Q. I’ve listened to the radio to deal with insomnia for years (Dear Mary, 18 February) and your suggestion of single earphones does not work well. They hurt your ear — when they haven’t fallen out of it. The answer is either a Roberts Radio Pillow Talk speaker (flat, sits under pillow, clearly audible through pillow) or a Sound Asleep Speaker Pillow (haven’t tried myself but has 49 good reviews on sleepypeople.com).
