Sound is soso. Form factor is good. Siri and voice control integration has been removed from this speaker.  Range is ok. Price is debatable, on one hand its too high given the sound quality, on the other is good given the intended use. If your not active don't get this one you can get better sound for less, if you are as I am then this is your only option.

I like this headset but I don't love it.  After using it for a couple months, I like it's portability, comfort, and that it holds a charge for along time.  One day, I had teleconferences for 4-1/2 hours, and it worked fine the entire time.

However, every few days, the headset malfunctions and my caller can no longer hear me even though I can hear them.  I have to turn off the power, turn it back on, and then it works fine again.  (I have an iPhone 5, updated to the latest iOS, and since this is the only phone I have used this headset with, I have no idea whether or not it's a phone issue or an issue with the headset, but I suspect it's the headset because of how it works fine again after turning the headset off and then on again).  I would have rated these a 5 if it were not for this persistent and very annoying glitch that seems to kick in right in the middle of the most important phone conversation.

The design is mostly great.  It's comfortable to wear, and it stays on even when being active.  I love that the headset is flexible and durable, making it easy to stuff into a small shoulder bag or a carry-on.  Minor design downsides:  The second power switch on the left side still makes no sense to me as to what it does; and, the volume buttons on the part that comes around the front of your neck are hard to figure out by touch; and, the magnetic feature for the earbuds is very touchy and you must put the earbuds in *just* right in order for them to hold.

Also, the earbuds fit *very* securely, muffling outside sound even when there's no sound coming through the headset.  This is great for sound quality, but I find that I need to remove the earbuds when the headset is not in use due to their tight fit making it hard to hear outside sounds.  This isn't really an issue for me, but it might be for some people.

The sound quality is excellent, for either voice calls or music streaming via bluetooth from my iPhone.  I like to use these by the pool.

I love the feature that, when you turn the headset on, announces via voice through the earbuds, "Power on.  Battery high (or medium, or low).  Connected (letting you know it's connected to your device, and if you don't hear this, a good reminder that maybe you have to switch on bluetooth on your phone/device).

Also, these stay clean, I haven't had to wash or clean them even once in the couple months I've been using them.

Overall, I really like them -- except for that glitch mentioned in the first paragraph -- and would've rated these a 5 otherwise.

Despite the bluetooth lose some quality, what matters is the convenience.

Within a few days of purchasing a "used" iPhone 6, I found that the front facing mic had died.  Symptoms were Siri not able to hear you speak and speech to text dictation no longer worked.  These features would sort of work if you talked really loud into the earpiece area at top of phone by front facing camera.  After research, I found that the iPhone 6 has several mic's and the one causing the problem was in this cable assy. I was able to make phone calls and the other party could hear me just fine.  Voice memo's also worked as well as externally plugged in mic or when on bluetooth.

I just finished the replacement and very happy to find that my mic problem has been repaired.  Siri and speech to text dictation are working normally now.  I also didn't realize it by my ambient light sensor must have also been bad on the original cable as now the screen brightness changes much quicker and to proper levels as the ambient light conditions change.

The most difficult part of the replacement was removing and reassembling the two plastic frames off the old assy. to the new one for the ambient light and proximity sensors.  Make sure you note the orientation of how they were on the original cable before you remove them and apply to the new one.  The Amazon seller photo of the cable assy. shows that these are included in the new piece but they were not.  I am referring to the rectangular clear plastic frame and the much smaller black plastic frames.

The other difficult thing was to bend the cables properly to install back in the phone as the new assy. will come all nice and flat.  Again, carefully note the cable bends on the mic and proximity sensor using your old cable as a guide.  I am including a photo of the old cable for reference.  I have added a 2nd photo with those plastic frames circled in Red pencil for clarity to note proper orientation.

Although the headset is functional, Plantronics no longer supports the software for the inline control panel so the buttons do not work properly with Skype.
In the description, it clearly states:
"Answer and end Skype calls right from the headset
Inline Panel for Easy, Accessible Control
The headset also features an inline control panel, which gives you quick control over your Skype calls. A call button allows you to answer and end calls with a push*, while a microphone button lets you mute yourself just as easily. You can also adjust volume level with two conveniently placed buttons, which increase or decrease your call's volume incrementally."
If you are not interested in these features, the headset is a decent choice for a portable, lightweight headset with mic however if you are purchasing mainly to use for Skype calls, make a different choice.

I like the sound on this but trying to get it to bring up Siri was a pain, now it just doesn't, that alone will keep me from buying another. After a few weeks it stopped communicating voice to and from the iPhone, It would pair and answer the phone with a button push but never let you talk or hear. After forgetting and re-pairing it seems to work but can't be selected on the phone. The ability to hear music and prompts from apps is a great feature but I could do without Vocalist, which I don't use. I like the M100s control setup better.

[Update 9/22/2017]  No longer holds a charge, less than 12 months after purchase.  Dropping to 2 stars.

When I first tried it out, I was underwhelmed:  the sound was ok but lacked the anticipated bass.  Two things helped it reach it's full potential:  turned up the volume on the audio source (my phone), and let the drivers "break in" for a few minutes.

It's amazing how good the sound is from this little speaker!  This one's a keeper.  I've tried out almost a dozen different portable bluetooth speakers in the past 2 - 3 years, and this is by far the best -- and worth the price (between $75 - $100).

Be sure to install the free companion mobile app.  This allows you to upgrade the speaker's firmware to the latest version, which supports voice interaction with Siri and Google Now.

Dropped 1 star for a couple of minor reasons:
- No way to pause or skip music from the speaker; many other models have this.  Instead this has dedicated buttons for Bluetooth setup and for linking additional speaker(s) -- functions which are probably not used often.
- Very skimpy directions and product information.

After my dreadful V551, I was hesitant to return to Motorola. Since my Sony Ericsson S710a didn't work out, and since my wife's V3 has been solid so far, I decided to give Moto one more chance with the V3i.

First, the build quality and materials are EXCELLENT. The machined aluminum outer casing, and machined nickel keypad, provide substantial heft (this is good) and tactility. Moto could've used a little better plastic in places, but it's fine otherwise.

Second, although its resolution is lower than the S710a's, the V3i inner display's physical screen size is about the same. Meaning it's plenty large, not to mention clear, colorful, and bright. The outer display is nothing special, but it is a compromise for better battery life, so I can live with that.

Third, unlike Sony Ericsson, the new Moto's (V3i, SLVR L7, etc.) sport an industry-standard mini-USB charging/data port, and use standard memory cards. (I put a 1GB TransFlash in mine and it is amazing.) No more proprietary chargers and cables, nor goofy Sony-only "Memory Sticks."

Fourth, the Bluetooth. Motorola has come a long way to improve their implementation, and though it is not as full featured as Sony Ericsson's, it is almost unshakable in its stability. (Sony Ericsson has the reverse trend. The T616 had great Bluetooth, the S710a's was unstable. The new W600 and W900 are equally unstable.) Range is excellent, too.

Fifth, reception and call quality are both excellent. Volume could be better, but is still adequate. I have to admit, though, that the S710a was slightly better with earpiece and speakerphone audio volume and quality.

Finally, the much maligned UI. Yes, Sony Ericsson trumps everyone with their interface and Address Book; Motorola executes both of these rather clumsily, thus requiring a steep learning curve. However, two areas where Moto outshines Sony Ericsson are 1) consistent UI responsiveness and 2) broad customizability.

My only other gripe is the 50 song limit in iTunes, even with the memory card upgrade. However, I'm an iPod owner, so this doesn't concern me too much.

Now for a word of warning to Mac users. My iTunes-equipped V3i, unlocked and unbranded, came from an overseas market (phone and manual languages included UK English, Vietnamese, Bhasat, and Thai). It has full Bluetooth functionality with my Mac, including iSync. However, some V3i's don't work over Bluetooth - the Mac can't "see" any of the phone's services, thus preventing file transfers or iSync-ability without a USB connection. I can't say for sure if this is related to iTunes or not, but so far it seems the iTunes-loaded V3i's work better. Caveat emptor!

Very reasonably priced.  Clean and compact appearance.  This phone has a pretty full range of features: speaker phone, answering machine, large tilt up digital display, geriatric sized touch keys, caller ID.  The most important feature missing is backlight for the display panel (why the heck not when it is a powered phone?).  A bigger phone book memory and ability to transfer a call log number into the phone book would be useful improvements.

Quality is disappointing:  picks up a radio station when hand set volume is turned up (not a problem with the corded phone previously positioned in the same place).  Touch keys are wobbly (need to be careful to hit the middle of each oversized key) and there is a lag before the confirmation beep and number displays, so not sure if need to hit the key again and fast dialing is impossible.  Speaker sound occasionally cuts out, probably the microphone is not directional enough and so background noise is interfering (but at least you can use it while waiting to get off "hold").

I was told by customer service there were indeed ways of controlling music or podcast thru the tap function and customization with the Jabra Assist app. That is not the case and the only option available is to attempt to use Siri which is pathetically painful. I viewed this as a better design than the Era by Jawbone but it is missing these basic functions. It is good for voice calls but you would think that a device at this price range would have multiple functionality and this has missed the mark which is truly disappointing. Product will be returned..

The simplest way to describe this thing is to say, "adequate, but disappointing."

The Good: Wonderful styling, super small size, super light weight. Portable charging system. Good sound on incoming voice.
The Bad: Bad sound on outgoing voice. Limited Support for the left ear. Portable charging system.

The Jawbone ERA is the latest in the series of jawbone devices that use the company's proprietary speech isolating technology to reduce the headset's taking up ambient sound. When this works well, it does. It kills wind noise and voices that aren't yours. It makes it so you don't have to shout your head off in public places to be heard. When it doesn't work, well, it doesn't.

The technology works by putting a contact sensor against your cheekbone. There has to be a solid contact between your cheekbone and the device and that means a good, firm fit, which means it has to fit tightly in the right position. It's one of the things that makes the jawbone look the way it doesthe need for the sensor. The sensor on this thing isn't making it. More about that in a minute.

In terms of styling, this thing is a star. I've forgotten I was wearing it. I mean that, I've had to check. In terms of engineering, it's like something out of a science-fiction moviesmaller than the first two joints on my pinky finger. It makes you want to call The Enterprise.

In terms of engineering, it puts a user-replaceable voice system into that tiny package that gives you information on connection, battery status and whatnot. If you like fooling with gadgets, you're going to love the ERA, it comes with instructions for installing a utility that allows you to change the voice it uses and how the device's controls function. If you don't, you can stick with the defaults.

It claims to have four hours of talk-time when the device is fully charged and some editions of it come with a charging cradle that allows you to extend your talk time to much more than practically anyone uses. This is a dodge: if you're charging, you're not talking and the charging cradle, like the tiny ERA itself, is something you're not going to like if you're prone to losing things.

That brings us to sound.

The sound on the ERA is of two kinds and comes in two parts. Incoming sound is okay. Not great, not blow-you-out loud, but clear. Outgoing sound on it is something else. It does isolate noise but when I used Skype's test call routine, I found myself understanding why my calls to restaurants garnered me so much, "What?" and "Can you say that again?" Played back to me, my voice was clear of ambient noise but muddy and distorted.

Considering the jawbone's sensor technology, that could be a lot of things. It could be a defective unit (it seems otherwise fine), it could be my anatomythe angle between my ear and my cheekbone (can't do much about that); it could be my beard (I'm not shaving to use a bluetooth unit). Whatever it is, it's disappointing.

Speaking of disappointing, I use my left ear when I need to hear things clearly and Jawbone sends only one ear-gel for the left earone of the two sizes that don't fit. Their doing this is a statement: "if you're not average (medium-sized ears with good hearing in your right ear) you can send us ten dollars and we'll solve the problem you gave us a hundred dollars to cause." I'm not happy about that.

All in all, I like the Jawbone ERA as a concept (good for audiobooks when you need to hear what's going on around you with your other ear). I like the ideas I just wish they had executed them a little better.

Sound is great. Removable face plate is unnecessarily difficult to replace into device. Not sure I 'love' all the function buttons. My last similar device was much easier to handle.  I should have read the (very small) print - Pandora compatible - not unless you have an "i" device.  Possible a downloadable software update to make it  Android compatible is in the works?

This review is based on my experience with the Ultimate Keyboard that I was using with my Ipad Air prior to my purchase of the Ultimate Pro.

While I really liked the Ultimate Keyboard, I wanted the ability to change the orientation of the Ipad. I like to have the entire page view available while writing. The Ultimate Pro allows you to do this by making the keyboard detachable from the case. This is also nice as you can separate the keyboard and case when not writing.

The keyboard layout has changed as well, along with the key travel and feel. It's much nicer and more comfortable to type on than the previous iteration.

The only problem I've had so far has to do with connectivity. I'm not sure if some of the bluetooth issues related to IOS 8 are to blame but I've had to clear the memory and reconnect several times, each time entering a new pairing code. I never had this issue with my Ultimate Keyboard. I'll update my review if the problem gets worse or end up contacting Belkin.

Depending on whether or not you like to have your iPad plugged while working you should know that you can't if you have it configured vertically. The ipad only connects with the keyboard with the home button at the bottom. This, not surprisingly, blocks the charging port. Not a huge deal I suppose, but something to be aware of.

All in all, it's a nice upgrade to the original Ultimate keyboard. Is it worth $150? Probably not,  but it's a solid choice for an external keyboard/case.

UPDATE (12/3/2014): So, I returned the first one to Belkin due to the connectivity issues. It worked fine for a few weeks but the problems with unpairing have returned. Increasingly, I am having to clear the memory and re-pair the keyboard to get it working. This is becoming a daily exercise at this point. I'm going to give it a few more days and then contact Belkin again to see what we can do. Again, I really like the typing experience and the overall functionality of the Ultimate Pro, but the connectivity issues are dragging it down. I am therefore adjusting my review to 3 stars.

I've had this unit now for over a year, and overall I do like it. It is paired with an AT&T iPhone and works well with the iPhone's voice dialing. Press the large button, wait for the beep, then say "DIAL" followed by the name of the contact in your address book. The car speaker will acknowledge.

Example: (Press button and wait for beep.) "Dial John Doe, mobile"

T325: "Dialing John Doe, mobile."

Pros:

- The automatic on/off feature with car entry and exit works well and saves battery life
- Voice dialing (which uses the iPhone's system) works great
- User interface is mostly easy to use == has a large button that's easy to find in the dark
- Pairs easily with the phone using Bluetooth
- Gives you an audio warning if cell phone coverage is lost, even when a call is not in progress
- Small and portable, so you can take it with you on business trips or vacations and use in rental cars

Cons:

- When making or receiving a second call, it sometimes does not recognize the new call request. Turning the unit off and back on clears the problem, but that's annoying.
- Speaker volume is sometime inadequate. Adjusting the volume in the dark is not easy.
- Sometimes the speaker(s) distort at louder volumes, so if you need the volume you are hearing distorted sound

I've had a number of other Bluetooth car speakers, and overall this is the best.

One humorous note: it announces when you enter the car, i.e., a British female voice that says: "Battery level is HIGH. Connecting to (phone name)." Well, the British pronunciation for "iPhone" is with a short 'i', which sounds very strange. So I renamed the phone EYE PHONE and now it pronounces it correctly.

I like having info at a voice command but Alexa is not as "bright" as Siri.  I was most disappointed in speaker quality and have switched back to using my Jam Plus speaker for music listening.  Speaker quality is poor.
4936824
Sound quality is quite good. Design is minimal and simple to use.  I like using the phone interface over other radio interfaces and also like that I can use any app to play through the speakers.
The software (app) UI is terrible but once I setup my radio stations and sound settings once, I haven't had to go back to it. If you like to "play" with the radio stations, you might hate it.
One more 'con' is phone calls are not the best experience. I don't have a Bluetooth device, so taking calls don't run through the car speakers and I have to hit the "speaker" mode on the phone itself. (like if you set it on a table) Luckily I don't like to talk and drive so I rarely take calls.
App versatility and sound quality are great.  Oxygen Audio Apps and phone calls... Suck.
