●【Brand New】Noise Reduction Earmuffs - Blue, Foldable For Children / For Sensitive Hearing, Autism, and Concentration Thank you for viewing. This is a **brand new, unused noise reduction earmuff (blue / foldable)**. Only the appearance has been checked, and it has never been worn. ✔️ Target age: 3 to 16 years old ✔️ Noise reduction rating (SNR): 25dB ✔️ Folds up for compact storage ✔️ Recommended for supporting concentration during study, and for children with sensitive hearing or autism. ● The size is suitable for women with smaller heads (personal opinion). ● If you are concerned about the pressure, you can try widening it slightly by inserting cushions, etc., for a few days, which may alleviate the pressure (this is also a personal opinion). ● I personally felt that the silver part that adjusts the size (length) was looser than other products. However, it doesn't slip when placed on the ears, so I think it's easy to adjust. This is just a personal opinion. ●【About Shipping】 To keep the price as low as possible, it will be shipped without the box, with only the main unit. Please be aware of this. Please feel free to ask if you have any questions. Thank you.
