Old Telex Headset
These headphones were worn by many professional airline pilots back in the 1960s and 1970s. I bought mine about 1972 and they are still my favorite for long periods of operaton. Of course if it's cold, then I switch to the Sennheisers (just to keep my ears warm).
These were ideal for my motorbike expeditions. They are lightweight and don't take up much baggage space.
