When your[1] answer to a dongle problem is "add more dongles", you really need to rethink the situation.
1. The generic "you", not specifically you, Phillip.
Sounds like another dongle to me! The last half of your sentence contradicts the first half.

Am I that weird?
Wouldn't the dongle just be permanently attached to your headphones ?
Or that my headphones are always used with just iPhones.
Basically, no more plug-and-play. This is exactly why 3.5mm was good: universal plug-and-play.
