233621 E300 Smart Noise Canceling Corfortable Music Earphone

I've got this little earbuds when I was in Hongkong two months ago.
Rumors came that the factory manufactures 233621 brand earphones and headphones is OEM factory which makes AKG earphones.
 
As an around $20 price range earbuds,this one has balanced sound performance,bass beats some of $60 to $90 earbuds, The midrange and treble sound good but not outstanding.
It looks like the item is ergonomic but I don't feel comfortable wearing it.
 
All in all,for an earbuds with $20,it works OK for enjoying  music and movie in mobile devices.
