10 Best Harman Kardon Speakers 2025 in the United States

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 HK SoundSticks 4-2.1 Bluetooth Speaker System stands out with its unique and iconic design that is sure to catch the eye of anyone looking for a stylish audio solution. One of its biggest strengths is the extraordinary sound quality, offering rich bass thanks to the powered subwoofer, which makes it a great choice for music lovers who appreciate depth and clarity in their audio experience. With a total power output of 140 Watts, it delivers impressive sound performance suitable for various settings, from casual listening to lively gatherings.

In terms of connectivity, it supports both wired and wireless options, allowing for convenient Bluetooth streaming. This flexibility makes it easy to connect your devices without the hassle of tangled wires, appealing to users who appreciate modern technology. However, it is worth noting that, while the design is aesthetically pleasing, it is primarily a tabletop mount, which may limit where you can place it compared to more versatile, portable options.

When considering durability, the materials used in the design appear sturdy, but like any speaker with such a unique shape, care should be taken to avoid accidental damage. Portability is another area where this speaker system might not excel, as it is designed more for stationary use rather than being easily moved around. The Harman Kardon HK SoundSticks 4-2.1 is an excellent choice for those prioritizing sound quality and design aesthetics in a home or office setting, but may not suit users looking for a portable audio solution. If you're after a speaker that combines style with impressive audio performance, this could be a perfect match.

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.
