Sennheiser IE 300 Overview
Designed with audiophiles in mind, the black Sennheiser IE 300 In-Ear Monitoring Headphones feature a host of innovative acoustic technologies working together to deliver a nuanced and accurate listening experience wherever you go. Borrowing from Sennheiser’s IEM PRO professional line of earphones, the IE300 is built with rugged, compact, and lightweight chassis, making it durable, comfortable to wear, and easily portable for keeping up with your lifestyle on the move.
The compact housings are ultra-light (at 0.1 oz) and feature an ergonomic earmold design with a flat profile that provides a secure fit and comfort during extended use. The included memory-foam ear adapters add up to 26 dB of passive noise attenuation, keeping extraneous sounds out, reducing ear fatigue, and allowing you to focus on your music.
The 4.1′ detachable, para-aramid-reinforced cable with gold-plated MMCX connectors and 3.5mm TRS plug provides mechanical reliability for standard connection to digital audio players, headphone amp-DAC combos, laptops, mobile phones, audio interfaces, and more.
The IE 300 is supplied with three pairs of memory-foam ear adapters, three pairs of silicone ear adapters, a cleaning tool, and a compact hard-shell case.
Detailed Sound Everywhere You Go
The IE 300 is engineered with Extra Wide Band 7mm dynamic drivers that deliver pristine audio in a compact package. Single drivers mean that the frequency range does not have to be split up into frequency bands as with multi-driver earphones. Distortion, phase problems, and dissonances in the inner ear are greatly reduced (or eliminated), resulting in a harmonious and powerful sound.
A new blend of materials in the diaphragm improves its rest-and-response times, delivering tight transients and greater accuracy throughout the frequency spectrum.
An innovative miniature chamber-within-a-chamber called the back volume helps manage the flow of air behind the transducer. The direction and overall volume of air is controlled with precision as it travels through and exits the transducer system, delivering a discernibly more defined bass- and mid-range response.
A frequency absorbing resonator chamber was added to help reduce resonant frequencies that occurs in the ear canal when sealed with memory-foam adapters and bring back lost nuances.
The IE 300’s compact design permits a lightweight construction, which, thanks to the accompanying silicone and memory foam adapters, can be individually adjusted to fit you perfectly. Up to 26 dB of passive noise attenuation helps reduce ear fatigue and allows you to clearly hear your music without distracting ambient noise. This is achieved by using a pair of the included memory-foam ear adapters, which expand to perfectly fit your ear canal—ensuring perfect acoustic sealing with the added benefit of enhanced bass reproduction.
The IE 300 comes with a 4.1′ detachable Y-cable that features reinforced ear hooks. The para-aramid-reinforced cable is rated for thousands of bend cycles.
Gold-plated Fidelity+ MMCX connectors are seated each within a recessed, 4.8mm-wide socket beneath the housing’s surface, providing rotational durability and contact integrity.
