What are "Whispers"

"Whispers" are the radio transmitter and receiver Colm and local guides will use to communicate with us. See the blue wire/earbuds we are all wearing here. The local guide in the middle here has the transmitter and is telling us all about this castle. The "Whispers" is a nickname Colm gives them and they allow communication over a wide range which is really nice because you can wander around and still hear what you need to quite easily. Colm will issue everyone a receiver and single earbud at the introduction meeting the first night. They use a standard 3.5mm jack and go in one ear but if you want to bring your own wired headset you can. At the Roman Baths in Bath they use an audio guide similar to a phone but I noticed that the handset has a 3.5mm audio jack and I thought that a headset would have been much more comfortable. The "Whisper" bud should work with this but you might want your own stereo set?
