Adapt is rated 2.0 out of 5 by 10.
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.

Rated 3 out of 5 by from Good individual components, poor system I bought an Adapt, an Omni 10 and 20 to try the system out. The conclusion so far is that the sound quality from the 10 is great, 20 slightly little less so, and that the Adapt doesn't integrate well in the setup. The Omni 20 plays a bit more undetailed and my feeling is that the 10 actually plays the lower frequency better. Both play however well and the design of especially the 10 is great. The HK Controller app is a poor experience, limited support for music services - Deezer is the only one currently - and linking the units together doesn't work if you stream the music from a phone to one of the units using Bluetooth. Here there must be improvements made; added music services (Spotify, Groovshark, Google Play Music,...), added functionality (possibility to play music stored on a NAS for example) and improved stability. I have used the HK controller on an Android device (Sony Xperia Z3).

Rated 2 out of 5 by from Drops connection, limited connectivity to reciever I have been using the Adapt and an Omni 10 pair for about a week now. The setup was fairly easy but took a couple of tries to take. I can get the bluetooth function to work with the Omni 10s, sometimes, and stream music very slowly, but the adapt (wired to an input jack on a receiver) does not seem to work under bluetooth. When streaming through the Adapt, it requires excessive volume control on the receiver to get a tolerable volume output. For the money, and HK reputation, there should be a higher fidelity option to connect the Adapt to a receiver (HDMI, optical). I can get them all working together with the app but it is very limited in function and drops connection with frustrating regularity. This droppage is in the same area I have been using both wifi and bluetooth with uninterrupted reliability on other devices and apps. Reading the product promo info, one might think that you can stream anything to this system. So far, not so much. With the app, streaming selection is slim and as far as I have been able to determine, 3rd party apps are only streamable through the poor bluetooth performance. The Omni 10 sound is good but my frustration with this inflexible system spoils my experience.

Rated 1 out of 5 by from Bad device with limited usage example: cannot play TV sound on two twin omni 10s

Rated 1 out of 5 by from Good sound quality, Bad system. I bought two of OMNI 10 and two of OMNI 20 to use in my cafe. OMIN will give you a quality of sound for both 10 & 20. However, it's so annoying that all speakers always loss their signal and you will find difficulty to reconnect it again and It happened everyday !!!! 4-5 times a day, and this is in a cafe with customers. Sometimes 1 speaker disappear somethings 2 speakers disappear. OMG !!! I'm so sick of this. Application also not support Apple Music. If company still cannot fix the issue, don't buy it.

Rated 1 out of 5 by from adapt harman kardon. sorry but I am not use to write reviews but you must think about this before buying an adapt. The bluetooth on a 8 mt. range directly no obstructuction, has a lot of disconnection. WIFI works fine but. There is not compatibility with my mac, Spotify, air drop or apple music. I am disappointed, not only for the deficient bluetooth. But the software compatibility. I hope harman (witch I own a beautiful AVR receiver) will consider a serious software actualization for wifi use. (add mac availability, not only tablet or phone) I would not recommend this product until software actualization . sorry.

can I use this device to connect 2 HK Aura together? If I Purchase Sabre sb35 and sub,and run it together with omni 10/20,do i'll get surround sound effect when watch movies?If can't,which speaker that you recommend for the best home theater and music?thx

Asked by: indra
The OMNI system, which includes the ADAPT, does not produce surround sound when connected at the same time. If you are looking to have surround home theater system, i would highly suggest that you invest in an AVR system, either 5.1, 7.1 or 7.2 system, that way you can enjoy surround audio for movies, etc...

Dear HK I have an old Go+Play (ipod dock on top version) and i luv it, can i use an ADAPT to wirelessly/BT stream to it without having to have an ipod/iphn physically docked on to it?? Thanks.

Asked by: kanchiwij
The ADAPT can be connected to the GO+PLAY via the 3.5 AUX input. You can then connect any Bluetooth/WiFi capable device as long as you have the CONTROLLER App installed on those devices.

So according to answer, it only works for omnis. But adapt says that you can integrate existing speakers with they, so isn't possible connect a onyx studio 2 with other omnis? Thanks

Asked by: Juan
Hello, Thank you for the inquiry. No. The Omni speaker line cannot be connected with the Onyx Studio speaker line. The Adapt can be used as a bluetooth adapter utilizing the auxiliary connections. The Omni and Onyx Studio 2 both have bluetooth. Best Regards.
