Decent Earbuds

These headphones are great for the money. The different earpieces really help with the comfort factor. The audio quality isn't like what you'll find in more expensive earbuds but if you're looking for earbuds with some actual bass and clarity for cheap, these are great.

Live up to their name

I'm not sure if Sonic will restock these, but if they do, these are a good pair of earbuds. I foolishly bought mine off of Amazon for about 40 bucks, but once i used them for a while, the bass really gets down. It is not overwhelming and if you tune your digital equalizer (itunes, ipod, whatever you use) to lower the highs a little and boost the bass, you can listen to anything from metal to dubstep. Very comfortable and blocks out lots of background noise, i often cannot hear much when on a crowded school bus let alone a couple of people in a room.
