Best Bluetooth Headset I Have Ever Used

I have had this headset for about a month. Amazing! I love the in-your-ear ear buds, the sound quality, the ability to connect to my pc and phone at the same time. Peopke say they can't tell I am on a headset. Just love it!

Great product.  I used to use a (more expensive) Jabra Bluetooth Headset but wires between headset was a little too long where it would stick to my sweaty skin when turning my head left to right, pulling out the earbud from my ears eventually.  Trained for a marathon for months using this headset.  I was worried the battery might die before finishing so I purchased a second pair to have with me as a backup.  Used the headset all day including traveling time to the race start, during the race, Live Video streaming during the event, taking and making phone calls, and traveling home after the event.  Battery never died.  Sounds great, I've never had anyone complain about how the microphone picks up my voice.  Phone calls are crystal clear.  Wired is snugg to my head and I have full range of motion when turning my head and have never had an earpiece pop out.  Easily wraps up and is easy to slip into a pocket when not in use.  I've recommended it time and time again to friends.

Just a initial note - I never write any reviews,just don't have the time. I feel very strongly about the sound quality of this headset that I wanted to share my experience with those who are considering this product.

Over the years I used many different BT headsets by different manufacturers (cheap and expensive) with different phones and smart-phones/BBs. This is the first that has the highest sound quality I have ever used. The speaker is fine and I never had issues with it on most other BTs. However, the sound quality received by the person with whom I speak with was always not as good as if I talked using the phone alone. Just to make a comparison I tried calling my business partners directly from my phone (Motorola Droid), then from the phone with headphones plugged in, then using speakerphone and lastly with this new Bluetooth device. To my surprise every time I made a call with the Bluetooth connected each one of by colleagues stated that I sound as clear as if I was standing right next to them.

This is by far the best BT headset I used - Excellent sound quality, Very comfortable on your ear if using for extended period of time, excellent battery life and fast charging.

I have had many Bluetooth's and by far this one is the best i have used. Loud and clear and for the price beats even the more expensive ones i have used.

This small Bluetooth Headset is the best I have used.  I am on my second one since I wore the original out that I bought when it was first introduced.  It is very small when closed and is easy to use and carry with you and also link to your bluetooth phone.  Very few people know I am speaking using the set and it is not intrusive looking like many of the other gigantor head sets.  Great buy at Amazon and great headset, very discreet.

Best Bluetooth I have ever used. I am on my 3rd one in 2 years. Wish it had a homing device. I have lost the last 2.

I purchased this Bluetooth headset after my Motorola Bluetooth died after one year.  It takes a little getting used to fitting this headset to your ear, but once on it is very comfortable.  I read one comment that it is difficult to wear if you are wearing glasses but I have not found that to be the case.  The clarity of sound is good, and the controls while a little fiddly work well.  The battery life is amazing, I am still running on the first charge and I use my headset every day.  If you are looking for a good Bluetooth headset at a very reasonable price I would recommend this one.

This is an absolutely incredible headset! I've tried several Bluetooth headsets for my phone and music, and found most to be quite uncomfortable.

There may be headsets on the market with better overall audio quality, but the quality for the 855 is very good, and the other benefits such as low weight, comfort, noise suppression due to earplug design, far out weigh any marginal increase in audio quality. Price is also great! I got mine here on Amazon for less than $70.

I use mine in my Jeep and on my motorcycle, and the design blocks all external noise, giving me a nice quiet ride - even without the music playing.

I believe this is the most versatile bluetooth headset on the market, and one of the best all round values.

Well done Plantronics!!

This is by far the best bluetooth i have used in a long while. The talked time is my fav, the pairing between two phones works great for me at work. I normally use the over the ear hook and remove the rubber inter ear altogether. I have small ears and most bluetooth hurts after awhile i can take this to work 10 hours a day and forget i even have it on.

This Bose Bluetooth headset is simply outstanding.  I've bought many bluetooth headsets over the years and this is by far the highest quality.  1)  Fit and comfort is outstanding.  I can literally leave it in my ear for hours and forget it's even there.  The soft gel is "sticky" enough to keep it in place (I've never had it fall out) but also the gel cushion prevents any sore points.  2)  The incoming sound quality (what I hear) is clear and when needed I can turn up the volume sufficiently;  3)  The outgoing background noise suppression (what other people hear) is simply amazing.  I can be in a noisy environment (like a loud airport) and I'll ask the person I'm talking to if they hear any background noise and they say no - they can hear me fine and they cannot hear the airport background noise.  This is an important benefit if you want the other party to hear what you're saying.  I talk on my mobile phone as part of my job so for me quality was important and price was secondary.  Yes this Bose unit is slightly more expensive, but it's so much higher quality that it is very well worth the extra price.  This is one of those rare products that not only meets but far exceeds my expectations.  It's near magic how well it suppresses background noise around me.  Other bluetooth headsets may claim they do "background noise suppression" and some units I've tried work somewhat well, but nothing even close to how well this product works.  I'd give this product 6 stars if I could.  I've recommended this unit to several of my friends and they are all also very thrilled with it.  Strongly recommended.

I have tried every tried just about every Bluetooth headset out there and have never been truly satisfied.  i spend a lot of time on the phone in my business and this headset allows me to work very well, even in noisy situations.  It is wired plugs into my Iphone 6 plus as well as my computer -- great tool and I will be using this for a long time

This is the best headset I've used. I have small ear holes and can't use the standard headsets or earbuds because they fall out constantly. This one rests behind your ear like your grandpa's hearing aid. The speaker part gently sits in your ear. I forget it's even in. It sounds great, and it works with my personal and work phone at the same time. I wear mine with sunglasses all the time, but the kind with straight arms. Regular glasses would be a challenge. The indicator light is very hard to see, but it has voice indicators when you have it in so you can hear when it's on, off, connected etc. Doesn't come with a charger, just a USB cable but works with all my other USB chargers no problem.

May be the very BEST Bluetooth Head set I have ever purchased to date. I have had a cell phone since 1998 with a Bluetooth stuck in my ear during all call periods. Some products actually burnt the skin in my ear, some worked for a day or two then quit, some lasted quite awhile then crapped out with not "repair" function. This Bluetooth is brand new to my ear and felt great the moment I paired and started using. The pairing instructions were wrong but using a little common sense the pairing was accomplished.

Its been a while since I dabbled in bluetooth ear pieces or speakerphones. The last headset I bought was bulkier and had really poor battery life. I had given up on headsets and moved on to a Parrot BT speakerphone, which I really liked for its sound quality and battery life. But after 5-6 years of daily use, the mechanical switch broke. Leaving me with the wired headphones that came with my phone for hands-free duty. That lasted about 2 weeks before I decided to take a look at the current bluetooth hands-free offerings.

The MPow is very highly rated, so it naturally became the first one I looked into. I was concerned with how well it would stay in my ear and the sound quality. Battery life was also a concern although I figured I could charge it daily if absolutely necessary. Being fairly priced, I decided to give it a shot. I'm happy to say that it has impressed me on every level.

1. Sound quality
Everyone has one.. someone they talk to while using a hands-free device that spends half the conversation complaining about poor call quality. This person has become  my gauge for call sound quality. If he doesnt complain and I have no issues hearing him, then its a winner. The first time I spoke to The Gauge on the phone using my MPow headset, he didn't even know I was using it. He thought I was speaking directly into the phone. He was so impressed he purchased one himself.

2. Bluetooth pairing
Apparently, bluetooth technology has progressed a long way. Because this thing pairs almost instantly to my iPhone. I keep it with me, turned off. When my phone rings, I simply turn it on with the switch and within a second or so, its paired. Even my beloved Parrot used to take a few rings (maybe 4-5 seconds?) before it paired up from an off-state. I'm really impressed with how fast it pairs.

3. In ear comfort
Everyone's ears are different. But it sits in my ear well and doesnt feel like its going to fall out. I don't think mine came with that little piece that goes around your ear? If it didn't notice it in the box and I definitely don't miss it. I take it out of my pocket, push it in my ear, and flick the switch and I'm good to go. No fumbling with the piece to latch it over my ear, no worrying about it falling out. I've had hour long conversations with it and it hasn't bothered me one bit. Your mileage may vary.

4. Battery life
I've used it consecutively for one week, about an hour a day, and it hasn't died yet. I recharged it over the weekend. Not a scientific test by any means, but if it can last a week with about 4-5 hours of talk time, I'm more than happy with it. My last BT headset probably lasted like 1-2 hours at most. The MPow one has exceeded my expectations for battery life.

I've been recommending the MPow Shark to anyone that asks (and you do get a fair amount of questions from co-workers when you're walking around the office with an ear piece in your ear). If you had a bad experience with a bluetooth headset in the past, don't worry.. the Mpow Shark will definitely change your mind.

I have used MANY different bluetooth headsets.  This one was my first stereo headset, however.  Overall, this headset is amazing.  The stereo quality is quite remarkable.  Other than bass response, they are nearly as good as my Sony wired headsets, but they are WIRELESS!  I can't tell you how amazing it is to just have it lightly wrapped behind your neck.  It's a delight.  And if you just need mono, just pop off the little cable and you're good-to-go.  And the audio is still crystal clear from the single mono headset.  I am using this with the iPhone 3Gs, and all of the features work except track skip (still seeing if it's something I'm doing wrong).  When a call comes in, just slide the little boom out toward your mouth and voila, music stops and it answers the call.  Done with the call, slide it back in and the music starts right back up!  Need to pause the music, just push a little button on the top, and it pauses.  Start back up?  Just push the little button again!  Voice dial?  But of course!  Just hold the call button down about 2 seconds and your prompted with the iPhone's voice control!  Absolutely a delight to use.  LONG battery life.  I have been listening to it for HOURS on end at a pretty high volume, made quite a few calls, and it's still going strong.  I have NO complaints about the unit.  Feels great in my ears.  Very light, very comfortable.  And it's even a steal of a deal now that it's dropped so much in price.  If you're in the market for a GREAT bluetooth headset, this one should most certainly be on your short list.

I received this headset about 2 weeks ago and have been using it with my iphone 5.  I updated the firmware the day that I received the headset because of the reviews on Amazon and the warning on Plantronics website.

I gave it a 4 star because -

1.  firmware update DOES NOT work on macs,
2.  I have been hearing a hissing sound while dialing,
3.  the earpiece volume seem to be quiet
4.  earpiece sound clarity is less than the blueant headset that I also use.
(I can hear the other person fine but sometimes it is hard to hear at the end of the sentence),

What I like about this headset -

1.  Gorgeous Design:  Looks much better in person than the photos.  It is also the headset used in the Avengers per my research.
2.  Fantastic Call qualify/Noise Cancellation is fantastic:  Receiver of phone calls all said that they could hear me VERY CLEAR and they couldn't tell that I was driving.  I had this road noise problem with Blueant.
3.  Good Battery life:  I talk on the phone a lot because of work (especially while I am driving) and I haven't run out of battery as of yet.  I charge it about every 3 to 4 days.

This is definitely one of the best headsets that I have used so far.  The Voyager is SO MUCH BETTER comparing to the car bluetooth that I paid extra money for.  I kept telling my friends that doesn't matter how expensive the car is, the car bluetooh will never work well.  After I got the Voyager, they couldn't even tell I was driving when I called.  This is really what I like about it the most.

I use a bluetooth headset daily for hours for work (mainly conference calls that I speak a lot on) and ALWAYS when I'm on the phone in a car.  I am constantly on the lookout for improved headsets.

When I review a headset, there are 3 categories I consider:
 1. Sound - how well I can hear the conversation
 2. Microphone - how well the other person(s) can hear me
 3. Fit - how easy the headset it to put on and how it feels wearing it for an hour or three for long calls

My review of the Jabra SUPREME Headset:

Sound:  Fantastic.  The Jabra SUPREME does very very well in the sound category.  The sound was clear and had the best volume, without losing sound quality, of any headset I have used.  There is one annoying feature - when I turn the sound all the way up on my phone, the headset sound is not at max, I need to then use the little buttons on the headset to turn up the sound to max.

Microphone:  Not the best.  I did a number of tests between my current headset of choice,&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Plantronics-Voyager-PRO-Bluetooth-Headset/dp/B0043EV20G/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Plantronics Voyager PRO+ Bluetooth Headset</a>, and the Jabra SUPREME.  Every person I tested this with thought the Plantronics Voyager PRO+ was distinctly better.  If I started with the Jabra SUPREME, there were no complaints about the sound quality, but when I paused a moment and switched headsets (without saying what I was doing), the feedback I got was... 'wow you sound much better, what did you do?'.  Every time Plantronics came out ahead.

Fit:  Mediocre.  I really do not like the rubber covering over the ear speaker used on this headset.  I carry my headset in my pocket and the silly cover kept falling off.  Beyond that, the little loop behind the ear for the headset was surprisingly annoying and clumsy to put on when in a hurry trying to answer a call.  Also, the ear loop did not hold the headset tightly to my ear, if I bent over or leaned to far, the headset would fall off.

Other characteristics....  The headset pairs very quickly (you fold it to turn it off and unfold it to turn it on and answer a call).  The charging port has a tiny (and annoying) little plastic plug covering it, like some cameras.  I did not care about the voice recognition commands, so never used them.  The headset talks to you a fair amount with status.  If I used the headset more regularly, I'd probably turn that off.

Overall... + Great sound, -1 for microphone, -1 for fit.  The fantastic sound of the Jabra SUPREME does not outweigh the shortcomings in the microphone to me.  I could live with the fit, but I can't live with a so-so microphone.
