Dear Sony Ericsson,
Despite what you may think, my ear is neither able to grab nor does it have an opposable thumb which would make it easier for me to hold onto your poorly designed Bluetooth headset.
Further you should note that a human being’s ear canal actually changes shape when they speak so nothing round is going to stick in there for long unless you figure a way to “dig in” without causing discomfort, pain, or diarrhea.
Thought you should take these items into account when designing your next generation of shitty Bluetooth headsets.
All my love,
