In Which a Bunch of Intrepid Audio Guys Go Hunting For Something Cool Amongst the Bad Guitar Players

Meanwhile, Westone is addressing the “boy in a bubble” isolation that keeps many performers from embracing the act of sticking monitors in their ears. The SD1 system features computer-controlled compression, limiting and parametric EQ (you can save four processing presets to the beltpack and click through them) along with a pair of sub-mini mics attached to the cable that
feed an ambient signal into the mix. It was refreshing and kind of strange
to be able to have earpieces in and carry on a conversation. Rumor has
it that this technology may make it into some other products as well.
This is one to watch.
