Review on Wholesale Bulk Hard Shell Plastic Carrying Case for Earbuds Headphones - Pack of 50, Suitable for iPhone, Android, MP3 Player - Black by Doug Knight

I use headphones in my class every year (for about 100 students) and this was a great inexpensive purchase. They're not fancy, but they do the job and I haven't had a single defective item. Having bought headphones in bulk over the past few years I can say that a carrying case makes a difference and makes it easier for students to manage them so they can keep them in their classroom and keep track of which belongs to whom. They lasted longer than other headphones.
