Select according to compatibility and use

Llamas stressed how important it is to choose smart glasses that are compatible with mobile devices.

"Remember, we're not yet at the point where these are completely separate from smartphones, and compatibility with smartphone platforms is key." Another consideration is multi-platform support, so you can pair them with computers, game consoles, and other devices.

"Smart glasses can also bring new conveniences, depending on the apps you use," Llamas added. Keep this in mind considering the apps and software you use every day.

Also, start thinking about how you want to use smart glasses. Business games. Home automation. Listen to music at leisure. Whatever it is, make a list and see which pair meets your needs.

Choose the right type

The two most popular types of smart glasses are bone conduction glasses and open glasses. Both come with a traditional glassy look that allows listeners to stay aware of their surroundings. However, each of them offers a different fit and performance.

Bone conduction glasses have an external speaker that sends tiny vibrations through the skull, bypassing the eardrum and transmitting sound directly to the inner ear, while open-ear glasses have speakers built into the frame that project sound to the ear. Neither of these headphones can produce audiophile sounds like the best truly wireless headphones on the market, but they offer a more unique, discrete way to listen.

Sag recommends checking the design to determine "how acceptable they look," as well as the weight, as it can affect "long-term wear resistance."
