WH-1000XM4 Replacement Earpads Cushions, Protein Leather Ear Pads for Sony WH-1000XM4(WH1000XM4) Noise Canceling Headphones with High Density Memory Foam, Without Affecting Sensor (Black)

It completely blocks the sensor and makes it useless.

普通に使えてます。問題なし。 夏だとちょっと暑い。

No tuve ningún problema para instalarlas, y para quitar las originales, viene una herramienta que ayuda con eso. Muy buen producto.

After 3 years of solid wear of my MX4 the ears pads were looking gross. Very easy to install- simply use the enclosed tool to click out the old and then pop the new ones into place. Press firmly until you hear a click and they are done. Immediately I could tell there was a better seal around my ears as the noise cancelling went up a notch. The pads do have a cooling effect which will be nice when I wear them all day at work.

Its very comfortable but they interfere with the headphone's ability to detect a wearer. Sometimes you will wear the headphones and they will randomly shut off. If you disable the automatic shutoff feature be ready to have your headphones always on empty as you have to constantly put them on and check to make are they are off. More comfort for more headache. Value of this tradeoff is up to you.
