Pros: There is a way around the plug problems
Cons: none to add
Summary: The problems with other MP3 players seem to be caused, as the editors say, by the fourth conductor area on the plug. This makes the headphones sensitive to exactly where the MP3 player has its ground connection contact.
If you really like the headphones (and for $179 you must or you would have returned them) you or a tech-savvy friend can make a short adapter cord which connects all but the mike channel to a standard 3 conductor plug. I don't know of any such adapters ready-made, but they might exist.
You won't see me wearing them, since I would end up with an ear infection even if I could tolerate the intrusive ear fit. But that is personal.
One other thing to keep in mind when comparing them to other options: noise isolating or noise blocking means it physically keeps the ambient noise out, while noise cancelling means that active electronics is used to generate a signal in the earphones that is the exact opposite of any leakage that comes around or through the earphone or earbud. Some product literature and even some reviews are not clear about what you are getting. Especially if a vague term like "noise reducing" is used.
