Ok so I will say I am a bit of an audiophile so some of the other customer reviews worried me. I tend to get higher grade earbuds so I get better sound all around. I have had Shure e-series headsets from church worship/monitoring. I mainly use my Etymotic er4 and er6 headsets for personal listening to my players and laptops. Either way when I got my Voyager I did feel the same lack of fit and lack of sound isolation others mentioned even with the smallest eargel (I have small ear canals). Well all etymotic earbuds come with a great variety of sizes and designs and for me I went ahead and pulled out the etymotics smallest 2 flange ear gels and with some coaxing was able to get them over the outputs of the Voyager. What I have now is a headset which sits great, feels great, and most importantly SOUNDS great. Sound isolation is creepy. I almost get the same silence I feel when wearing my etymotic er4s.
