I’ve recommended plenty of headphones and earbuds over the years, but these stand out as an excellent companion for the VoiceMap app.The Ray-Ban Meta Smart Glasses have speakers built into the arms, delivering open-ear audio. This means you get great sound for your tour narration without being completely cut off from the world around you. On a walking tour, that’s a big safety win — you can still hear bicycle bells, car horns, or someone calling your name.
