As one of its daily deals, Best Buy offers the Sony Stereo Headphones in Red, model no. MDRZX100/RED, for $9.99. Opt for free in-store pickup to avoid the $2.99 shipping fee. That's tied with our mention from last summer as the lowest total price we've seen. (It's a current price low by $5.) They feature 30mm drivers and a frequency response of 12Hz to 22kHz.
