Beautiful speaker for your home with powerful sound

Powerful sound
Classic design
Easy operation on the speaker
Slightly distorted sound near the wall

The speaker is a beautiful addition to my interior. It produces a loud sound, allowing me to hear the music clearly throughout my living room and open-plan kitchen. The speaker produces a slightly distorted sound when placed close to a wall.

Stylish design The speaker has a luxurious look thanks to the black leather. I think it's a stylish addition to my interior. The buttons and switches feel sturdy, giving the speaker a solid feel. The speaker fits nicely on my open-plan cabinet.

Easy to use The speaker has three buttons that control volume, bass, and treble. This allows me to quickly and easily adjust the bass and treble. I turn up the bass for pop music because I love a strong beat. For classical music, I turn up the treble so I can clearly hear the higher instruments. With a button, I can quickly skip to the next or previous track and pause the music. I appreciate being able to adjust these settings so quickly without needing my phone. This round button, which I use to pause the music and skip to the next track, is very touch-sensitive. This causes me to suddenly skip to the next track, even though I wanted to pause the music.

Powerful sound The speaker can handle very high volume. At half volume, the music can be heard clearly throughout the living room and kitchen. When I set the bass to maximum, I enjoy a powerful bass. This really comes into its own with music with a clear beat, such as pop and techno. The strong bass adds depth and makes the music sound more lively. I also set the treble to maximum, which allows vocals and instruments to sound clear. I avoid placing the speaker against a wall, as this can cause the sound to be a bit distorted and muffled.

What I expected

Beautifully built
Fairly large, so full sound

Mains power only, so battery life is n/a. Good sound, solid bass, good vocals.
