My 10 year old son was very disappointed with these goggles.
The light, which is a high intensity red LED, the type used for rear cycle lamps, is the main problem. In a dark room at night the light could illuminate something about 1 meter away - much further away and the light failed completely. As for the "sonic ear listening device", it seems to amplify something that is already very close to the microphone (which is built into the headband of the goggles) but that's about all. My son whispered from about 3 meters away and I could hear him better with my naked ear than I could hear using the listening device on full volume!
