Rated 5 out of 5 by from Clarity that you have never heard before! Purchased this today; tested it across many different genres and instrumental platforms; I can hear with awesome clarity not just the vocals but I can hear instruments I never heard before; listening pleasure is probably the best I've heard for a portable Bluetooth speaker; frequency range and noise to sound ratio is equally awesome; I confess I love it! 10/10

Rated 5 out of 5 by from Crystal clear and great bass I purchased the item through Amazon and I'm glad I bought two because of the dual capabilities. Well worth the $300 between the two of them with all of the music and videos I am always watching.

My Onyx Studio 3 stays plugged in all the time on a very high shelf. Is there a way to power it on remotely because climbing up there to push the power button is not fun. Thanks

Asked by: Tom1960
No, There's no way to turn the power on remotely on the HK Onyx Studio 3.

Hello, I have the Harman/Kardon Onyx 3 connected to my macbook pro, is there any way I can stop it from auto connecting when I wake my macbook from sleep without having to turn off the Onyx? Thanks in advance!

Asked by: Blueyo
Aside from completely turning the ONYX STUDIO 3 off to avoid automatic pairing, the other way is to turn off your MacBook Pro's Bluetooth so it will not wake up the speaker from Stand By mode.

¿How long is the guarantee for a refurbished product? I am interested in the Onyx Studio 3. Thanks.

Asked by: DavidHidalgo
Hi, Thank you for your question. All refurbished products have the same warranty as a new one. Depending on where you are located, but in Europe you have two years warranty in most countries and since you are based in the UK, you will have two years.

Is the Onyx 3 capable of connecting to the wireless Harman Kardon sound bar and subwoofer so we can use the sound bar in the house and the onyx 3 on the patio?

Asked by: TamK
The Harman Kardon soundbar and the Onyx Studio 3 are standalone sound system. It will only connect to a particular source and could not be link to each other.

Can I connect Harman/Kardon Microphone System to the Onyx Studio 3? Would it work as Karaoke system?

Asked by: Anilee13
Thank you for taking time in asking your question. The microphone system or the EZset in the HARMAN/KARDON is use to calibrate the receiver to match the loudspeakers, optimizing sound reproduction. The EZ set will not work for the ONYX STUDIO 3 since this microphone is solely dedicated in calibrating the receivers and speakers.

Is it possible to turn off de startup sound? It wakes the kids and is totally useless because the lights indicates the unit is on. Please help, love this product but wil return it if this can't be turned off.

Asked by: Dennis123456
No, we cannot disable the phone notification sound on ONYX STUDIO 3, the system audio prompts volume cannot be changed. The speaker has the power save feature meaning if there is no audio detected for 10 minutes the speaker will turn off.
