Can someone find the charger for these Headphones?

Hi, I went to the US a few months back and bought myself a headset... exactly this: http://www.amazon.com/Sentey-LS-4560-Bluetooth-Wireless-Headphones/dp/B00PYW5X1A

So i got back to the UK and after a few days of using it, the USB charger to charge the headset (shown in the picture) broke as it was really poor quality.

I've been struggling to find a cable that can charge the headset - in the UK. A standard 3.5mm > USB didn't work so I'm unsure where/what to look for. Any assistance would be greatly appreciated, drop a link to something that should work if you can - or an alternative method of doing this.

Thanks,
Ray

Edit: I got the sound to work by using an auxiliary 3.5mm - 3.5mm but the microphone isn't working

Is the cable you used three pole or four pole?

I have no clue LOL. It's on here: http://ecx.images-amazon.com/images/I/8163aKVUoNL._SL1500_.jpg annotated "USB Charger Cable"

It's very possible it will not carry a microphone signal over the wired connection.
