Does the Onyx 4 automatically shut off when connected through Bluetooth? I'm intending to connect it to my Google Home Mini for a better listening experience. Can the Google Assistant feature be activated through voice?

Asked by: Zelaf
Hi! No, the power saving feature cannot be disabled. Whenever the speaker is not being used for about 10 minutes, it will automatically go to power saving mode. As for the voice assistant, you may use it from the HK Connect app. On The HK Connect App, tap the Voice Assistant to activate Siri or Google Now. Then press the Phone button on the speaker to activate Siri or Google Now. Please make sure the Siri or Google Now is enabled on your phone.

can you link the sabre 35 with the oxyx 4?

Asked by: Douglas S
Hi! No, Onyx studio 4 and Sabre 35 cannot be connected together because the soundbar does not have the Connect+ feature which the Onyx has.

Is it posible to pair Studio 4 with Studio 3?

Asked by: APMG
Unfortunately, you would not be able to pair a Harman/Kardon Onyx Studio 3 with an Onyx Studio 4. 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. 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.

Hello, I purchased a smart TV I need to add a s.s. system. I currently own an onyx studio 4 im undecided weather to get a sound bar or get another onyx st. 4 and connect both to my new TV via bluetooth. Which is a better option for optimal

Asked by: Fred1024
Connecting two Onyx Studio 4's directly to your TV would depend on your TV's capability to separate the left and right channels of your source to the two speakers. We recommend verifying this feature to manufacturer of your TV to verify this. Regarding speakers to be connected to your TV, we usually recommend using a soundbar instead. We highly recommend checking our new Enchant 800 and Enchant 1300 soundbars and they sound amazing. You can find more details about them here on this link: https://www.harmankardon.com/soundbars/

how is the performance of this speaker compared to the JBL Xtreme ?Having a tough time debating between these 2.

Asked by: Haren
That's one tough question. Both of them sound awesome but let's make this easier for you to choose. If you are the type of guy who wants a more bassy sound, the JBL Xtreme is just for you. But if you want a crisp,detailed sound then the HK Onyx studio 4 would be your pick. Or better yet, why not get both and enjoy each type of music at different times.
