Koss claims the new PLUG earbuds, while being priced at only $15, delivers same isolation found in more expensive competing products. Made of soft hydrophillic, formed urethane foam cushion that expands to custom fit the ear which improves isolation. Besides one-size-fits-all design, The Plug has an impressive frequency coverage ranging from 10Hz to 20kHz with sensitivity at 112dB SPL/1mW. I would not expect heaven from a $15 earphone, but it seems that Koss is trying to deliver a product that might just stand out. For the sake of it, I am placing an order to see if said 10Hz - 20000Hz is for real.
