Harman Kardon Onyx Studio 4 is rated 4.4 out of 5 by 68.
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.

Rated 5 out of 5 by from Great Gift I bought this as a gift for my son during the sale. BEST decision seeing as Sprint wanted $489.99. He wasn’t getting it at that price. Wish I would have pre ordered the blue. Anyway the sound is very good and clear. Waiting on your next sale.

My Onyx 4 mutes itself periodically when using through bluetooth from my computer. Pressing the up od down volume button on the speaker unmutes it. Is there a reason for this or a fix?

I have two Studio 4. They work lovely. I have set them in stereo mode using the app. When they are turned off over night, do I need to reset them to stereo again with the app next time i use them or do they remember the last mode they were in?

When I use the aux input (from a computer headphone jack), and the music gets quiet, the speaker will stop playing until the song gets louder. Is there a setting I can change to fix this?

When I play music through the aux cable, there is often a slight delay between when a song starts and when the sound first comes out of the speaker such that I miss the first second or two of the song. Is there a setting I can change to fix this?

Hello, I have noticed that when a song starts, there is about a 0.5-1.0 seconds of delay before it can be heard. Like a gate's threshold that has been set too high. This is present through Bluetooth/3.5mm cable with variable volume. What can I do? Thanks.

What is the difference between the Onyx 3 and 4?

Asked by: Jonas78909
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.

got the harman/kardon onysx studio 4 speaker yesterday, and it was working perfectly fine for the first half an hour or so after taking out of packaging, until the battery died. Won't charge at ALL. Do i need to replace it?
