Ive had this headphone and transmitter bundle for a couple of weeks now so I can review them having used them. Works well when new. I get about 3-4 months of usage out of them, at maybe an average of 90 hours a month. The sound quality is very good, but because of the short stand and how it sits close to a keyboard, it picks up nothing but the keyboard sounds. I didnt even like to drive in them. I needed new headphones. This are a tiny bit bigger than I expected, but it actually works in my favor because my son is growing like a weed! If you normally have a lot of smaller odd sized things you might consider buying some used suitcases at garage sales or flea markets and put the small and odd sized things in a suitcase for easier packing and tarping on the cargo rack. - Slip off easily if you bend over a bit. she LOVES hers too!
