Rated 5 out of 5 by from Perfect sound for any music genre I mainly listen to jazz and heavy metal and oh boy does the OS3 deliver on the sound quality. You can hear every instrument clearly, every note, every chord. Such a fanboy for harman/kardon products from the date i bought this.

how do i know when the onyx studio 3 is completely charged?

Asked by: Ray Kappel
With the Onyx Studio 3 switched ON, the ON/OFF switch light flashes while the unit is charging. If the unit is switched OFF, no indication shows that charging is taking place, but charging still takes place. When charging is complete, the light becomes constant. There is no battery status indication, so it is not possible to follow the power level of the battery.

How can I use the microphone? I tried to connect through bluetooth with my Windows 10 computer and with my Android phone, but I cannot get it working. I would like to use it for Skype and for mobile phone calls. Could you explain, please?

Asked by: Reinier
The ONYX STUDIO 3 supports voice conference apps like Skype when connected to any smart devices via Bluetooth. When connected to a computer/laptop via Bluetooth, use the latest version of Skype and ensure that the Bluetooth's software and drivers on your PC are up to date and you will be good to go. Make sure that the ONYX STUDIO 3 is on pairing mode. To do this, while the speaker is on, press the Bluetooth button and the light indicator should start blinking and a tone will be heard indicating that the unit is ready to be paired. If this doesn’t help, I noticed that you are located in Luxembourg, please contact the store where it was purchased and they will be able to help you.

Can the Onyx Studio 3 be connected to a cd Player? I have the Pro-Ject MaiA CD Player and I was wondering if both could be paired via cable. Thanks!

Asked by: marisneip
A source device can be connected to the ONYX STUDIO 3 via 3.5mm audio cable. If your CD player has a headphone jack or an RCA outputs, please run a cable from it to the ONYX STUDIO 3's Aux input.

Is stereo playback through 2 onyx studio 3 speakers possible?

Asked by: hughgotit
Would there be any possiblilty to have a firmware upgrade in the future to have an option to play it as right and left channel? Would be very nice if it is capable of doing so.

My onyx studio 2 does not stay on after removing the plug, even after it's been plugged in all night. Does it matter if it is on or off when plugged in to charge?

Asked by: Barbara P
The ONYX STUDIO 3’s LED indicators are ON when charging, and turns off when fully-charged. It is possible that the speaker has an issue and is not taking a charge, thus shutting down when un-plugged. If this is the case, please submit a case at www.harmankardon.com/support-contact.html and the Customer Service team will be more than happy to assist you.

I've had mine about 2years and it just stopped working the other day. Will Not Operate via Battery or while plugged in. Power Will not come on. Tried multiple outlets - any other tips to check?

Asked by: KPTOMORY
It seems like your ONYX STUDIO 3 has bad power supply or the connector is bad. Try using a different charging cable and a different power source. If this cannot be prevented, please submit a case at www.jbl.com/contact-support.html and our customer service team will be glad to assist you.

While charging the onyx s3, there is no indication showing that the unit is charging or is finally charged. How do you know how long to charge this?

Asked by: Planetantonio
The white light indicator on the power button would stay constantly lit when the ONYX STUDIO 3 reaches full charge. While the battery charge time for the ONYX STUDIO 3 from 0-100% is estimated at 5-hours. Please know that it is healthier for the speaker to receive small frequent charges whenever possible rather than 0-100% in one go.

Is it ok to leave the speaker on continuously all day, even if it's not playing anything.

Asked by: Nickkk
Yes, leaving the ONYX STUDIO 3 plugged in even if it’s not playing will not harm the battery nor the speaker itself.
