    Detailed Sound Everywhere.

    The driving force of the IE 300 is a refined version of our Extra Wide Band (XWB) 7mm transducer, revered for its breathtaking acoustic performance in a deceptively compact package. A new blend of materials in the diaphragm improves its rest-and-response times for greater accuracy throughout the frequency spectrum. When resonances are minimized, the enhanced speed brings clarity to higher frequencies, subtly warm mids, and clean bass response with low harmonic distortion. Transients are tight without harsh frequency smearing, letting vocals retain their silky character directly from the master recording to your mind. The XWB transducers reproduce sound that is completely unique to the Sennheiser audiophile legacy—which is no surprise as they are developed and manufactured with exacting precision at our world-class facility in Germany. Although diminutive in size, its output sounds larger-than-life, offering intimate access to your favourite tracks.


    Air Traffic Control

    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.


    In-Ear Peace

    The IE 300 ensures that you can enjoy a thrilling hi-fi experience wherever you are. Imagine having a personal, expertly tuned listening room at your command - ready to provide sonic bliss at a moment's notice. Because the IE 300 shields you from ambient noise, your music stays in control of every listening session. The reduction of ambient noise diminishes ear-fatigue for better, longer listening sessions in practically any location you could dream up.

    Professionally inspired

    Included with the IE 300 are (3) sizes of silicone ear tips and (3) sizes of memory foam ear tips - the latter conform to the unique shape of your ear canal for maximum noise-isolating performance. In fact, the IE 300's design was inspired by performing musicians and their need for universal in-ear monitoring systems with an enduring, comfortable fit. Though you may never physically set foot on a live performance stage, your audiophile ear will appreciate the IE 300's ability to keep up with your lifestyle on the move.
