Asus launched its HP-100U personal Dolby home theater set today. Comprising a lab-tuned pair of headphones, a Xonar U1 external audio device and a high quality array microphone, the HP-100U makes up a complete audio solution for PC or Mac users.
The Asus HP-100U comes with the Xonar U1, an external audio device that harnesses the power of four major Dolby technologies to deliver high fidelity, interference-free PC audio. Furthermore, it supports DirectSound, EAX 2.0 and Open AL acceleration in Windows Vista / Windows XP and also on Mac platforms. The Xonar U1 is also equipped with a Hi-Fi headphone amplifier for improved clarity when driving headphones.
Asus aimes the HP-100U to notebook users. Especially Asus targets with the HP-100U Mac users, who have previously been starved of Dolby solutions due to compatibility issues.

The Asus HP-100U also comes with an advanced array microphone with noise-cancelling capabilities—perfect for crystal clear voice delivery over VoIP applications such as Skype, MSN Messenger and QQ, as well as during multiplayer gaming.

The Asus HP-100U Dolby headphone set comes in four colors. Asus has not published the pricing and release date yet.
