Sony IER-EX15C Frequency Response (measured on a B&K 5128)
Click a line or a legend entry to highlight it. Click again to clear.Tap a legend entry to highlight its line. Tap again to clear.
Measured frequency response (dB relative) against the SoundGuys Headphone Preference Curve. When the measurement goes above the dashed line, that frequency is louder than our preference curve, and when it goes below: it's quieter. Use the curve for comparison purposes only, as your taste may vary.

The verdict
If you're looking for a standard set of earbuds that don't break the bank, the Sony IER-EX15C are a good buy for listening to music or podcasts. However, the cable's microphonics can affect the sound and microphone of the Sony IER-EX15C.
✓Liked: Small and discrete, Good sound for listening to podcasts, In-line controls
✕Could be better: Obvious microphonics while moving
