I am a hearty fan of the Monster Turbine, a great-sounding earphone from the cable giant. Monster say the Turbine Pro will deliver a few things to their already great formula including: a better cable (needed), driver, and higher quality parts. I say bring it on. Look for pre order of the the Turbine Pro in early October.
If you want to check out the headphone Monster will be one-upping, take a look at my Monster Turbine review.
