The Monster Beats by Dr. Dre headphones, widely popular with hip-hop, urban and top 40 music listeners but sometimes derided as overly bass-heavy by critics, are expanding the lineup beyond other celebrity-designed earphones to an entire new line aimed at an older and more business-oriented demographic with the new, brushed-metal-finish Executive line. The new headphones offer a brushed-metal styling and auto-shutoff when idle.
