Verdict

The Audio-Technica ATH-C505i is a budget-friendly, wired inner-ear headphone featuring large 15mm drivers and a 'Bass Dimension Exciter' specifically designed to deliver deep, expressive low-end performance. Its key technical specifications include a frequency response of 20–20,000 Hz, a low 16-ohm impedance for easy driving by mobile devices, and a sensitivity of 102 dB/mW. Main pros include its extremely lightweight 5g design, a gold-plated 3.5mm L-type connector, and a built-in condenser microphone with a three-button in-line remote optimized for Apple iOS devices to control volume and playback. However, notable cons include a lack of active noise cancellation, a non-detachable 1.2m cable, and a fit that provides minimal passive noise isolation compared to silicone-tipped in-ear monitors.
