Here is a wearable device that goes in your ear instead of glasses.
 

This is the Moto [motorola] Hint. It's a bluetooth earpiece that fits in your ear and pairs up with your smartphone. Your phone can be in your purse, backpack, golf bag, glove compartment or toolbelt if you are looking for a reason to wear a toolbelt again..

I think it would work for me when I'm golfing, driving or biking. What do you think?

I tried a Hint last Fall. The maximum volume level it could achieve was too soft for me to hear it in anything but a fairly quiet room. There is no volume adjustment control on the device itself. You can only control the volume level with your phone.

That's disappointing. Did you get to try it out in a store?

No I ordered one direct from Motorola to accompany a Moto X (2014) phone. I kept the phone, but sent the Hint back. Your hearing may be better than mine so it is worth a try if you get the opportunity.
