1. You've edited the thing, didn't you? Anyway, look at user #103. Capital P and capital B, remember?

Again, look at user #103. Slashes, remember? DD/MM/YYYY, not DD MM YYYY.

Now look at user #104. DD/MM/YYYY, not MM/YYYY.

2. Yeah, to standardise the whole thing. If you don't like it, then change all from #1 right til the last. By this way, you're making it easy for the V5 threadstarter (like how you benefited from mine).

3. Simple: DON'T FILL IN THE DATA THEN!

try to looked at the pard that where the sound came out, its seal by some kind of fabric...and the outside rubber plastic has seal the ear-hole..

if there's a space tat air can get into the ears then must be able to hear the sound from outside [after wearing the earphone] because sound is transfer through air [wave] so sound cant be transfer/projected in vacuum...

my expericent when wearing the earphone b4 playing any music, it feel like when swinming, when the ears  is in the water is cover the ear-hole..
or when the ear-hole is block by water after shawer, the effect is similar..
