Rated 5 out of 5 by from I love this Bluetooth speaker! I just purchased one yesterday from Sprint, and I have to say that I'm very surprised by the clear sound & excellent bass that this speaker puts out. It's the best Bluetooth speaker that I've come across. It's portable with a handle too, so that you can take it to the beach with you after a full charge. Superb listening experience!

Rated 5 out of 5 by from Super loud and DEEP BASS The speaker can get extremely loud. Like really loud. The bass is very clean yet deep, and it keeps up with the rest of the audio, it does not overdo the highs or mids. Utter beauty

Hi! Yes, you can connect other speakers with the HK Connect + feature along with the Onyx Studio 4. But connecting a wireless subwoofer is not possible.

Using an avantree oasis transmitter connected to my stereo the Onyx speaker constantly cuts out even at 2 feet away. Yet my Bluetooth headphones can go up to 100ft away without cutting out once. Any suggestions?

How do I connect 2 onyx 4 speakers. Are there step by step directions for this. What buttons do I press on each speaker in what order? tried pressing the connect button on the 2nd speaker. Tried BT on 2nd speaker, then connect. Tried every possible combo?

Asked by: SrBruno
To use the HK Connect+ feature for two Onyx Studio 4 speakers, first keep music streaming to one speaker. After this, press the Connect+ button on your speaker then press the Connect+ button on the nearby Onyx Studio 4 speaker to connect.

Hi I have a white onyx studio 4 . It has got really dirty how do I clean it ? Also how do I use connect + feature .? 

Asked by: Karan khemani
We recommend using a microfiber cloth to polish the high-gloss surfaces, and a vacuum with either a stationary brush attachment or hose to clean the speaker grille. Do not use water to clean the products. To use the HK Connect+ feature for two Connect+ speakers, first keep music streaming to one speaker. After this, press the Connect+ button on your speaker then press the Connect+ button on the nearby HK Connect+ compatible speakers to connect.

While my speaker is plugged in, I turn the side button to on, it lights up, then shuts down after about 2 seconds.
