Onyx Studio 3 is rated 4.6 out of 5 by 68.
Rated 5 out of 5 by from Great portable unit I use this for crosses on my BMW 840Ci M62 on the centre back seat streaming Spotify through my Sony compact X and the sound is awesome with all windows and sunroof open. Would be better if I could connect a 12 volt DC direct into unit. Also is it Ok to leave it on AC adapter continuously at home.

Rated 5 out of 5 by from Sounds great... but sizeable. The sound is impressive, though the speaker itself was a little larger than I was anticipating. Regardless of the footprint, this is an excellent sounding speaker and I'm pleased with my purchase (it was a great deal at the sale price).

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!

I've just purchased this unit for my office and it's great. I just can't figure out how to stop it from interrupting the music when I get a phone call.  Even on silent phone calls come through and I need it not to do that

Asked by: Esp3
There are two ways to accomplish what you want to do. 1. You can go into your Bluetooth settings and select the ONYX STUDIO 3 settings and select ONLY the Audio option and deselect the Headset option. This will allow you to transmit audio from the phone without phone call interruption. 2. You can set your phone to do not disturb so that it won't ring at all.

Can this speaker be charged by USB?

Asked by: LDee
To charge the ONYX STUDIO 3 you need to use the power adapter and power cable included with the speaker to charge it. The USB port is only used for updating the speaker's software, when available.

I am trying to get my speaker to play but to get the sound to come out, we need to hold down the volume buttons! This issue happens when connecting via BT or AUX... Any ideas?

Asked by: Michele_w_1_L
What you are experiencing is certainly not normal. Please try to do a reset on your ONYX STUDIO 3 to fix your issue - Press and hold the "Volume +" and "Phone" buttons for a few seconds, the power button will turn red and the unit will turn off once you've released the buttons. This resets your speaker. If the reset does not help, please submit a case at harmankardon.com/contactus and our Customer Service Team will be glad to assist you.

Hi. I just bought my Onyx Studio 3, and the sound is amazing. My only question is whether I can always leave it connected to the power, or is it recommended to disconnect when not in use? Thanks.

Asked by: Bublitz
Yes, it is completely safe to leave your ONYX 3 connected to the power whether it is in use or not. It won’t damage the battery, but take note that using your ONYX 3 while plugged in will prolong the charging time.

I recently purchased the Onyx studio 3 and it sounds amazing. Can you leave this speaker plugged into the wall outlet always or will the battery get damaged by this?

Asked by: JohnnyCash
Yes, it is completely safe to use the ONYX STUDIO 3 while charging. This will not harm your battery in any way. You would even get the full power of the ONYX STUDIO 3 when running on electricity. The speaker is designed to play half its capacity when running on battery.

Which one should I choose, HK Onyx Studio 3 or HK Aura Studio? Thx

Asked by: lim9003
There are a few things to consider when choosing between the ONYX STUDIO 3 and the AURA STUDIO since they are completely differently designed. Portability – ONYX STUDIO 3 is portable; AURA STUDIO is not. Staging – ONYX STUDIO 3 provides stereo-sound while the AURA STUDIO provides 360° sound. Power – The ONYX STUDIO 3 and the AURA STUDIO are rated at 60W. If you are looking for precision, I would suggest the ONYX STUDIO 3 since this provides stereo staging which would sound more precise. It would be best if you get to listen to both speakers and decide from there.

How can i disconnect paired devices from my oynx speaker? Is there a way to disconnect from simply the speaker if i dont have access to the connected device?

Asked by: brian562
One way to do this is to place the ONYX STUDIO 3 back on pairing mode and connecting another device. This will let the new device take over the speaker and play its audio. Another option would be to reset the ONYX STUDIO 3, this will remove all previously paired and connected devices to the speaker - Press and hold the "Volume +" and "Phone" buttons for a few seconds, the power button will turn red and the unit will turn off once you've released the buttons. This resets your speaker.

Hello! I just bought the Onyx Studio 3 and both my two PC's cannot find it via bluetooth. What can i do?

Asked by: Ioannis
Please ensure that the ONYX STUDIO 3 is on pairing mode. To do this, while the unit is turned on, press on the Bluetooth button. The Bluetooth button would start flashing indicating that it is now ready to be paired. Re-check the Bluetooth settings of your PC’s and it should now be able to detect your ONYX STUDIO 3.
