This should have said in the product listing that this product was for kids - not just stated on a sticker on the package (after my online purchase). I thought Active Noise Cancelling [ANC] WAS the concept of limiting the volume of static/background rubbish noise - but I was wrong. Also, I thought 89 dB was quite loud - in the outside real world. Again, I was wrong. So, this product is absolutely useless if you want to listen to music
