To begin with, thank you to all the previous reviews that helped me make my decision. I was really pleased with my purchase that I will test with the children soon. Arrived on time, these two players and all their accessories are perfect and ideal for children 8 and 5 different sex (i did have batteries for remotes :-p). There are noisy indeed, but it should do so by car. I took two helmets in addition to personalize with stickers, more comfortable in my opinion that for small in-ear headphones. I hope to be happy with my investment in time ...
