So-so experience
If you buy a ticket to the Book of Kells Experience in advance, the system now sends you a suggestion to bring your own headphones along, which is the only reason I did, so I at least appreciate that. But according to their own materials, the app is supposed to trigger audio when you get near a relevant point and on my iPhone that never once happened. There are also no signs telling you when you’ve reached an audio point (as is typical at museums/sites with audio guides) so it took me at least ten minutes in the extremely crowded exhibition before I realized it was completely up to me to regularly check the app to try to figure out if I was at an audio point. The content itself is good (albeit not as in-depth as I personally would have expected) but even with noise-canceling AirPods, I had to turn the volume to maximum and still sometimes had difficulty hearing as there were fellow visitors listening to the audio guide on speakerphone and no staff ever asked them to stop.
