Wired Earphones receive an analog signal, which can handle more data than Bluetooth®. Therefore, it offers better sound quality. Ubiquity: As long as there's a 3.5mm input, wired headphones can connect to any audio source, from your dad's Walkman to your brand-new laptop.

The neckband earphones allows for a combination of features you rarely ever see in in-ear headphones otherwise: active noise cancellation and Bluetooth wireless connectivity.

Bluetooth earphones include a microphone and function as a headset for smartphones, but their primary purpose is music listening.
