Harman Kardon Onyx Studio 4 is rated 4.1 out of 5 by 127.
Rated 5 out of 5 by from Best bluetooth speaker in its class This speaker had destroyed all other speaker in its price range at 445 dollars. It even beats some of the speakers that are more expensive. The OS 4 sometimes even go as cheap as 150 dollars. If sound quality is on the top of your list and portability and extra features aren't so important to you, this is the speaker you want to get.

Rated 5 out of 5 by from If they could correct battery/charging issues... These would be best in class, period! One "solution" I found for the battery endurance issue was to buy a 20,000 mAh power bank that is capable of 19v output. The one I bought comes with several different size adapters that will plug into the OS4. Power conversion will eat a fair amount of power (unavoidable for ANY power bank), but what is left allows me to run the speaker at full volume for no less than 5 hours! It is as if the speaker were plugged into the wall electrical outlet.

Rated 5 out of 5 by from Superb! Update! After 8 months of having a pair of Onix 4's I am even more delighted than I was when I bought first one! If you plan to buy a home hi-fi without breaking a bank, my advice is to buy these. Position them as far away from the wall (to reduce not so controlled bass), remove the grills (to gain 1db in hf range), use app to pair them in stereo mode (for soundstage), tilt them (like studio monitors for imaging) and keep those tweeters at ear level (for detailed sound)... You won't believe what sound quality these bt speakers can produce. Now at 360 USD for a pair (in Europe), I can't find anything even close... Pure madness!

Rated 5 out of 5 by from Tremendous sound!!! The best sound quality from all bluetooth portable speakers that I ever heard. The battery is too small for this speaker.

Hi I am planing to purchase 2 of them, put them on pair mode and listen to my laptop. Is it possible witouth HK mobile app? Can i listen thru 3.5mm jack? If yes, i will use only one jack for both speakers?

Asked by: Ggg7
The pairing mode of 2 Harman Kardon Onyx Studio 4 is only possible through the HK Mobile app if you mean to do it wirelessly. But you can connect a 3.5mm splitter cable to your laptop and connect the speakers with audio cables on each end to get them to play together. You would, however, only be able to get a mono-stereo sound this way.

Can I stream music from padora on my iPad to this speaker?

Asked by: Maggie
Yes, you can. There should be no problem streaming music from Pandora or any music app from your phone thru the Harman Kardon Onyx Studio 4, as long it's connected to the speaker via Bluetooth.

Can I use this speaker as a surround sound for my television? 

Asked by: CHRIS8455
We would suggest using a true home theater system with surround sound since these speakers can only do Stereo and not a complete surround sound system.

My friend has an HK Onyx Studio 3 and I have an HK Onyx Studio 4. Is there a way for us to link our speakers so they play music from the same device?

Asked by: eunit
Hi! Unfortunately, the Onyx Studio 4 uses Connect+ feature while the Onyx Studio 3 has the dual wireless sound feature. You cannot connect the two speakers because they use a different software in connecting speakers.

My HK is not paring with a bluetooth capable Pioneer Mini CD stereo system.  What am I doing wrong?

Please make sure that the CD stereo system is capable of connecting to a Bluetooth speaker, If it is, please put the Onyx Studio 4 into pairing mode by pressing and holding the bluetooth button for 3-5 seconds.Then go to the bluetooth devices of your CD stereo system and connect to the Onyx studio 4.

Even after fully charging, it shuts off after only 1.5-2 hours of play at a reasonably loud volume - the power button flashes red. If I turn it off 10-20 mins, then turn it back on, it works again. Is mine defective? Can you tell me what it might be?

Are the legs on the Onyx Studio 4 removable or not?? I noticed a response from Mark in customer service to Annoyedite stated yes, while a response from Aj in customer service to measy11 stated no. Which is the actual case concerning this?

Asked by: MG1234
Simply put, It's only removable by our authorized service centers. It can't be easily removed and requires an authorized technician to do it.
