Small, elegant speaker with great sound

Full and clear sound
Elegant design
Beautiful glow
No play/pause button

The Harman Kardon Luna 2 is a compact and stylish speaker that I use at home and on the go. The built-in light gives the speaker a beautiful glow. It is a bit inconvenient that there is no play/pause button on the speaker.

Full and clear sound The speaker delivers clear and balanced sound. As a result, music sounds realistic. The speaker's volume can go very high. When I turn the volume down to two-thirds, the music already sounds powerful throughout my entire living room. Even at high volume, the sound remains full. I personally love strong bass tones. In the Harman Kardon One app, I turn up the bass using the equalizer. This allows me to enjoy rap and house music even more. Higher tones, such as instruments, sound clear. For instance, I can clearly hear the trumpet in the background of a song. With classical music from an orchestra, I can hear the different parts well, but thanks to the balanced sound, it sounds like a beautiful whole.

Elegant design The speaker has an elegant, slim design. The matte finish on the front and back gives it a luxurious look. The matte material in the middle feels soft to the touch. The control buttons are located on this section. They feel nice to the touch and are easy to press. However, I find it inconvenient that there is no play/pause button. There is a harder edge of soft material on the bottom, which keeps the speaker stable. The speaker is angled slightly upwards so that I can hear the sound clearly when I place it on a low table. Thanks to the slim design, I can easily slip the speaker into my bag.

Atmospheric light The built-in light creates a beautiful glow around the speaker. Unfortunately, the light is not bright enough, so it does not illuminate the entire room. There is a button on the speaker that allows me to quickly adjust the color of the light. I can choose from more settings in the Harman Kardon One app. In addition to the color theme, I can also adjust the brightness and the speed of the light's movements.

1 is good, 2 is better

Sound quality
Design

I had one first and was already quite pleased with it, but I bought another one to pair them for stereo and man... that's when they really come into their own. The sound is truly beautiful, with lovely bass like I hadn't heard before on Bluetooth speakers. Nice mids and highs; they are on par with a more expensive hi-fi set.

A speaker that deserves to be heard and seen!

Beautiful design
Nice sound
Powerful
Sometimes the bass is a bit overpowering.

It is certainly a good speaker in this price range, especially since it looks nice in your room or office. It has more class than those JBL speakers, which are mainly intended for outdoor use and are often moved around. I wouldn't pick this one up very often because of the fabric covering, especially if you have the grey one. I can imagine that you might get stains on it at some point.

What I do find really disappointing is that you can't change any settings (except for volume, of course), either via an app or on the device itself. As a result, you have to make do with the sound that comes out. Ideally, I would like to be able to adjust the bass or treble. But then again, you have to go into a higher price range.
