Omni 20 Plus is rated 3.9 out of 5 by 7.
Rated 5 out of 5 by from Surprised I was very surprised at how the speaker sounded and the bass also. I am very happy with my purchase. The only thing I wish the black speaker was in stock when I ordered but oh well. Oh yes and I wish it came with a remote.

Rated 5 out of 5 by from Great Sounding Speaker The speaker sounds amazing for its size. Bass is very deep and rich sounding and speaker fills a room with sound easily. The Omni 20+ has 4 speakers in it. 2 90mm woofers with 15mm tweeters. Setup is very straight forward if you want to have it be on the wifi. Bluetooth is easy to pair. You also have a 3.5mm jack on the bottom so you can wire in as well. Speaker has wifi and ethernet connection for setup of your choice. Over all, would recommend the speaker.

Rated 5 out of 5 by from Powerful at a Great Size Dimension I didn't realize this BT Speaker would need some break-in time. Now, with about 100 hours of streaming music, it continues to sound better all the time! My friends marvel at it as well and want one as soon as hearing it perform. And it's very attractive besides sounding great. Really pleased with this audio device!

Rated 4 out of 5 by from Excellente product but App is really awful Excellent product but App sucks! How HK Company who develops premium speakers with a first level sound offer this awful and old App? If you read the comments of consumers you will see a lots like this. Problems with Wifi connection, with first setup Wifi, detection of speakers, and so on. I hope to see an App update with best features and a design in the same level of your products. Thanks!

Hi, I would like to know if the speaker has some kind of lag streaming via bluetooth sound from a movie. I read about issues from users saying that when they cast the audio of a movie to the omni 20+ the sound was 1.5 seconds delayed. Is that true?

Asked by: Maximiliano
Yes they all do when watching a video or YouTube video, not music, I have 2 Onyx studio 4s and same thing.

I have a Omni 20 plus and have been experiencing audio lag of around 1.5 secs when I connect it to my TV using aux cable. Is this normal? Any solution?

Asked by: rkalra
same here, disappointed. Also when connected with my smartphone (both wi-fi or bluetooth) the music stops several times and this is happening repeatedly. Disappointed!

How many speakers can be connected together? if i mix omni20 and omni20+ with wi-fi streaming

Asked by: Kaiser_soze
There is no limitation on the HK Controller App on how many OMNI and OMNI+ can be grouped together. But the connectivity would depend on the bandwidth of your wireless router, if it would be capable of supporting x number of speakers.

about a month ago my HK Omni 20 started buzzing, it will work great for about 2 minutes then it starts the buzzing. I am hardwired in and have used it on different computers to no avail.

How can I connect my Omni 20 Speaker to the Amazon Alexa Echo Show?

Asked by: Rosa
You maybe able to do that over Bluetooth. I connected my Echo Dot to it by holding down the Bluetooth button on the speaker to enable pairing mode. then said &quot;Alexa Pair&quot;. You can also use the alexa app to set it up.

Does the omni+ series support apt x over bluetooth (or is there any other mobile HK speaker except onyx that do?

Asked by: Magnus M
No, Apt-X is not supported, and neither is AAC. The standard SBC codec is used in the Omni 20+.

Omni 20+ mentions '2 x 90mm woofers, 2 x 19mm tweeters'. Can you confirm if it's 90mm or 75mm? (Omni 20 spec mentions '2 x 75mm woofer, 2 x 19mm tweeter')

Asked by: vishal
The Harman Kardon Omni 20 and Omni 20+ are two separate products, though they are very similar to each other. Those information that you have listed are both correct.
