Sennheiser
Hello everybody,
I am a pilot flying a Boeing 737-800 and I am interested in buying a Sennheiser headset with Active noise reduction. The thing is that there are like 10 different models. Most of the people I have seen wear this headset have the 25KA, but does anybody know the difference with the KAP,KAL,KAX,KAP,KA?and also if there can be used in the Boeing 737.Thank you in advance
