HI Vikki
However, there is a headset that I bought as my first set (currently have a DC 13.4) which I found to be very similar, with respect to both noise and weight (also have gel seals), however, I'm not sure if they are available in the UK. They are significantly cheaper than the DC's (even with postage to the UK), and might be a good option for you.
