Is the Onyx compatible with a Bluetooth microphone?

Hi, I just want to understand the difference between HK Onyx, Onyx Studio 2 and Onyx Studio 3 and which is right for me (key use: outdoor BBQ, pool side, excursions, etc.) 1. What are the differences in features? 2. What are the model launch years

Asked by: shariqmunir
The ONYX STUDIO 3, ONYX STUDIO 2 and ONYX have identical drivers and are both rated at 60W. The difference is, if the ONYX STUDIO 3 is running on battery, it will only output half of that rated wattage (half as loud) to save battery. You can only use the full 60W when running with the power cable plugged in. Second, the design, the ONYX uses a steel ring while the STUDIO 2 and 3 has legs to stand up. Third, the connectivity, the ONYX STUDIO 2 only has Bluetooth connection, ONYX STUDIO 3 both has auxiliary and Bluetooth and ONYX has both and wireless connectivity that can be connected to your Home Network for DLNA/Airplay. Fourth, the OnyxStudio 3 offers Wireless Dual Sound. This allows two Studio 3’s to wirelessly connect to each other, or to the Go+Play Mini and Onyx Mini, to play music out of them simultaneously.

I bought my speaker one year ago and never had a problem. Just use it four or five weeks per year. All of a sudden started just working if plugged in to a power outlet. Looks like the battery does not charge anymore. Do I need to replace the battery?

Asked by: JoaoJ
I'm sorry to hear that you are having issues with the ONYX. Unfortunately, you cannot replace the battery. What you can do is to try plugging the charger to a different wall outlet or try a different charger. I noticed that you are in Portugal. If you are still experiencing issues, please contact the store where you purchased it from and they will be able to help.

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.
