Is burn in real or placebo? - Page 10

post #136 of 461

Then how do you explain the big differences people heard when breaking in (about 100 to 300 h) the K701?

 

I know a few options that could explain what's going on, but driver burn-in is not one of them.

I bought a headset for my girlfriend as she had always wanted a nice gaming headset so I opted for the pc360. She put them on for 20mins came back and said I can't hear bass. I tried them on and noticed the bass was very light indeed. I took them home and used them for about a week probably 30 hours in total. I noticed a huge difference and bass really started to come through. I hadn't said anything about my findings or about burning in all I did was hand the pair back to her and said have another listen if you don't like them we will buy a different headset. She put them on turned and said wow were the other pair faulty?? The bass is awesome. She actually didn't think it was the same headset.

I just found after 30odd hours the headset balance had improved and bass had become more neutral vs light. For someone to think that it wasnt the same headset and it had been swapped there has to be some truth behind the burn in.

Day one everything seems OK. Nice sound - you are happy and excited. Day 2 the missus notices you are too happy which makes her suspicious. She finds you have a new toy. By the end of day three she has discovered the real cost and that you weren't straight with her the previous day and you are in big trouble. For a week or ten days she is unusually busy and you are eating frozen crap from the supermarket or toast and your love life is comparable to that of a celibate monk. The headphones are no fun and you dare not even use them so you burn them in. Somewhere between days 10 and 14 you have grovelled and apologised enough and really carefully hidden the receipts for the other stuff you bought. You are back to home cooking and no longer scared of waking up with a pillow clamped over your breathing apparatus. You now feel relaxed and the headphones sound great too. This is the secret of burn in. For single people it's mostly that they don't already have enough to worry about.

:-) day 1 bought her the headset she doesn't like it. Day 7 ask her to try it again before sending it back. She's had 7 days for her to think about it and come to the conclusion it was bought as a present maybe I shouldn't hurt his feelings and just pretend I like it. As she could see the excited look on my face and doesn't want to disappoint. That was the real burn in :-). Lol

I check my scientific horoscope daily to know what to think. It's obvious we are human and flawed so are not capable otherwise to trust our senses. Wait, aren't scientists human too? The whole world is placebo in art and fashion but science hasn't figured that one out yet. They are just eclectic and not to be given any credence because they don't fit a formula.

Since the field of science is black and white, let's see a top ten list of songs.

Snarky fun so don't get your slide rule in a twist. wink.gif

And how is this comical post related to this topic?

Everyone agrees that burn in is required for optimal sounding cans. That's how I would like it to end but of course there will be arguments and opinions thrown left right and in the end we wil all agree to disagree. THE END

Earpad compression, helps retain the sound pressure better.

That actually does make sense and might explain the difference in the bass quality. It's still only about a 4 week old headset and I can see slight compression of the ear pads versus brand new.

Levity? Cons and pros? What are you talking about?

One person disagreeing is enough to make your statement wrong. How do you define "optimal sounding"?

post #149 of 461
Knor you don't seem to have a sense of humour as every post is so serious and well straight. Optimal means most favourable or desirable btw. I was being sarcastic in the previous post not making a statement at all. :-) hence the humour comment no offence intended.

Hey guys!
I've been lurking for a while, but it seems this is the time for me to post.
I'm a professional audio engineer and system designer with a background in concert and recording audio along with experience in lighting and pro video engineering.

Now the pro audio section is quite a lot different from the HIFI world, (I'm a HIFI guy when not working), but the headphone burn-in topic has come up in discussion between some of my workmates and I in the past.
So about a year ago we had decided to test the whole burn-in topic and bought some basic Sony MDR-v6's and hooked them up to SMAART (an RTA anyalizer). The way we did this was to use two balanced Earthworks M-30 measurement mics, and a Sound Devices computer interface. We used some studio foam on each side, then stuck the mics into it at ear level, then played pink noise/white noise and recorded what we saw in SMAART. We ran them for around 20 hours between measurements and noticed a change ever so slightly over around 80 hours of burn in.

I won't go into exactly what frequencies were effected, however there was a clear change of 1-4 DB at many separate frequencies, which tells me that the drivers must have changed their response over time, along with their sensitivity at different frequencies.

I hope this helps!

Your friendly Audio dude
