What are the differences between the Audio Technica ATH-M20X, M30X and M40X? Are there any major differences, or would the M20X do just as well?
Can you give me more details about the drivers?
The ATH-M20X has a 40 mm driver, while the M30X has a 40 mm driver with rare earth magnets and copper-clad aluminum wire voice coils. The M40X has a larger 45 mm driver with earth magnets and copper-clad aluminum wire voice coils, resulting in a wider frequency range.
