not unless they are defective, in which case you should return the headphone. The only "mainstream" headphones wrto which you may find the T1 lacking in detail and soundstage are the HD800. Forget the pink noise, if your drivers are brand new, let some bass-heavy music play on a loop for a day or two. It won't add any to soundstage but should loosen up the drivers a bit and improve bass detail.
