Adapt is rated 2.3 out of 5 by 15.
Rated 5 out of 5 by from Easy to setup, works well! My old-school NAD and Jura setup is now belting out sounds streamed from my iPhone. Great sound, very pleased. I was nervous after some reviews of hard to setup, I simply installed the app, plugged it into the aux on the amp and power, hit the button, and it worked.

Rated 4 out of 5 by from Really Bad instructions The instructions that come with the device are truly awful. I only got it working by looking at video's on Utube. Now working its fine.

Rated 4 out of 5 by from Not perfect but not as bad as some say My setup: Yamaha receiver, Omni 20 and Adapt. This is an early review having only received the Omni products today. I am giving it four stars because I could not do 3.5 and felt the other criticism a bit harsh and wanted to balance things a little. Also, the Omni20 does sound really good - way better than most other Bluetooth speakers by far. For me, a three star product needs to meet certain criteria: advertised functionality works, is reasonably intuitive to use and I can understand the philosophy behind the design approach. The Omni and Controller app meet all these criteria to various degrees and in addition has some other compelling good points. When I bought this setup, I was looking for three things: 1) Cheaper than Sonos 2) Be able to stream music from CD player out to all other Omni products 3) Be able to link one Omni product to iPad Bluetooth and then have it restreamed everywhere. I have successfully tested all three of these and given the complexity involved with doing this I am actually quite pleased. The Party Mode and Link is really cool. I love the volume controller that lets you tweak the volumes in various rooms on a single dashboard. Let me give the bad points now: -The controller app needs better instructions on usability. Any idea what the home icon does? I have no clue and can't find it documented anywhere. I am partially blind in one eye so maybe it's fine print? :) -Searching for music on your system. I have been struggling with this all night. Some songs play and others come up with a useless message saying they can not be played. -The app needs a simple mute button which can be found quickly. Some final thoughts I have are, I suggest having some patience with the app when it searches for products and is doing the background setup. HK appears to be on the right track here. Hopefully newer versions of the app will be easier to use. I am hoping to come back in a few weeks and give an even more favorable follow up review. I want this system to work. Sonos, while a good product, is ridiculously overpriced in my opinion.

Rated 3 out of 5 by from Limited solution to stream existing equipment Adapt is an inexpensive solution to add your existing stereo to streaming. Fits the bill for me to stream radio to my Omni speakers. Need to turn volume up very high when streaming to your stereo through Adapt. Hope HK upgrades this component to compete with Sonos Connect.

Rated 3 out of 5 by from It takes some fiddling I have been using Airplay for some years now and I wanted to update the system to something that would allow me to stream to multiple speakers from my mobile. I bought 3 adapt and an Omni 20, it's been almost a month and I'm still trying to figure out the sytem, I set it up and worked fine , then it started to cut off (that has been the standard) I decided to reset the whole thing last weekend and it has been working fine since. It is a shame the app is not useful since it doesn't support Pandora , Spotify or even Itunes Match or Radio and the featured radio stations I find them substandard. Something you need to keep in mind, anytime you reset your router or the system, the volume of the adapt goes all the way up so you can burn the speakers connected to it, it does not happen with the Omni 20.

Omni adapt have a &quot;audio out/ mic in&quot; connector. The &quot;audio out&quot; function is straightforward to understand and it's explained in the manual, but can I use the mic-in function? If yes, How can I use it?

Asked by: Demenx
The audio out/mic in when connected to a receiver (for example) would be used by source devices connecting Bluetooth or wireless and wireless rebroadcast from an OMNI 10/20 via the ADAPT

I have an AVR 161s and I couldn&rsquo;t manage to connect the adapt so I can play music trough wifi. I downloaded the app on the phone and manage to set up a room, but when I play music, there is no sound. Can you please explain how to connect?

Asked by: shortyfpc
Please connect the Adapt audio out to the AVR 1610s Analog 1 audio in and set the source to Analog 1. I noticed that you are in United Arab Emirates. If this doesn't help, please send an e-mail to info@harmanme.com and the Customer Service team will be more than happy to further assist you.

If i dont have wifi in my house, can i use the speakers omni 20 through wifi using the adapt hd?

Asked by: Caballerolance
The OMNI speaker and ADAPT can only communicate via a wireless&nbsp;network. Although internet access is only needed for system updates/downloads, a Wi-Fi network must be setup for adequate communication. &nbsp;&nbsp;

I have a harman kardon Onyx studio 2 can i use the adapt to link with those omni speakers? Play all together?

Asked by: Mars
Yes, this can be done. You can connect the ADAPT to your ONYX STUDIO 2 from the ADAPT&rsquo;s Audio Out port to the ONYX STUDIO 2&rsquo;s Aux Input. Do the usual set-up available in the Owner&rsquo;s Manual on setting up your OMNI/ADAPT speakers and now, the ADAPT will stream the signals that you will play through the ONYX STUDIO 2.

I am looking for a method to connect my old desk top speakers with the 3.5mm connector to my wi fi network to paly music from my PC and/or android phone. Will adapt product work?

Asked by: Brianbdub
You simply need to connect your speakers to the Audio Out port of the ADAPT located at the far left when looking at the back of the unit as shown in the Quick Start Guide and follow the set-up procedure requiring a smart device, a wireless network and the HK Controller App.
