[Q]: I've had this product about 5 months and it already has problems. I run maybe 3 times a week's and the left earphone makes static noise now. I thought these were sweat resistant.
[A]: 1

[Q]: A little instructions would help. Initially I added the plastic tip in the back. No go. Finally tried on front and they flew better. Go a good 20 feet before going to ground. But perfect distance for little ones These were bought for our Twp kid fest this weekend. I am sure the little ones will love getting these. For the price it's perfect
[A]: 5

[Q]: These are nice sheets, They washed well and didn't really look wrinkled after drying but they do wrinkle once used on the bed like most other sheets. Still a nice set they are soft and have a nice feel to them. They fit my foam mattress good without slipping off. Would recommend.
