Really dumb question. USB or 3.5mm audio jack headphones with built in DAC

post #1 of 5
Thread Starter 
Got a pair of Sony MDR-1ADAC, and getting the occasional static interference and quite frankly the audio quality isn't up to what I was expecting. Since the USB also acted as the charger for the headphones, I'd always just run the audio that way, but I'm wondering if I also connect the 3.5mm jack, swap the input over to the 3.5 on the headphones, if that would provide any real benefits over the USB 2.0 connection it's using now?

I'm assuming with the 3.5 I'll at least be able to use the realtek audio settings to tweak the base and get a little better audio out of it.

Or, did I just waste money on a garbage headphone setup?

I would assume that the 3.5 input bypasses the built in dac, so yeah, you could adjust audio settings through the realtek manager. The built in dac is likely better than the one on your motherboard though.

I'm a little confused - testing this is so easy, why ask the question? You can test it a lot faster than anyone can reply smile.gif

I'm actually very interested to know the outcome though, so I am glad you DID ask. Did the 3.5mm jack improve sound quality? Static is usually some kind of electrical interference (EMI), typically caused by things like fans and the overall electronics of your MB. USUALLY USB is BETTER than 3.5mm when plugged directly into your MB for this reason. However, it's not a law of physics or anything, so knowing that the MDR's USB may be awful is of interest.

Keep us posted on the result!

I'd try the 3.5mm jack, I've used portable speakers before (3.5mm jack and USB charging) and if I had them plugged in to a USB port on my PC to charge while in use I would get a lot of static. I found plugging the USB into a spare iPhone charger eliminated the static completely.

I was asking because I threw the original cord 3.5mm in the trash when I was cleaning up right after I got the headphones and my box of cords is in a storage container haha.

Did some digging around and finally found one and actually, at least in my opinion, the audio is way better through the 3.5mm jack running as a pair of speakers rather than through the usb cable.

Now to hunt down a 3.5mm that's long enough to actually use for more than 10 minutes of testing to see if it's just placebo or not.
