Wired headphones connect to an audio device and the only thing separating them from the device is the headphone cable. Therefore, there are only a few meters between you and your device whenever you use a wired headset. Wired headphones typically have a 4 to 6 foot cord attached to the left ear cup. Wired headphones receive an analog signal that can handle more data than Bluetooth®. Hence, it provides better sound quality. ANYWHERE - As long as there is a 3.5mm jack, wired headphones can be connected to any audio source.
