Not sure if joking but to serious users this is really important - you can just plug in your headphones and it works - you don't need to worry about which device the phones are connected to this time (I pair my bt headphones with many devices) or signal noise (I still have this problem when using wifi and bluetooth at once). There are even Android devices dedicated for audophiles like new Sony Walkman!
Not joking here WSJ has admitted, after a lot of pressure, to receive money from China Daily it's just not very well known.
