Hi Vikki
All sound advice so far.
DC is great and very tough to beat. Hardwearing but at a price.
If I deduct (?wrongly) that you are a lady you may consider that they are the only company that do a headset which is smaller which some people find more comfy. (i.e. my wife)
Best bet would be to give a few a go or go to one of the shops (Transair/AFE/RD Aviation) and try which one fits your noddle best.
Keep it on for as long as you can stand being looked at by the other punters.
