Used Audio Technica ATH-CKP200 Earphones for $8

Speaking of not well-reviewed earphones, if you want an earphone as a low point benchmark to compare and contrast with other better/worse earphones, the Audio Technica ATH-CKP200 are getting destroyed in reviews, 11 of its 14 customer reviews are 1-stars. There is one unit available in the black color scheme in “Used – Like New” condition (damaged original packaging) going for $7.85 with free shipping for Prime members through Amazon Warehouse Deals

Again, this should only be of interest if you are looking for a bad earphone to compare and contrast with better models (or other under=performing models).
