From my experience, Sennheiser is the best brand out there. I've mostly tried their cheaper products, but even those were delivering quality you'd expect from earbuds 3 times their price. It's your safest bet.
Sony is also a great brand though, from what I've known and tried, so it's not like you'll get a bad product in any case
I need some flawless ones too - and I know this is stupid but I want them to look cool too. Ugly skinny little wires that curl and look cheap are NAWT ok.
