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 5 Bluetooth Wireless Speaker stands out for delivering impressive sound quality with its 50W total system power and a frequency response range of 50Hz – 20kHz. This ensures crisp, clear audio that can fill a room, making it a great choice for music enthusiasts looking to enhance their listening experience.

The speaker also allows wireless streaming via Bluetooth 4.2 and supports connectivity for up to two smart devices, which adds versatility for multiple users or devices. Moreover, you can pair it with another Onyx Studio 5 speaker for an elevated audio experience, which is a great feature for those looking to expand their sound setup. The rechargeable battery offers up to 8 hours of playtime, making it suitable for extended use without needing frequent recharges.

Its design is both elegant and functional, featuring a round silhouette, premium fabric cover, and an integrated aluminum carrying handle that aids in portability despite its 6.6-pound weight. The speaker takes up to 8 hours to fully charge, which might be inconvenient for users who need a quick turnaround. Additionally, it is not waterproof, limiting its use in outdoor or wet environments. The floor-standing mounting type might not be ideal for users looking for more compact or wall-mounted options. The lack of an integrated MP3 player may also be a drawback for some users. Despite these minor shortcomings, the Harman Kardon Onyx Studio 5 remains a strong contender in the portable Bluetooth speaker market, especially for those prioritizing sound quality and design.
