Those low end Sony earbuds are not bad in fact. They are really clean and clear. For under 50-60 bucks, e888 are well-worth the money. Some people are disappointed by the e888 because of the fitting issure. Thank god, my ears are big enough to put them in.
Long burn in period is kind of pain. But once you go through it, these phones rock!!!!
Seem you are looking for some earphones around 50 bucks. I also recommend the Audio Technica ATH-CM5 and Sennheiser MX550
