Great sound. Wish max volume was a bit louder but still gave it 5 stars because it sounds so much cleaner than iMac internal speakers. Primary reason for purchase, as we love to rock out to you tube videos. Docking station is nice touch, no need to worry about connecting to charge, just set on the dock and you're good to go. Great product.

Awesome speakers.  Sound quality at high volume is outstanding.  Sound volume at the highest setting is very loud, something I've had a problem with on similarly priced speakers.

Awesome sound for the size and price. For more sound and bass, upgrade to it's bigger brother, UE Boom. Got to test it out and it sounds amazing! May consider purchasing another mini boom and pair it with the existing one to achieve that 360 degrees sound. Otherwise, amazing sound quality compared to maxing the volume on your cell phone.

These speakers sound fantastic.  So why only 4 stars and not 5.  Because I'm being exceptionally picky. I'd give them 4.5 if there were an option.  I got these speakers for my computer.  A bit of a splurge to put it modestly. They may be the best USB speakers money can buy.  It works great on a Mac with OS X 10.10. Only caveat is after you turn them on, you have to wait may be a minute before you'll see them pop up in System Preferences->Sound (because it's likely waiting to hook up for wireless play).

I got them primarily for USB connection/playing, but I liked the white cabinet and that is only available with the wireless model.

They are up against my wall by the desk and offer great bass, and the bass is really tight, not sloppy.  Could they use a sub, no, not for desk use. Could they use a sub if you use them for your general sound?  From against the wall, no.  Perhaps if you have them stand free, maybe.  Could they use bass if you were to use them for your TV/movies.  Probably, if you like that deep seat rumble, then yes, you'd want a sub, and these likely are a bad choice for that.  And I like bass, but theses are pretty great as is.

Wireless setup is decently easy.  Download and app.  Join the speakers WiFi network, give it login credentials for your network, and after that, with an iPhone, it will show up on all devices that support airplay.  Pretty simple.  Pretty sweet.

So here are my 2 quibbles. (1) My router is about 55 ft away with a wall or 2 obstructing the speakers, and streaming will have gaps/lapses at times.  I suspect if it were a little closer, it would work without gaps in play, or disconnections that I experience from time to time.  That said, I wish it were a bit more robust.  I suspect if I put a repeater or relocate the router closer, all connectivity issues will go away. (2) When you airplay/stream wirelessly, it totally disengages and stops playing anything from the computer/USB connection. When you stop/disconnect from airplay, USB audio re-engages and starts playing again.  I guess I would have liked the option that the audio from the USB and streaming mix together so I can hear what's going on the computer.  This may be a bug or a feature depending on your preferences.

The sound on these speakers is very accurate and full.  It's just satisfying to hear.  There's no 'but' with them.  I love etymotic in ear headphones, BUT they're not great with bass.  A lot of products have a 'but' and these just don't.  The sound is super clear, accurate and punchy in the high mid and low range.

When I bought these I was afraid with their high price, that I would regret having spent so much.  The only thing I regret is not having gotten them sooner.  Fantastic product.

UPDATE:  1/31/2015.  The speakers just keep rocking.  Please note is is CRITICAL that you run "Audio MIDI Setup" as suggested by one of the other reviewers, EVEN IF YOU DONT ADD A SUB.  I still don't think you need the subwoofer, but, run the Audio MIDI Setup and for the KEF X300A Speaker entry, change the FORMAT popups to be 96,000.0 Hz and 2ch-24bit Integer (It defaults to 44khz and 16bit).  You will instantly hear the sound get significantly more full even if your source sound isn't that great. I think when you change this in Mac OS X, you prevent the KEFF speakers from having to do a conversion of a conversion, and you're getting pure digital out of the mac for the KEFFs.  But it's NIGHT and DAY difference in quality.  I suspect those that wish there was more BASS heft will like the difference.

I like these headset very much. I only wish the volume could go higher. What I've found is unless you're actually wired into the music device you'll never get the intense volume one might be looking for. Short of the volume these are agreat. Very comfortable and compact for traveling.

This speaker sounds great. I wanted something that was a little bigger, louder and better without spending too much. Nyne delivers good and loud music with solid bass. I do have 2 concerns. First, there is slight ground/line noise from my audio chromecast dongle. I power it from the usb port on the NYNE and feed it in through the aux input. The line noise is only audible between songs. Blutooth is very clean with no interference. The second thing that concerns me is that some of the reviews stated that it works great then suddenly goes dead... I am hoping that mine lasts 5-10 years.

Great sound! The volume adjustment is a little annoying (you have to hold it down instead of just clicking), but the performance outweighs that minor flaw.

The sound is great! I just expected the volume to be a bit louder to fill up our room/landing area.

Really like these and the sound quality is great and everyone says the mic picks up my voice great... but I can't get them loud enough and when you're in a place with a lot of ambient noise, you want to be able to crank the volume.  No dice.  Otherwise, perfect.

Decent! Its probably not the best speaker. I wanted a Bluetooth speaker to hang over my bed. At low volumes the sound is awesome and there is almost too much bass. I listen to music and audiobooks before sleeping. Couldn't be happier with my choice right now. Just had to turn off thauto off so I can use an alarm app through it.

Sounds amazing. Love watching movies on it like being in a theater. The only con is the sound level is not that loud so when I watch a movie  I have the volume up to 100 and its fine but sometimes if watching tv it can be a bit to quite. But a great sound, easy to put together. Very happy with it.

I have had these for about 3 months now. they sound great. would give 5 stars but the housing of the ear bud tend to be a little on the large size for my ears.

Great sound and almost noise cancelling which is great for an in ear headset. However I can't get over the lack of volume control.

Great sound out of this little speaker. Battery life is fantastic. The only issue is that I find the range is a bit less than the 66 ft advertised. This is especially true if your phone is in your pocket. Minor complaint for an otherwise excellent speaker.

I just got this system yesterday, but I feel that I have tested it enough to give a fair review.  The setup was relatively straightforward;  plan on about an hour total including hookups and figuring out all the controls using the decent manual.  Once you figure out the optimum configurations for the CD player/Ipod, and those for movies, the sound is incredible for the price.  The volume has to be kept somewhat high for decent volume, but this may just be because the provided wires are too thin.  But, once it's turned up, the sound quality doesn't diminish at all, and the volume max is more than adequate.  Don't plan to use this to fill a giant hall with dance music, though.  The best part of the system, I think is the subwoofer.  That thing is really powerful;  I am kind of scared to turn it up more than halfway.  Great buy!

sounds really great with a nice bass. just wish it was louder to hear while driving on the highway since my radio is out.
