Rated 5 out of 5 by from Great speaker Sound is great! After testing a lot of other models I can tell, best sound quality for its category. Two improvements needed, add micro usb or even better usb-c to charge with any charger. And secondly, improve integration with iOS devices to display remaining battery percentage.

Rated 5 out of 5 by from Great mid-range bt speaker! In Europe is priced at 200 euros and it's hard to find anything better in that price range. Balancing it with some eq is a must, otherwise bass is way too overwhelming, mids are recessed and highs are not well pronounced... But when you play with it for a few days, man it shines! Nice sound stage, punchy bass, good mids, solid highs and even some stereo separation... Planing to buy another one these days. That should be impressive!

Rated 5 out of 5 by from AWESOME SPEAKER Got this as a Christmas gift from my brother and I love it. It's nice, loud and crystal clear. I've had other devices that were just as loud but distorted and not clear.

I wondered if onyx 4 is water resistant and approved for use in bathrooms

Asked by: Guest5
The Onyx Studio 4 is not waterproof so you cannot splash it with water as it may damage the speaker.

what is the difference between Harman Kardon Onyx Studio 4 and Harman Kardon Onyx Studio 3? Does Harman Kardon Onyx Studio 4 has 3.5 mm Aux input also ?

Asked by: Guest
Aesthetically speaking, they both look the same. In terms of performance, the main difference is the music playing time for each speaker - the Onyx Studio 3 has an audio playback of up to 5 hours and the Onyx Studio 4 has up to 8 hours (varies by volume level and music content). Another one of their main differences is the speaker connectivity: the Onyx Studio 3 offers the Wireless Dual Sound feature which allows you to connect a maximum of (2) speakers with the same feature for amplified sound whereas the Onyx Studio 4 has the HK Connect+ feature that allows you to connect to as much as up to 100 speakers with the same feature. The Onyx Studio 3 cannot be connected to an Onyx Studio 4. The Onyx Studio 4 does have an Aux Input.

HK Onyx Studio 4. I'm using it with my Windows 10 machine. My PC often disconnects it and often when I reboot my PC it doesn't see the speaker until I have to go through the bluetooth steps. Can I hardwire it with a USB cable. Service port ?

Asked by: JayP
No, the Onyx Studio 4 cannot be connected to a Windows 10 device through the service port and use that connection to play media files from the device to the speaker. You can use an aux cable to connect it to a 3.5mm port on your device instead.

Great speaker, but HK Connect+ app is not even beta quality. Stereo mode drops all the time, if app manages to find two speakers. Is the app in active development and can we expect that these serious usability issues gets sorted out at some point?

Asked by: sapesa
The same problem continues. I have not been contacted as promised. When will the faulty apps and/or firmware be fixed?

Is there a way to mate this speaker to my TV

Asked by: Saul
Yes you can, You can either connect it via bluetooth or connect it via Aux. Since most of our bluetooth Speakers are designed more on Music and not video, please do expect latency when playing videos/watching tv. I would suggest using a wired connection for the Onyx studio 4 when connecting to the TV.

What are the specs for the power adaptor? Would the same work internationally i.e. 220 - 240V?

Asked by: Jacob1117
The power supply for the ONYX STUDIO 4 is set to Auto Volt so you can plug the unit into either a 110v outlet or a 220v outlet without any issues.

Is there anyway to change the name of one of my speakers (studio onyx 4) In Bluetooth setting? So that I know which speaker I am connecting to?

Asked by: Chris LA
Yes you can but it would depend on your phone if it can allow you to change the names of the Bluetooth devices connected to it. The changed name will only appear to that specific phone.
