I would not worry about the "bass light" posts at all. That was just one guy who was being weird and trying to start a rumour.
As for cables, the best monoprice one is the "designed for mobile" one. DO NOT get the premium cable. That cable is huge and inflexible, and it will destroy your jack. I like to call that cable "Jack the ripper" as it rips up headphone jacks .
I think that coiled cable will wind up being a lot shorter than you expect as it's only 18 inches when relaxed. You will have to pull on the coils to lengthen it past that, and that's going to put tension on your jacks - which again, you don't want happening.
LOL I'll avoid Jack the ripper. It shows that coiled cable stretches to 5 feet in the description.
- Compact 19 inch coiled cable stretches to 5 feet (60 in.)
