When it comes to headphones, there are two main types: open-back and closed-back. Open-back headphones have grilles or vents on the back of the earcups, which allow sound to escape. This results in a more natural sound, as it allows the sound waves to reflect off of your surroundings and reach your ears. However, open-back headphones also leak sound, which can be a problem if you’re using them in a quiet environment or if you don’t want others to hear what you’re listening to.
Closed-back headphones, on the other hand, have solid earcups that block out sound from the outside world. This makes them a good choice for use in noisy environments, or if you want to listen to your music privately. Closed-back headphones also tend to have a more bass-heavy sound than open-back headphones, which can be appealing to some listeners.
