Omni 20 is rated 3.6 out of 5 by 23.
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.

I would like to stream HD audio from my Tidal HiFi subscription to the Omni 20. 1) Can I stream 1411 kbps audio from Tidal through the HK app? 2) Can I stream Master quality MQA from Tidal through the HK app? 3) Will Harman implement full MQA decoding?

Asked by: Psykoakustik
1 and 2. The music services within the HK App are links to launch the music services app. There is no dependency on the HK App. The HK App is only required to set up the speakers. 3. Yes. Harman Kardon: The Harman brand is upgrading its wireless multiroom-audio products, shipping in June, to support 192/24 wireless streaming, up from 96/24, thanks to the addition of 192/24 DACs and wider bandwidth dual-band Wi-Fi. The Omni+ products ship in June.

Can I stream music from my laptop with windows 10 over wi-fi (not bluetooth)?

Asked by: dmarecos
No. The OMNI 20 can only be played through your home wireless network from an Android or iOS device via the HK Connect Application that can be downloaded for free on each platform&rsquo;s app store. The only way you can play audio through the OMNI 20 from your laptop is via Bluetooth or wired connection/auxiliary.

Hello, Do these speakers connect to a NAS device? Or, just bluetooth from a mobile device?

Asked by: ccrc
The OMNI 20 can be connected to a source device three ways - Auxiliary/Wired connection, Bluetooth and through a home wireless network via the HK Controller App. The HK Controller App is only available for iOS and Android devices, so as of currently, playing off a NAS is not possible.

I'm about to use 4 of them in a pastry, is this possible to link them all? how many Omni 20s can be linked as a maximum? Thanks.

Asked by: Hero
Yes. By design, the OMNI speakers (OMNI 10, OMNI 20 and ADAPT) are made to connect to each other under one home network. You can connect up to a maximum of six of these speakers.

Hello. I have some problems with the app and the wi fi connection. It plays one song and then I'm not able to play another one. It starts searching and doesn't play the next one. Thanks

Asked by: Ignacio
What you are experiencing is not normal. If you&rsquo;re playing a song from an album and the next song doesn&rsquo;t play, the speaker must be acting up. Please try one of the following steps to possibly fix the issue. -Remove your pairing from your phone/table and reset your OMNI speaker and repair again. -Check and download the latest software of the app and speaker If none of these things work, please submit a case at www.harmankardon.com/contactus and the Customer Service team will be more than happy to further assist you.
