It says the dimensions are 8x8x8. Can it really be true that they are 8" deep front to back? Aren't they 8x6x4?

They are not 8" deep Front to back. More like 4 is correct. But I have a huge head and they fit well on my head.

Will these cancel any music from really noisy neighbors? like neighbors having a party.

These will attenuate noise up to 110db. The level of attenuation varies across the frequency spectrum. These are not noise cancelling head phones. I wear these standing next to a noisy 10hp chipper/shredder which I can still hear the engine whilst running. In your situation depending on distance from the source of music/volume level/physical barriers between you and the source/your own hearing capacity will all determine if these earmuffs will attenuate the noise to an acceptable level for you. I have seen our Australian Military using this model whilst operating artillery guns so rest assured that these earmuffs do block out a lot of noise! Perhaps an anonymous phone call to the relevant law & order folk asking to pay a visit to your inconsiderate neighbours may just persuade them to use headphones instead. Good luck

I have a larger head 7 3/4 with head shaved. 7 7/8 with hair. Will these fit?

They fit most. You also may wish to consider a behind the head model, H10B. Thank you for considering 3M products.

These are listed as Active Noise Reduction, how is that possible without batteries?

These seem to be mislabeled on Amazon. They are not active noise reduction, these would be passive noise reduction. Thank you for considering 3M products.
