There is nothing special about Neodymium magnets, other than they can have a larger magnetic field for the same size of magnet (or the same magnetic field in a smaller size).
The downside is that Neodymium is more brittle.
To be honest, it is not important at all whether the magnet is Neodymium or not - the manufacturer would have designed the headphones to perform at their best with the magnetic material used.
Neodymium is just marketing hype - it's a good magnetic material, yes, but it's not a magic product.
Most manufacturers don't even say if it's Neodymium or not as it's so unimportant. Though probably a large number of headphones use Neodymium just because you can make the headphones smaller and lighter for the same power.
