Glass recorded with Tascam DP-008EX internal mic

I recorded the same sound with three different recording devices. This is Tascam DP-008EX using internal mic.

I tapped on glass with a pen. I splashed a bit with the pen in the water that was in 2 of the glasses. I also tried to play the glasses. The result of that was somewhat mediocre. In the background, you can hear the hum from the fridge and freezer.

iPhone. Disadvantage. It has a kind of 'Auto level'. Maybe it can be turned off?
Tascam. Not as dynamic recording as with H1.
H1. Also picks up background noise clearly. Most sensitive.
