I still have one pair of them that's functional that I keep for special occasions. I got the newer 2021 version out of curiosity. There is a big difference between the two. I'll try and address everything. 1. Rechargeable battery. Original took AAA and ate them like candy. This version is USB-C rechargable. 2. They work similarly. But slightly different. These don't move as much as the originals. That's ok though. It saves battery. Which is nice. But maybe not quite as expressive. The originals would shift into the different expressions and stay there until you triggered the next one instead of going back to neutral each time unless your brain went back to neutral essentially. 3. Sounds. This one makes meowing and purring sounds. Which you can turn off. Honestly could do without. Waste of battery in my opinion. 4. Worth the money? Absolutely. Especially if you were a fan of the originals. They're a lovely toy and quite fun. Batches pop up for sale on occasion. I'll probably pick up additional pairs. 5. Fit. Rigid headset. Fits well. It is tight and flexible. Has strap holes for a band along the back. Should fit kids and adults alike. However wearing it for prolonged periods might cause a headache. 6. Servos are quiet. Which is a marked improvement. The old models had very loud servos. 7. Cosplay compatible? Maybe. It doesn't sit quite flush with your head like the originals. So you might have to work with it a bit. 8. Needs adult supervision. Definitely. While these are a "toy" they're a nicer toy which should be taken care of properly. I'll add more as I play with them more. Review: Each Replacement Was Defective. - I don't get the high reviews. I have received three, each one has been defective. One of them, it never calibrates. Always beeped. Replaced for another one where the ear servo was grinding really bad as if going past the limit of the device. Returned and replaced with another. This new one shuts off after a minute of use, despite having been charging all night. Absolute trash. Even if it worked, the headset is uncomfortable, heavy, loud and just not fun to use. It really is random as to what it will do. Again TRASH! No wonder they discontinued this product. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09G14T7ZG | | Age Range Description | Adult | | Best Sellers Rank | #243,650 in Toys & Games ( See Top 100 in Toys & Games ) #540 in Storytelling Toys | | Brand Name | NeuroSky | | Color | White | | Customer Reviews | 3.4 out of 5 stars 71 Reviews | | Educational Objective | Educate about brain waves and mental states, and introduce users to EEG technology. | | Is Assembly Required | No | | Item Dimensions | 6.69 x 11.42 x 2.36 inches | | Item Weight | 0.18 Kilograms | | Manufacturer | NeuroSky | | Manufacturer Maximum Age (MONTHS) | 180 | | Manufacturer Part Number | 311 | | Material Type | Plastic | | Model Number | 311 | | Number of Batteries | 1 Lithium Ion batteries required.

One of them, it never calibrates. Always beeped. Replaced for another one where the ear servo was grinding really bad as if going past the limit of the device. Returned and replaced with another.

It really is random as to what it will do. Again TRASH! No wonder they discontinued this product. ### ⭐⭐⭐⭐ Loud. A bit painful and slower than previous models *by A***S on September 13, 2025* Annoying as hell meowing and tight on someone with a wide head. Convenient charging, no more AAA batteries. I feel like the sniveling behaviors have changed in this model: the reading is not as sensitive. ## Frequently Bought Together - necomimi 2021 Model Lightweight Brain waves signaled by cat's ear movement and voice - NeuroSky MindWave Mobile 2: Brainwave Starter Kit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/394941526-necomimi-2021-model-lightweight-brain-waves-signaled-by-cats-ear](https://www.desertcart.pt/products/394941526-necomimi-2021-model-lightweight-brain-waves-signaled-by-cats-ear) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-19*
