Improper design, disables internal speaker
590566
Works only partially.  Installation is quick and simple, BUT IT SHUTS OFF INTERNAL SPEAKER.  Tried re-installing, verifying connections - no use.  The problem appears to be in electronics, not spring phone jack.  The USB port works, attempts to play any sound (no phones) emits brief sound through speaker (1-2s) and then mutes.  Plugging in phones shows sound still playing, removing phones - silence.  Put original assembly in (with broken USB) - speaker sound restored.
Thank you Amazon for the smooth return policy!

Do not buy these.  The LEFT speaker contains the curcuit board and controls for both speakers.  After a year or so of use, you'll notice te LEFT speaker will be barely audible.  Take it apart and you'll see fried components near the power supply and lots of discolored (heated) plastic.  It is a flaw in the design.  You won't get any satisfaction with M-Audio or Avid or whoever owns the company since they have exceptionally poor customer access and service (difficult website and endless loop phone circuits).  If you are inclined to simply replace the parts you won't find a wiring diagram available.  Another option would be to stack the left speaker on top of the right and have #30 of right channel for your mono listening pleasure.  I'd avoid this company's products until they get their act together.

The sound quality is fine, but two major flaws have us considering whether to return it.

1) We have connected two Kindle Fires and two Android smartphones pretty effortlessly to the soundbar.  This may not be the soundbar's fault, but it is a different story when trying to connect laptops.  Two laptops (one running Windows 7 and the other running Windows 8) were able to detect the soundbar and connect to it but were unable to install a driver to use it.  Disappointing, but probably Microsoft's fault?  (We could not find a driver on Coby's web site)

More importantly:

2) There is a weird flaw in the audio processing done by the soundbar when listening to most of the Audible audiobooks that my wife has on her Kindle.  The sound drops out on first word or two of every sentence (for about a quarter to half a second).  No sound from the main speakers, but it sounds like the subwoofer is picking up the dialog at a very low level, and then the main speakers kick back in.  (This does not happen with the built in speakers on the Kindle, on a regular pair of computer speakers, or on our other Phillips soundbar.)  We noticed the same effect on a movie where there was dialog with no background music/noise.  The input used (aux/bluetooth/line in) didn't matter.  Our best guess is that this is triggered by a moment of silence before dialog. (On the one audiobook that played fine, there is audible breathing by the reader between sentences.)  On the audiobook and movie where the flaw appeared, there was no audible sound in between sentences.

For music playback it is fine, and I may just end up trying the Phillips Bluetooth soundbar and relocating the Coby soundbar to another part of the house where we would use it just for music, but one of the big reasons we got the bluetooth soundbar was for audiobook playback, and this flaw is just too distracting.

Good design and decent sound for the price. However, 2 things irritate me about this:
1. It makes an annoying and loud sound everytime it turns on and everytime it goes off after a standby time. When I'm trying to sleep to some music, this sound wakes me up again. This is why I stopped using it for this purpose).
2. There's no button bring it from a standby or off mode. You have to fumble with the back switch and turn it off and on again to turn on the speaker again. This is a bit annoying. The back on-off switch is a bit too stiff for my liking.

The speaker without microphone on the cable is much louder, very unpleasant when calling or listening to music. But still possible to use.

Speakers provide wonderful sound; however, they require high maintenance to keep them connected to the controller.  At first that may have been because of a weak wireless signal from the source but now, I have boosted the signal to 5 bars and even after assistance from tech support, I open the controller and once again the speakers cannot be recognized by the software and I am being asked to reboot the source. A lot of pain for a recreational system.  My neighbor has same system and reports same problem.  I use a windows based laptop as a controller.  My neighbor uses an android based smartphone as the controller.

I wanted some noise cancelling earbuds and, based on the reviews, I picked these.

The good news, is they work great.  Unfortunately it is marred by one very bad design problem.

I get it, that powered noise cancelling headphones are going to need a power source (i.e. a battery), but putting the battery right in the middle of the cable is outrageously annoying.  I guess they figure you are just going to 'clip it' onto your shirt.  Which does work fine, if that's your configuration.

But, anything other than that and having this stupid battery dongle hanging right in the middle of the cord is exasperating.

I would much preferred that the power bulge be as close to the headphone jack as possible, leaving the rest of the cable completely free-flowing.

That's just my opinion at least.

i am unable to use the headphone jack on my phone without removing this case. this is a serious design flaw

I've never written a review but I wanted everyone to know about my disappointment in the soundbar connection. Here's the net of it: for some reason, there is no function on this model to turn off the TV's internal speakers. Consequently, should you like to use TV or Cable remote to control the volume on the soundbar you are also controlling the volume on the TV. No big deal right, just mute the TV, only problem there is you see a little red mute icon appear on all your programs in the lower left corner. If soundbars were a new thing, I get it, but this is just a plain oversight by Panasonic. I wish they'd develop a software fix given that the TV connects via WiFi to the internet. Outside of the soundbar, TV is beautiful, relatively lightweight given that it has a glass front and it was easy to set up.

The headphone jack is honestly pointless and I would've preferred to not have it all. I ended up cutting off the headphone adapter on the inside because it just kept getting in the way. Be careful when you close it as there may be a small gap on the ends.

The design needs work.  There way it turns on / off is poor and allows for error.  Sound quality is great.

I really want to like this soundbase. It checks everything that I'm looking for from a compact audio system. However, the fact that I cannot turn off the surround is a major issue. The audio sounds amazing when playing movies. Many times I thought I had speakers behind my couch. AccuVoice is good for dialogue and Audio leveling feature works fine if not a little muffling.

What makes this soundbase unbearable is strictly when playing music. All I can hear is audio but not the vocal. Tried adjusting it on numerous settings to no avail. Tested from different sources via optical, coaxial, and 3.5mm cable. Some sounds sound fine while others do not.

I don't like that it works very poorly with aux connection. It connects it okay, but after certain time, it shuts off the sound if the volume is not super loud. Often I want the sound volume very soft for background music or I don't need a very loud sound, but it shuts off the sound with out turning off the power. So I have to turn it on again by pressing power button. Today, for instance, I had to do that more than 10 times. This is so annoying.

The product instruction says I am supposed to keep the main volume for 90%. What I find is that I have to keep all the volume very large (90%) and adjust the volume from this speaker unit, but that's a bit inconvenient.

For instance, I have the volume of Roku, and since I am connecting my PC to it, I have a main volume of PC, and then the app in the PC has its own volume. For example, if I am watching something on Netflix, Netflix's movie player has its own volume adjustment, so while I am watching something from Netflix, I have four different volume sets: Roku, main PC, Netflix's volume, and SoundLink speaker's volume. And depending on which one I used to reduce the volume, the sound from speaker will shut off.

This is so annoying that I stopped using this speaker on my system.

I can still use this speaker for other things, like I am outside doing stuff and listen to music or something.

I feel that if the AUX has problems, they should not have put that AUX hole in the product.  I think they programmed the product to shut off the sound to save power or something (I honestly don't know why), and I think it a stupid feature, disabling the product as speaker.

I contacted Bose for this problem, and they instructed me to keep the charging cable inserted into the unit while I am using AUX. If the unit is connected to the power charge, there is a different problem. It causes a very loud static noise! And I don't know at which moment the bad static noise begins. Sometimes the static noise doesn't happen for days, but suddenly it begins. I just don't know how to prevent it except that I need to unplug the charging cable. But if the charging cable is not connected, the unit shuts off all the sound. It's just terrible.

To me, this speaker is just too complicated to use. I will not be using this for AUX again.

It could be interfered by my bluetooth devices.

First of all there is a design flaw in the grill system where shipped grills doesnot fit to the speakers -:( After multiple phone calls and mail exchanges, support guy told me to cut the edge of grill. And, I am still holding them as I donot want to go with the assle of returns.

Second, they sell in pairs of speakers, so 5.1 or 7.1 channel audio system, you will endup buying one extra speaker.

I have not installed them yet  and not sure about actual functionality of these speakers.

I received these speakers few days ago. When I plugged them into my computer, drive automatically installed, and it was ready to be used! So then I played random music I have on my computer.

BAM! BOOM! POW! WOOWOAAHHH~~...!

It was that loud. Lowest possible volume is too loud! There's some setting for adjusting volume level and stuff, but they are kinda useless for solving this problem! Sound quality is good enough, but I dislike the way the sound comes out really loud. If there's any way to get the lower volume driver or such, then it will be perfect for anyone.

When you are ready to use these speakers, install the driver and start the volume with 0%. Or else, you'll end up like what I experienced.

UPDATE: Upcoming Windows 8 fixed that sound crisis. You still can make it loud, but the volume 0-6% stays mute. It's great the problem was solved-- but only by upgrading the system.

The speakers are not set as an independent unit. The system has no ability to balance or adjust. If you want one volume and no adjustment this is the product for you.
