A key element of the IE 300's balanced acoustical performance is the back volume - a miniature room-within-a-room that helps manage the flow of air. The direction and overall volume of air is controlled with precision as it travels through and exits the acoustical system. Further, a frequency absorbing resonator chamber was applied to overcome masking effects that regularly occurs in the ear canal, unearthing nuanced audio details previously buried in the source signal.
It's All About Connection
Sennheiser's engineers were tasked with delivering peerless sound AND dependability. They started with ultra-durable gold-plated Fidelity + MMCX cable connectors and seated each within a recessed, 4.8mm-wide socket for outstanding strain relief. The para-aramid reinforced cable is rated for thousands of bend cycles, adding exceptional durability to the overall listening experience. Included are (3) sizes of silicon ear tips and (3) sizes of memory foam tips to conform to the unique shape of your ear canal, maximizing noise isolation.
