iPad Air 2 sound vibration

Ok, so I'm a big time apple lover. I got rid of iPad Air 1 for the 128g iPad Air 2 (Gold). It's definitely thinner and much faster than the original. However, It has a terrible sound vibration when the audio is playing from music, apps, or movies, etc. I took the iPad to apple and they said it was normal. This is a terrible design flaw that apple doesn't seem to talking much about. I returned the iPad Air 2 and unfortunately re-bought the Air 1. I highly recommend buying the iPad Air 1 over the Air 2. Before buying the Air 2, I highly recommend going to the apple store and testing the volume to determine if the sound vibration is acceptable. Very disappointed in Apple for releasing a product with this type of flaw. I hope they correct this for the release of the Air 3.
