If you are looking for some heavy bass on the go without having ginourmous headphone on, v-moda's Bass Freq earbuds may have what you are looking for. The Bass Freq earbuds are noise isolating and very bass-heavy earbuds designed to allow even the whitest of white guys to roll down the hood without being ashamed of listening to bass-heavy music.
They operate at a frequency of 8Hz to 22000Hz and can rock out 122dB at 20Hz. The fun doesn't end there, either. These earbuds are available in three different colors and the cable even includes on of those handy cable wraps.
