harman/kardon Onyx Studio 4 – Portable Speaker, Wireless, Bluetooth 100 Black

Product Information

Step 1 – Turn on the first speaker, initiate pairing (press the Bluetooth button) and pair it with your phone. You can stream your music to the first speaker now. Onyx Studio 4 can be loud but it’s not louder than some competitors within the same price range (like UE MEGABOOM or Marshal Kilburn). The Harman Kardon Onyx Studio 4 just barely fits into the portable Bluetooth speaker category. Compared to other Bluetooth speakers it is so large that it is more suited to moving around the house rather than taking with you wherever you go. Performance Comparison We can’t complain about the Bluetooth connection and sound quality (sound quality will be discussed in the next section).

The app is poorly rated on Google Play and App Store and users don’t really like it. It’s too basic. You can (have to) use it to select the stereo or party mode or to program the handsfree/call button. You can’t play with the sound signature and adjust the EQ settings through the app.The Harman Kardon Onyx Studio 4 performed well in some of our tests, but particularly poorly in our portability metric, resulting in a mediocre overall score (as you can see in the table above). Step 3 – Press the Connect+ button on the first speaker and then press the same button on the other speaker. Step 6 – Open the app and select stereo mode. The speakers should start playing in stereo mode (left and right channels).

If you need something really cheap that looks similar to Onyx Studio 4, iClever BoostSound might be the best thing for you. You should be aware that iClever BoostSound could never deliver the same sound quality but it’s actually not that bad. iClever looks and feels cheaper (which is not a surprise). The bass is more boosted than on Onyx Studio 4 and. iClever’s playtime is slightly longer (12 hours compared to 7 hours). iClever features micro SD card slot while Studio 4 doesn’t. On the other hand, Studio 4 comes with the app and can be paired with up to 100 Onyx Studio 4 speakers. They both have built-in mics.The built-in mic works flawlessly even if there’s too much noise around you. Kudos to Harman Kardon for that. Omni 10 is another example of Harman Kardon’s recognizable design. Omni 10 is as stylish as Onyx Studio 4 but it’s inferior in all the other aspects. The sound is rich and balanced, the bass is maybe even punchier than on Studio 4 but the overall sound quality of Onyx Studio 4 is better. Studio 4 features more powerful battery (longer playtime), it comes with the app, it has a greater Bluetooth range and more stable connection, and it can be paired with up to 100 other Studio 4 speakers. Omni 10 is significantly cheaper. The grille is removable (but it doesn’t come off easily). You can use the speaker with or without the grille, depending on your taste. The grille has a protective purpose so you might want to leave it on, especially if you are going to use the speaker outdoors.

Unfortunately, it’s not all that great. Most of our complaints are related to battery durability (this beautiful speaker needs some stronger battery) and build quality. This speaker is made of premium materials and looks/feels expensive but it’s not rugged enough and it’s not the best choice if you need an outdoor Bluetooth speaker. You can use it outdoors since it’s portable/battery-operated but it’s not rugged enough. If you need something rugged and waterproof , you should look elsewhere. Harman Kardon Onyx Studio 4 comes in a premium-looking box along with a charging adapter (2 wall adapters for EU and US market), user manual, and 1-year warranty. Hard carrying case is not included and you have to buy it separately. The speaker has one 3.5mm input but the audio cable is also not included. Specs Harman Kardon Onyx Studio 4 Specifications

The speaker has a built-in microphone (speakerphone feature) with some nice software add-ons (voicelogic + echo/noise canceling). On the rear panel, you will see the carrying handle at the top, the bass reflex port in the middle, and input ports at the bottom. There are also two undetachable feet that provide stability.

Mids are dynamic and all the voices are perfectly clear. Lower mid frequencies don’t get overpowered by the bass until you increase the volume above 80%. The distortion becomes noticeable at 90% volume but it’s not too distracting. The bass response is impressive for the speaker of this size. The low frequencies are present and punchy even at low volumes (maybe even slightly boosted). In the following sections we describe how the Onyx Studio 4 performed in all of our individual testing metrics. Sound Quality

The whole front panel is covered with a fabric grille that protects the drivers. There’s a simple harman/kardon logo on the grille. Since then, I have become much more careful around radios, boomboxes, and other audio devices (at least, I like to think so) but I have never lost the passion for audio equipment. Throughout 20 years of my professional career, I’ve been working for various audio equipment manufacturers and even started building speakers on my own in my little workshop. The battery is not that small (3,000mAh) but there are four drivers inside (+ passive bass radiator) so the playtime is not really great. Harman Kardon claims that you can get 8 hours of playtime but you can actually get less than 7 at 50% volume (less than 4 hours at 100%). This great sounding speaker needs some larger battery.
