General_WinterAlthough I do not think the XB50ap is on the same level (in terms of fidelity) as the X11i, I will say that for the $ the XB50ap is an awesome set of earbuds. I bought my brother a pair for Xmas a couple of years ago and he is still using them daily. Also, they will have way more bass then the X11i =). If you are in the market for a pair of headphones that sound like $75 earbuds and are bassheavy I recommend the XB50ap too.
WildMurphI'm not much of an audiophile using cheap headsets for the longest time, being an adult and desperate for a pair of headphones, i saw these on sale and brought em and they are really great, i would've thought this is something out of a $100+ headset, though the bass is the selling point it is still very much a very good pair of headsets, especially for the price
i got one from an airport kiosk of all places and they're really good for the price, especially the base
