P.I.M.P (Pretty Intense Mogami Perfection)

 

Mogami 2893 (I friggin love that cable!) with bright red TechFlex, terminated with a Neutrik NP3XB. The other end will off course be terminated in Cardas Sennheiser plugs smily_headphones1.gif

I too have the HDP and It goes very well with the HD650. If I'm not listening to Jazz or acoustic music (Tube music) I use the HDP.

The Bose QC headphones are UNMATCHED for noise cancellation. I love mine for traveling on airplanes. When I travel on noisy airplanes (q400 commuter planes), I wear my Etymotic Research IEMs underneath them for higher fidelity and double noise attenuation.

They aren't audiophile headphones, but they do have their place in the market and are pleasant enough sounding from an iPod.

They have the benefit of switchable impedance for listening directly from portable devices or plugging into an amplified source. I wouldn't want them as my only pair, but they definitely have their place in my lifestyle.

Finally got home and started listening to it. Better than my beat up HD280s, and I can't really wait for it to really burn-in...

 

How long is the typical burn-in period? I've seen the number of 200-300 hours thrown around.

post #4085 of 36890

My take on that - the driver should arrive at its nominal state within a relatively short period, but it can take weeks of regular use for the ear pads to settle in to the shape of your head and become comfortable; that will bring the drivers at least a few mm closer to your ear and will help ensure the intended acoustic coupling, so expect some changes (concurrently with you getting used to their sound, too). Past that, "burn in" is just the driver kind of wearing as time goes by and isn't necessarily a predictable thing that's going to be the same for everybody. I remember my HD-650s seemed to settle in, talkin' bout earpads here, after about a month. And they've been a serious pleasure ever since.

 

200-300 hours, in my opinion, is crazy talk. If you had nothing but 20hz and ran 20hz for 10 hours that's 20 cycles per second times 60 times 60 times 10, or 720,000 extension/reflex cycles. And that's the lowest you can hear. Pink noise would have the highest potentially audible frequency represented in that same period 720,000,000 times. What do you think could possibly require billions of extension/reflex cycles to "settle in?"

 

For 300 hours, that's 21,600,000 at 20hz and 21,600,000,000 at 20khz. Something tells me that there's not a property that requires 21.6 billion times to show itself... Or 21.6 million, for that matter. Earpads, though, they wear in. It's a pleasant experience, getting used to the sound of the new headphone, having it start to fit you better and better... I say just enjoy it and don't worry about running the tiny drivers tens of millions to tens of billions of cycles smile.gif

I really want the HD650 for music and movies to avoid the neighbors from calling police, but I also would like the Bose QC15 for when I am mobile and just general noise blockage inside and outside. Is there a huge sound comparison with the HF650 and the Bose QC15? I cannot get both now, so its either one or the other.  What do you guy suggest. Try not to flame me too much since I am a noob here. Thank you.

 

Oh yea and why do they call headphones "CANS"

Response above. Sorry, tried to delete and don't know how...confused.gif

Good post. I don't recall noting significant changes with my HD650 with burn in. I don't doubt though that wear on the pads would result in my HD650 sounding slightly different to one straight out of the box. Just use them at safe levels and enjoy the music. If they sound better over time, whether due to physical or mental burn in, then it's a bonus.

 

post #4088 of 36890

Ha thanks. I'll just enjoy them. smily_headphones1.gif

post #4089 of 36890

I hope so, they really are a special headphone. Since prices came down I picked up all of the classic big 3 and some others too... The HD-650 are still my favorites. When I'm not listening to them, I'm enjoying different sounds, different feels, all that good stuff, but the HD-650s hold up extremely well. It's important to keep in mind Sennheiser move slow, but decisively - when they launched the HD-580, it blew folks' minds. A dynamic that competed with electrostatics and didn't require all sorts of crazy stuff to drive it and had really good bass... The HD-600 and HD-650 climb that ladder, well, I guess the 600 and the 650 are a bit more lateral, if you find in the fullness of experience you think the HD-650 have a bit much midbass and not enough treble, but that you really like their sound otherwise, the HD-600 are sort of opposite there, while staying very strongly in the same sonic idiom. You could probably find someone to trade HD-600s for HD-650s given the price difference and perception that they are sort of a side-grade. But if mine die for some reason, I'm getting another pair. Edit: Check this review of the HD-580s back in 1994 to get an idea of what I mean when I say Sennheiser moves slow but decisively... They changed the headphone world in important ways, kicked off the modern era of dynamics.

 

In fact, it's kept the HD-800 off my can investment radar since they're more like... AKG K701s on massive steroids; the Beyer Tesla T1 seem to be often described as HD-650s but better, and that would be the sound I'm after if I'm going to invest more than a grand in a single set of cans! Maybe the LCDs, they seem nice, but I have strong affection for Beyer after recent great experiences with their modern 250ohm drivers in the DT-770 and DT-990 pro headphones. They have some real mojo to 'em, although they don't make me like my HD-650s any less, haha. I don't know, I have a lot of faith in Sennheiser to make some impressive cans, but I've gained similar faith in Beyer. I guess I'll decide one of these days. biggrin.gif

 

Anyway, opinions differ, someone might well tell you that you need to run sorta-loud pink noise or bass-heavy music for a week before they touch your head! It's not my perspective but it is a perspective. Burn-in is controversial and probably always will be since there's no evidence that trumps "my ears hear different" to the person with the ears, you know? I try to allow for things I know to be true, like pad conformity and how that alters the acoustic coupling, but I do remain unconvinced regarding the drivers needing weeks and weeks. I do hope you love them, for two reasons - first, because they ain't cheap, and I'd hate you to have wasted money... Second, because having another HD-650 lover can't hurt! Maybe Sennheiser will put out an HD-700 that builds on the HD-650 sound, not such a departure. Or maybe that's wishful thinking.

WHOA, something just blew my mind.

 

I was listening to a classical piece with some trumpets which I've listened to multiple times before, but this time in a totally silent room and with my eyes closed. Suddenly I became aware of a clear but extremely silent sound in the background. As a trumpet solo was playing I was hearing the musician pressing the valves on the trumpet for each noteExtremely quiet, but definitely the sound of oiled metal / piston type sound corresponding to every new note of the trumped. Wow. I really like these headphones :) (I know this is probably detectable with others, but these are my first true high quality headphones, so it's amazing to me :D )

Nothing quite beats the "Wow, I've never heard THAT before"-feeling you get when suddenly picking up new things in a song. Try putting on Pink - "Glitter in the air" - you can clearly hear the pedals on the piano smily_headphones1.gif

Heh. Yep, the pedal on that song is really easy to hear with these. The trumped valve thing really impressed me a lot, because the "shhhh" sound of tiny little oiled pistons seem maybe 5-10x quieter than the piano pedal, yet still it's crystal clear :)

I do believe in burn-in, to some extent. My IEM's, Future Sonics Atrio M5 sounded horrible right out of the box, no better than the Skullcandy Titans I have tucked away as backup in my bag. No worries, I've read the thread here on Head-Fi about them needing burn-in, so I made an Mp3-file like this: 2 minutes of pink noise, 1 minute of silence, 2 minutes of brown noise, 1 minute of silence. Then I looped that file for 48 hours. Already after 8 hours, the flappy bass had cleared up massively, but the highs were still shrill and sibilant. At the 20 hour mark they started sounding pretty darn good, but I let them play for another 28 hours. After that, they just sounded GOOD. Tight, clean bass, lovely highs and a generally warm, musical sound. In a sense, the Atrio is like a HD650 IEM, but with punchier bass. They were in a drawer while burning in, so it wasn't just me getting used to their sound. 

 

The previous owner of my 650's had put a total of about 20 hours on them and they sounded really good when I got them. I tried feeding them my burn-in mix for 30 hours and absolutely nothing changed. They still sound great so now I just enjoy them, while waiting for them to settle into the shape of my noggin.

post #4094 of 36890

Would it be a waste of money for me if I was to buy these headphones for watching movies louder in my apartment so I can enjoy it better and for listening to other types of music such as rock, hip-hop, R&B, some Jazz and club music? I do not listen to classical music yet. So I want to make sure I purchase the right set of headphones.

post #4095 of 36890

Some may disagree, but I haven't found the thing HD-650s can't do. I can go straight from the Shatter OST (electronica) to Opeth to a string quartet to Netflix with the HD-650s and not be disappointed.
