Why Do You Need A Spare Earphone? If you're a music lover, chances are you're not happy with your phone or media player's bundled earphones. Most of the time, they sound pretty dismal. Some devices don't come with any earphones at all, but even the models that do include them tend not to offer a high-quality listening experience. Your music and video can definitely benefit from an upgrade. How To Choose An Earphone? Wired or Wireless? Wired earphones are generally less expensive, and you don't need to worry about keeping them charged. Bluetooth earphones are more convenient because you don't have to physically connect them to your smartphone, but they need battery power to work. For the most part, you won't find a 3.5mm port and removable cable on Bluetooth earphones; when they're out of power, they're out of commission until you charge them again.
