Shure SE215 break in period?? - Page 2

post #16 of 23

It is generally accepted that balanced armature drivers (which Shure, Westone, Etymotic, etc IEMs use) do not need any break-in/burn-in.

 

Dynamic drivers (Sennheiser, RE0, lots others) DO need break-in/burn-in time for the speaker cone, however small, to get used to moving (think of a big speaker cone).

 

ALL IEMs need "brain" break-in/burn-in time -- that is, your brain getting used to a new sound signature and accepting it (or not) as "normal" sound.

i thought the SE215s were Dynamic drivers?

correct, 215 are dynamic whereas AFAIK other SE series Shures are BA

I went through a similar experience with my Grado SR-225i's which was more subtle.
 

 

It's a parallel process I think, both sides are important.

As long as people's suggestions for burning-in are kept within reasonable lengths of time, say 2 to 10 hrs, there's no harm done playing some pink noise moderately loud. It is when people start talking about 100-300 hrs as was/ is the case with the IE8s or over 500 hrs for the HD650s, where things just get absolutely ridiculous.

 

Most people seem to ignore the effects of psycho-acoustics (or brain burn-in) and the fact that we don't always hear things the same way even with gear we've had for a long time, much like the food we eat or beers/ wines/ juices we drink, which don't always seem to have the same taste. By this I mean that even today there are times when I find my ES3Xs (with over 1000 hrs on them) to be simply amazing, out of this world, and others when they sound just 'very good', ie I'm not always equally 'music hungry'. When I am 'music hungry' all my IEMs sound better, not necessarily great, but definitely better. There are other variables to take into account but won't go into them (again).

I hate to be a thread cheerleader, but I think that is one of my favorite phrases I've heard in a long time!  RAH-RAH-RAH!!!  ksc75smile.gif

Oh I know this is quite a late reply but I thought I should anyway post this as this ay help many others looking for a proper burn in technique which is actually helpful and not damaging!

I have tried this link to burn in two Headphones of mine and they have turned out to become much better with this. I personally play this playlist on the burn in player for 4-5 hours each day and make sure that it doesn't go more than that. I am sure you will love the results too........ http://www.tekfusiontechnologies.com/burn-in/

Hope I helped..... Don't forget to hit the Thanks button!!
