Hey, anyone have a link how to dissasemble Ultrasone HFI 580's and Pro 550's? Id like to make a small mod by sticking some sound dampening material on the baffle to maybe relax the treble just a tiny bit. Link would be appreciated.

Hey, someone in a past thread gave me a link to where I could pick up a pair of Ultrasone Pro 900's in the $300ish range online. The post seems to be MIA.....anyone know who might sell them in this pricerange? Looking for a pair thats in my budget.   Appreciated

Quote: The minute the enclosure is changed(in this case open from closed), the tuning is naturally changed.  

See, I love the Pro 550's, and the overall sound signature.......smooth from 20hz-20khz, would like to keep the overall sound signature............just curious if there is something out there that does just that, that might be even better overall.

Quote: Yes, I love deep articulate and accurate bass, but not at the cost of masking other frequency ranges. I also absolutely NEED smooth midrange and treble. My ears are overly sensitive to harsh treble and midrange that is too far forward/pronounced. The D5000 looks intriguing, but do...

Quote: I feel the opposite actually. The Pro 550's have actually more bass. The low frequency extension is greater and the mid bass is smoother(less hump). SInce there isnt as big a bass bump in the midrange alot more of the detail and articulation of the lower bass extension and...

Hey folks, already have a pair of HFI 580's and decided to grab a pair of the Pro versions since I found em new for $125 shipped which was a few bucks cheaper than the 580's I picked up. I am thoroughly impressed. Bass is actually smoother, goes deeper and is very articulate, while the midrange...

Quote: ANd what about the Pro 900? Im looking at doing either the Pro 550 or HFI 580 for good QUALITY BASS and natural extension for cheap money for everyday use and workouts, and possibly a Pro 900 in the near future.  

Personally the more and more I listen to my XB500's the less I like them. The Bass is OK, but its actually very muddy bass. The midrange and treble and poor as well. But for $50-60 bucks it is what it is. Still waiting to hear a pair of XB700's but for $90 bucks can you expect that much more...

Quote: Very different(As in TRUE night and day different)? Or subtly different(same basic "sound", just very small improvement/refinement in the quality of the sound)??     Im having a hard time believing 2 headphones with the same 50mm mylar driver, and basically the same closed...

Quote: I understand the differences of enclosure design and the effect on sound.    Lets use the HFI 580 and Pro 550 for example though. Same driver, impedance etc. Both are also closed designs. What is the difference in sound between the 2? Honestly I cant see anything more than a...

K, I got a few questions:   A. What is this Ultrasone Pro 650 everyone talks about? Their website only shows the Pro 550, 750, 900 and 2900. No 650.   B. People mention the 580,Pro 550, DJ1 etc.  Honestly dont they all sound identical? They use the exact same 50mm mylar driver/magnet...

Well, I just picked up a pair of the HFI-580's for $119 shipped. Hoping these are more of an "audiophile" headphone(ie: smooth midrange/treble)with solid real world bass performance. I picked up a pair of Sony XB500's a week back since I got em for only $40 shipped. With a lil EQing I love the...

Grabbing another pair of Sony XB headphones(Either xb700's or the xb1000's), hoping for some advice here:   . I already have a pair of Sony MDR XB500's. I do consider myself an audiophile(My main 2 channel home system features Kef XQ10's with a pair of 15" Rythmik subwoofers powered by a...
