Onyx Studio 3 is rated 4.5 out of 5 by 113.
Rated 5 out of 5 by from AMAZING sound A coworker has an onyx 2 and I have always been impressed by the volume and sound quality. When given the opportunity to WIN an onyx 3 by Sprint, I dropped my business card and suprisingly was a winner. I have LOVED my Onyx3. It has amazing bass and mid range. Volume isn't an issue when I'm working in the garage and an air compressor kicks on. My Bose was always drowned out, but the Onyx 3 I can hear clearly over the noise.

Rated 5 out of 5 by from Fantastic sound, durable I bought two of these on sale about a year ago and am totally satisfied. They work as well now as the day I bought them and I haven't noticed any difference in the battery (treat your batteries well, people!). I keep one at home and I take one to work (Work in a kitchen). Even in the hot, humid, greasy environment I keep one in, it's still working perfectly, though it's starting to look a little ugly. They say a 5 hour battery time, but I've found in reality it comes out closer to 3.5 - 4 hours. Still very nice considering the great quality and high volume they can put out. If you're looking for a portable house speaker, I highly recommend this. P.S. left one out in a dust storm in Utah once. Looked like another red rock when I retrieved it. No noticeable effects on performance.

Rated 5 out of 5 by from A must have speaker After compared both Bose & HK, finally decided to go with HK. Bass is perfect. Not too much, but not too crisp. Sound is obviously powerful. Clarity is okay, but if HK can make the acoustic clearer, nothing can beat it ! In addition that I love the design, I'm impressed that HK provides 1 adapter with so many cables for all types of outlet. I won't have to worry to look for new cables!

Rated 5 out of 5 by from Easy to set up. Awesome sound I have 2 onyx 3 speakers. After hearing one I had to pair it up. So I bought 2. I've been sitting in Newport Beach all morning in a little over five hours my speaker went dead. Used my cigarette lighter outlet in my truck and plugged the speaker in and it worked. I thought you could only use the AC power outlet from home etc. Anyways, sound is awesome. I paid 150 apiece forum well worth the money

Rated 5 out of 5 by from Excellent Sound Quality Great sound quality with elegant design and this speaker has pretty rich bass. The battery should have been better. But for this sound quality, I can compromise on battery.

My Onyx Studio 3’s power button keeps flashing even after charging via power adapter overnight. If I unplug the power adapter, the speaker would turn off after 10 seconds. Do I have to change the battery inside the speaker now? I haven’t used it much.

connect onyx3 with a 4 or 5 via dual? so i can pair both, is it possible?

Asked by: AhmadAlomran
Unfortunately, you would not be able to pair a Harman/Kardon Onyx Studio 3 with an Onyx Studio 4 and 5. This is because the Dual Wireless Sound featured in the OnyxStudio 3 only gives you the capability to connect to a second Onyx Studio 3 since the wireless dual sound feature only works on the same model. And the Onyx Studio 4 has a different connect feature called HK Connect that uses an app to connect the speaker to another speaker that has the same feature.

Asked by: Narek
You can purchase third party adapter chargers, just make sure that the output is at 19V@2A which is the required power input for charging the battery of the ONYX STUDIO 3.

First of, what a fantastic speaker! I have 2 questions: 1- Any way I can view what devices my Onyx Studio 3 is paired with? 2- How do I upgrade the firmware via USB?
