Linum Bax cables cost more than a new set of SE215.....not a great match...if you can afford Linum Bax cables you are not buying bottom of the range Shures. And while the manufacturer boasts of their pull strength it is irrelevant. IEM cables don't fail by snapping in half like frayed string or over cooked spaghetti, they fail at the joins to the earphones and at the jack, or because the cable outers perish or get damaged.
For a cable 120-160cm long you don't need anything special, just reasonable construction and materials. If a 160cm cable makes a difference to the sound with stock cable (either audible or measurable) then it signifies defective design/manufacture, or damage.
