Hello everyone. I just bought audio technica m50x. I have fender rumble 15 v3 amp. When Im playing through the headphones it sounds much worse than on amp. I hear a hum, tones seems to be distorted. When I set volume on low its better. Is it a matter of setup ? Is it a good idea to buy external sound card and plug in the bass to the laptop ? Or maybe headphones amplifier ? What could help to achieve better sound while playing with the headphones ? Help guys, any suggestions ?
