I think why there is such mirth at headsets being the reason to join a company like BA is that the old hands know it can change the following week if/when a new Tech Manager wants to make a name for him/herself by saving money and binning the present headset and selecting a cheaper Chinese version. Hence, the advice not to select an employer by the headsets or crew meals as it could all change after you join. And then you will be a very unhappy little bunny. Good luck either way.
