These sit in the ear canal and block most of the outside noise allowing her to take advantage of her music and videos. Also, make sure youre using the best fit for your ears. There are some small flaws, but more often than not, they do not prevent me from enjoying the product. I thought it was maybe the battery since its wireless but its not. I?m really glad I did because they fit perfectly. Besides, in the old days, many connections had to be made for some devices while power is off -- luckily we have come quite far in technology (in some areas) ;)Overall - love it - super useful at to the reason we purchased it. I love the color, it makes the Bose much more attractive. I only paid $17. Sadly one didnt survive and these are my second pair but nevertheless, get them, wear them, love them! Quickly returned and bought another item.
