I bought these to replace my Backbeat Fit 2100 headphones (which I always seem to carry in a different bag). The Fit 350's sound quality isn't as good as the 2100. The 350s reduce more ambient noise, but I prefer the 2100's ability to hear the outside world (especially since we often can't see their mouths moving in this bold new world We're in.) Unfortunately, I can't find THD or noise reduction specifications for either set on the product pages here. I hope Plantronics will share this information with us.
