EQ Options: Some models offer an equalization (EQ) option, which allows you to adjust the bass and treble to your personal taste.

Design and size

Design and size are also important, especially if you want the amplifier to fit in with the interior of your home or be easy to carry around. Choose a design that you feel comfortable with and that fits the space you are using it in.

Budget

Finally, consider your budget. Mini amplifiers range in price from a few hundred thousand to several million VND. Determine the price you can afford to find the most suitable product in that price range.

Choose a reputable brand
