Brainwave Cat Ears

I just gave these to my wife and she is enjoying learning to control them. The instructions are only in Japanese, but the pictures were pretty self explanatory. They can be uncomfortable if you are sensitive to pressure (they rest very snugly against the head), but I can't see anyone wearing them more than an hour anyway. They take 4 AAA batteries so if you want them to work when you put them on someone, make sure to put those in! The ears are the softest ever and the device was surprisingly light. Best Part: Our Shiba Inu watched my wife wear them and whenever they perked up, she thought we were trying to play and started bouncing around. The cats do not care, but they are cats.

Fun, works great to emotions, like how can change design of ears, can be a little heavy and unconfy if worn long period of time. None the less love these necomimi device

My 2 daughters had birthday money and they had been wanting these ears for awhile so they each decided to use their birthday money on a set of these ears. So we purchased 2 sets. They arrived promptly and my kids were so excited. They had watched videos so they knew exactly how to work them. First time my 11 year old put the ear clip on, the clip broke. About a half hour later my 9 year old put her clip on and it also broke. So both ear clips broke within an hour of these things arriving. My kids used small rubberbands to "fix" the ear clips and they are able to clip onto their ears but not sure how well they are clipped on. The ears seem to randomly wiggle. My kids love them, but they don't have much concept of money. I expected the plastic clips not to break immediately for the money spent on them. We do plan to return these and because my kids love them, we will buy them new ones. I don't expect those ear clips to last much longer, though.

The ears were cute and worked well with emotions like happy and sad. Unfortunately i think this is just a phase because I don't see my daughter messing with it anymore after Christmas. So definitely don't see this going as a trend especially for the price it wants. Thanks.

I ordered two, but one was broken upon opening. The ear clip electrode was completely trashed. OK, so these are a fairly simple EEG device and uses one electrode over the left eyebrow and the ear clip. With fresh robust 4 AAA batteries, the ears really do move quite a bit. When positioned correctly, they will calibrate and then start moving. Do they really reveal your thoughts? Uh...no, but they are cute and will definitely light up any party. You will get loads of stares, giggles, lots of questions and requests to do things with your thoughts. They will also immediately state that they want one as well! They are unique and very novel. They will open an instant conversation about brain EEG and neuro-oscillations. For the price, do get these for anyone fascinated by neuroscience. Some other comments. The electrode is rather difficult to position correctly, the battery pack is kinda tough to get off, the unit will drain batteries very quickly and the gears grinding is really bothersome after a while. they are packaged beautifully and with great instructions, but sadly, the science behind these are really very sketchy as to what exactly they are sensitive to, why they work, etc. The online description of the science is missing as well. But hey, they wiggle and look cool.

I originally got these and the custom foam for my Cyan cosplay. They worked great and were a hit. I just had to style the wig to hide all the mechanisms. The forehead sensor does bend to make it easier to hide. It took a bit to get use to the extra weight. I started out with fresh batteries and only had to change them out once over an eight hour period.

They really shouldn't advertise this as new, cuz this arrived definitely used and INCREDIBLY gross in the box: little hairs or dust on the parts in contact with your head, the forehead sensor had smudges of something on it, the sensor stem had several splits in the insulation from bending, and it. Was. So. STICKY!!! The battery housing, the bases of the ear motors, and other parts were coated in a very sticky black goo that left residue on anything it touched, stained my hands black, and wouldn't clean off with soapy wet paper towels. I had to cover those parts with plastic wrap to prevent it from leaving mess in my hair and face. Everything else was fine, the fit was a tad tight but I figure it needs to be snug to prevent it from falling- but it also did cause a small headache so maybe don't wear it for a prolonged time. It turned on and moved as it should, but I'm not 100% convinced it's actually reading electrical pulses and not just randomly moving on its own. I'm glad this is only $80, cuz if this came to me in this condition after paying over triple digits, I would be LIVID. So overall, it's an ok toy to mess around with, but if you want legit good quality robotics or a serious costume piece, find something else

Probably the most hilarious thing out of Japan in awhile. My only complaints are... the device chews through batteries rather quicky (you'll get about 2 hours out of a 4 AAA's batteries) but that's easily defeated with two sets of rechargable batteries The ear socks and foamies it comes with stock are rather plain. (new ones are 14$ and up though) as far as the device itself, besides it seeming pretty fragile it works great! It's fun to see your emotions and thoughts displayed through the ears and how they react to different people. If i stick them on my 5 year old daughter, they almost permanantly stay up and tend to wiggle a lot until she gets sleepy. (yes they continue moving and reacting to your brain even when your dreaming...pretty neat) But on an adult they tend to chill out until they're intrigued about something.. also try scaring someone while they wear these (hilarity ensues) I can totally see these being next christmas' must have gift (=^_^=)
