Making the iPod smaller might mean it fits into your pocket easier, but there’ll always be the earphone cable to contend with. Unless you invest in a Bluetooth set-up like this Anycom headphone bundle for the iPod.
It can be used with all iPods (except the shuffle), allowing you to listen to music and control important functions, as well as working with your Bluetooth mobile phone. The headset has four buttons to control all important functions (volume up/down, call answer/end, redial/mute, next/previous title, pause/start) and can be used with a range up to 10m metres away.
One charge offers 12 hours of listening (with 200 hours standby), with charging via USB or AC power supply. It’s avaialble now for around £120.
