Onyx Studio 3 is rated 4.7 out of 5 by 65.
Rated 5 out of 5 by from Great portable unit I use this for crosses on my BMW 840Ci M62 on the centre back seat streaming Spotify through my Sony compact X and the sound is awesome with all windows and sunroof open. Would be better if I could connect a 12 volt DC direct into unit. Also is it Ok to leave it on AC adapter continuously at home.

Rated 5 out of 5 by from Sounds great... but sizeable. The sound is impressive, though the speaker itself was a little larger than I was anticipating. Regardless of the footprint, this is an excellent sounding speaker and I'm pleased with my purchase (it was a great deal at the sale price).

Rated 5 out of 5 by from A must have speaker After compared both Bose & HK, finally decided to go with HK. Bass is perfect. Not too much, but not too crisp. Sound is obviously powerful. Clarity is okay, but if HK can make the acoustic clearer, nothing can beat it ! In addition that I love the design, I'm impressed that HK provides 1 adapter with so many cables for all types of outlet. I won't have to worry to look for new cables!

Is it possible to charge the onyx 3 with portable power bank?

Asked by: javs
Unfortunately, no. Usually, portable power banks output 5V at 1A~2A. To charge the ONYX STUDIO 3 properly, you would need a minimum of 9V 2A. It is best charged with the supplied adapter for charging.

Hi. First of all I want to say that the Onyx Studio 3 is 100% fantastic. I have nothing negative to say about it them.   In dual mode they stay connected through both floors of my home. Does dual mode use Bluetooth ? What is the max range between them?

Asked by: bgeli13
Thanks for sending your feedback. Yes, the Wireless Dual Sound feature present on the ONYX STUDIO 3 uses Bluetooth. Bluetooth’s maximum range is 10 meters on a perfect set-up without wireless interference (i.e. other wireless devices, concrete walls/divisions). This decreases significantly in a typical home set-up.

Would I be able to pair the onyx studio 3 with a microphone, to another onyx studio 3 without the microphone? They look slightly didn't know if they needed to be exactly the same!

Asked by: Donk
No, You can only connect 2 ONYX STUDIO 3 with each other. However, If you play music from the source via wired connection, you can connect the ONYX STUDIO and the ONYX STUDIO 3 together using an AUX splitter cable which can be purchased at most electronics stores.

how do I connect my iPhone 7 to studio 3

Asked by: gary3103
To put the ONYX STUDIO 3 in pairing mode, by pressing the Bluetooth button. An audible tone would indicate that the ONYX STUDIO 3 is now on pairing mode and the Bluetooth button would start blinking. While the speaker is on this state, re-check the iPhone 7’s Bluetooth’s settings and it should not list the ONYX STUDIO 3. Connect, and enjoy your music.
