So what are sunglasses doing on an iPhone site? Well, they are smart sunglasses, with Bluetooth 5.0 and a microphone built-in. You can listen to music or talk for up to 8 hours on Mutrics' crowdfunded Smart Sunglasses (starting at $69), with a whopping 200 hours (claimed) of standby time. We'll see when the final version ships, but those are good numbers.

I liked the stylish chromatic lenses plus classic RayBan-style frames in either white, black, or orange. There are buttons hidden out of sight under the bottom of one of the temples. It took just a few seconds to learn how to use them. I paired mine with my Apple Watch and was good to go. The glasses are expected to sell for $159 but are available at a great price of $69 on Indiegogo. Another nice touch is interchangeable lenses and a magnetic contact-based charger similar to Snap's Specs.

Pros
- Stylish chromatic lenses, white, black, or orange frames
- Buttons hidden out of sight
- Promising battery life of 8 hours or 200 standby
- Great price on Indiegogo
- Surround sound with phone call capabilities
Cons
- Pricey post-crowdfunding campaign
Final Verdict
The Smart Sunglasses from Mutrics deliver surround sound in style.
