The Harman Kardon Go + Play 3 is a portable Bluetooth speaker known for its superior sound performance due to its three-way speaker design. It features a 5” subwoofer for deep bass, dual tweeters, mid-range drivers, and a front-mounted passive radiator for punchy sound. This speaker is ideal for those seeking high-quality audio with detailed vocals and instruments. In terms of power output, it boasts an impressive 160 watts, ensuring robust performance suitable for various environments.

The built-in battery offers up to 8 hours of playtime, making it reasonably portable for home use. The design stands out with a tempered glass-top touch panel, high-quality aluminum handle, and eye-catching grille fabric, combining elegance with practicality. However, the weight of 10.4 pounds may limit its portability compared to lighter alternatives. Additionally, it is not water-resistant, which could be a drawback for outdoor use. Durability is ensured with premium materials, although it’s best suited for indoor environments given the lack of water resistance.

The Harman Kardon Go + Play 3 is perfect for those who prioritize sound quality and aesthetics, with a few limitations in portability and outdoor suitability.

The Harman Kardon Onyx Studio 8 is a stylish Bluetooth speaker designed for those who want rich, room-filling sound with the convenience of portability. Thanks to Harman Kardon's advanced acoustic engineering and self-tuning feature, it automatically adjusts the audio to suit the space, offering clear and balanced sound whether you're playing music or taking calls. With a power output of 50 watts, it delivers loud and dynamic audio that can fill a medium-sized room comfortably. You can connect two devices simultaneously, making it easy to share playlists. The built-in dual microphone provides clear hands-free call quality from across the room.

Portability is a strong point here: the speaker weighs around 7.8 pounds and has a sleek aluminum handle that doubles as a base, so moving it around your home is hassle-free. Battery life reaches up to 8 hours, and it takes about 5 hours to fully recharge, which suits casual, day-long listening but might fall short for extended outdoor use. The design is elegant and modern, using premium and eco-friendly materials, which adds to its appeal. However, it is not waterproof, so it's best kept away from water or heavy moisture.

The speaker scores well in sound quality and build, though the lack of waterproofing and moderate battery runtime might limit outdoor or rugged use. This speaker suits anyone wanting a powerful yet portable indoor speaker with excellent sound clarity and a stylish look.

The Harman Kardon Onyx Studio 6 is a stylish portable Bluetooth speaker that stands out with its impressive sound quality. With a stereo audio output and a maximum power of 20 watts, it delivers a rich listening experience. The speaker has a beautiful design, featuring aluminum accents and a compact form factor, making it a great addition to any room or outdoor gathering. Its waterproof feature also adds to its versatility, allowing you to use it near water without worries.

However, there are a few drawbacks to consider. While its battery life of around 8 hours is decent for casual use, it might not be sufficient for longer events or trips without access to charging. Additionally, the speaker weighs 8.75 pounds, which could make it a bit cumbersome to carry around compared to other lighter portable options. The Bluetooth range is limited to about 10 meters, which is standard but might restrict your mobility if you plan to move far from your device.

In terms of connectivity, it supports Bluetooth, which is convenient for pairing with smartphones and tablets, but lacks other options like auxiliary inputs or USB ports for wired connections. This may limit its functionality for users who prefer wired audio or want to connect multiple devices easily.
