Harman Kardon’s Luna 2 aims to elevate the portable Bluetooth speaker segment with a sleek design, ambient lighting, and innovative connectivity options, blending style with articulate sound.
Harman Kardon’s Luna 2 is an attempt to make a familiar product category feel more considered. In What Hi-Fi?’s review, the speaker is presented as a portable Bluetooth model that pairs a compact form with ambient lighting, while Harman Kardon’s own specifications list 40W of power, Bluetooth 5.4, IP67 protection and a battery rated at up to 12 hours. The company also says the speaker supports Auracast, AirTouch stereo pairing and customisation through its One app.
Design is a major part of the appeal. The Luna 2 arrives in Classic Black, Warm Sand and Ice Mint, and its pill-shaped body is finished with anodised aluminium grilles and a sloped rubber shell that makes it easy to carry. What Hi-Fi? found the lighting ring around the base to be restrained rather than flashy, and Harman Kardon positions it as part of the product’s identity rather than a gimmick. The side-mounted USB-C port is also a practical touch, especially when the speaker is used close to a wall.
The feature set is broad for a speaker of this size. Harman Kardon says the light ring can be adjusted through the app, alongside EQ settings and battery information, while the speaker can connect to two devices at once and pair with other compatible units through Auracast. The company also says the speaker uses recycled materials in part, underlining the emphasis on a more polished, lifestyle-led design. What Hi-Fi? noted that the claimed battery life held up reasonably well in use, although it is shorter than some rivals.
Sonically, the Luna 2 is strongest in the midrange. What Hi-Fi? said vocals were clear, well projected and unusually expressive for this class of speaker, with good separation and a coherent soundstage. Bass was described as tight and controlled, but treble could sound sharp at higher frequencies, and the speaker did not match the rhythmic drive or fullness of the JBL Charge 6, which the publication treated as the main benchmark in this price band. The result is a speaker that does not dominate the portable market, but does combine style, portability and articulate sound more successfully than many alternatives.
