Competitors Comparison

This model is not the only choice for wireless speaker systems. Bose’s SoundLink Mini II and JBL’s Charge 3 are two of the best-selling alternatives. A comparison between the Harman Kardon Onyx Studio 2 and its two main rivals is аs follows:

The Bose SoundLink Mini II is another well-liked wireless speaker system, and for a good reason: it produces high-quality music and is surprisingly portable. Sound quality is remarkable, with well-defined bass and clean highs, despite the SoundLink Mini II’s smaller size than the Harman Kardon’s model. 

So, unlike the Harman Kardon Onyx Studio 2, the SoundLink Mini II does not come with a built-in handle, which may make it less convenient to transport. Also, the SoundLink Mini II’s battery life is inferior to that of the Harman Kardon’s model, with only 10 hours of playback possible on a single charge, as opposed to the Onyx Studio 2’s 5.

The JBL Charge 3 is another well-liked wireless speaker system, and it’s well-known for its robust build and high-quality sound. The JBL Charge 3, like the Harman Kardon’s model, features a built-in handle that makes it convenient to move the speaker from one location to another or to take it with you when you leave the house. 

The Charge 3’s battery life is superior to the Harman Kardon’s model, lasting up to 20 hours on a single charge. So, the Charge 3 is less portable than the Harman Kardon model due to its greater size and weight. The Charge 3’s bass is impressive, but the mids and highs aren’t as clear as they are on the Onyx Studio 2.

Compared to its rivals, this piece stands independently because of its superior sound quality, stylish design, and integrated microphone. That means the Onyx Studio 2 is a portable and adaptable option that, while not quite as powerful as the Bose SoundLink Mini II or JBL Charge 3, nevertheless manages to outperform them.


Anyone in the market for a wireless speaker system that doesn’t sacrifice sound quality, portability, or flexibility should strongly consider the Harman Kardon Onyx Studio 2. This piece provides a remarkable listening experience that will gratify even the most critical music lover thanks to its impressive bass response, well-defined mids, and crisp highs.
