Today only, Groupon offers these Skullcandy 2XL Groove Hanger Headphones for $8 with free shipping. That's the lowest total price we could find by $4, excluding the deals below. (We saw them for $2 less in July, since expired). They feature 13.5mm drivers and a frequency response of 20Hz to 20kHz. The credit expires December 9. Although it's listed under Columbus, GA, this deal is available to everyone.

Of note, Amazon Prime members can get these earbuds in Pink for $6.81, or Red/White/Green for $7.38, both with free shipping. However, stock is quite limited.
