EXTREMELY ABUSIVE BURN IN - poorly matched DT150 drivers bludgeoned into submission - Page 2

post #16 of 20

I have had two pairs of DT150 crossing my hands, they too sound a little different to one another.

I am weary of excessive volume for the break in. The tool I always recommend is the Isotek System Enhancer and Rejurvenation disc, does a fine job with no side effect I can detect.

Just keep the volume at reasonable level, if no haze somewhat below normal listening level. Isotek make it explicit that high volume would not speed up the task.

The disc includes a track for warming up the system each time before listening.

Any update on the Pro 900s?

....dt150 and ultrasone 900 was due. Both are simply superb.

Those dt150 are just so silky smooth but with a nuggety and deep tight lower frequency and bass response which makes other phones sound anaemic. No long term problems whatsoever from the brutal burn in.

The ultrasone pro900 are the the 'funnest' phones I have, with possibly even deeper bass than any beyer and a crazy holographic soundstage too boot. A heap of felt has cured a forward top end superbly. The shocking and ruthless burn in of three years ago has done nought to their longevity or ability...just made them better.

Standing 100% by this thread. Any time the drivers in my DT150s do anything dodgy (like crackles, reverb, etc) from being physically treated extremely badly I just blast the volume up for an hour, leave them, good as new.

 

If these aren't the best closed dynamic style headphone, I don't know what the world is coming to any more.
