Hello i just bought the onyx 3 speaker it was great with my husband samsung phone but does not work with huwai honor 5 my phone i can find the device on my search bluetooth in mobile? Any reason why? How can i fix? The same for iphone does not work

Asked by: Janna
You may try doing a reset on your ONYX STUDIO 3 by turning it on and holding down Phone button & Volume + at the same time until it shuts off. When you power it back on, it has been reset. If you have connected the device to the speaker, please make sure that you forget the speaker on the source device Bluetooth list. Then you can try to pair again. Furthermore, please also check Huawei Honor 5x bluetooth issues, it might also help you out correcting the issues. If this doesn't help, please submit a case at www.harmankardon.com/support-contact.html for information regarding your warranty options.

Are these speakers compatible with google chromecast?

Asked by: CKNU
Unfortunately, Chrome cast would not work on the ONYX since the USB port is used for charging and Wi-Fi setup with iOS devices.

Hi! My Onyx stops playing audio for ~5 seconds every other ~30 second while connected to my pc (Windows or Linux) using a mini-jack cable. It plays normally only if connected to my Android phone using a Bluetooth. What could be the problem?

Asked by: justgos
While connected via aux cable, make sure that the volume level on your PC is at least 70% so the ONYX can continuously detect the audio signal and adjust your desired volume on the speaker. Setting it lower than that activates the power-saving feature. If it does the same, you may try using another mini jack cable as the one you currently use might have gone defective. If you still encounter the same issue, please submit a case at www.harmankardon.com/contactus and the Customer Service team will be more than happy to further assist you.
