Our Verdict
The Harman Kardon Onyx Studio 4 provides a lot more volume than almost every other lightweight Bluetooth speakers, but does so at the trouble of portability. Weighing in at 4.5 pounds and taking on a comparable amount of space as a basketball, this speaker certainly isn’t likely to accompany you on lots of adventures. What it could do is easily follow you to every room in your own home and into your backyard, providing loud and high-quality music as you go. If you are not too concerned about volume and just want a lightweight speaker for your house that sounds great, the Bose SoundLink Revolve sounds somewhat better and doesn’t cost a lot more.

Our Analysis and TEST OUTCOMES
The Harman Kardon Onyx Studio 4 just barely fits in to the lightweight Bluetooth speaker category. In comparison to other Bluetooth speakers it really is so large that it’s more suited to active the house instead of taking with you wherever you go.

Performance Comparison
The Harman Kardon Onyx Studio 4 performed well in a few of our tests, but particularly poorly inside our portability metric, producing a mediocre overall score (as you can plainly see in the table above).

In the next sections we describe the way the Onyx Studio 4 performed in every of our individual testing metrics.

Sound Quality
The Onyx Studio 4 earned a higher score of 8 inside our sound quality testing. Using its large size it had been in a position to produce, deep, resonant bass, which wasn’t quite as deep but was much clearer compared to the bass of the JBL Charge 3. It combines this bass with crisp treble and a sizable dynamic range to make a full sound with adequate depth. Occasionally the Onyx Studio 4 would lose some clarity when playing high pitched notes, something of which the Bose SoundLink Revolve was more adept.

If a speaker is large enough to cover your complete face, we think calling it lightweight may be somewhat of a stretch.

Portability
The Onyx Studio 4 was the worst scorer inside our portability testing. It earned a 2 out of 10, remote from the very best score of 10. At 4.5 pounds the Onyx Studio 4 is nearly three times heavier compared to the next heaviest speaker inside our review. Additionally it is quite large (it really is essentially a flying saucer with an 11-inch diameter) and either won’t easily fit into or will hog all of the space in virtually any backpack or bag. We’d be hard-pressed to think about a time we’d bring this speaker further afield compared to the backyard patio. It could make it on an automobile camping trip, but with just 4.5 hours of battery life, it will not make it through lots of campfires.

The Studio 4 includes a carrying handle, which is convenient for moving it throughout the house, but you will most likely not want to transport it much beyond that.

Volume
The Onyx Studio 4 was among the loudest speakers inside our testing, sharing the very best score of 9 out of 10 with the JBL Charge 3, putting it well prior to the low score of 4. With the ability to retain sound quality at high volumes and can fill almost all of an average sized home with sound. This is obviously the speaker we’d choose if we wished to throw a major party. However, that party would need to be at the house, because we wouldn’t want to lug the speaker around.

Battery Life
The Onyx Studio 4 lasted 10.5 hours inside our battery life testing, well longer compared to the manufacturer’s claim of 8 hours, earning it the average score of 5 out of 10. Considering that is a speaker that you might probably use in or about their home, that feels as though plenty of battery life. Additionally it is, conveniently, an excellent bit longer compared to the average backyard barbeque.

Value
You will find a huge discrepancy in the Harman Kardon Onyx Studio 4’s list price and what, during this writing, it really is selling for at online retailer sites. The list price is an impressive $450, but we often view it selling for simply a third of this price. At $450 this is a terrible value as you can get a lot more capable home stereo systems for an identical cost that are just moderately less lightweight compared to the Onyx Studio 4. Additionally, if you are searching for a lightweight speaker compared to the Harman Kardon Onyx Studio 4 is an unhealthy value at any price since it most likely won’t match together with your expectations. However, if you wish a speaker that you may move around the home and will get really loud when you wish to, and you think it is on sale, the Onyx Studio 4 is a decent value.

Conclusion
The Harman Kardon Onyx Studio 4 is lightweight only in the sense that it includes a battery and will operate with out a cord, but is most probably much larger than you would like if you’re buying a lightweight speaker. In the event that you just want a semi-portable speaker for about the house, then your Onyx Studio 4 performs quite nicely.
