WiFi functionality is very limited

By Tomasz

from Warszawa, Polska

Comments about Harman Kardon Adapt Wireless HD Audio Adapter:

This product has two functions - Bluetooth streaming and WiFi streaming. WiFi streaming is useless for me. I cannot connect to the device with my favourite audio software.


Great sound, but to what use.

Bought an Omni 20 2 years ago, fell for the great sound and unfortunaly did not check the software first, been waiting for an improvement ever since but now its time to abendon the ship, still no dlna support, still no Spotify, messy app that destroys the whole experience.

Good sound quality, Bad system.

By Champ114

Comments about Harman Kardon Adapt Wireless HD Audio Adapter:

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.


Limited solution to stream existing equipment

By Gogo

from Royal Oak, MI

Comments about Harman Kardon Adapt Wireless HD Audio Adapter:

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.

horrible app, poor music service choices

By scffvariable

from St Cloud, MN, United States

Comments about Harman Kardon Adapt Wireless HD Audio Adapter:

Just bought today and returning it tomorrow. App is extremely clunky and outdated. No pandora, I heart radio, etc. Also it will not stream from a music server, so all the music has to be on your device. Cant stream different music to different Adapts. Just a really poor implementation. If I could give it zero starts I would. I was trying to find a lower cost solution then the Sonos, but I am going to just bite the bullet and spend the money.


Not perfect but not as bad as some say

By MattFromReston

Comments about Harman Kardon Adapt Wireless HD Audio Adapter:

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.

adapt harman kardon. sorry but

By Miguel

from México

Comments about Harman Kardon Adapt Wireless HD Audio Adapter:

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.
