Our take on the Harman Kardon Onyx

Looks and performance — that's what you get with the Harman Kardon Onyx wireless portable speaker system. The elegantly simple design features a brushed aluminum handle that pivots out to become the Onxy's stand. But it's the sound that counts, and that's where the Onyx delivers.

Harman Kardon Onyx

The brushed aluminum handle swivels to become a stand for the system.

High-performance design

The Onyx has two 3/4" tweeters for detailed highs, and two 3" woofers for clear midrange and bass. Two passive radiators help reinforce the lows — one front-firing, the other rear-firing to ensure solid bass throughout the soundstage. Harman's proprietary digital signal processing ensures accurate, lifelike reproduction of your music.

Bluetooth and Wi-Fi®

The system's built-in Bluetooth lets you wirelessly stream music from your smartphone, tablet, or any other Bluetooth-compatible portable. Whether it's stored music, music services like Pandora® or Spotify, or even video and game soundtracks — if you can hear it through your portable, you can stream it via Bluetooth to the Onyx.

The Onyx also has built-in Wi-Fi, and is DLNA-certified. So you can use your DLNA-compatible AndroidT smartphone, tablet, computer, or other component to stream music and audio to the Onyx. And if you own Apple portables, good news. That Wi-Fi connectivity also lets you use Apple AirPlay through your home network.

Apple AirPlay

Apple AirPlay gives you additional options when you use iTunes® on your computer. Just open iTunes, select the Onyx in the AirPlay menu and start streaming music to the system. Use your iPhone, iPad or iPod touch® to control the iTunes menu on your computer. From your Apple hand-held device., you can stream stored music, video and game soundtracks, and even online music services like Pandora and Spotify.

Portable convenience

You can easily control the Onyx with its touch-sensitive controls. Or use the Harman Kardon's remote app to control the system through your Android or Apple smartphone or tablet. The Onyx's built-in rechargeable battery gives you up to 8 hours of operation. And when its AC adapter is plugged into a wall outlet, you can use the Onyx's USB charging port to keep your portable powered up.

Great Sounds

M Waller from Shaker Heights, Ohio on 10/22/2014

Let me be honest, I've always been a Bose man, However, I have been looking for a speaker that sounds and looks good.I found what I as looking for in the ONYX studio speaker. My only let down is that I own a IPOD Classic with over 25,000 songs on it, which can not be played on this system (not bluetooth).

Pros: Excellent sound, great looks

Cons: if your system is not bluetooth, you are out of luck. I gave your system a 4+ not a 5 for this reason. I'm not unhappy enough to return the system, I 'll just listen more to Pandora.

Bang and boom

George from Chicago hieghts on 10/21/2014

Speaker fill the room and the clarity is awesome. The sound is not aggressive . You can feel the power though. My wife brought it home and I was like really. Then I turned it on and I was REALLY!!!!

Pros: Must buy, long battery

Cons: You have to press the buttons a little hard to operate

Better then Sonos

Kyle Tinnin from Gilbert on 7/23/2014

I Love my Onyx it has the best sound quality. It has a super crisp sound and great bass. I also have a sonos and the Onyx out preforms the sonos in every way. I use my onyx every single day. Its so nice just to come home and turn on your blue tooth and you are playing music instantly.

Pros: Great Bass Crisp sound Easy set up small Good look to it

Cons: No cons

Lots of sound in a small good looking speaker

Anonymous from Fairfax, VA on 4/14/2014

Crutchfield Customer Review (What's this?)

The sounds that this little speaker can produce is impressive. It is enough to bring an outdoor party to life without the hassle of wires. The setup is easy and well explained. Wifi/Bluetooth sometimes gets interrupted but it is 100ft from the router. Still my other device operate fine at that location so I would have liked a beefier wireless capability. Look is awesome, classy, refined and the handle serves its purpose while contributing to the look. Very good quality and you can feel it. Averall I would recommend it, just be aware that you need a good Wifi signal.

Pros: Look, Quality, Sound, Power, Portability

Cons: Wifi signal needs to be strong to avoid interruptions

Cool structure

BJo from Philadephia, PA on 3/27/2014

I love the structure. Looks cool. Fills up a whole room and has nice clarity in the sound. I put it in the corner of a room and increased the vol.....nice sound effects.

Pros: Sound is uniformly spread out.

This allows you to stream stored music and music apps from your Bluetooth-enabled device (such as your Apple iPod/iPhone/iPad, Android smartphone/table, or computer/laptop) to the Onyx speaker system. You will continue to navigate your music and view song/artist information from your Bluetooth-enabled device.

  • SSP + NFC Pairing: With Secure Simple Pairing (SSP), you can easily pair a Bluetooth enabled phone to the H/K Onyx without having to enter pin codes or go through complicated settings. Android (OS 4.0+) smartphones that have Near Field Communication (NFC) pair simply by touching the Android device's NFC tag to the speaker system's NFC tag. For older Android smartphones with OS 4.0 or lower, download the NFC Easy Connect app from Google Play to use the head unit's NFC pairing function. Once paired, the Onyx will automatically re-connect with your device when in wireless range (up to 33').
Note: Due to the differences in Bluetooth technology, some Bluetooth enabled devices may be incompatible, function improperly, or may not support all features when used with the H/K Onyx.

By downloading Apple's free Remote App onto your iPod touch, iPhone, or iPad you don't even need to be in the same room as the Onyx or your computer to play, pause, skip, and stop the songs in your iTunes music library. To use the AirPlay feature you need a Mac or Windows-based PC running iTunes (10.1 or later) connected to your wireless home network. Your iPod touch, iPhone, and iPad must have iOS 4.3 or later installed and connected to the same wireless home network.

This means it's easier for you to access and enjoy digital music stored on your Windows PC, DLNA server, or DLNA-compliant Android device. You'll be able to wirelessly stream your stored music library on your compatible DLNA device to the Onyx speaker. The Onyx supports playback of a variety of music files via DLNA.

Aux Input: In addition to wireless connectivity, the H/K Onyx is fitted with a 3.5mm auxiliary input for connection of almost any portable audio player with a headphone output.

USB Charging Port: The Harman Kardon Onyx is capable of recharging the battery of your mobile device from the speaker's built-in USB (type-A) port. Now you don't need to carry an extra charger to keep your devices powered up. This USB port does not support audio playback.
