For the pan I'd try Paiges in Shaftesbury Avenue - our catering-quality pans we've got from there seem to last for ever. They have big saute pans, what they don't have are woks (which is why we buy a new one every 12 months).

I've been looking for retractable headphones too. Tell me if you find any - they don't need to be as good quality as you want them for.
