Query: I can't hear you

I couldn't use the default plugs, but the other ones work well. The micro-accoustics are not too bad if you use the foam adapters. The sound on these is incredible, and LOUD. I travel a lot and use these as a lightweight replacement for my Bose Quite Comfort 2 headphones. These are great, but make sure you set them properly or you will suffer from a lot of outside noise.
