For me, that's not a problem. You get two pairs of three different-size silicon earbuds, the rubbery kind. Though I prefer foam tips, the medium size fit quite well, passively blocking ambient noise (by 90 percent, according to Creative) and delivering clean, balanced sound. Indeed, the high-end sounds come through crystal clear. The Aurvanas have a frequency response of 20Hz to 20kHz and a sensitivity of 115dB and 20dB at noise blocking. Bass is surprisingly solid (for this listener anyway), and overall performance is good, or as good as a pair of $110 Shure E2Cs, which are bulkier than the Aurvanas. While we prefer the sound of the Shure E3cs, the Aurvanas cost half as much.It all comes down to comfort and sound, and the Aurvanas rock if you don't mind spending a C-note for your headphones. The 4-foot cable doesn't easily get tangled and the earbuds are so light that you can let one hang out of your ear if you need to monitor the outside world. They match up quite nicely with the Zen Vision:M or Zen V Plus. In this price range, we also like the Ultimate Ears Super fi 3 Studio, which stay securely attached to your ears.
The Aurvanas include a Y-junction slider for optimal cable management, and they ship with the mentioned earbuds, an airplane adapter, an ear-gunk cleaning tool, and a travel case.
