These are the ONES

I wanted to replace the OEM earbuds with something 'great'. I read the reviews and decided upon the E2C for several reasons. The first being "Isolation" earbuds - these are simply ear plugs that allow a sound tube to go into your ear. They block out other sound and allow the music to enter your ear. This results in turning the volume DOWN on my MP3 player rather than UP to compete with surrounding noise. This is important while flying. They come with an 'assortment' of rubber and foam earpieces to fit YOUR ear - 18 different units to be exact. I have a MEDIUM in my left ear and a LARGE in my right ear. The fit is PERFECT and I can go ALL day or ALL night without discomfort. The cord thickness is the first indicator that this is not your usual ear bud. It's thick and feels 'better' than OEM stuff. Once you have a GOOD fit, the sound will be incredible AND the sound isolation will be noticeable. I haven't tried working out with these things in yet, but I DID build about 30 feet of wooden fence with them in and they never came out - I think the workout will be a piece of cake. The cord is long and will most likely need to be put in your pocket. The carrying case is QUALITY but I don't use it because I always seem to have these things in at work or at home - NEVER in between because they WILL isolate surrounding sounds that you need to hear if you are driving!
