You may think that mp3 players already lost the battle against smartphones but there are still some benefits that make mp3 players worth buying. The only purpose of an mp3 player is to play music, which allows manufacturers to install better hardware components, improve audio processing, and boost the sound quality. Also, having a separate unit for music playback will unload some burden from your smartphone and allow it to perform faster and smoother. Also, tiny mp3 players that you can attach to your clothing are much more convenient for workouts and jogging that large and hefty phones. So, yeah, mp3 players are still worth buying.
