To achieve a wider range of sound, look at the fine print on the packaging to see what the frequency range is (the Hz). The first number is the bass (the lower the better). The second number is the high frequencies (the higher the better).
Remember the 20/20 rule. Try to buy a pair where the first number is 20hz or below. And the second number should be 20,000 or higher (sometimes it’s called 20khz).
If the packaging has no information about Hz, put it down and slowly walk away.
