OK, typing in 'headset' was probably a poor choice. Try 'sennheiser' and you will get a far more detailed list of all the threads on headsets, not just sennheiser I hasten to add, only 5 pages and nearly all relevant.
I accept that the choice of headset is a personal preference.
All I am pointing out is the fact that my hearing is still tested every two years and passes with flying colours, so to speak, and all I ever used in 38 years was the headset provided by the company.
If both pilots use the Airbus or Boeing supplied headsets the performance and background noise are perfectly acceptable.
