Kiwi Ears Aether 15.3mm Large Planar Driver IEM in Ear Monitor

Be the first to review this product...

:The Aether utilizes the largest IEM planar driver that we have created so far. With a 15.3mm diaphragm and extremely powerful, multi-layered N52 neodymium magnets, the Aethers driver outputs a truly headphone-like sound. Compared to the typical 12mm or 14mm diaphragm size found in other planar driver IEMs, the Aethers 15mm driver produces greater output at lower distortions, significantly improving the audio quality.; - :The larger driver in the Aether not only improves its resolution, but it also delivers a wider and more accurate soundstage and imaging. Thanks to our new chamber design and improved ventilation in the driver and shell, we aimed to reproduce the experience of listening to open-back headphones or stereo sound systems. And with the airy texture characteristic of planar magnetic drivers, the Aether sounds open and life-like.; :Tonal integrity was a key feature in engineering the Aether. Staying true to Kiwi Ears signature tonal balance, the Aether has been meticulously engineered to deliver a natural and precise sound. The bass is focused with sub-woofer-like slam and a mild mid-bass to mids transition to give a slight warmth to the body of the sound. The core midrange from 300 to 800Hz is flat to give a monitor-like accuracy to instruments and vocals. The treble was painstakingly tuned to carefully match the tonal perception of the human ear
