Amazing sound - bigger than I had anticipated
on December 5, 2025
Posted by: planogreg
This is a Christmas present for my son, but I had to test it, to make sure it worked, and the sound is amazing! it is bigger than I thought it would be.. but that is probably why the sound is also "big"

can't access bass and treble controls, need help thanks
Response from harmankardon.nlBy Customer Support, December 5, 2025
Thanks for bringing this to our attention. We recommend using a third-party music app with a built-in equalizer to modify the bass and treble.

Great portable speaker! The deep bass fills the room with sound and the speaker is great looking.

Very Small Bluetooth Radius
on November 26, 2025
Posted by: moonmeg
The audio quality and bass is great. My biggest issue is the bluetooth feature. As soon as I leave the room the music starts to disconnect. Have never had a speaker with such low bluetooth radius. I don’t know if I just got a faulty product.
I would recommend this to a friend!

Thanks for your feedback on our Harman Kardon Onyx Studio 8. Make sure that your source device and speaker are within the Bluetooth range of 10 meters. Also, please don't place the speaker too close to the Wi-Fi router and appliances like microwaves that can interfere with the connection. If the issue persists, we'd like to work with you directly to address the issues you're experiencing with your Harman Kardon Onyx Studio 8. Please contact our customer support.
