If you grab a sense, the movement of the ear can be controlled by brain waves. I is transmitted the feeling of movement in the ear. Technology has come true, I am pretty, It is the form of the new little communication. 4 AAA alkaline batteries (not included) Product Warranty: Age: 14 years old use the battery to the product of 90 days This, maker certificate is not attached in the policy maker, but 90 days warranty there. Review: Oh hell yes - 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 (=^_^=) Review: 2 sets broke within an hour - 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. ## Features - battery: use - target Gender: unisex - Age: from 14 years 0 months - safety standards: FCC CE - The main production country: ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007YNBOJM | | Customer Reviews | 3.8 3.8 out of 5 stars (348) | | Department | unisex-adult | | Is Discontinued By Manufacturer | No | | Item Weight | 7 ounces | | Item model number | 8037-003 | | Manufacturer | NeuroSky | | Manufacturer recommended age | 18 years and up | | Product Dimensions | 4.72 x 10.83 x 5.91 inches | ## Images ![Brainwave Cat Ears - Image 1](https://m.media-amazon.com/images/I/512RhP62a1L.jpg) ![Brainwave Cat Ears - Image 2](https://m.media-amazon.com/images/I/61Dcg0eXHTL.jpg) ![Brainwave Cat Ears - Image 3](https://m.media-amazon.com/images/I/51SrDo-SBbL.jpg) ![Brainwave Cat Ears - Image 4](https://m.media-amazon.com/images/I/51sTHmSVT2L.jpg) ## Questions & Answers **Q: Are these for kids?** A: I bought them for my 16 year old daughter and they fit perfect - I imagine they would be too big for small kids **Q: Does this device arrive in working order?** A: It doesn't come with batteries. Triple A is what you need. **Q: How long does it take for the ears to calibrate?** A: Once powered on, it takes about 15-30 seconds. The ears will wiggle while calibrating. **Q: Do these have a warranty in case of damage while being shippe?** A: There really isn't a warranty, but if you receive these already damaged, you can return them and get an amazon refund. I had to do that because the ear sensor was broken when it arrived. Amazon will email you a return label and once UPS has checked it into their system for a return then Amazon will give you online gift card credit for the same amount of the item purchased. You'll have about 30 days to return the item. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Oh hell yes *by G***4 on December 26, 2012* Probably the most hilarious thing out of Japan in awhile.

Definitely used, not great *by B***E on March 6, 2025* 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 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/1980599-brainwave-cat-ears](https://www.desertcart.dk/products/1980599-brainwave-cat-ears) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-23*
