I got these for my 3 year old and although the age range is not clearly stated on the product page they fit him well. I should mention, though, that despite being a pretty average kid, he's always had a huge head for his age. Until they stopped measuring at age 2, his head was always at or near the 99th percentile. As such, they may not be suitable for the average 3 year old. They are definitely adjustable enough to grow with my little dude. They even fit my large adult head a bit when I tried them out to see what the sound quality and volume was like. The sound quality is surprisingly good for such a cheap item, and the best part is that the maximum volume is comfortable but not so loud as to cause any harm. My son is already a bit sensitive to loud music so he doesn't want to listen too loud, but I'm glad to know he can't accidentally crank the volume up. How it works is simple. Connecting with Bluetooth is easy and fast, and the connection is reliable even when you walk through different parts of the house. My wife and I work from home most of the time and our son only goes to daycare three days a week so having something like this that he can use while he is watching educational programs is very helpful when he is working at home when his grandparents can't help. In general, I definitely recommend it!
