Sony MDR-XB700 rattling?!? GAHH, help?

post #1 of 18
Thread Starter 

So I purchased these from my local electronics store (price matched to amazon) after months of research...well they sounded great for about the first 3 hours, but now I get a faint (sometimes bad) crackling on vocals and some bass.....what's up with this? Will it go away after burning in? should I stick it out and see if it gets better? I have a 1yr warranty with free on-site replacement so waiting isn't an issue...

 

A little more info:

It happens mostly on punk rock type songs (e.g. Radio/Video - System of a Down)

I've reset my EQ on all devices (Laptop with a standard card, Droid X, and laptop hooked through a Sony iHome)

 

Should I return and pick up a pair better suited to my tastes in music? If so, what? Also these are sooo comfortable I'd hate to get rid of them x| lol

 

Any help is appreciated,

Karl E.

How loud were you playing them? I'd say just exchange them for another pair.. I'm listening to Radio/Video right now with my XB700s and I don't have problems.

When playing this do you get any pops at all or is it smooth bass? http://www.youtube.com/watch?v=PC7WEQsiz08&feature=related

I get pops periodically throughout it...Sorry, fairly new to this :\

Sounds like you're clipping the amp. Not enough power to drive the headphones to your listening levels. You may have damaged them already.

Terrible quality is what you're hearing! Download the Test Tone Generator and run a Bass Slide.

I get some random pops, but it just sounds like a terrible recording tbh.

 

I ran the Bass Slide and there were no issues

I'm getting the feeling my music is crap encoded....maybe? Says 320kb/s....My gf's assortment of Lady Gaga plays well? No crackle? It (says) 256kb/s.....Neither of our collections were ripped by us so not sure how to be sure?

 

Cracked open my actual CD - The Slip by NIN, those song also seem to play well (also 256, actually my rip)

Try what Graphicism recommended. If you're getting pops and w/e with the Bass Slide, exchange your headphones for another pair.

Wow! Thanks for the replies, installed the TTG and no pops/crackle on the 20-20k swap and bass slide, a lil noise but I'm 97% sure it's just vibrating my ear/hair. Guess it's shitty music :\ Thanks guys, looking forward to learning more :P

 

Ran a 1000 - 1 and back test and worked great? 



EDIT: Didn't see your message when I posted the one about music, sorry! :P

Funny seeing this thread here. Just today, I exchanged a pair of XB700s for a rattling problem.

I'm selling them to a coworker because I've only used them a handful of times in the 9 months that I've had them, but when he went to test drive them, he noticed a rather audible rattle coming from only the left side at certain frequencies and during certain tracks. Tapping a finger against the left earcup also resulted in the rattle, so we both figured that it was a loose wire or something that had come unglued, maybe resting against the inside the cup. We weren't about to open the headphones up to find out, since they were still under warranty, so we simply exchanged them. The new pair does not rattle.

BTW it might not be the driver itself but a loose plastic piece, check this pic but for me it only happened with boosted bass on the EQ. You can ofc easily fix it so it sticks in place and won't be able to rattle if that's the issue.

Alright, vibration seems to be gone, but in messing with the TTG I noticed what the sound is, it is a high pitched squeel that comes with any bass approx. 1 - 65hz.

 

It peaks every time the bass "peaks" (when it hits, as in slower at lower hz)? Am I just expecting too much out of a >$100 pair of headphones? Or is there a legitimate issue?

 

I think I'm goin to have them replace them, but they are out of stock atm and I don't want to wait for them to ship them to me. Will drive out to the other store and see if they can.

Driver probably defective, or something loose. Get it replaced.
