Query: Sony MDR-E828LP Ear Bud Headphones GREAT BUY!

The headphones were shipped super fast. So far, the ear buds work great. Good sound quality, comfortable, and most importantly INEXPENSIVE! Sounds better than the more expensive headphones I have used in the past. The convenient winding protective case is a huge plus. Highly recommended!!
