The first thing you notice right out of the box is that the Harman Kardon Luna has a compact and elegant design that breaks away from the conventional aesthetics of other speakers on the market.

It is covered in a fabric that looks sturdy and gives it a luxurious look. On the front we find the brand’s logo, discreetly placed without taking all the attention.

The top is also a sign of its premium look as it is made of anodized aluminum. Here we find the typical buttons for power on/off, volume, music pause/play and Bluetooth activation. There is also a row of LED lights that indicate the battery status.

In addition to its sleek design, it is made from recycled materials such as 100% polyester, 85% plastic and 50% aluminum. This combination ensures both durability and environmental sustainability.

Its small size makes it easy to take with you anywhere. It is only 21 cm long, 7.8 cm wide, 8 cm high and weighs 710 grams, making it very portable and versatile.

In addition, its IP67 rating makes it resistant to water and dust, expanding its use in a variety of environments.

Connectivity and extras

The speaker is equipped with Bluetooth 5.3, which provides a fast and stable connection to other devices.

In terms of physical connections, it only has a USB port for charging. Mention that this port is only for charging the device and does not have the ability to play music. On the other hand, it does not include an auxiliary port to use it also by cable.

Battery life

Another outstanding feature is its incredible battery life. With its 4800 milliampere battery, it gets up to twelve hours of continuous playback.

This figure is officially announced by the brand, but it will depend on the volume at which you use it. Around 30 or 35% of the volume, if you can reach this figure, if you already exceed it, the battery life is lower.

Compared to other similar models, such as the JBL Charge 5, it is slightly lower, as the latter reaches up to 20 hours.

Sound quality

When choosing a portable speaker, sound quality is one of the most important aspects to consider. In our opinion, the Harman Kardon Luna performs very well in this area and stands out for its powerful and clear sound.

In terms of specifications, it has a 2-way system with two 48 x 90mm drivers and a 20mm tweeter for the highs. The power output of twenty-five watts RMS and fifteen watts RMS respectively guarantees a powerful listening experience both indoors and outdoors. The frequency response is from 60 Hz to 20 kHz.

Unlike other models, the Luna achieves a balance of bass, midrange and treble that provides a premium experience for a speaker of its size and price.

When put to the test, the Luna shows remarkable sonic coherence, with sub-bass coming through even at high volumes. The midrange and treble tones are in place and provide a balanced and enjoyable listening experience.

With a few specific examples, such as the song “Adore You” by Harry Styles, we can appreciate how the electric guitar, the subtle keyboard arrangements and the catchy bass line fill every corner of the room. Styles’ distinctive voice glides effortlessly between these elements, creating an impeccable ensemble.

Speaking of tonal color, this unit brings out both deep bass and crisp treble without sacrificing one for the other. For example, on Lady Gaga’s “Stupid Love,” the electrifying synths are reproduced with power and precision.

On the other hand, when we get to the chorus, we enjoy some exquisite shimmering in the mids and highs, where the backing vocals take on a life of their own, creating a good enveloping sensation.

If you want to double the power, you have the option of adding another speaker at the same time to achieve stereo audio.

Price and market competition

One of the things to consider when buying the Luna speaker is its price. Compared to other models on the market, such as JBL’s Charge 5, it is a bit more expensive. However, its sound quality and performance justify the price.

The Luna may be the perfect choice if you’re looking for a portable speaker that combines style and performance and don’t mind investing in a premium device.

One of its strengths is its ability to deliver immersive sound without losing subtle details and nuances. It delivers powerful bass while maintaining exquisite definition in the midrange and treble.

To sum up, the Harman Kardon Luna portable speaker is an excellent choice for those looking for sound quality and attractive design in a compact device. Despite its somewhat high price, its performance and features make it a worthwhile investment for music lovers.

Other alternatives

JBL Charge 5

While we think the Harman Kardon Luna is an excellent buy, there are other options on the market worth considering.

Perhaps the best alternative is the JBL Charge 5, which we have previously reviewed. It is a slightly larger model and shares many of the same features as the Harman Kardon.

It has a different speaker configuration with a 52 x 90 mm woofer and a 20 mm dome tweeter. This is accompanied by two passive radiators at each end. The power output is also 40W.

The main differences are that the Harman Kardon sound is a bit more refined, with better midrange and bass reproduction. It is also a bit lighter and smaller, making it more portable.

The JBL Charge 5 Series has the advantage of longer battery life and a lower price point.


Another alternative is the LG XBOOM Go XG7 that we have already seen. The big advantage of this model is that it has a price that can be under 100€ depending on the offers.

This XG7 series achieves more power and deeper bass than the Charge 5. Compared to the Harman Kardon Luna, the latter has a more balanced sound, but this LG model also sounds fantastic.

It may not look as premium and elegant as the Luna, but it does offer some lighting effects to create a more festive atmosphere and also comes with an auxiliary port.

8.9 Total Score
Harman Kardon Luna review

The sleek design and high-quality audio capabilities make this an appealing choice. Most notable is the sound quality it delivers, with crisp, clear highs and bass that has an enveloping depth without being overwhelming. It is not easy to find weaknesses, apart from the lack of an auxiliary jack, which is always useful for those who want to use it by cable, and a battery that, without being bad, is a little below some of its competitors.
