Wire gauge is a measure of thickness, the lower the number the thicker the wire, OCC is Ohno Continuous Cast which is the best type of copper.
Personally I wouldn't 24 gauge for an IEM as it is heavier and less flexible than the standard 26, and you will pay more for the inconvence
that really depends cyro treated cables can have excellent flexibility, the dhc sybiote cables are 24awg and from what ive read they have excellent flexability from cyro treatment. i will let you know wghen i get mine on friday. ive owned cables for the se535 down to 22awg solid core multi stranded pure silver, it wasnt all that bad flexability meh not so much.. but sound was amazing
What do you mean?
