The Harman Kardon Onyx Studio 3 can be an impressive speaker. Period. It plays down the portability of a speaker and only better acoustics that results in fun, bassy and rich audio tracks clarity. If you would like something for house gatherings or stationary in your living room, this can be a definitive choice for the occasion.

Bold and Full Audio
In the box, you’ll find the minimum essentials to begin with – a proprietary mains AC power cable, warrantee and instructions. No extra thrills here, just the Harman Kardon Onyx Studio 3 speaker.

The Harman Kardon Onyx Studio 3 builds on the success of the initial and second generation Onyx Studio. With refined features and aesthetics, it now uses Bluetooth 4.1 for dual speaker support, escalates the range to stay linked up to 30m together with your device and uses Low-Energy (LE) Bluetooth consumption to squeeze as much battery for audio.

The color of the soft-matte legs are actually constant with all of those other body and can be found in five colours: white, black, burgundy, navy and grey. The conference call button moves up to become listed on the energy, volume and Bluetooth soft-touch buttons around the perimeter. This implies a clean and stylish front, with only the mesh speaker grill and the Harman Kardon logo gracing the surface.

If you’re looking for small compact speakers, keep looking – they are in no way small at 28cm x 17cm x 26cm. However the Harman Kardon Onyx Studio 3 is lightweight ‘enough’ to transport around in a bag or about the house, because of the handle on the trunk and circular design.

The handle is quite useful and makes carrying it easy. I love to call it ‘semi-portable’ because for what it really is, you’re still getting something lightweight – not as subtle or small enough for each and every occasion. The bigger size results in immersive acoustic performance however.

Deep Bass, Rich Treble
The bigger footprint has many perks that bring the Onyx Studio 3 alive. With two large Woofers (2 x 75mm) and two Tweeters ( 2 x 20mm), the bass feels rounded and reaches deep levels without overpowering the mid and high tones. It stays fun, while keeping the bass in-check in order to benefit from the vibrance of the music. The tweeters located on either side of the logo on leading produces spacial sound to cover a broad area.

All of this results in a speaker that gives beautiful notes of sound – soothing harmonies that are calm and mellow; bright, rich vocals and modern beats that are bold and powerful.

Beautiful silver accent on the woofer back. Greatl bass production
There is little that comes even close to the Harman Kardon Onyx Studio 3 in terms of balance – some speakers have powering bass that drowns and muffles out the mids and highs. Some speakers pay close attention for accurate sound reproduction, but will come across quite mundane. The Onyx Studio 3 offers the very best of both without distortion at max volume.

I’ve played it in the garden, inside your home and out on view area – you’ll be pleased with the sound indeed. Smaller speakers can have problems with flat two-dimensional sound as a result of its size, as the Studio 3 offers ‘full’ sound because of a larger cavity.

Going Duo with Dual Speakers
I had some Harman Kardon Onyx Studio 3 speakers to essentially observe how it performs in parallel. Establishing the Dual speaker function is merely okay – it is usually quite finicky and clunky. This plays dual mono rather than stereo – it won’t replacement for your left and right stereo audio system speakers if that’s what you’re looking for. Everything you do get however are dual mono speakers that are excellent for putting in several rooms with single control on volume and music experience.

Going double brings the music two places simultaneously
After holding down the Bluetooth button until multiple beeps sound to pair, the music will play across both speakers needlessly to say. Something I didn’t expect is that as the volume can’t be managed independently (both play at the same level), there is distinctly the one which plays louder compared to the other. I’m uncertain why, but I suspect one acts as a primary unit and the other a sub-unit.

It’s not a major deal but if you’re wondering, this is why. You’ll also have to disconnect them from the other person if you wish to resume playing separately rather than think it is connecting to the other person and playing audio tracks from the other – this could be frustrating. Something like this will be handled by an iphone app to easily control that process. Stereo speakers would also be welcomed for immersive audio, But with with that said, they are functions beyond the core experience and shouldn’t detract much from the strong package on display.

Harman Kardon Onyx Studio 3 may be the One
The Harman Kardon Onyx Studio 3 battery could possibly be better. At 5 hours in low volume, it’s ok but just a little on the reduced side. Other speakers rated at a day still can deliver around 12 hours that is a significant difference. The bigger sound output and power required is a reason behind that, but also for playback at high or max volume, you are considering a brief 1-2 hours.

So, you really should think when you choose to really push it while from the road – you could have no battery by enough time you arrive. The speakers plugged-in output 60W of power. When running on battery, channel power is halved to 30W, with the quantity levels down by the same amount. That is normal with other speakers, but something to notice why it may well not go as loud when off-mains.
