Awesome noise isolation, wish I had discovered them sooner.,
This review is from: Comply Tx-100 Isolation PLUS Earphone Tips - (S/M/L) Black (Electronics)
I was about to buy a new set of earphones as I was down to my last 2 ear pieces. I wanted more isolation. Somehow I came across these, read the reviews and gave them a go.
I have tried them on the tube and on planes the isolation is brilliant. I use the large size isolation plus and find them as comfortable if not more so than the stock ear pieces that came with the ear phones.
One small negative, they do attract dirt like a lint roller. So unlike me keep them in a case or expect to spend more cas on replacements.
You do have to squidge them before placing them in your ear, but it takes a couple of seconds once u r use to it. Plus this is why they are so effective.
If you are an isolation freak like myself these are a must!
