“Thanks for using our Bluelooth sunglasses! We attached the user manual which can make you operate the player skillfully.”

My mom bought me a virtually identical pair of these Bluetooth enabled sunglasses last year and I liked them so much I ordered a second pair (as backup) earlier this year. The eBay seller I bought them from sold them for $7.44 USD with free shipping to Canada. They took nearly 4 months to arrive – but they’re here and I’m all excited again! The original set cost maybe about $30, showed up in a different box, and came with a little black hard-shelled zipper case. Otherwise they look absolutely identical. I notice the female voice in the software, saying words like “connected” and “on” and “off” are different, and the name of the device when connecting via bluetooth is a different name, but they are otherwise identical.

So why Bluetooth sunglasses? First because Bluetooth. I hate cables – they get tangled – they’re annoying. Second, SUNGLASSES! It is summer and the light is too bright and you need sunglasses. So that’s why.

I love these Bluetooth sunglasses. The fact that the volume level is variable via multiple methods is so great. First, there are the up and down volume buttons (which I generally ignore, but are nice to have I guess), next you can up and down your glasses volume using your phone’s slider or volume up/down buttons (just like regular Bluetooth earphones) but best of all is the third way. A third way that is faster and more demonstrative than all of the preceding methods– the ability to physically pull and/or tilt the speakers towards or away from your ears.

When some fellow human, you know the kind – the ones out in the world, deigns to say something to me unexpectedly, like “beautiful day” or something like it, I can bring up my hand, tilt an earbud away from one ear, and say: “Totally!” This gesture shows the human that I’m listening to them and also allows me to actually hear the creature without necessarily having to turn off or pause my audiobook.

I can see you looking at my sunglasses. You’re looking at them and you’re judging them right now. You’re looking at them and you’re thinking – those– those are ugly. And I know you’re right, they are ugly. But what I say to that is “yeah, they’re ugly – they’re ugly like a Kübelwagen, ugly like a jerrycan, ugly like an Ikea Jerker desk.” The whole point of these generic unbranded sunglasses with built in Bluetooth headphones is they do two jobs and they do their two jobs both beautifully and on the cheap. Whichever Shenzhen designer designed them wanted to incorporate two things that go on your head (sunglasses and headphones) and that designer did it.

Funny story. For months I walked around, wearing these glasses, and wondering at one particular aspect of the design. I asked myself, “why do they have all this thickness at the bridge of nose and almost no support for the lenses on the edges?” I speculated, idly, wondering if it was for durability. Then, one sunny day, ruminating at the fact that my sunglasses had to be worn atop my head when I went indoors (they are too fiddly and bulky to fit in the pocket of a pair of shorts and to bulky and heavy to hang from my shirt collar), I wished that these terrific cheap sunglasses I was wearing had a feature that would allow me to walk around indoors without the lenses over my eyes. You know what I mean right? I’m talking about those flip up sun-glass lenses that can just clip-on to regular glasses–anyway, I was thinking about this– and thinking about how it would be cool if those amazing iterating Shenzhen wizards could make a design that…. and then suddenly I realized that they already had! Yes friends, my sunglasses had flip-up and flip-down lenses and I had never known!

Bluetooth Sunglasses - FLIP UP!

Now, do I actually walk around looking like a doofus wearing my Bluetooth sunglasses flipped-up when I’m indoors? Yes, I’m afraid I actually do. They do look ridiculous. But they’re doing what I want them to do and that is far more important than me not looking ridiculous.

In terms of other functionalities. I should just say everything works great. There are three buttons atop the right nacelle – the center one (the only one I ever use) is the on/off button – holding it for a few seconds turns the glasses on or off and either connects or disconnects them from whatever phone or tablet is nearby. They work terrifically, always pairing quickly, and get a better signal than my Bluetooth earphones. And the battery lasts all day (for me anyway). Now I should point out that the sunglasses say nothing about being waterproof. In fact I bet they are really not at all waterproof as the charging port is a non-waterproof micro-USB at the bottom of the right nacelle. But I’ve sweated in them, got rained on lightly and they’re still working and the a little LED still shows red when charging and still turns blue when fully charged.
