My almost 6 year old daughter is a headphone KILLER. More specifically, she has destroyed 3 different 3.5mm jacks trying to plug headphones into her iPad. We scored a nice pair of Batman bluetooth headphones for $10, those met an early demise during a tantrum. Her current headphones came from 5 Below, they have a removable 3.5mm cable. She just bent the tip off. I've got one cable left, then it'll be splicing two good ends together. Got me to thinking, why not get a bluetooth receiver with a 3.5 jack and strap it to the headphones. I see them for real cheap up to not so cheap. Anyone used a receiver like this? Any thoughts on them?
