It’s the lowest-tech device that can do this with sufficiently low running costs to make it free to use. Much better than the more common infrastructure of QR codes and a server of audio files (or worse, app!)
And there are hiking trails with information panels that have this technology (the button switches narration languages or bonus tracks) for accessibility to the visually impaired built into the post. It does not need to be this big (you know how tiny an exercise bike generator, 10W power regulator, MP3 player, amplifier and speech-capable speaker can get) but the tall-human-sized bent pipe is an artwork by itself.
