Analyzing Competitors

This model faces tough competition from other portable Bluetooth speakers. Let’s see how it measures against two of its most formidable competitors: the Onyx Studio 5 and the JBL Boombox 2.

The Onyx Studio 5 from Harman Kardon

Several of the same design and feature choices were made across the Onyx Studio 5 and the newer Onyx Studio 6. For example, both speakers have a waterproof rating of IPX7, are compatible with Bluetooth 5.0, and you can use it in wireless stereo pairing.

In contrast to its predecessor, the Onyx Studio 5, the Onyx Studio 6 boasts several improvements. Battery life is improved with the Onyx Studio 6, with up to 8 hours оf playback time instead of 5 hours in the Onyx Studio 5. Compared to its predecessor, the Onyx Studio 5, the newer Onyx Studio 6 looks and feels more high-end.

A further well-known portable Bluetooth speaker that rivals the Onyx Studio 6 is JBL’s Boombox 2. The Boombox 2 is bulkier than Harman Kardon’s model, measuring 19.1 inches in height and weighing 13 pounds. However, the Boombox 2’s 80 watts of output and 50 Hz to 20-kilohertz frequency responsiveness make up for this.

The Boombox 2 can play music for up to 24 hours on a single charge, significantly longer than the Harman Kardon’s model 12 hours. Although Harman Kardon’s model is waterproof, the Boombox 2 is not.

The JBL Boombox 2 has better battery life and sound quality, but the Harman Kardon model is more portable and waterproof. So, Harman Kardon’s model is a strong contender for portable Bluetooth speakers because of its stylish design, convenient features, and well-balanced audio.


The Harman Kardon Onyx Studio 6 is a fantastic Bluetooth speaker because of its clear and dynamic sound, stylish appearance, and extensive functionality. Its Bluetooth 5.0 connectivity and wireless stereo pairing function make it simple and adaptable, while its 50-watt amplifier and 4.7-inch woofer produce powerful and clear music.

This piece is an excellent option for individuals searching for a lightweight and feature-rich Bluetooth speaker due tо its rechargeable battery, USB charging connector, and integrated microphone.

This purchase is a good alternative for individuals who want to take their music wherever they go without sacrificing sound quality or style, despite stiff competition from other popular portable Bluetooth speakers like the JBL Boombox 2.
