I bought mine about a year and a half ago.
I'm a very careful user. eg my ipod (5 years old) doesn't have a scratch on it.
After 1 year the "gold" cover on the back side of one side fell down, I could see how bad the glue was.
Few weeks ago the left earphone stopped working! I contacted Marshall but all they said was that it is out of Warranty and I can pay for repair in a local store or get new earphones. BAD SERVICE for really CHEAP BAD EARPHONES.
I'm still going to use their amps, but their earphones are highly overrated.
Really cheap design (although it looks pretty decent in the pics).
Regarding the sound- it is not much better than any other Earbuds, but once you find the correct size of the top of the earphone (that goes to the top part of your ear) you can easily use it. before hand it's just really painful.
I wouldn't recommend any of my mates to buy those.
The day I received these I had to send them back because a pair of sennheiser earphones that cost £20 beat them on every level. I was so angry. I noticed how bad they were when I listened to 'Clique' by Kanye and a few others and as bass comes in it totally distorts it. It was like listening to a very old radio try and handle bass. So dissappointed and I'm definitely not going to buy Marshall again.
