While evaluating sound quality is largely a subjective task with measurements playing a supporting roll, determining how much isolation headphones provide can be done almost exclusively through measurement. Our web based graphing system can only display four products at a time so I'll show the results in two graphs. Fortunately that will also allow me to show some measurements of noise cancelling cans that weren't officially in this review as well. We'll start with the low performers. [caption id="" align="alignleft" width="298" caption="Some lower isolation noise cancelling headphones compared to the best which was the Bose QuietComfort 15."][/caption]At the bottom of the graph for reference is the Bose QuietComfort 15, which was most sucessful of all the noise cancelling headphones we tested at reducing low frequency outside noise. Among the Sennheisers higher in the graph (models we did not review for this article) are the Monster Beats by Dr. Dre, which delivered the poorest isolation performance of the bunch we tested. It also turned out to be one of our favorites ... we'll talk about that later.
