HP has pimped up its Envy 14 and Envy 17 notebooks by throwing in Beats Audio technology and 3D features.

The HP Envy 14 Beats Edition adds the sound technology, which was formed by HP, Dr. Dre, and chairman of Interscope Geffen A&M Records Jimmy Lovine, to "offer power and performance along with state-of-the-art audio technology making it ideal for serious work and serious fun".

The special edition notebook will now be shipped with some Beats Solo headphones from Monster.

The notebook, which features a black and red design with a red backlit keyboard comes with Adobe Photoshop Elements 8 and Adobe Premiere Elements 8 built in.

It is an Intel Core machine with ATI Mobility Radeon HD(1) 5650 graphics and 1GB of dedicated memory.

The HP Envy 17 with 3D also has the Beats Audio tech on board, and claims to offer the "best stereoscopic 3D visual experience without compromising 2D content".

It comes with HP active shutter glasses and you'll be able to watch full 1080p 3D video via the 17.3-inch HP 3D Ultra BrightView display.

The HP Envy 17 with 3D boasts quad-core Intel chips as well as ATI Mobility Radeon HD 5850 discrete graphics and up to 2TB of storage.

The souped up Envy machines will be available from October. The Envy 14 Beats Edition has an RRP of £1339 and the HP Envy 17 with 3D should cost around £1559.
