Are noise cancelling headphones allowed during a competition? I would imagine not but it never hurts to ask. The relevant section of the regulations to this is the following: [quote:1zzqglub]2i) While competing competitors must not use sound equipment, other electronic equipment (like walkmans, dictaphones or additional lighting).[/quote:1zzqglub] I would interpret this to say that noise cancelling headphones are not allowed, but as I said before it never hurts to ask.
