Does this connect with Amazon Echo Dot for use with Alexa?

Asked by: CMH1
Yes you can. Since the Echo dot can pair to bluetooth speakers, this should be no problem. Simply put the Onyx studio 4 in pairing mode and use the bluetooth settings in Alexa app to connect to it.

Can I use the Onyx 4 in the bathroom while I take shower? Or will this damage the speaker? Great product - thanks.

Asked by: Mike G
Hi, The Onyx studio 4 is not humidity resistant as this is not designed to handle high humidity environments. water/Steam/vapor(due to a hot shower) can lead to condensation and if it gets heavy enough, it will cause damage to the speaker.

Is there a way of using the HK Connect stereo feature (with 2 Onyx speakers) using a BT connection with a computer (Win 10)??

Asked by: Alex M2
The HK Onyx studio 4 can only be set to stereo mode by using the HK Connect App by your phone and cannot be done through the Windows 10.

Hi.  I just got an HK Onyx studio 4 and noticed that you can pair it with another speaker.  Two questions:  1) Can you pair it with more than 2 speakers, and 2). Will it pair with other Onyx speakers such as he Onyx Mini?

Asked by: Cran
Thank you for your questions. The HK Onyx studio 4 has the HK Connect+ feature which allows you to connect more than 100+ devices with the HK Connect + feature. The Onyx mini does not have this feature and would not be able to connect to the Onyx studio 4.

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.
