Those Bose sunglasses with the speakers built in look great. The bone conduction headsets sound like great ideas. I haven’t tried either. I do have something I like a lot. I’ve tried all kinds of sound systems on the bike, and this latest one beats them all. It’s a collar bone speaker/headset. I feel like I’m more aware of the sounds on the road than is a car driver with the windows open. I can hear my audio and all the sounds I would normally hear without the headset. This is ideal for me.
I use it inside, too, now for listening to radio, podcasts, and phone calls. I wear it all day long from rising out of bed until I get in bed. It helps me as I’m starting to lose my hearing so I can’t use my phone handset anymore.
