Got about 30 hours on these now. Bought for the princely sum of £12.
I bought these for casual listening in the offices (podcasts and whatnot). so comfort/convenience was key. They have exceeded my expectations by some margin.
Their bass is their weak/strong point depending on your point of view.
For the consumer it is designed for it has plenty of bass. - Win.
For more critical listening, the bass is too flabby, bass notes can bleed into one...
