"For the price these are better than OEM"5.0 starson by Eat_a_Phukhole
Pros: Considering these may be the lowest price OEM replacement buds you can buy, they kick butt over my $50 Skulls. So if you are not requiring audiophile quality (like at the gym), save your coins and buy these!
Cons: Well, they are $20. So there are some bass and noise cancelling features that are not there. I do enjoy having these features.
Summary: Fact: Best I have heard for OEM replacement and the price is the best also. Since I am tired of losing $80-150 buds monthly, I use these for all activities (gym, snowboarding etc.). Gifts - even better, I know my friends and family will like the sound and it does not break the bank.
