Add Bluetooth® and Wi-Fi® to your stereo

If you've got a killer home theater system that's missing wireless music streaming, there's a simple fix: the Harman Kardon Adapt. This compact device adds Bluetooth and Wi-Fi to your existing stereo or home theater setup, so you can stream music wirelessly with your smartphone or tablet. Just connect it to your receiver or amp, plug in the power cord, download the free app, and you'll open up a whole new world of music choices in your home theater.

Music throughout your home

The Adapt isn't just about adding more music to your current system. It can also link up with Harman Kardon's Omni speakers, to create a whole-home music system. Add an Omni 10 to your kitchen so you can keep listening while you grab a snack. Or play a different song in each room.

Easy wireless setup and operation

The Adapt works with your existing home Wi-Fi network, so it's easy to set up in just a few minutes. Once you're connected, you can stream music wirelessly using your smartphone or tablet. Send tunes to your stereo system and to Harman Kardon Omni speakers throughout your home. You can even stream 24-bit/96kHz high-resolution music for better-than-CD sound.

Harman Kardon Adapt

The compact Adapt offers Bluetooth and Wi-Fi connectivity for wireless music listening.

Stream audio from any app with Bluetooth®

In addition to Wi-Fi connectivity, the Adapt offers Bluetooth, which lets you stream audio from any app on your phone or tablet. Any song you can play on your device can be played wirelessly through your stereo using this compact adapter. Have apps for Spotify®, Pandora®, Google Play, and other music services? Stream them all via Bluetooth, with no restrictions. You can even stream from YouTube™ or audio from a video game — there are practically no limits. You can also send that Bluetooth stream to other Harman Kardon Omni speakers and components.

Easy control with your phone or tablet

Your smartphone or tablet isn't just your music source — it's also the remote. Download the free Harman Kardon Controller app to your Apple or Android device. Then, you can choose songs stored on your device, control music playback and volume, and group compatible HK speakers and components together for playing in multiple rooms. The app's colorful, intuitive interface makes multi-room music easy and enjoyable.

Add music to another room... without touching your smartphone

On the top of the Adapt, there's a large button with a slash. That's the "Link" button, and it offers some very cool features. Let's say you're listening to music in the kitchen on an Omni 10 speaker. As you move into the living room, you want the music to follow you. Simply press the Link button on the Adapt, and your stereo system will pick up the same music stream in perfect synchronization. Press and hold the Link button to engage party mode, so the same song plays on your entire Harman Kardon system of products.

Harman Kardon Adapt

Ken from Rogers, AR on 1/29/2017

Crutchfield Customer Review (What's this?)

Wow, talk about a nightmare. I purchased this so I could set-up some external speakers from my TV. You see my 94 year old father lives with us. He has to have the TV cranked all of the way up to hear it. He doesn't want to wear headphones either so I purchased this unit with two of the Omni 10 speakers. Hooking up this thing was a nightmare (mind you I spent 10 years as a senior network engineer for an extremely large company). The documentation is a joke. When I did finally get it hooked up, it only played out one speaker. I got online with the manufacture and received a more documented instruction. I will give that a try. I am a big Pandora fan - guess what, Pandora doesn't work with HK products.

User Friendliness Needs Improvement

Richard from Altamonte Springs, Fl on 12/10/2016

Crutchfield Customer Review (What's this?)

This is a small unit which claims to allow streaming from digital device into your analog receiver and play through,the speaker. The instructions which come with the product may be the worst I have ever seen. Also, though slightly better, there is a confusing online manual. I am an engineer and I struggled with setup of this product for a good part of the night, and finall-y got it working. I still find its use less valuable than I thought since it streams only certain music sources from the web, but does that reasonably well. This is a useful project for enhancing your old receiver but needs more user friendly improvement.

Pros: Useful for streaming

Cons: Not user friendly setup

Good alternative to Sonos

MattFromReston from Reston, VA on 11/23/2015

Crutchfield Customer Review (What's this?)

I am giving this 5 stars because it is a way cheaper than Sonos for streaming music from a CD player and it works well from what I can tell. The 3.5mm jacks are OK, but I think RCA jacks would provide better connection quality? Of course this would make the unit bigger which would not be an issue for me. Also an on-off switch would be nice instead of just plugging in USB cable. The Controller app really needs work to serve up the music files intelligently. The volume and system control work well, but needs a master mute so I can grab the phone and be bothered by a yet another telemarketer.

Pros: Easy to use and set up - especially Bluetooth. Better sound quality than I expected.

Cons: Only 3.5mm jacks. I think RCA jacks would provide better connection quality? Controller app has some issues. Controller app needs master mute function.

Pros: half of it worked

Cons: app needs a lot of work

Best way to connect a receiver to wireless audio network

RandFan from New Jersey on 8/24/2015

Crutchfield Customer Review (What's this?)

I shopped around for a long time for a wireless audio solution for my home; I went with the Harman Kardon system for a few reasons, the first being sound quality and the second being the HK Adapt. In particular, the HK Adapt's price. It's much less expensive than the Sonos equivalent, like half for nearly the same functionality. I just wanted to connect my existing receiver to sync with the rest of my wireless speakers in my home to play the same music everywhere. The HK Adapt does the job beautifully and at half the price of Sonos!

Pros: Great functionality and connectivity, at half the price of the Sonos and Denon equivalent.

Cons: Application needs to be improved in the next release, it's usable, does not cut out, and is not terrible, but there is room for improvement.

Crutchfield Customer Review (What's this?)

The adapt is a must have with the omni 20 and omni 10. The adapt will is the perfect way to Ty all your audio systems to gather, stero, iPad, iPhone, etc. if you buy any omni speaker you need to buy the adapt with it. Instructions need to be a lot better writing for the average user.

Pros: N/a

Cons: N/a

Why did you buy this?

My plan is to run the output of my stereo (headphone or rca) into the input of this device. That should send my audio over the wifi network to an Omi 10 located far away. [ ashley  Oct 27, 2016 ]

You can configure up to six Harman/Kardon wireless HD components in six different rooms of your home. For more details or to discuss further please contact an Advisor directly by phone (888.955.6000) or online chat. Thanks! [ Larry  Jan 02, 2018 ]  Staff
It should be compatible with any receiver since it uses 1/4 headphone to RCA connectors. RCA connectors are universal connector types on most receivers. [ THOMAS  Oct 04, 2016 ]
The Adapt can connect to an unused auxiliary input through your RCA jacks. (This will work an any receiver/preamp) What you need is a 1/4 inch stereo jack to RCA female plug adapters like this: I would not spend big bucks on cables if you just listen to mp3s. Otherwise, cables are worth the investment. [ MATTHEW  Oct 04, 2016 ]
It should be compatible, I'm currently using it with an Onkyo receiver. It must be plugged in to an AUX INPUT, the headphone jack is an OUTPUT. [ GUILLERMO  Oct 04, 2016 ]
I use a 1/4"-to-minijack cable between my receiver (not an HK 3485, but that shouldn't make any difference) and the Adapt. [ MARK  Oct 04, 2016 ]
And its a lot cheaper than Sonos!!!!! [ MATTHEW  Oct 04, 2016 ]
Depends on your TV. If your TV has a headphone output, that's probably an 1/8 inch phono jack, and all you would need is a male-male cable to connect to the 1/8 inch phono jack input on the Adapt. If your TV has RCA jacks for the audio output, you'll need a adapter, but that's just a couple of dollars. [ Scott  Dec 28, 2015 ]
I am not an expert with surround sound. So, I am going to keep things simple and assume you have a TV on one side of the room and want to get the sound from the TV as an input into your AV receiver/amp on the other side of the room. My config is not like this, but I believe it may be possible to have two HK Adapts: one to send from the TV and one to plug into the receiver and then use the "Party mode" or "Link" feature to sync them. Based on my assumptions I can think of at least four issues you need to be aware of: 1) Your TV will need RCA jacks or a 3.5 mm composite for audio output. The Adapt only takes a 3.5mm jack as input and output. T3e folks at Crutchfield can help you figure out which cables you need. 2) The headphone jack could work as an imput, but it will be subject to volume control on your TV. This could be an issue, which leads me to.... 3) There will be a slight delay between the sound coming out of your TV and the sound coming out of your AV system. This is due to network traffic. The solution here is to not use the sound on your TV. 4) If you have other HK products or going to purchase them in the future, the party mode might well "hijack" those other devices on the fly so you may have to work with setting up zones or something. Good luck! Let us know how it turns out. [ MATTHEW  Dec 17, 2015 ]
If your TV has some audio out you need a cable that fits that output on one end and has a 3.5 mm on the other end to go in the adapt. (This isn't normal, normally you connect to an amp.) However (a) I don't recommend for video because there's a lag so that video and audio won't be in sync (b) it's not real surround sound. While you can pair speakers as L/R there's no front back and no center. [ Andrew  Dec 16, 2015 ]
If you have a two zone receiver like Yamaha R-S500 you can use the rec-out / zone 2 outputs to route the output of the receiver back through the Adapt and then into the line 3 or some other unused source.. Kludgey? For sure yes! But at least now I can broadcast and use my speakers at the same time. And when I want to just enjoy the speakers I can set the main source appropriately. [ MATTHEW  Dec 17, 2015 ]
I only have one adapt, but I have 3 speakers. I don't see why there would be a problem, streaming to 2 adapts should be similar to streaming to 2 speakers. The only problem is streaming FROM an adapt. In this case the sound coming from your stereo is out of sync with the HK speakers. Hence the adapt is only useful for broadcasting if (a) you are not also playing the sound on your stero/receiver speakers (ii) your rooms are sonically separated so you can't hear the lack of sync. Personally I never use my adapt to broadcast as a result. [ Andrew  Aug 27, 2015 ]
I forwarded your question to an Advisor and they responded with the following: The Harman Kardon device is designed to be connected to your existing stereo system, however, it will only send music to Harman Kardon Omni devices. You can use up to 6 devices: or If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Dec 21, 2014 ]  Staff
