Onyx Studio 3 is rated 4.6 out of 5 by 128.
Rated 5 out of 5 by from His NEW girlfriend! I bought this as a Christmas gift for my husband who is a DJ. Since its arrival, I am now the side-chick. LOL! He absolutely loves it and rightly so...The sound is so crisp...can't believe something this small can products sounds where you can hear the highs and the lows so clearly. I am disappointed that this model has been discontinued :-(

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 Beats Pill killer I bought two so I could pair them and I love the sound quality.

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.

Rated 5 out of 5 by from Amazing!! For a refurb unit, the sound it produces is amazing and C & C (Crisp and Clear). Design looks simple but high end. Connectivity is a breeze. I use this speaker with my tv and it’s just what i needed. the only drawback is it does not have it’s own remote which is fine with me because i can use the remote of the audio source. At the end of the day, it was a great purchase for me.

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.

What kind of charger do I need to buy for this speaker? I have had it for about 2 years and the charger stopped working for some reason. I searched on google about this but it turns out there are different dimensions to the charger. Which one do I need,

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.

Can I connect multiple Onyx Studio 3 together to create a muti-speaker system?

Asked by: nintando
No. The Onyx studio 3 has a dual wireless sound feature. Dual Wireless Sound only has the capability to connect no more than 2 speakers at a time. Both speakers must be the same model. Only 2 Onyx studio 3 speakers can only be connected at a time.
