If you've never used custom IEM's before, there's quite a bit of isolation from them... up to -26dB. With the a964 A series, you can order different diaphragm units with different isolation levels - and it's almost like wearing ear plugs, with WIRES attached
For example:
The -15db (M15) modules - Invalid Link Removed
or the -20db (M20) - [Invalid or Expired Link Removed]
Those are FAR cheaper than a separate set of plugs.. YMMV
Very True and thanks for pointing that out. But, attending a music camping festival or busy concert I would rather carry around $200 hearing protection instead of $900+. It is all expensive, but way cheaper than hearing loss. I actually easily have enough unused gear laying around to sell and pay for a good majority of this, I should get on that one of these days
