Review - Ultrasone PRO550 w/ PRO750 Pads and PRO900 Cable **Updated Feb. 10th, 2012** - Page 6

headphones pads / acoustic dampening (really tbh, serve the same purpose) does not account for burn-in in dynamic transducer in-ears, which totally eliminate the outer pinna thus headphones pads and the psychoacoustic effects of the pinna and head. the only factor is the placement of eartips within the earcanal (and earwax buildup) but really that can be easily notice via comfort issues / differences.

However the broader definition of burn-in as a change in earpad density can still be qualified as 'burn-in' in a sense because it's a change in state from the original. Also for it to be psychoacoustic such as a change in earpads / head positioning, one would have to notice the 'burn-in' every single time they put the headphone on, which just simply doesn't occur. There is no doubt that some claims of burn-in are due to other factors but to say all of them are is a stretch.

Moving the IE driver a millimeter within the ear canal will have a FAR FAR greater effect on the response you hear than any type of so called burn in.

But pads have nothing to do with the mechanical properties of the headphone driver itself - you would do just as well wearing them as earmuffs as opposed to listening to music to break them in: does anyone do that?

The fact that we don't notice burn in every time is further proof that changes are either not audible or a figure of the imagination. Headphones (speakers to a much greater extent) take a certain amount of time to reach operational temperature - why do we not hear this change every time we listen (or see it reported)?

As I have said before I wholeheartedly agree that burn-in, in the sense of phyiscal/mechanical changes in the driver does happen. But can this change alter a listeners complete perception of it's sound? Not likely. Does it take 300 hours of dedicated pink noise? Hell no.

only to the point where comfort issues will be noticeable:

More updated impressions:

There's no doubt about it; I really like these headphones. They feel more comfortable than my RX700s, they definitely sound better, and they continue to make music fun to listen to (just like the RX700s). Contrary to what I posted before, I now know what good sound stage should sound like, as well as what musical separation means. I've been listening to a somewhat muddied, veiled version of music.

The great thing is that I'm not even trying to find these differences anymore; they just make themselves obvious. In the beginning I was trying hard to look for differences between the PRO550 and RX700. I was being a bit overly analytical and was disappointed when I didn't perceive a huge difference. Eventually, I just decided to put on the PRO550s and listen to them for a long time (not burn-in long time, more like a few hours). Once in a while, it would hit me that a particular song sounded fuller; I could effortlessly hear details that I never really paid attention to because they were veiled and meshed into the background. At those instances, I would switch the headphones and listen to the song again through my old 'phones. Quite a noticeable difference!

I'm also happy about the bass in this headphone. It's weird to me to not have bass in music that incorporates it. It's what makes me bob my head and adds a fun factor.

The only knock I have against the PRO550s: the coiled cable they give you is annoying (and it's not that long). The straight cable they give you is like a yard long. I mean I know it's meant for MP3 players, but really? My RX700 has more than enough cable to travel from the back of the computer, around the desk, and still have slack to sit on the floor after I put it on my head.

I was really considering returning these headphones after the first hour of use. No longer the case.

Alright, I seem to have a 4 month update for you guys. Please see the original post for full details but it goes like this:

I've been debating getting some better pads or even getting an Ultrasone PRO900 for quite some time but was never able to justify the cost and couldn't ignore the fact that I actually like these headphones.

Last week I finally decided that I really don't need new headphones just yet so...this is the result:

Rally, have you found a difference using the 750 pads yet? I haven't found the 550 pads to be uncomfortable or warm but those gray pads are super sexy and completely change the look. I really like these headphones...would they be a good investment?

They're really nice pads. They're more comfortable than the stock pads and don't change the sound signature much at all. I don't think they sell these any more though since all the ones I see now on Ultrasone's online store are black.
