What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

EISA 2012-2013 Sennheiser HD 700




 Sennheiser has been at the forefront of headphone development for decades, experience reflected in the engineering of its new HD 700 model. Instantly recognisable by its elegant and very modern aesthetic, this open circumaural design incorporates a wealth of materials technology. The soft velour ear pads are supported on a silicone-damped headband while the efficiency of the internal drivers is enhanced by its ventilated magnet system. Very comfortable to wear, the HD 700 maintains Sennheiser’s tradition for a tremendously detailed performance, assisted here by its proprietary angled baffles. Moreover, this model’s sound possesses a welcome richness, its naturally warm aspect encouraging long spells of listening.
