Etymotic EB1 and EB15 noise cancelling earplugs

Etymotic has developed a pair of earplugs that protect your hearing against things like loud explosions and gunfire. The EB1 and EB15 Electronic Blast PLG Earplugs, retailing for $449 and $499, respectively, are aimed toward buyers such as hunters, musicians and soldiers -- folks who are exposed to loud noises and need protection. Hit read more for details.
The analog earpieces are powered by a 312 hearing-aid battery and will last three weeks. There's no on/off switch -- just a high and low gain control. High gain is used for environments that require an amplification and the opposite applies for low gain. In other words, if a soldier is out on the battlefield and needs to hear an enemy inside a house, he'd switch to high gain to generate a louder sound. The difference between the plugs is simple: the EB1 is for people who are going to be around one-off noises and the EB15 are for those who are going to be exposed to prolonged noises. We got a chance to test out the plugs on the loud show floor and we gotta say, the difference between high- and low-gain modes is easily recognizable and we feel like these earplugs will make superb head-hole protectors. Plenty of complicated graphs and numbers in the gallery below.

  1. I was wondering if you ever considered changing the layout of your
    site? Its very well written; I love what youve got to say.
    But maybe you could a little more in the way of content so
    people could connect with it better. Youve got an
    awful lot of text for only having 1 or two pictures.

    Maybe you could space it out better?

  14. Today, I went to the beachfront with my kids.
    I found a sea shell and gave it to my 4 year old
    daughter and said "You can hear the ocean if you put this to your ear." She put the shell
    to her ear and screamed. There was a hermit crab inside and it
    pinched her ear. She never wants to go back!

    LoL I know this is entirely off topic but I had
    to tell someone!

  17. Hi. I noticed your site title, "Blogger: Technology Guru" does not really reflect the content of your
    internet site. When creating your site title, do you believe it's best to write it for Website positioning or for your visitors? This is one thing I've
    been struggling with because I want good rankings but
    at the same time I want the best quality for my site visitors.
