I didn't quite get it at first and didn't think it had worked but magically I was able to answer a call with it.

All in all, the 820 is a killer headset. My complaints are all fairly minor, my biggest being how its physical appearance. What counts is that it works great, sound is excellent, you can get pretty far away from it and have no signal degradation, and most of all, it's extremely light and comfortable. I got mine on Ebay as a package with the DC600 for just over $100 with shipping.

For a wireless headset, the Motorola HS820 has far exceeded my expectations. It finds the phone quickly (fast enough to have it off and turn it on when a call is coming through and still answer it), and the clarity and range are outstanding. I've charged it once in the last three days, although it didn't even need to be recharged. I've yet to run down the battery. My one gripe is that I don't like the BT headset mentality of using one multifunction button to turn on/off, answer/hangup, and connect. I think Moto's previous model HS810 used a boom that turned the headset on, and the button was for answering/ending calls. I'd much prefer a separte on/off switch so I don't have to sit there 5 seconds holding the button when a call is coming through while I pray it turns on fast enough to answer. Overall though, you won't be disappointed in this product.

I find the Motorola HS820 headset to be fine if not good. It does exactly what it says it should. It is a bluetooth headset, no more, no less. The range is good and I can here the people I'm calling very clearly and they can hear me. Battery life? it lasts a good two days I would not know as I charge mine every night when I'm not using it. I reccomend to anybody, with headsets, phones whatever, don't complain about batterry time, just frequently charge the thing. Overall a good headset.

My first headset shouldn't have been too exciting, just charge-wear-forget. The range is fine (or great, can penetrate a couple of my walls). Unfortunately the battery life has been over-stated by Motorola (as usual), but by far the biggest problem of the headset (and I don't think its just MY headset) is the Blue Led of Death: the device seems to be moody and "lock" in some states occasionally, can't turn on or can't turn off or can't pair and stuff; If it was some other device I'd try the reset button or would remove the battery, options that don't seem to be available. Resolution of the locked states is usually a matter of a few minutes and plugging/unplugging the charger, occasionally I had to leave it alone for half an hour. I use it with two devices, so you may have more joy if you use it with only one.

Finally, there seems to be no available Bluetooth 1.2 device to pair it with, so I can't tell you if the promised advantages of the 1.2 standard will be delivered with this one.
