Rated 3 out of 5 by from Bonnes enceintes mais appli brouillon J'ai acheté ces enceintes en Novembre (2x Omni20). J'ai été surpris par la qualité sonore des enceintes cependant l'application mobile ne sert à rien ! Après avoir péniblement mis les enceintes sur le Wifi, il est impossible d'utiliser Spotify, que faire ? Changer de compte pour espérer écouter Spotify avec la qualité Wifi ? En attendant, j'ai écoute via bluetooth avec la rediffusion de la première enceinte vers la deuxième, avec beaucoup de coupure.. La synchro coupe trop souvent. J'attends vraiment une vraie mise à jour de l'application avec du Spotify et des vrais options, pas un "+" qui laisse suggérer que rien est fini.

Rated 1 out of 5 by from Application navrante J'ai acheté plein d'enthousiasme une paire d'enceintes omni 20. L'installation s'est bien passée et les deux enceintes couplées sont liées à la pièce nommée "salon". Sauf que sur mon téléphone huawei p9, les pièces créées disparaissent et toute la configuration doit être reprise. De plus seul le Wi-Fi 2,4 Ghz est reconnu. J'ai installé l'appli HK Controller sur une vieille tablette. Là, ça a fonctionné 2 mois sur deezer. Mais depuis ce jour, 25/02, l'appli plante sans raison. Bref, enceintes inutilisables en raison d'une appli très mal conçue et sans doute pas finie. 600 € la paire. Je vous laisse juges. Déconcertant et déconseillé évidemment

Rated 2 out of 5 by from Son de bonne qualité Achat de Noël 2015, la documentation fournie est quasi inexistante. Il faut aller chercher le mode d'emploi sur le net. l'application Harman Kardon Controller est très très limitée, vous n'avez accès qu'au musique que vous avez sur votre téléphone, tablette, vous pouvez écouter de la musique via le net mais vous n'avez que très de choix et sauf MixRadio, tout est payant. La Synchro entre téléphone et Omni 20 est particulièrement pénible. Bref, un saut de très bonne qualité, mais une utilisation loin d'être aussi simple que ce que l'on peut lire et c'est bien dommage. Je pense qu'il vaut mieux attendre que Harman Kardon règle ces problèmes avant de faire l'achat

Rated 5 out of 5 by from Great Sound! Just recently purchased the Harman Omni 20 for our home. There are several ways to connect but I connected via bluetooth. I tried connecting from my Macbook and Samsung phone. It has a nice full sound that carries throughout the whole room which was nice since we have an open floor plan. The quality of the sound does not change even when you increase the volume. The only thing I did notice was when I connected to the laptop, there was some static initially (for a split second) and then the sound is clear. Note: The description says it's wireless but you actually need to plug in. There is no battery option.

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 Outstanding quality This is my second Omni 20. For the size of my 60W HK speaker it is the best sound so far. No distortion what so ever. Cristal clear sound. Fast connectivity. Easy to use. The app is also very good. Will definitely purchase more HK products. Also strongly recommend this speaker.

Rated 5 out of 5 by from Omni 20 I had been looking at this speaker for awhile and I'm glad that I waited because I caught the Xmas sale. The omni 20 puts all other bluetooth to bed!

Rated 5 out of 5 by from Amazing Sound out of a small, smart device I have tried out so many little speakers and every time the sound is disappointingly thin without enough bass. With the omni 20's I finally found what i was looking for. Great balanced sound, clear with fantastic bass. You would think the music is coming out of a much bigger speaker set. I love the convenience of playing it from my computer or iPhone through bluetooth. Once you set it up it will go to sleep after you stop playing music and will automatically reconnect once you start again. No need to press any buttons. Highly recommended.

Hi. Recently bought an omni 20+. I'm having trouble when I'm casting from both Deezer and TuneIn. It's stuttering. Tried both Wi-Fi and hardwire. Really annoying, please help.

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.

Is there a way to lock the speaker from allowing other people to connect through Bluetooth?

Asked by: Steve8
One way of locking the speaker is to have your devices connected to it at all times so other people won't have a chance to connect and play your HK Omni 20.

I have 2 x Omni 20, and they have both started distorting and buzzing. Both do the same thing, so it looks like a software issue. I have hard reset both, and this works for a short while, but after some use both speakers buzz again. Please help.

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!

L.s. Ben inmiddels in het bezit van twee (stereo-paar) speakers Omni 20+.. Werken op WiFi prima ! Ik vraag mij alleen af dienen de beide speakers ALTIJD aan het lichtnet (stroom) verbonden te zijn ? Graag een reactie, bij voorbaat dank.

Asked by: 6SoundLover12
Bedankt voor uw vraag. De Harman Kardon Omni 50+ is de enige van de Omni reeks die een ingebouwde accu heeft om de speaker draadloos en niet aan de stroom verbonden te gebruiken. De rest van de Omni modellen zal inderdaad aan de stroomvoorziening gehouden moeten worden. Indien u nog verdere ondersteuning wenst, gelieve dan het Harman Customer Support team te contacteren per telefoon, e-mail of chat voor directe hulp. Zie https://www.harmanaudio.nl/support-contact.html voor meer informatie. Dank u.

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.
