JBL speaker 104BT. reference monitor speaker. need to read this before buying.

  

 Today, I would like to share a review of a speaker that I have used for over a month.

speaker selection

Personally, I'm sensitive to sound and music, so I've been buying and selling used and new speakers over and over again.

In the meantime, I felt the need for a speaker with clean sound to use when listening to music on a PC or occasionally editing video, so I started searching.

One thing to keep in mind when buying a speaker is the brand.

I'm not sticking to a specific brand, I choose a company with at least a few decades of business history.

This is because sound quality is a field in which it is difficult to achieve high results with technology in a year or two.

When choosing this speaker, I chose the JBL brand.

JBL?

Founded in 1946 by James B. Lansing, JBL began to install JBL's speaker systems after the 20th century theater was built, establishing itself as a professional speaker brand in the United States.

In the 1950s, JBL made a name for itself in the audio industry with its legendary loudspeaker systems, with the release of vintage classics, the Hartsfield and Paragon.

Since then, it has become known as high-end audio and has started to gain popularity.

Choose your JBL 104BT model

As mentioned above, there are very few "reference monitor speakers" available to the general public for clear sound quality speakers.

Among them, the most reasonable price was the JBL 104BT model.

The latest version supports all 5 inputs and even supports Bluetooth.

Although the number of prints is not high, it has all the features I wanted, so I was able to choose right away.

There doesn't seem to be a monitor like this for writing next to a PC.

When listening to music, there is no hum or noise at all.

Other than that, if you work on music or edit videos on YouTube, please give it a try.

I highly recommend this product as I am very satisfied with it.
