Summary
Wires are messy and you can get tangled up in them, so the wireless alternative feels much more natural. The Beyerdynamic RSX 700 Wireless Headphones works when the supplied docking station is connected to your iPod via the 3.5mm headphone jack.

You can then move around your home or office and as long as you’re within a 20m radius from the docking station you will hear your iPod’s tunes in perfect, crystal-clear quality. In fact these headphones are so light and they cup round your ears so gently you might not want to stop listening to your music!
