Shure SE846 Sound Isolation EarphonesIf you are looking at this item then you are probably at least somewhat familiar with high end audio equipment and nothing more needs to be said.  If you are not familiar with these earphones, I suggest you look through the  2 massive threads on head-hi.org and read through the 1000's of posts regarding this phenomenal set of earbuds.  Personally, I have never heard music sound so good in my life and I have owned several sets of high end in-ear monitors from makers such as Westone, Futuresonic, Etymotics and others.  There are really no words to do these things justice.  They simply have to be heard. I bought these new and use them about 14 or so hours a week at home in the evenings.  They are the most precious thing I own and have babied and pampered them.  In fact, I have never worn them outside.  They are truly the most remarkable thing I have ever owned.  Unfortunately, my new business needs the money more than I need to listen to luxury, high dollar audio equipment, but I assure you, they will be missed.  I just cannot say enough about them.These come packaged exactly as they came from the factory.  The only things missing is the pair of white triple flange tips (the ones I used) and the 60" set of cables. The 45" cables are included. I did not include the triple flange ear tips for obvious hygienic reasons.  My parrot bit the long cables and one side quit working.  Aside from these items, everything is included and packed exactly the same as I received them new.SE846 Sound Isolating Earphones feature a groundbreaking low-pass filter that
