Good Ear Phones/Buds?

I own a pair of V-Moda Ear buds and they just don't seem to stay in, i have changed out all three sizes and still they just pop right out within mins i don't know if anyone has this problem with ear buds but any suggestions on some good sound quality ones that are affordable?

Almost anything made by Sennheiser.  This pair of headphones in particular, if you don't mind that they are not earbuds.

I have no experience with their earbuds, but these look pretty good.

Links are to Amazon, just to let you know.

After going through countless pairs of earbuds for my Ipod (default Ipod ones hurt my ears...) I've found that the cheap $20 Sony earbuds work the best.  Sound gets the job done, and they are durable.  If you cannot find earbuds that fit your ears, I know of at least one company (Skullcandy) that has a set of earbuds with moldable insets. 

Like SouldEdgeSlayer said, anything by Sennheiser  is a good purchase.

If you wouldn't mind them, the ones that actually stick into your ear work well and will never fall out because..well..they stick into your ear instead of just sit their a little bit inside.

Im just worried that they will fall out just like my V-Moda Bass Freq ones do even though they have interchangeable sizes maybe its the fact that they're

Go with Sony's earbuds for the cheapest. Best deal is Sennheiser's. If you got money to waste with a little above aveage that look cool, go with Skullcandy For sure!

I just bought a new pair, £14 off amazon, really good sound quality and stuff but whenever the wire gets a knock its applified in through the earbud. Its like sitting in a cave whilst its raining. I have absolutly no practical advice to help you avoid this....I even tried searching for other people who've had a similar problem, but i cant find anyone. So. I have now realised this post is useless to all.  

Anything Sennheiser, like the previous poster said.The moment I bought my first pair, I've only bought Sennheiser.

Zune Premium headphones are pretty much flawless.

I've been using Shure sound isolating earbuds for years. I just recently bought a replacement for my last set and got the SE-210's. A little expensive at $159, but comfortable and very high quality if you can afford it. I think they can be found on Amazon for around $110-$120.

Im currently using Skullcandy full metal jacket's, they're pretty good I have to say.
