Has anyone tried the lightweight in-ear headsets? Lightspeed and some others are marketing them, and are advertising 29dB noise reduction, which is better than the ANR headsets being sold. They use foam earplugs, which do have high NRR ratings, and don't require the clamping, sweat-inducing force of the typical headsets, freeing the pilot to wear whatever sunglasses he likes, and not requiring removal of the
button on top of the cap. I like the concept, but I'm reluctant to spend the money without knowing more about the possible drawbacks. Any experiences would be welcome.
