Sennheiser’s updated active noise cancellation HMEC 26-2 headset adds comfort, noise protection and a higher sound pressure level to the HMEC 26. To improve the fit for a wider variety of pilots, Sennheiser redesigned the two-piece automatic headband so it can be opened another 20 degrees. Restricting folding of the ear cups to a 45-degree angle improves wearing stability. The microphone boom is made of a new steel that remains in the set position more securely, according to Sennheiser.
