Let"s be honest, most headphones are too big for children"s heads. That"s where our ACM-7002 stereo headphone for kids comes into play. The adjustable headband provides a perfect fit for a small head and the design is durable enough for the rough handling the young life brings. The ACM-7002 is just what any school needs. Each ear cup has a volume knob for individual level changing, which works great for numerous educational applications. The ACM-7002 works with mp3 players, the iPhone, any iPod, and most computers. While the headphone"s drivers are of impeccable quality, their sound maxes out at a level that is suitable for children"s ears. After all, they"re going to be using their ears for a lifetime, so why blow them out now.
