As an alternative: Softcomm C90 (
Company website ). I do not have a clue who sells them around the UK (as I bought mine in Florida) but for the same price as a non-ANR DC 13.4 I find it a very comfortable headset with a decent ANR system. The sound quality of the DC 13X is slightly better, but at twice the cost...... I found it an easy choice. It's given me excellent service since.
Still the best thing to do is to go out and try them on, if it doesn't fit right then don't buy it!
