With over 200 LED's, Excellent visibility, hundreds of possible patterns and a 4+ hour battery life, these glasses are made to grab attention...   oh and they sync with each other. One remote (optional but not needed) is all you need to synchronize dozens of glasses. These were designed to make you and your crew part of the music.

These circular rave glasses are made to party! (Looking for Heart shaped ones? https://www.madebysloan.com/product-page/wireless-heart-led-rave-glasses) Our priority was a slim design with maximum visibility and LED count. We offer each design of glasses in a fully wireless version (with a built in 4 hour battery),or you can save a few dollars and choose an external battery with the same tech and synching functionality but the battery will live in your pocket. The external battery connects with a magnetic cable on a 360 degree swivel so you can easily and comfortably wear them while plugged in. The cable is 3feet/1m long, perfect length for hiding behind your ear and reaching a jacket pocket without having too much cable getting in the way. Every pair is designed and manufactured by us in Edmonton, Alberta, Canada. We are proud of our products, all customers new and old are always just 1 message away from speaking directly with us. Questions, problems or comments, we always like hearing from our customers and do all we can to make sure your glasses will run well for years to come.
how does this sync tech work? BeatSync is what we call it. This is what sets our LED tech apart in a crowd. Every single BeatSync Product has a wireless chip that lets you sync them up to our remote and thus synchronize a whole group of devices to move together. One remote can drive countless devices so you only need one remote in your radical rave roost to keep everyone synchronized. Pass it around so your ppl can take turns changing beat timings, animation styles and colors live in time to the music.
Want to keep it simple? No problem. When no remote is in the area, the glasses will loop through all the installed modes with your favourite color showing up most often (this is why we ask for your favorite color at checkout).
How many modes are there? 8 animations ship with the glasses, but with all the color and speed options available there are hundreds of unique combinations, and countless more will be available via free software updates.
Are you locked into the 8 modes that ship with the glasses? No :D. 
Every pair of glasses has a micro SD card hidden in it, modes can be swapped out in just a couple minutes with no programming experience required. At launch the glasses will ship with all the available animations already installed. More animations will come available in the coming weeks, months and years. You have our guarantee that new animations will always be compatible with older glasses, so if you pick up a pair today you can keep it up to date with the latest animation releases.
