The best all round headset
After 20+ years in the job in a large variety of types and classes the Bose X is without any question the best I have ever used, a little expensive but worth every penny. You can also upcup one ear when flying pressurised jet types and it remains comfortable, I have flown up to 12 hour sectors with the Bose in great comfort. Dave Clark H20-10 also not bad as is the 13.4. Overall if you can afford the £700 for the Bose its money well spent, after all you are only issued with one set of ears - they are worth looking after!
Safe flying
