what's the difference between the omni 20 + and the older omni 20 ?

Asked by: lee guan
The Omni+ speakers come with built-in Spotify Connect and Chrome Cast. Other than that, both have the same specifications. You may use the Spotify app and stream directly to an Omni speakers via Bluetooth.

Hi, I have just purchased Omni 20+ and 10+. I am also looking at an Onyx Studio 4. Can I somehow connect the Onyx with the Omni + series so that while streaming fex Spotify on the Omni + the Onyx will play the same audio?

Asked by: Jall
Unfortunately, the Onyx Studio 4 makes use of the HK Connect+ technology to another speaker. The Omni 20+ and Omni 10+ uses Wi-Fi and a local area network to connect to one another..

Good morning, I'm thinking of buying a horn, but I do not decide between the omni 20 and the Onyx Studio 4, I already have an onyx mini, so I can configure them for a stereo sound, but even with the two onyx configured, it's better the hd sound of this ??

Asked by: achp79
If you're looking for a portable speaker then the Onyx studio 4 is a good choice since the Omni 20+ needs to be connected to a power source to work.But if you're looking for a better audio quality then the Omni 20+ should be the one for you.

I cannot find the Spotify streaming service in the HK controller app, as it is mentioned above. I have 2 OMNI 20 (no plus)

Asked by: mark001
Hi The first generation Omni speakers do not support Spotify. You can use Spotify Connect on the 2nd generation Omni products ( Omni+ ), and restream from this new Omni+ to 2 first gen. Omni speakers. If you require further assistance, please contact our customer support

I have 3 Omni 20 speaker. I stream spotify via Bluetooth. Often I have connectivity issues (latest firmware). If I now buy one Omni 20+ speaker, how many speaker can I connect? Will the WIFI improve the connectivity?

Asked by: ifinno
Yes, you are able to pair the new Omni 20+ with the old Omni 20 speakers (master and slave, respectively). For every two first generation speakers, you need at least one Omni+ speaker. Although the software for the Omni+ speakers have improved, there are no changes to Wi-Fi connectivity.

Does the 20+ have a built-in battery ?&#65279; In my local store I was told yes, however, ChrisZA asked the same question below to which you replied, that it has not. Please clarify.

Asked by: goodnightvienna
The OMNI 20+ is not designed for portable use and therefore does not have a battery. Maybe the sales rep was thinking of the OMNI 50+, which does have a battery and is splashproof and weatherproof, so it can be used outdoors.

Does the Omni 20 have to be connected to a power source or has it got a battery source for portable use?

Asked by: ChrisZA
The HK Omni 20 needs to be plugged in to a power outlet for it to function. It doesn't have a built in battery inside.

Could be posible to pair an Omni 20+ and a old Omni 20 as stereo pair (being Omni 20 + the m&aacute;ster and old Omni 20 the slave)?

Asked by: Danmal
Yes, you may definitely pair your Omni 20+ with the old Omni 20 (master and slave, respectively), since the only features added to the Omni + series are Spotify Connect and the built-in Chromecast. There were no changes made on the wireless pairing.
