Are you serious? Think about it.

forgive my ignorance then, what do they have to gain? sites such as Headroom
have a generous return policy so it would not be to prevent returns would it?
I read that return rates on headphones is less than .5%

I hate to assume malice, but if you get a new pair of phones that cost you hundreds of dollars, and you're not immediately over the moon for them as we humans tend to not be with a new signature, especially if they cost what you perceive to be a good deal of money, are you more or less likely to bad-mouth or return them if you're told you need to give them a LOT of time before they'll sound good?

If you want to know whether they're any more informed than you or I, email them and ask them for the results of whatever tests they ran to confirm that their phones' sigs change over time.

And note: I'm not saying "burn-in" is or isn't "real" here- a quick search will reveal how the issue stands at this point.

Good idea. I would LOVE to get some real data on this subject- it would cut out a lot of arguing.

You realize you're not the first to email them (and a couple other companies, iirc), right?

 

[dw6928]

I will use my Ivy League English degrees to dazzle them.

Going by their measured frequency response, the eH350s should be anything but boomy - have them on a very high-impedance output by any chance?

 

[dw6928]

Headroom Microdac--->Heed Canamp to EH350 for its alleged burn in.

 

[dw6928]

after 24 hours, no changes of any consequence. one more day and they are
going UPS to Dad.

One thing is doubting "amp burn in" or even "source burn in", but doubting speaker/headphone burn in is just...

Andrea, would you agree that certain types of headphones might be more
likely to benefit from burning in? 701s for example, after numerous hours, changed dramatically for the better (to me). These less expensive Senns
have not changed much at all.

 

[rodbac]

I realize the question wasn't posed to me, but why would one headphone "burn in" more than another unless they're using dramatically different materials for the drivers?

 

[dw6928]

my impression was that the AKG drivers were dramatically different and that
is why that particular headphone has been singled out for the long burn in AKG,
Headroom and forum members suggest. I know you feel otherwise, but I really
noticed salient changes over the 500 hrs I let them run. My ears or physical changes? We shall see if AKG chooses to document it after they get my email
