Brainwave Cat Ears

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 (=^_^=)

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.

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

These necomimi seem to work great. The twitch and rotate and I did notice that when I became focused on one thing (namely something happening on the TV that caught my attention) they did one singular motion twice and not the initial pattern when I first turned them on. I haven't used them for very long just yet but I will be using them over the weekend for my birthday and again for Halloween. They seem to be made for slightly larger heads than my own but still fit comfortably. If you position them properly there's not discomfort with wearing them. We'll see how long the AAA batteries last for me. Oh... don't let a cat near the actual ears... mine tried to eat them.

I don't really think it has anything to do with brainwaves as advertised as the movement seems to just loop/repeat after "syncing." All of those bulky pieces are annoying to hide for cosplay plus it's a bit heavy. For only taking AAA batteries the casing is huge, plus it chews through them so I highly recommend a good pair of rechargeable batteries. The motors that move the ears are also quite loud. It would be more worth it if they were less expensive. I am also lucky that I have a small head because there doesn't seem to be a way to adjust them- also the ears "hover" a little and don't sit quite flush to my head with the band. The foam ears they came with are also just faux fur covered triangles with no depth so in the near future I plan to make my own for more realistic looking ears. I had expected more based on how they were advertised but they are still a fun toy.

These are neat. Takes a few minutes to calibrate, but then they started working as advertised. Only complaints are that they are noisy and the ear clip hurts after awhile Update: I liked these so much, I bought another set for my wife to go to anime events. I don't have enough hair to hide the mechanism, so I bought a wig. To my surprise, it continue to work through the holes in the wig. I guess since the ears never wrap all the way around, it doesn't get tangled in the hair. At anime festivals, there are always a few panels where a local professor discusses Japanese culture. I like standing at the back of the room with the wig and ears. It perplexes the professors to see the ears move. Unfortunately, the ear clip is made of cheap plastic. The plastic bearing broke on both sets after a year. The price seems to have doubled since I bought them, so I am attempting a repair using eyeglass washers, rubber bands and epoxy. Update: The repair worked.. The real problem is that the spring inside the ear clip is way too powerful. When you wear the ears, it actually hurts your ear after awhile. Anyway, that spring actually pulls the ear clip apart. I don't know this for a fact, since both my sets have broken ear clips, but I think if you wrap a rubber band a couple of times around the end of the ear clip so that the contacts are barely touching, the ear clip will be under compression and less likely to fall apart. They will also be more comfortable. The way my ear clips shattered was that the half with the inner bearing was fine. The half with the outer bearing had the top of the bearing crack off. So, I made a new shaft by cutting a paper clip with a set of pliers. I thread the shaft through the clip half with the good bearing and placeed that on top of the half with the broken bearing. Then I put 5 minute epoxy on the outer portion of the broken bearing and slid eyeglass washers on either side of the shaft pushed them against the epoxy coated bearing. So, the epoxy is going to bind the washer, the shaft, and broken bearing together. I held it in place for 4 minutes, then kept tapping the clip in case some of the epoxy leaked onto the inner bearing. Didn't want that glued together. After setting overnight, I just wrapped a rubber band 3 times over the shaft to provide the tension. You can scootch the rubber band a bit to adjust the tension. Discard the original spring. It was the cause of the problem in the first place. Just use the rubber band. This repair has held up for 2 anime events so far and still seems good.

There is a lot of some invited silicone, making all the softer parts sticky and disgusting. The black goop comes off on everything. I didn’t even want to put it on my head. The look is chunky and I ordered a second pair which also came actually broken with loose pieces and still covered in uncured sticky black gross stuff.

This is a great product!!! It is extremely cute and it moves according to my moods. Just make sure that you have batteries when you get them! Sometimes it does take them a while to calibrate. If they seem like they're moving randomly, try turning them on and off. The ear clip is comfortable. However, the band is a little tight and sits uncomfortably on my head. The ears are awesome, they're super soft! Over all I love them!
