Recently bought the 560s and have been super pleased except for a couple of things. I use them for music, movies, and PC gaming. When gaming (CoD: Vanguard), the sound will occasionally fade out (not completely) for a couple of seconds then back to normal. Sometimes with a soft squeaky/static sound in one or both sides. It is hooked up to my computer through a DAC which is more than powerful enough to drive it. Has anyone had this issue with this headphone or any other Sennheiser? This is my first step into the audiophile arena. Wasn't sure if this was normal or could it be the game? I have only noticed it when gaming, but I also spend more time doing that.
ThrowscoachMight be your DAC if it is powered by USB interface. I had same problem with a dongle USB DAC. When I switched to a different DAC with its own power supply them problem was gone.
ThrowscoachThat random sound fade, I had my HD560s arrive today, 1H into breaking them in I noticed it did that once. As for that soft squeaky/static sound you have without hearing it myself could be anything from failure to just hair rubbing on the earpad.
DamienREasy thing to double check: make sure the removable cable is snuggly plugged into the headphone jack of the computer, and twisted to lock into place in the headphone’s earcup itself.
side note: the PC38X’s cable fits into the HD 560S even though it’s too thin for the twist and lock feature… but I like locking it and knowing I didn’t tug it loose with a cable snag.
