Comparison between Harman Kardon Onyx Studio 4 and 5
About the Design of Both Speakers
Both the Harman Kardon Onyx Studio 4 and 5 feature unique designs, but there are some distinct differences between them.
The Harman Kardon Onyx Studio 4 sports a 'flying saucer' design with two cylindrical legs at the back and a front wrapped in a layer of soft woven fabric. Every detail is designed to be minimalist yet incredibly sophisticated. The back of the speaker is crafted from premium hard plastic, ensuring durability. The front and back are connected by a soft silicone strip, with control buttons placed on top. This design makes adjusting settings much easier.

Meanwhile, the Harman Kardon Onyx Studio 5 boasts a different shape with a sturdy reinforced base and a narrowed top. The speaker features an aluminum handle on top and a control panel with various function buttons below. Its rear layout includes additional AUX, power, and micro USB ports. The entire Onyx Studio 5 speaker is wrapped in premium fabric. Additionally, the speaker has a redesigned handle for a firmer grip. The Onyx Studio 5 also eliminates the cylindrical leg details on the back for a more seamless block design.
About the Sound Quality of Studio 4 and 5
Both the Harman Kardon Onyx Studio 4 and 5 deliver excellent sound quality, with the ability to reproduce detailed and clear audio. However, there is a significant difference in their sound quality due to their use of different drivers.
On the Onyx Studio 4 speaker, the bass sound is delivered deep and powerful, making it the most prominent range. However, the mid and high ranges only reach a decent level. The rear subwoofer produces rhythmic beats, creating an enjoyable effect. This product is ideal for playing strong rock or EDM music.

In contrast to the Onyx Studio 4, the Onyx Studio 5 offers more balanced and refined sound. The bass is moderate, not too deep, supporting the mid and high ranges. The product is suitable for various music genres, especially gentle ballads and songs focusing on vocals.
Other Differences in Features between the 2 Speakers

The Harman Kardon Onyx Studio 4 is equipped with HK Connect+ technology, allowing connection to multiple speakers, forming either a stereo sound system or surround sound. In contrast, the Onyx Studio 5 eliminates this feature and only connects via Bluetooth.
One area where the Onyx Studio 4 excels over the Onyx Studio 5 is in the speakerphone feature. The Onyx Studio 4 is equipped with noise-canceling microphones, enabling easy call handling with just a touch of a button. In contrast, the Onyx Studio 5 limits this feature.
