The Logitech® Mobile Cordless Headset, a Gold IDEA 2003 winner, is a soft-touch headset that clips comfortably to your ear, and the noise-canceling miniboom microphone delivers great sound quality even in loud environments. And no cords means nothing hangs down from your ear and nothing gets in your way. The Cordless Headset works with the Ericsson HPB-10 phones: 2218Z, R300 series, R380, T28, T28Z, T60d and T68
