Sony zx2 and Sennheiser ie80 both have noise floor. What happened?

I used to use ie8, but now I use AKG k3003, both of which are 125dB. The latter has small impedance and slightly higher resolution due to the dual-unit drive.

Don't blindly listen to the hearing of others on the forum, everyone's ears are different. People with ears can hear some low noise when they pick up many portable devices. At present, the sound of iphone is the cleanest by comparison.

I haven't tried Sony e463, but the noise floor phenomenon you mentioned exists to some extent. Personally, I have two suggestions:

1, e463 is a good choice if the front end can only be set at three or four hundred. Who knows if there will be similar problems at the front end of the same price? Give up Sony no matter how high the budget is. Ie80 is biased towards natural sound, and Sony's heavy rendering itself is not very harmonious with headphones. If you don't dislike it, second-hand IPC will have a better performance in Bisogni.

2. If you enter e463 and there is really unbearable low noise, you can try to connect a longer extension line, or commonly known as the blocking line, which will be relieved.

Finally, I still want to say, classmate, you should exercise restraint. Your basin friend is really unkind. Giving you an ie80 is to encourage you to go to the point of no return. Playing photography is poor for three generations, and playing audio will ruin your life.
