The Aonic 3 is a good sounding in-ear headphone from Shure with a comfortable 'over the ear' design and an excellent ratio between price and performance. In this Aonic 3, Shure applies a vented full-range Balanced Armature driver for crystal clear sound and deep bass. The frequency response ranges from 22Hz up to 18.5kHz, the impedance is 28 Ohm and the sensitivity is 108 dB SPL/mW. This makes this Aonic 3 perfect for use with a smartphone or digital music player. Due to the application of Sound Isolating technology, these in-ear headphones dampen the ambient noise by 37 decibels, so you'll enjoy your favourite music even more intensely than with the earbuds that were shipped with your smartphone. Designed for professional use, these in-ear monitors are built to last. The headphone cable has a length of 1.3 meters, is fitted with a 3.5mm jack plug and has MMCX connectors for easy replacement. The cable is equipped with a universal in-line remote (Android and iOS) and fitted with a built-in microphone. If you receive a phone call while on the road, you can answer it safely without touching your smartphone. For an optimal fit and long-lasting comfort, Shure supplies a Fix Kit with soft earplugs made from two different materials in the sizes-small, medium and large. When not in use, store your headphones safe and secure in the included hard case.
