Static & abnormal sound from Sony MDR-XB550AP headphones.

May 26, 2018
Hello. I purchased the Sony MDR-XB550AP from Wal-Mart earlier & I'm having an issue with the sound when plugged into the front headphone jack of my computer. There's static & the sound is muffled, but when I hold down the button where the microphone is located, the sound becomes normal like it should sound. Is this a well known issue with these specific model of headphones? I never had this problem when I used my Sony MDR-ZX110 headphones.The headphones do work perfectly when plugged into the rear headphone jack though, so maybe the front headphone jack just doesn't support 4-pole type headphones. That's my guess anyways. I contacted Sony, but didn't get a reply back yet. So if anyone could offer some solutions, that would be awesome. Thank you. (specs are listed down below in case you want them).

I should've mentioned this in the initial post (I'll edit in a sec), but the headphones work perfectly when plugged into the rear headphone jack of my motherboard. So maybe the front headphone jack doesn't support 4-pole headphones? I might have to get one of those adapters that have the microphone & audio ends that plug into the microphone & headphone jack, then has the female end that the headphones plug into. Like this?

That's my guess anyways

I think what isn't helping is that you're using headphone/mic combo that's designed for mobile phones if you read the specs on Sony's product page. It's that mic button & 4-pole jackplug that's a dead giveaway --- it's designed for mobile phones for sure.

Headset designed for a PC will have either separate jackplugs or a 3-pole combo jackplug.

It works on the rear headphone jack that's coming from my motherboard, but not on the front panel jack. I read online that I can get the adapter (like this --> OR an extender that supports 4-pole headsets. (like this -->
