5Slick design, lightweight, solid noise cancellation and easy listening
By Jerry Saperstein
In our era, the collection of matchbook covers from a thousand restaurants and bars has been superseded by the gaggle of abandoned and unloved Bluetooth headsets. My Plantronics Voyager 510, though, has seen a lot of Bluetooth headsets come and go in its time. For some reason, the 510 has remained my most often used BT headset, despite its very weird power adapter connector.

But the Plantronics Voyager Pro HD may be the new kid on the block and quickly become my go-to Bluetooth headset.

The Pro HD is a beautiful piece of design. It weighs practically nothing and the housing is perfectly designed to slip over and balance on your upper ear. I've worn it for several days now and, with one exception, have almost forgotten it was there. The exception is when I put on or take off my glasses - that requires some maneuvering simply because there isn't that much room between my skull and my ear. So I have to make sure everything is arranged just right.

Plantronics has winnowed down buttons and functions to arrive at an efficient and minimalist three buttons. The Power Button has three functions: 1) power on or off, 2) battery voice level alerts and 3) pairing activation. This last, after so many headsets that force me to remember arcane combinations of two buttons, is a blessing. Hold the power button down until the LED flashes red/blue and you're good to go.

The Volume/Mute Buttons also have three functions: 1) adjust volume level, 2) mute the mic (with a 1 second press of volume + and buttons) and 3) pause/play streaming audio. These buttons are generously sized and rise just a bit above the surface of the case for quick and sure operation.

Finally the Call Button allows you take or end a call, redial, initiate voice dial (if your phone supports it) and reconnect lost connections between the headset and device.

Set-up is dirt simple: hold the power button down for a couple of seconds until the LED flashes red/blue and pair I with your device. I paired it with my Lenovo laptop and Motorola Photon 4G phone in just a few seconds without hassle. The headset will support two device connection profiles.

The Voyager Pro HD is capable of A2DP so you can steam music, podcasts, GPS announcements and the like from a suitably equipped phone or other device. Remember, though, that not all phones and computers support A2DP. Mine do and the unit performed well with Pandora and other streaming audio. Volume could be higher but, frankly, if my hearing were better I probably wouldn't complaining. The headset, by the way, ships with a medium eartip installed and small and large ones in the box. I'm going to try the small eartip to see if I can get a better seal to block extraneous noise.

The microphone is supposed to be noise-cancelling and my tests to date indicate that it does a pretty good job. I tested it with a few online recording services, dictating to Audacity sound editing software and in chatting with people. The humans reported they could hear me clearly and I was, frankly, surprised by the clarity of my voice on the recordings. At some point, I will test it with Dragon Naturally Speaking to see how it works with voice recognition software.

The Voyager Pro HD has sensors and can recognize when the headset is being worn. This is pretty neat stuff. You don't have to keep the headset on your ear all the time. Leave it off and when you put it on to take a call, the headset turns on. Very neat! Likewise, if you leave the headset off and there is an incoming call, the headset will route the call to the phone.

As with many headsets, an incoming call stops audio streaming.

Battery life is excellent, in excess of four hours talk time and I don't know how long it will actually last in standby. Charging is via a standard microUSB port. Plantronics includes an AC adapter and a separate USB cable. Nice of them.

A one-year basic subscription to Dial2Do is included, under the Plantronics Vocalyst branding. Dial2Do is an interesting service allowing you to leave reminders, send and listen to emails and texts - if you pay for an upgraded subscription, post to Twitter and Facebook, connect to EverNote and a little more. It is a pricey service, so check it out thoroughly before you become too enamored of it.

Overall, this is a beautiful Bluetooth headset, not only in terms of the sleek and smooth design, but in the feature set as well. From the simple three-button operation to the excellent noise-cancelling microphone and the pretty good audio output. My favorite feature, though, is the weight and fit of the unit. I can put it on and wear it for hours without any discomfort. That, to me, is very, very cool.

2Unpleasant audio; incomplete automatic behavior
By M. Kobb
I purchased this headset from a local store, not from Amazon, because I needed it immediately. But, I read the reviews here and I had high hopes that it would be a great headset for me.

Unfortunately, while the headset has several innovative features and is comfortable and well made, two issues have caused me to return it.

I should start by saying that I used the headset with the iPhone 4S.

First, the good. The headset is comfortable and easy to put on and take off, although the large piece that goes behind the ear is difficult to put on while wearing my Oakley M-frame sunglasses (I have to move the temple on the glasses, put on the headset, then put the glasses back in place). People I called reported that the audio quality was very good. I like that the unit has real volume buttons and a real "answer" button. I like that it shows battery level on the iPhone's screen. I like that when you turn the headset on, if it's on your ear, you hear it report the expected talk time remaining via speech. Bluetooth reception was adequate.

The proximity sensor is a great idea, and some aspects worked well. I *really* liked being able to answer a call or switch to the headset just by putting it on my ear. I will miss this feature a lot! On other headsets, I've had problems where I have been speaking on the handset, and I happen to walk through a room where my Bluetooth headset is sitting. When the headset comes into range, the call switches to the headset, and mayhem ensues. This headset won't do that, because it "knows" that it's not on your ear.

Now, the issues.

First, the audio is, in my opinion, trying too hard to be "HD". It sounds to me as if there is a substantial treble boost applied, so when listening to speech (either on the phone or via A2DP on a podcast), sibilant sounds like "S" are over emphasized and actually a bit painful to have blasted right into the ear. I think the audio would also benefit from some applied dynamic range compression, particularly on phone calls. When driving, if I turn the headset up loud enough to reliably hear the other party, those sibilant sounds are excruciating. And, when the other party happens to shift their own telephone so that their voice gets a bit louder, you really get blasted. Reducing the dynamic range would be entirely appropriate for telephone audio.

Second, despite the great aspects of the proximity sensing feature, it is a bit unreliable, and also not well implemented for A2DP. I had several occasions where putting the headset down on a table caused the proximity sensors to believe that it was on my ear, and this caused paused audio from the iPhone to resume playing -- through the headset I'm not wearing. Result: lost place in my podcast. More bothersome, it continues to accept A2DP audio even when it knows that it's not on your ear. On the iPhone, this means that all iPhone audio signals like text alerts, key clicks, sound effects, etc, are sent to the headset sitting on the desktop, instead of coming out the iPhone's speakers as they should. This really completely defeats the purpose of the proximity sensor, and makes the only viable option turning the headset off completely when it's not in use (so you lose the proximity-based answering feature as well).

I hope Plantronics may address these shortcomings in the future, or perhaps another manufacturer may implement a sensing feature. I will truly miss the parts of this headset that worked well, but I can't risk damaging my hearing with the blasting treble, and I'm tired of missing text alerts on my phone because the audio is not routed properly.

5Great Lens
By hp
Bought this from a NYC camera store and was delivered to me 11/11/13. I put myself on the wait list the minute it was announced so I am likely one of the first to get this lens. I have had only a few days worth of shooting but will put my initial impressions here.

Pros:

1. Superb optics. I am not a pixel peeper but no issues at any focal length even wide open. The lens is very sharp with fair contrast. No significant distortion. Slight CA. No noticeable vignetting in real life situations. I am not sure if my EM-5 is correcting for this lens with software. I have not tried on Panasonic bodies. All of this at a constant f2.8 throughout the zoom.

2. Size. No comparison to larger format lenses with a constant 2.8 aperture in this focal range. Others manufacturers might make FF and APS-C cameras smaller and smaller but they cannot match the size of the m4/3 lenses.

3. Very useful zoom range for the average shooter. This can be the one lens you can have for the entire system. It covers semi-wide to semi-long, good for landscapes to portraits. You might want to get prime lenses for bigger aperture, smaller size or shallower DOF/subject isolation but with the newer m4/3 cameras that do well at higher ISO, this lens is fine even for night-time photography.

4. Fantastic build quality. Olympus 75mm might be a tad better made but it is close. I should know; I own most primes from Olympus and Panasonic and a few zooms. I have tried almost every lens made for the m4/3 system from any manufacturer from friends. The lens is solid with good heft but not too heavy. It has good dampened rings which are as good as any m43 lens although inferior to lenses from Leica or older (pre-digital) lenses from Nikon, Canon, Olympus, etc.

5. Looks fantastic. I know it has nothing to do with picture quality but if I was not into visually pleasing things, I would not be into photography in the first place.

6. Lens button. I love the fact I can assign DOF to this.

7. Auto focus/Snap focus. It's as fast and as quiet as any m4/3 lens used on my EM-5. The snap focus feature by pulling the focus ring back is something that gives Olympus a significant advantage over other manufacturers. Brilliant.

8. Included hood and lens pouch. I thought h*ll would freeze over before this would happen. It is getting colder recently.

9. On that topic; weather sealed.

Cons: (Minor)

1. The lens is not fully retracted at 12mm. It is actually fully retracted at 16mm. Thus, if you store with lens at 12mm, the front element is not completely against the body. I am not sure if this will impact durability over time as it is carried/stored.

2. The lens cap is huge (for Olympus). They needed to redesign the lens cap due to the hood but I feel it is too thick now.

3. The lens crashed my EM-5. The camera crashed when I first attached this lens. I am not sure if Olympus will issue a firmware update. It was interesting to find out the power lever on the EM-5 is software based; i.e., flipping it did not turn off the camera when it crashed.

4. Made in China, like iphones, ipads and most other electronics. I was hoping for Made in Japan.

Overall, a great lens and highly recommended for anyone looking for an all-around lens for the m43 system.

5This is not your average Zoom!
By NyArtboy
Honestly, what can I say about this lens that hasn't been already said? This lens has become for many reviewers and bloggers, either the Lens of the year or runner up. This lens has pro level IQ, amazingly fast AF and one of the most useful all around focal range for photography today. at 2x crop factor on m4/3 it behaves like a 24-80mm. It has nice bokeh and good DOF (Depth-of-field) at 35mm+ (70mm) and very sharp at 12mm (24mm) wide angle. Some sites have said that the 12mm f2 lens is slightly sharper but to me it's negligible. PLUS you get all this IQ and focal range in a weatherproof package! Pair that up with the OM-D EM-1 and you have an adventure waiting to happen!

Another question that pops up frequently on blog pages and review sites is the question between this and the high quality prime lenses out there for the m4/3 format. My opinion (just my 2 cents) is if you plan on shooting on nice bright days and don't want the hassle of changing lenses, then bottom line, this is your lens. On sunny/bright days you will end up stopping down the prime lenses anyway so you will get just the same amazing results especially if you pair this with an Olympus OM-D that adds in-body 5-point IS and Chromatic fixes in the software for this specific lens.

On the other hand, if you like to shoot in low light, have no problem switching lenses, and generally want the ability to achieve the maximum DOF (depth of field) you can get on the m/43 format than stick with primes. Though to be fair, the bokeh and DOF is perfectly fine for my taste on this lens at the higher focal lengths. Plus it has an amazingly short focusing distance so you can get pretty darn close to your subject which will increase the DOF as well.

If you are concerned with price, you shouldn't be. A lens of this quality at this price is an amazing deal. Here is my cost comparison/value break down:

If you bought the 12mm F2 and 45mm F1.8 you would be $200 above the cost of this lens (all brand new) and only have 2 focal lengths.
The equivalent price in primes would be the 17mm f1.8 and the 45mm f1.8 but you lose the nice wide angle 12mm focal length and gain possibly the "best portrait lens" for m4/3 cameras with nice creamy bokeh and sharp IQ.
To me the ideal prime set is the 12mm f2, 25mm f1.4 (Panasonic) and 45mm f1.8 which puts you at roughly $1800 give or take.
A nice f2.8 combo would be this lens (12-40mm f2.8 Pro) and the 60mm f2.8 macro giving you a fully capable system of varied focal lengths plus macro and medium telephoto capabilities all for about $1400.

Pros:
Extremely Sharp IQ corner to corner
Super-fast AF (I think faster then my L series lens tbh)
The best and most versatile focal lengths for everyday photography
Ability to get very close to subjects. Just a few inches in fact
Large Aperture for decent bokeh and DOF
Weather-proof!
All metal construction
MF 'choke' design for quick switching to Manual Focus mode
Includes a customizable L-FN button on lens for additional functionality.

Cons:
Big and somewhat heavy (though half the size of lets say the Canon 24-70mm f.28 L) - The size doesn't bother me in the least I have to add. Makes the E-M1 look pretty awesome.
Tube Extends during Zooming (would have liked the elements to stay within the lens, thought this would probably double the price)
Not the smoothest zoom and focus ring on the market. The other primes I have are way smoother. In fact there is small 'tap-like vibrations' when zooming. After speaking with Olympus directly they informed me this is normal operation.
Loses almost 2 stops compared to the primes available today for m4/3 format cameras.

I'm happy to answer questions posted here in Amazon. Good luck!

5Outstanding lens
By M. Gotts
I've owned Olympus' OM-D E-M5 camera body since Christmas 2012. Using the kit 12-50mm and the 40-150mm (24-100mm and 80-300mm 35mm equivalent) lenses I've had a fun year capturing photos. The camera has been everything I wanted it to be, with the exception of being just average tracking kids playing soccer.

But the 12-40mm f/2.8 lens takes the camera to a different level. I thought I was getting decent performance from the 12-50mm lens -- and I thought wrong. It's okay, for what it is, but it's slow (f/6.3 at 50mm) and just average in sharpness. With nothing to compare to, I didn't realize how it was holding back the E-M5's potential.

The 12-40 is truly top caliber. Sharp from corner to corner. Chromatic aberration cannot be found. Fast for extending the E-M5's low light capabilities at modest ISOs (I can gain nearly three stops from the 12-50mm in many situations). On the PC I'll zoom in on shots and be astonished by the crispness that simply didn't exist before.

Having never owned an expensive DSLR (I had a decent Nikon FE2 film body and some Vivitar Series I lenses in the 80's, however), I'd been lulled into thinking the images I was capturing were simply all that such a camera was capable of. The E-M5 is a very good micro four thirds body, after only the new E-M1. What difference could one lens make? Well, as it turns out, a great deal.

The 12-50mm has a smooth motor drive mode for video (which I rarely shoot) and a dedicated macro mode, which is nice. But the 12-40mm, while not being optimized for macro, turns out to be a fully capable macro lens as well, better than the 12-50, IMHO, because of its superior resolution and significantly faster performance and ability to isolate at f/2.8. The only step up for close up photography being to a dedicated macro lens. (And yes, I know that with regards to depth of field it is twice that of a full frame sensor. But f-stop is dimensionless, and with regards to light-gathering-per-sensor-size/exposure/ISO, f/2.8 is f/2.8 is f/2.8, whether it be APS, M43, full frame or a large format camera.)

The only thing I don't like is the price. $1,000 was a big chunk. But the way it has changed the performance of the E-M5 is truly revelatory. There really is a significant optical difference between a decent mainstream consumer lens and a pro level lens. The 12-40 lives on my camera now, and the 12-50 is going to end up on eBay.

If you've got the E-M5 or M1 and can afford it, this lens is a no brainer and will not dissappoint. Since the long end is only 80mm equivalent, I think even Lumix body owners can enjoy it's benefits despite not having the in-camera stabilization that Olympus bodies have.
