Harman Kardon Onyx Studio review

The Onyx Studio offers powerful portable sound that performs admirably across multiple genres, moves easily to any room, and looks damn good doing it.

Harman Kardon’s Onyx Studio offers powerful portable sound that performs admirably across multiple genres, moves easily to any room, and looks damn good doing it. It’s pretty pricey for how few features it offers, and it falls a little shy of full-on...

Harman Kardon Onyx Studio Review

The Harman Kardon Onyx Studio is a one-piece Bluetooth speaker that will please fans of bass, even if it's not particularly portable.

Harman/Kardon Onyx Studio 9: Lab Tested - RTINGS.com

The Harman/Kardon Onyx Studio 9 is good for listening to podcasts. Its virtually flat mid-range ensures voices sound true to life, and it gets loud enough to fill a medium-sized room. Since it's battery-powered and has a built-in carrying handle, it's...

Stereo playback, room correction feature, built-in carrying handle

Mediocre battery performance, forward-facing speaker means sound quality depends on your listening angle

Harman/Kardon Onyx Studio 8: Lab Tested - RTINGS.com

The Harman/Kardon Onyx Studio 8 is good for podcasts. It has a balanced, relatively flat mid-range response that's well suited for speech and vocal content so it'll bring out the detail in your favorite podcasters' voices. It's also very portable, so...

Sleek, unique and lightweight design, balanced default sound profile, stereo playback without downmixing to mono, room correction feature

Directivity isn't the best, poor battery life performance

Harman/Kardon Onyx Studio 6: Lab Tested - RTINGS.com

The Harman/Kardon Onyx Studio 6 is alright for music. It has a very balanced, neutral sound profile that makes it suitable for listening to lots of different music genres. However, like many smaller speakers, it struggles to reproduce a thumpy, punchy...

Decent frequency response accuracy, supports multi-device pairing

Lacks low-bass, downmixes stereo content into mono

Harman Kardon Onyx Studio Review

Harman Kardon, it's a name that both hardcore audiophiles and general consumers are familiar with. Many of us know them simply for their home and car audio equipment, but they have presence in nearly every audio spectrum – including mobile as well....

Impressive audio quality ; Sturdy construction

Extremely expensive at $400 ; Lacks any secondary features ; Too bulky in size to be deemed “portable

Even with its top-notch audio quality and pleasant looking modern design, it’s extremely difficult to overlook the speaker’s $400 cost, which is undoubtedly pricey amongst other things. For the price and all, you’re probably better off investing in an...

Harman Kardon Onyx Studio 9 Review

Punchy audio, sculptural design, and robust battery life make this compact, portable Bluetooth speaker a bona fide winner

Stylish design with excellent portability ; Multipoint pairing and USB-C charging ; 8-hour battery life

No Weatherproofing so not really suitable for beach or poolside ; Lacks Wi-Fi and smart features ; Suffers from midrange recess

Punchy audio, sculptural design, and robust battery life make this compact, portable Bluetooth speaker a bona fide winner. Sonically, it’s as clear as a bell and has bass to spare, just don’t take it out in the rain…
