Two models are available, the Turbine Pro Copper and the Turbine Pro Gold. Both models are priced at £250 as standard or at £280 with the ControlTalk headphone cable for iPhone.
In the words of Monster, the Pro Copper version "provides unsurpassed accuracy over all audio frequencies for an ideal true-to-life professional reference listening experience".
The Pro Gold headphones meanwhile offer "a slightly pronounced low-frequency response, geared toward audiophile listeners who prefer punchy, impactful bass".
Both sets of earphones come with the rubber 'SuperTip' sound-isolating eartrips as well as some new SuperTips made specially from a foam material.
