I have an ipod touch which listen to when I'm out and about and it's a great little device. However, i'm having a bit of an issue with it lately and wonder if anyone can help.

The problem started a few months ago when I bought a pair of Sennheiser Momentum wireless headphones. They sound brilliant especially but since i paired them with the I-pod, I'm having to recharge it after about 2 hours use whereas before I when I used wired headphones I'd get about 8 hours between charges. The headphones give me about 6 hours listening time before they need charging.

I know Blutooth uses more battery power but a 75% reduction in life since I started using the Sennheisers seems an awful lot.
Is there a way to get more life out of the ipod? I don't use any of the other features on it so it's music only.

If this is normal, does anyone know of a device that will give more battery life when used with blutooth headphones.

Failing that, can anyone recommend a pair of great sounding wired headphones (in ear type) that won't cost a forune?

Thanks in advance
