I would not consider these to be smart glasses as they only have speakers and Bluetooth. I think to be considered smart glasses it should have at least one other tech feature.
These Bluetooth glasses are good do listening to podcasts or audio books. As for listening to music these are not the best choice. The sound has no bass and simply lacks depth of any kind. I listen to podcast daily and enjoy wearing these for that purpose.
I love music and have to have bass or it doesn’t sound right to me . I have not found a good pair of Bluetooth glasses that have good enough quality speakers to listen too and fully enjoy music on.
I have had better quality glasses that cost less , and worse quality glasses that cost a lot more.
Whole these are not perfect they are decent value depending on your audio preferences.
These fit nicely and charge fasts. I use these intermittently so the battery lasts for at least several days. They have not been completely dead yet, I don’t want them to die in the middle of a podcast.
These are easy to connect to Bluetooth
