They are fantastic...i had one set for 2 years,but due to heavy use one of the speakers went.....i brought another of the same pair the next day....ive had these pair for over a year now and they are still going strong.
The sound quality from them is realy good for a £15 set,and because they are padded they are nice to wear.
They was £19.99 when i got them.
when my current ones fail again..il buy another set again,2 year life span for £15 is good imo.
