[Elecraft] Very Efficient Ear Buds

[Paul Christensen]

Earbuds that completely seal the ear canal scare me.  Has earbud transducer 
technology advanced to the point where the transducer's cut off from the 
source below a reasonable safety level (roughly 100 dBSPL)?

Over the years, I've had many mistaken disasters when plugging in closed-ear 
headphones into dangerously loud sources.  Sometimes my reflexes were 
fast -- other times not.  I cannot imagine the damage I would have caused 
with earbuds that fit perfectly into the ear canal.

As my teen-aged daughters go through the iPod craze, earbuds of any type 
have been off limits.  We only allow them to wear unsealed, on-the-ear 
headphones.
