I have no issues with the gain level or noise. Overall the sound quality as expected(good+). However I am having issues with the PC connection. Often it is just disconnects automatically, or makes a buzzing sound. Luckily, it has a power switch on the back and solves the issues. It is quiet annoying to reboot everyday. Once again no issues with the sound quality. I would love to give it a 5 star just cant justify.
