I can attest to Senns taking a lot of burn in. My 595s took almost 300 hours before the bass really came out

I won't be able to give you specific times, but I can assure you that your cans will get better. Mine did. When I first took them out of the box, though not disappointed, I was certainly underwhelmed. They got better over the next 50 hours or so, and then seemed to deteriorate again until the next 50 (about 100 in total). From then onwards, they only got better, and at this point (250 hours) they sound divine.

This is coming from someone who did not believe in burn-in.


Edit: One piece of advice: try alternating between both bass-heavy music and pink/white noise. I found bass-heavy music did the most to open them up, while the pink/white noise combination seemed to 'refine' it. Of course, your mileage may vary.

burn in on cables?!

Hi!

Oh god. A good idea is put your HD650 in burn-in with WHITE NOISE for 2 or 3 days.

I make this with mine HD580 and the sound will be VERY VERY VERY VERY VERY VERY best than I loud without burn-in.

Thanks,

I just got an HD650 with the jr deal, and all of what everyone is describing happened to me too. It got to a point where I was ready to send them back. The first 50 hours or so, they sounded great. The bass was a little muddy, but it still sounded loads better than the bass out of my last set of cans, an HD497. Then sometime after 50, the bass completely vanished, and the treble was really harsh and annoying. It felt like I was listening to a grado

I was running them unamped out of the balanced outputs of an EMU 1212m, so i was afraid i damaged them by doing this. They sounded incredibly amazing though (first 50 hours), significantly better than a couple of low end single ended amps I tried. It looks like there's a fair amount of people running HD650's out of a DAC1, or the Lavry DAC, anyone else using a 1212m?

So with all the hype about burn in I pluged them in and walked away for another 50 hours. All of a sudden they sound good again, so i guess burn in is real... I just found this thred, so it's good to know this is a trend with sennheiser headphones, and that i didn't break my first $300 headphones.

While I don't have 650s, you might be able to accelerate the break-in process by playing loops of white and pink noise at an above average level, with a little extra bass. You can download the samples at my Break-in site below. (Look under Colors of Noise.) I find that dense noise samples like these work much faster than playing music through your phones.

I use iTunes, and play the samples day and night through my computer, and put the headphones in a drawer. The ocean-like sounds of noise are quite relaxing. I can't say when satisfactory break-in will occur for your phones, but at least you'll be listening to music faster.

Is this normal even after the 80 hours mark ? I searched and people say they lost the bass at around this point in the burn-in process. Also the treble should be severely rolled off. I really experience neither of this - are these headphones broken ? System used: RME digi 96/8 pad (blackgate mod) -> SDS Labs Headphone amp (other people use HD600 and such with this amp).

Mine got at about 10 days(running 24/7).

I can't understand what would come out from that, will the electrons start jumping around more even and easily after a while or what? (I can understand if the speaker membrans might "set themself" a little where they are mounter or lose up from the movements or whatever.)

Better take a high voltage power cable 10cm thick or so then, should have had a nice burn in... (Actually I saw some cut of in 10-20 metre lengths or so, considered taking two home for my speakers just to be an ass but I guessed they where quite heavy.)

Do you mean I should play these samples with "bass boost"? (ie. turning up low frequencies)

I compare them to my old 580 and I like more the latter. My 580 sound, at least much brighter, but I think bass is also better. It's really noticeable with any source. I hope burn-in is really physical, because if not, I will be really disappointed. vs

You'll be amazed.

I wouldn't do it. Though no one seems to know it anymore, patience used to be a virtue...

I just got my HD650 a week ago. I don't want them to play stuff, that I can't hear. I don't want them to be in a closet on our honeymoon. I don't want them to fool around without me!

You bumped an ancient thread to say that??

Again and again it's proved that burn-in is a nice tool to keep consumer from returning unliked headphones, etc...
