These Beats by Dr. Dre Solo HD Headphones drops from $199.99 to $149.99 with free shipping at RadioShack.com. This is the best price we could find for them by $50 (Amazon has the White model for the same price but only with 17 left in stock). They have passive noise-cancellation to block outside sounds and come with a removable headphone cord with an in-line ControlTalk remote and microphone compatible with iPods, iPhones, and iPads. Only the Red, Black and White models are at the quoted price and available for shipping. Sales tax is not charged in most states.
