I checked the straps after the first 200 miles and it needed no adjustments. I will probably buy them again which will be soon because this pair is nearly done. Worth the wait for sure! Very comfortable ???? The only downfall is that I asked for a size ?1 big kids? so he can use them for more time without his feet not fitting any more and they sent me a size ?13? toddler. She still leaves it behind places, but she able to find it quickly. I?ve even purchased 2 more as they?re good value just incase one gets damaged I previously had them stacked neatly in shoe boxes, it was annoying always having to pull from the middle box, and I was constantly having to mess with them. Fitting is awful. I need something that will feel comfortable and keep my breasts contained I am a DD. This headset is so cute, super comfortable, and a fantastic bargain.
