While I haven't used this particular model, I am very familiar with the Sennheiser brand and the quality they tend to deliver, so at $12.99 + $5.00 shipping, these CX150 Noise Attenuating Earbuds qualify for the best deal of the day. The cheapest I could find a recent deal was $19.99 that expired in December, and now they are hovering in the $30 range on eBay. Rumor has it that Sennheiser discontinued this particular line, as the effectively undermined the margin of benefit to getting earbuds in the higher price range. At a minimum, for $18 total, it'll help drown out some of the annoyances while on MARTA in Atlanta and provide a backup pair of earbuds that fits any budget.
As all deals with Woot go, this will only be a valid price TODAY, 2/16, so head over to Sellout.Woot if you want to take advantage of this gadget deal of the day!
