When I ordered this I wasn't particularly interested in the audio feature but I've found I'm only using it and didn't even bother with the digital display which is awkward to read, when present some is a dark place near the pavement or facing the wrong way. With acoustics, you don't have to bend down or fidget. If I gave 5 stars for 'easy to read', take it as 'easy to hear'. A trick, sure, but a really useful one!
