I stuff 808’s , less than a tenner , and more bass than my CX299
Not the thickest of wire from where they split so be a little bit careful
In a 3 way test , Ipod + Walkman + laptop , with 2 listeners the 808 sounded better .
However , the Sony ones that came with my walkman did sound excellant , but I cannot compare as they died before the Istuff ones arrived .
And i dont know the number as i didnt write it down
Ink’d from Skull Candy alledgedly good in the pb that you are looking at .
I bought some CX300 on eBay , that were proper rubbish , so bad in fact i took a 3lb club hammer to them approx 10mins after opening the packaging
