2, Sony WH 1000XM4 parameters 3, Sony WH 1000XM4 evaluation # First of all, I bought it for the quality of Sony, the noise reduction effect is really good, and it is very comfortable to wear on my head. I won't feel very tired if I stay for a long time. You get what you pay.
# The sound quality is very good, in one word: Ness, the sound quality is like listening to a concert; There is nothing to say about noise reduction. After wearing it, the whole world is my feeling, and I can hear the voice from my heart. Ever since I took the subway and listened to songs with headphones on, I often missed my station.
# Noise reduction is not bad, and the experience in the subway is very good. But it is easy to sweat, and I feel a little stressed for more than an hour. The overall experience is not bad.
