I don't get the rage....
If you don't like them, don't buy them..
I do not expect stellar sound from any $159 pair of BT headphones.. The price is actually fairly cheap all things considered and compared to other high end BT headsets.
As far as loosing them, plenty of places on eBay are selling straps for like $3 that will make them look more like traditional BT earbuds and might keep you from loosing one, or both..
Who expects Apple to replace one if lost? I'll give Apple credit for selling replacements individually. They could have just sold the set, so if you lose one you'd have to buy again as a set and at full price.
I don't know.. I don't have mine yet and the tracking # says they've ben delayed (???) so I can't comment completely on them yet.
