Monster has added new earphones to its headphone lineup called Turbine PRO In-Ear Speakers. According to Monster, the Turbine PRO is the first in-ear headphone to deliver reference-quality sound that meets the demands of music pros and audiophiles. The main features of the new headphone are speaker design with low mass and ultra-wide bandwidth for superior accuracy, all-metal construction to cancel unwanted resonance, Pro Sound Supertip for maximum sound isolation and MicroStrand conductors with ultra-low impedance for subtle detail and clear audio reproduction. The suggested retail price for the new Turbine PRO is $299.95, but the headphones are already available on Amazon for $249.95.
