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

Is there a way to adjust the bass? It's too much for my liking.

Asked by: stephie
To decrease the bass try placing the speaker further away from the wall or a corner.

There seems to be a slight 0.5 second delay in the sound which is annoying especially while watching videos. What is the latest firmware and is there an update coming that should fix this? And how do I install this?

Asked by: HK12
Hi! The Onyx Studio 4 is designed to play audio files only and not necessarily videos. Whenever you start the video and audio at the same time, the audio will lag behind by the length of time it takes the Bluetooth hardware to receive, process and output it which is known as Latency. You won’t notice this lag if you’re listening to music, but if you’re watching a video the sound may be marginally out of sync. Latency varies depending on the hardware and software setups you have. The latest firmware version is 3.3.

I’m having a bit of a problem with mine. It currently powers up OK and connects to devices fine. I’m however not getting any sound. When it powers up there’s always an sound and also when it connects to device. Now none of the sounds at all.

I purchased my Harman almost a year ago. Love this speaker however I’m noticing I’m only getting about 3-4 hours of battery life not the full 8 like I used to. Is there something I can do to fix this? Stinks when it dies out while at the beach.

Hi, Is it possible to pair onyx studio 3 with onyx studio 4? I have one psc of onyx 3 and want to buy one more to play 2 speakers together.

Asked by: Miks
Hello! Unfortunately the Onyx Studio 4 would not be able to connect to the Onyx Studio 3 since the Onyx Studio 4 has the HK Connect+ that allows you to connect to 100+ speakers with the same feature while the Onyx Studio 3 has Wireless Dual Sound which is a different technology from the HK Connect +. HK Connect+ is not compatible with Wireless Dual Sound technology.

My 6 mth old Studio 4 is has been working brilliantly, however I turned it on to have it play muffled music. Have tried re-pairing to my computer, pairing to my mobile, with power cord attached and disconnected. No joy. Not the quality I was expecting.

Asked by: AndreK
Hi Andre, I would like to advise you to return to the store where you have bought your HK Onyx Studio 4, so this can get checked for you.
