I have issues with multiple Onyx Studio 4 units, using connect+. They can stutter, or drop off. (very irritating to listen to) I tried the app and did not see any firmware update. The units are only 8 feet apart. Any suggestions?

Hello. Is it possible to pair my Onyx studio 3 with my new Onyx studio 4? I cant figure it out..

Asked by: Chrissy86
Unfortunately, the Onyx Studio 3 can only be paired with one other Onyx Studio 3 through the Wireless Dual Sound technology, while the Onyx Studio 4 can connect to multiple Onyx Studio 4s using the HK Connect+ technology. They cannot connect to one another since they use different technologies.

Should I charge battery before first use?

Asked by: Mike68
The Onyx Studio 4 comes with a factory charge when brand new, but it varies. With this, there is really no direct time-frame that we can provide for an initial charge. Unlike older devices that needs a certain amount of time plugged in initially, batteries now are better and does not require this. To keep the battery healthy, it is not advisable to drain the battery before charging it, small, frequent charges are better than charging it 0-100% at a time. Battery charge time from 0-100% is 4.5 hours using the cable provided.

The tablet I am trying to pair with provides a PIN that it requires be entered from the speaker. Obviously, this is not possible since there is no keyboard. There is no setting that I can find on the tablet to disable the requirement of PIN verification.

Asked by: Terri
There's no pin code required for the ONYX STUDIO 4 when pairing it with any Bluetooth enabled audio source device. It would normally be the source that is requesting for the pin. Try entering "0000," "1111" or "1234" when your device asks for a PIN. These are some of the most common default Bluetooth PINs.

The connection quality between the two speaker is awful. I bought two this weekend and I’ve tried every pairing scenario possible and cannot get non choppy and scratchy sound when I use the connect feature. I’ve tried my brand new laptop. How to fix?

Is the speaker stereo for itself or I need a pair for stereo streaming?

Asked by: MAR1
You need to have 2 Onyx studio 4 and the HK connect app in order for it to be set in either party mode or stereo mode.
