I just got these for $25 at Wal-Mart. Jesus Christ, the bass is amazing and the quality overall is phenomenal.
Sound Quality: 9.5/10 - Songs are coming out clear as day, it's amazing.
Bass Quality: 9/10 - Testing it out on standard dubstep with no cracks, the bass is so real! Even some heavier bass dubstep isn't making the bass crack or bothering the quality.
Comfort: 10/10 - They fit perfectly in my ear without any annoyances. The plastic piece is flush with my ear and doesn't clip my hand when I brush my hand by my ear. Overall fantastic comfortable fit.
Cost: 10/10 - I cannot believe that I got these for only $25 at a store like Wal-Mart. It's amazing.
Durability: ??/10 - Just got them, but they appear to be as strong as the typical plastic earphones you see every day.
Features: 8/10 - Has the typical slider to adjust the fork. Included a adjustable length cord piece (Allows you to make the cord shorter so it isn't loose). Three sizes of earpieces.
Overall: 9.5/10 - Unless you're forking over the cash for something amazing, I highly recommend these for your everyday use. They're portable and have phenomenal sound with them.
Give me some songs with REALLY HEAVY bass. I want to see how far these things can go.
