Dell also sells Skullcandy headphones on their site. I did not know that Skullcandy was in laptops. Thanks for sharing. Info from two different sites below:
Audio and Speakers
2 Skullcandy Speakers with Waves MaxxAudio® 4 processing
Microphone – Integrated dual digital array
AND
Audio quality on the Inspiron 15R Special Edition and 17R Special Edition promises to be just as good as on the XPS 15, one of the best-sounding laptops we’ve ever reviewed. The notebooks feature Skullcandy speakers and Waves MaxxAudio 4 for fine-tuning the sound to your taste. The 17R Special Edition also features a built-in subwoofer. Media mavens can stream 1080p video and 5.1 surround sound wirelessly from the 15R and 17R using the notebooks’ built-in support for Intel Wireless Display, or plug their laptop into their home entertainment system directly using HDMI 1.4a output.
Sentiment: Strong Buy
