Audeze is proud to introduce to the world of SINE, our new SINE DX! We have been showing prototypes of this headphone at Head-Fi meets and at CanJam and the response has been very positive. Here you go, the on-ear Sine DX with drivers optimized for an open-back headphone offers an amazingly smooth frequency response, an enormous open soundstage, and fatigue free listening. This Audeze.com exclusive offer starts Tuesday, April 25th at 12 Noon PDT. For this special promotion, take advantage of a $499 discounted price from the list price of $599. We have a limited run of 80 units, so we hope those who can "grab it before it’s gone" enjoy it as much as we do! More information is available on our website here.
