What is the difference between ath-m50x and ath-m40x?

While the ATH-M50x ships with three cables, the ATH-M40x comes with two, and those are removable like the ATH-M50x. Isolation measurements aren’t different enough to justify picking either one over the other. These two look very similar, except in the treble where the ATH-M40x has more volume.

Is the Audio-Technica ath-m40x better than the m50x?

Audio-Technica’s ATH-M40x may receive a lesser model number than the M50x, but that doesn’t mean it’s a lesser headphone. The Audio-Technica ATH-M50x might be near the top of the wired headphone world, but the Audio-Technica ATH-M40x is no slouch either. As you can see, the frequency responses of both are pretty similar.

Are ath-m50x Good headphones?

In our initial review of the ATH-M50x, we said it’s like the Swiss Army Knife of headphones, and that still holds true today. A great pair of wired headphones for budding audio engineers and veterans. Once the best in the ATH-M line, the ATH-M50x is still a good choice for casual listening and recording audio.
