 When I received five e-mails to check out the MC Square—a handheld device that's said to relieve stress, improve memory, and enhance concentration through light and sound—I knew I couldn't pass the opportunity up. (My memory is horrible!) Plus, 1.5 million units have already been sold in Korea, so it's gotta be legit, right? And for the first time starting today, it's available in the U.S.Dragging PCMag.com assistant editor Corinne Iozzio with me to the W Hotel in Times Square, we were presented with a device that looked like a sleek MP3 player connected to earbuds and goggles. Developed by Daeyang E&C, the MC Square features six program modes with natural sounds like rain drops to soothe and relax your mind. With everyone in the stuffy room watching us, we both put the earbuds and goggles on. We turned on the player and began to see red lights flashing at our eyes. We were told to close our eyes and listen to the sounds of the ocean in the background. The combination of light and sound, an audio-visual stimulation (AVS), is known to cause "significant changes in EEG patterns and cerebral synchronization." But why the flashing red LEDs? They're "bright, inexpensive, and blood vessels in the eyelids pass red/orange light most efficiently."
Korean students found that after regularly using the MC Square for 15 minutes a day, it improved their study skills. One such student said that he was able to memorize vocabulary words in just 10 minutes after using the device, as opposed to more than half an hour. That's a significant difference! The MC Square isn't just a stress-reducing device. It's also an MP3 player with 512MB of onboard flash memory and a mini SD card, as well as a digital voice recorder (30-hour capacity) and image and text viewer with a color OLED screen. The player is very portable, too, at just 0.6-inches thick. We're expecting to get a unit in-house, because we just have to see for ourselves if this wacky device works. You can order the MC Square for $399, which comes with the player and earbuds, at relaxmc.com. To purchase the MC Square with earbuds and goggles, it sells for $437.89 at Amazon.com.

Corinne never looked so relaxed!

$400 for a 512Mb music player!!! (oops, I almost forgot the lights) What a ripoff. Who in their right mind thinks this has anything to do with memory?

I suspect a little "placebo effect" taking place in those who claimed to have improved memory.
To those for whom this worked: I have an Energy Hat for sale. You place this aluminum foil......errrr Patented Metallic Alloy helmet on your head for 15 minutes, and you instantly gain energy! Only 49.95 plus S&H!

That device looks very similar to "Bob and Bob's Magical Mind Trip Machine". Does anyone else out there remember the Bobs and this device from San Francisco rave parties around 93-95? I recall the LED flashing lights and music being quite soothing, but it may have had something to do with my state of mind.

I'll wait for the randomized double blind tests from unaffiliated scientists if it's alright with them.
Then I won't buy it because my concentration and memory are already great.

Those Koreans have simply reinvented what has been available in Europe and the US for a long time, say,
at least 25 years. And then to include the MP3-player-feature !!! Is quite a proof that they know that the gadget is not worth half of the sale-price. Six program modes ? They must be joking...I have got a German-made device with over 50 programmed modes, each from 25 up to 55 minutes, and the possibility to develop and save new programs, selecting pitch, various types of binaural beats, a.s.o. - And I paid something around 1.000,00 German Marks for it, at a time when 1 US Dollar bought 2 German Marks.
I can only doubt that they have found more than 1.5
million "stupid" Koreans ...

I think Paolo is getting too jealous of "Smart" Korean people.....
The device looks pretty interesting to me and I have seen a lot of positive user feedbacks from media and actual users, which were posted on many web sites.
I agree with Kevin Jones.
Paolo needs to go back to wherever he came from.

As with many things, the hype often doesn't correlate with the science (otherwise we'd be getting our power from Con Tesla rather than Con Edison!)
For instance, Sharp Brains recently reviewed the brain fitness product market to see which products had the scientific credentials to back up their claims. They gave Posit Science the best score but it was still only 5 out of 10... (Lumosity is the big fish in this pond and they scored 2 out of 10.)
The MC Square seems like an expensive gimmick. Does it work? I'd like to see the research.
One academic study proving that brain training can increase general intelligence is Susanne Jaeggi and Martin Buschkuehl's study on Improving Fluid Intelligence by Training Working Memory (PNAS April 2008) which recorded increases in mental agility (fluid intelligence) of more than 40% with less than 20 days of focused brain training.
I was so impressed that I contacted the research team and developed a software program using the same method. I've been using the training myself, of course, and the results are far from subtle. I can now tackle, and complete!, the Saturday crossword puzzle, for instance, when before I used to get stuck on Thursday.
IQ Training Program
And I've kept the price under $25!
