At Car Toys, search for "PowerBeats" to find the Beats by Dr. Dre Powerbeats In-Ear Headphones in Black, model no. DREPOWERB, or White, model no. DREPOWERW, for $104.96 with free shipping. That's $15 under our Black Friday mention from last year and the best price we've seen for these earphones. (It's also a current low for any color by $15.) They feature a built-in subwoofer and midrange tweeter, passive sound isolation, and ControlTalk in-line mic and remote.
Note: It's not guaranteed for delivery by Christmas.
