Omni 20 is rated 3.4 out of 5 by 27.
Rated 5 out of 5 by from Great Sound Quality from such a small package. I purchased this as a gift for my mother and she loves it. The sound quality is amazing. Sounded so well I purchased three more Harmon/ Kardon products from best buy for personal use and as a gift to my wife and niece. All of whom love it.

Rated 5 out of 5 by from The bass is unmatched I really wish it didn't have to be plugged in to function, but if you can get over that downside, this speaker is amazing. It looks classy and sounds classier.

Rated 5 out of 5 by from Why did I uy an Onyx again? Bought both this and an Onyx. This for me and the Onyx for my fiance and I to have on the go. (We live on the shore so we go to the beach a lot). This sounds exactly like the much more expensive Onyx leaving me to wonder if it's actually worth the extra $200. They're both amazing speaker. Bass is excellent (not overpowering) and mids and highs are clear. The app could be a better though, but we don't really use that much anyways.

Why hasn't Harmon/Kardon added support for Apple Music subscriptions for play over wifi? I can play them directly from the Apple Music app over wifi, but not through the controller app.. which keeps me from being able to control multiple speakers in home.

Asked by: J__lee
Unfortunately,&nbsp;Apple did not provide the added support to add Apple Music to the HK Controller App.

I just bought a HK OMNI 20 speaker a year ago. Now i found that when i increase volume to around 80%, the speaker will come out some noise like the speaker crack sound when the songs with strong bass. Isn't it can't support strong bass?

Asked by: Faradayko
That is normal. Driving too much bass on high volume levels to the OMNI 20, or to any speaker in general, causes distortion and is usually a sign to lower down your volume. If you are using an EQ to boost bass, please set it to flat. This should minimize the distortion at louder volumes.

This worked for a while, and now it'll barely make it through one song before the sound degrades to nearly all static. Reset doesn't work. It worked fine for hours at a time for many month. Any suggestions?

Asked by: JBATX
I&rsquo;m sorry to hear that you are having issues with the OMNI 20. If resetting the unit did not fix the issue, try doing a factory reset. Press and hold the reset button for 5 seconds. All product settings, Wi-Fi, and Bluetooth connections will be erased. If you are still experiencing issues, please submit a case at www.harmankardon.com/support-product.html and our Customer Service team will be glad to assist you.

What is the recommended mounting bracket/stand for mounting the Omni 20 to a wall?

Asked by: vballguy20
The two mounting screw holes are 3mm in diameter and 60mm apart. You can purchase universal type wall mount systems that will work for these speakers. 1 good company to check out would be Omni-Mount.
