I bought this based on some coworkers opinions that it worked great. Well after over a year of use, it doesn't work as advertised. It doesn't cancel out any noise and people I'm talking to can't hear me that well.
The earloops are pure junk. I broke all that came with the set. Now I can't even buy replacements unless I buy direct from China. They break so easily even after I learned the proper way to put it on and take it off my ear.

I wish I could return it, but after such a long time, I don't think I can.

It seems that nobody can make a good noise cancelling bluetooth that fits my needs. I can't use the headphone type like my truck driver friends use since they are too large and in my opinion, in the way. Besides they cost two to three times more.

The hunt goes on for the ideal bluetooth. I doubt I will ever find it.

Love the distance this thing gives you with clear sound. It's uncomfortable though. I never felt like I could get the thing adjusted to fit right. I was always adjusting it. The ear loops break after just a few adjustments and you have to buy new ones- what a racket! It keeps background noise out decently, but I wish it had the comfort of a Plantronics. I went through 2 of these and I was quite disappointed. Keep shopping.

It's a great product, hands down. Best bluetooth hands-free I've had and I've had several.

I ordered a new one & received an used one. It cost me $7+ nonrefundable postage to ship back the used one. Never have a chance to use the product. Very unpleasant on-line transaction. I will not buy anything on-line in the future.

Was extremely dissappointed in the Jawbone. In short it's very poorly designed and doesn't provide the performance as advertised. It doesn't fall a little short...it's not even close to the mark of bluetooth headsets that I used several years ago. I'm a average sized man with average ears, facial structure etc. and could never get the Jawbone Headset to rest comfortably in my ear or have the earhook not create an unpleasant, uncomfortable feeling. I was always sure to have the contact point touching my face to be sure the noise cancelling worked correctly but people always told me I sounded like I was on a speaker phone and at times had real difficulty hearing me. I use this in business everyday and it conveyed a very unprofessional "appearance". I tried everything I could to get better performance but nothing worked. I used this for several months giving it every opportuniy to perform. The fit to the ear is a serious problem for a lot of people and a major disadvantage to this headset not to mention the poor sound quality.

I replace it with the Plantronics Discovery 925 Bluetooth Earpiece(better price and the latest "clear" technology), which comes in BLACK, SILVER, GOLD, and PURPLE. The fit to the ear is extremely comfortable and secure, the receiving sound excellent and to the person I'm talking to they say it sounds like I'm on a land line. Never anymore complaints from peole I'm speaking to. From another reviewer's recommendation, I also purchased a windscreen that you can use to cover the end of the headset that's exposed to block any interference with wind noise. So if you know you're going to be outside at a ball game, riding a bicycle, etc., you can slip this on and have a headset that blocks virtually any wind noise making this the perfect unit. I bought two of the windscreens and keep one in my car and the other in my latop computer case so they are ready to use when needed. You can order directly from Etymotic Research, item # ER89-30 only $1.75 per set. www.Etymotic.com The Plantronics Discovery 925 Bluetooth Earpiece also comes with a charging case that not only safely stores your headset, but serves to recharge it if you were to run the headset battery down...very cool bonus feature for long trips...and long conversations when you can't charge your headset with the hard wire! Check out the reviews on the Plantronics Discovery 925 Bluetooth Earpiece and buy instead...you'll be glad you did. By the way, I've had 6 to 7 or more headsets and the Plantronis is the best that I've had so far.

No complaints about the earpiece, I've bought several for my company. But if you break the earloop (and you will ventually), you'll have an unusable unit because the Jawbone folks have decided to discontinue the replacement item. Be warned: the earloop for the new Jawbone II WILL NOT WORK with this original unit.

I've owned Motorola, Plantronics and several other bluetooth headsets and got really tired of having three fourths of people tell me to call them back when I'm not using the bluetooth headset because they couldn't hear almost anything.
The Jawbone's worked perfectly from the start.
I've had a couple of hassles with the ear-piece, but this is finally a bluetooth headset that I can use. I'm happy as a lark

First let me state the things that would be 5 star worthy. The technology in the noise shield is nothing short of mind blowing. On a city street with buses and loud traffic or sitting in my hotel room with no noise, people I talk to can't seem to tell the difference. I also having tried many Bluetooth headsets can say I can also regardless of noise hear better on this unit than others.
Now, the less than a star what were they thinking part. It doesn't fit well and I don't care how much you fiddle with it. The way the earbud attaches sucks. Half the time while trying to get the fit right I turn it the wrong way and it falls off in my ear. The buttons make a crunch noise when you push them like the unit is breaking. When unplugging the unit from the charger it always feels like it will break even when you do it exactly like the customer service jerk tells you to (mine actually did break recently unplugging it).
And still... the technology works so well it is worth overlooking these problems and buying.

Bought 2, sound and quality of device excellent, The wire for the device that hold on ears is very poor and breaks very easily. Had to order replacement parts the first week. Would be outstanding device if the wire hold would be corrected.

One of the best at noise cancelling. Only complaint is the ear piece doesn't fit as well as some of the others and therefore you don't hear as crisply as you might like.

Otherwise though, its pretty darn good.

The theory behind this device is pretty great, however in actuality it doesn't perform the way you would like it to. When I purchased this product I was expecting something that I would be able to use in the car with the windows down, or at least the moon roof open. I think just about everybody that I spoke with while I had the windows down asked me "what that noise is."

Now I understand that the technology contained in this device is meant to cancel out 'white noise' and not necessarily wind etc., this is not the main reason I gave it two stars, the reason I gave this device two stars is because the craftsmanship of the headset is cheap. I had one of the ear loops break on me within the first week or so after buying it, luckily they provide you with different ear loops as well as ear buds. In addition, the charging cable was (in my opinion) poorly designed and as a result of plugging and unplugging the charging cable enough times the back segment of the headset has not broken off. Now I have to plug in the charging cable and then wrap the cable itself around the headset lengthwise to the back of the headset doesn't pop off while charging.

And lastly, sometimes the headset will not even turn off, which means if I have it on and go to turn it off (to conserve battery power) then it won't turn off and a day or so later the battery just runs down and finally the device shuts off. I'm sure you can imagine that having the aforementioned charging issues I REALLY don't like having to keep charging it either, so basically this $100 or so device is worthless to me.

I have an old Plantronics BT headset that works as reliable as ever which I now prefer and I got it on a well known auction site for $18 about 3-4 years ago.

So in summary, I don't feel as though the money is worth it for this headset, wait another year or so. Popular Science had a small article about true noise reduction BT headsets recently, so look for those in the near future if that is what you are looking for.

I had read all the reviews before purchasing so I was prepared for the ill fitting earpiece. BUY the Jabra ear gels WITH the headset! I cannot find them at Radio Shack as directed in reviews.
The Jawbone is great. I am very happy to finally find a bluetooth that works great after trying so many others.

After a few weeks, the back of the device broke off in the charge, exposing the circuit board and preventing from charging. I super glued it back on and covered the glue mess with black marker.

I ran into someone at work and asked him about his. Sure enough, he had the exact same problem (even used a marker to cover the glue marks).

The other day, I drop it on the ground (not an uncommon occurrence for bluetooth headsets) and the metal ear loop snap off!

This thing is a piece of junk. Even if it never broke, it's difficult to carry in a pocket due to the big ear loop. Also difficult to put on.

I'd recommend avoiding this product.

I just got the Jaw Bone for my birthday. I connect it to the charger and let it charge over night. I try to remove it from the charger and it won't budge. I read the manual and it says nothing about removing it. So I pull a little harder and the charger rips the entire back end off the head set. I still can't get the broken piece to come loose from the charger. WTF!!!

I spent many hours researching the latest and greatest of blue tooth headsets and chose this one based on perceived quality. Price was not a big issue. It is very lightweight which was great. Easy to use as well. The biggest problem was the sound level. You can hear the caller if you are in a quiet place. However, as soon as the level of noise increased in the area you are calling it becomes very difficult to hear. I think the problem is the ear piece. It does not go into the ear, but rather sits on the outside. I have a Plantronics 510 and it worked with my older phone very well. it has an earpiece that goes into the ear and you can set the volume much higher. I only switched because I was getting a lot of static in the headset with the new phone (3G technology may be the issue...I dont know). I would not recommend this headset to anyone working in a potentially noisy environement (driving with the windows open, walking outside, etc)

The Alpha Jawbone has a nice clean high tech look and the fit is comrfortable for me. The unit was easy to sync with my Sony Ericsson phane and has worked well. The noise cancellation feature works as advertised and seems to do a good job blocking out any background noise. I travel a lot and blocking out noise in the airport is important to me. Overall, I have been very pleased with the product and would reccomend it to others.

I notice alot of people compain about this product because the other people can't hear them. The fact is this produce is a sophisticated piece of electronic hard and software. Proper fit is essential for performance. The product is simply fantastic. It has 4 earbuds and 4 earloops that must be chosen carefully to provide a snug touching the face fit. The noise cancellation is what you are paying for. If you have ever been in a loud place, often the problem is that the counterparty cannot hear you while you can hear them. The device uses vibrations from your JAW and sound from your voice to isolate your voice from the other noises. If it doesn't fit well no- the other person won't be able to hear you. This is simply the best headset I have used. I would recommend it to anyone that it fits and find most of the negative reviews are from people who simply need to learn to use the product better. You are paying for something that isn't just a mic and a speaker so proper use is essential to know what you've got.

The Old Jawbone works very well. Most of the time one does not know I'm using a bluetooth device. It also works very well with my voice reconition cell phone allowing hands free operation while operating my vechicle. Its just like talking to someone in your car and you can concentrate on the driving task at hand with unrestriced vision.
On the other hand the new Jawbone fades in and out as I turn my head in various directions and requires that I hold the mic with my hand to keep it close to my check. I returned the new Jawbone and procured the old one again. This is my second one and it has the best voice quality in a moving car that I have used and I have tried about 4 others.

how could a company put so much quality in the electronics and then put mickey mouse earloops with it? Ive broke the original ones plus four more, and now they are out of stock! so it will sit, until I can find some.

I was not able to make a single call with a clear voice quality with this product.With every call the other person on the line complains that they don't hear properly or voice getting cut etc.

I am really disappointed with the product.

Read a lot of reviews on this earpiece and I must say that it does deliver. Once you get used to how to put it on quickly, you will be very impressed with it. I can roll my windows down and talk on the phone without the other person hearing the outside noise. That's impressive. The only reason I didn't give it 5 stars is, I'm personally not fond of the earloop. I have tried the earbuds and they do work.

I've been a fan of the original Jawbone for a long time. It's fantastic! After I broke mine, I tried the new Jawbone for a couple of weeks. It isn't as good. I've now purchased another original one and am happy again.

Three shortcomings of the new Jawbone: (a) battery life is too short; it died 4-5 times in two weeks; the old one has a longer battery and it died only a couple of times in well over a year; (b) the ear loop on the new one does not provide nearly the hold to the face as the old one; people were complaining because the Jawbone would fall away from my jaw and cancel my own voice; (c) the new one was not as good as maintaining a Bluetooth connection with my phone.

I highly recommend the original Jawbone - it's still the best headset that I've ever tried.

Lets face it, most bluetooth headsets arent worth a darn. its just the cell phone manufacturers trying to make an extra buck selling a piece of plastic with a speaker and mic and charging an arm and a leg because its "bluetooth". Well i have to tell you the Jawbone is the exception to the rule. You all know about the noise reduction on this headset. So i won't go into that more than to say its no lie its as good as advertised. and the incoming sound is great as well. at first i did'nt like it. it sounded a little tinny but i found that that was their voice with all the unnecessary frequencies elimated. they are much easier to understand. It kinda sounds like the incoming sound you hear when people talk on aircraft radios.
The real enjoyment for me with this headset is the design and materials. first the ear loop is metal with a rubber cover which is great cause you can bend it for a perfect fit. I guess i have weird ears cause most of the headsets ive tried just dont fit. But with the jawbone i can just bend away without taking a hair dryer to it to melt the plastic to bend it. And second most of these in ear headsets require a snug fit in the ear canal. But who among us really finds that comfortable? maybe its just me but it really burns after a while. With the jawbone as long as the ear bud is near the ear canal you can hear it just fine, and it still doesn't wiggle off your ear because of the ability to mold the ear loop to fit. so all in all i have to give it a 5, cause as bluetooth headsets go its about the best your gonna get

the company whom I purchased from was prompt and mailed missing parts immediately! Like all bluetooths its not perfect but the best I have owned!

It looks very good and the sound clarity is also good. Only one drawback what I have seen was the ear holder what they have provided are not in correct size.

cannot truly rate the product as i returned it immediately. it was not new, as presented on the description. it probably had been previously sold, returned and resold to me; there was an opened guidebook with a penciled in phone #, written on the back (they come in a sealed plastic bag). the item was returned and a replacement sent. i believe the replacement had also been previously bought, returned and sent to me. the ear loops had been opened and pulled out of their (supposed to be sealed) plastic pouch. also, the main packaging looked as if it had seen some serious action that left it scratched and marred that could not possibly have been caused by the cushioned box i recieved it in. i immediately returned this item as well. do not know what to think about this new wrinkle in amazon ordering, other than it is taking up a lot of my time ordering, re-sending and then sorting out that amazon actually needed to reimburse my credit card for the original purchase price, as the replacement had shown a $00.00 cost on the invoice (due to being a replacement) and the system initiated an email to inform me of the $00.00 they would be crediting me. a major waste of time. all that needed to be stated on the original description was "refurbished" and i would not have started the whole rig-a-marole to begin with.

Where do I start? It looks good and it works great. The price was the best I could find anywhere. Bottom line is it does what it said it would do and I'm happy with the purchase.

The product seems to function well and people on the receiving end comment on the voice clarity, but the ear pierce is not very comfortable and it feels like the device is always ready to fall out.
Must be my ears!

I would have given a 5-star for this product but due to design flaw where the charger is located. Due to this flaw, the plastic cap that covers the charger and the 2nd button broke during removal of the charger.

the new Jawbone has the sound quality you desire, especially at this price point. however, the fit of the earpiece leaves something to be desired. although there are 3 different size adjustments, the fit still is not optimal. the piece tends to fall from my ear often and needs to be placed back. unfortunately if it happens during a call the noise canceling feature stops working. with a little more refining jawbone should be a total winner.

Aliph Jawbone Noise Shield Bluetooth Headset (Black)
I'd bought several earpieces and I'd read several reviews on the New Jawbone it didn't have enough talk time or standby time I work with my phone so that's important to me. I went to several stores and there prices were exurbanite and they didn't have the older model Jawbone I'm very happy with the Jawbone I can even hear when my top is down on my carand people can hear me clearly. After much research I made the right decision. Thanxs to Amozon for having what I needed.Myra

The good news - the background noise suppression works. It is good for the people on the other end of the call. Otherwise I found the Jawbone to be a disappointment. Getting it to connect with my Palm Treo frequently takes several attempts. The earpiece is uncomfortable and awkward to put on and off.

I received my Jawbone and anxiously opened it and charged it. When it was fully charged I tried to use it. I was able to hear the other caller clearly, but they could not hear me at all. I sent it back for another. The next one would shut down by itself after a second or two.

The first two units I got were defective. I could receive but not transmit. The customer service was good. I spent a couple hours with technicians trying to work the problems but had no luck. The third unit works as advertised. It took a while but I do like the Jawbone. Reception and transmission are very clear and the noise cancellation works very well

I've had this headset for 2 months. This is the best headset I've used and is a big upgrade from my H700. The sound quality is very good on both ends. The volume on my end is loud enough that low to medium background noise doesn't drown out conversations. My wife actually says at times I sound clearer when using this headset than when I am using the handset.

Cons:
The fit could be better. This headset can be uncomfortable at times. The charger is proprietary.

All things considered, It does the job well and I am glad I upgraded.
