Just got this one because my old phone's headphone line-in was broken. I've had it for 5 years so I thought I could use a new one and since the only uses I have for a phone is making calls and listening to music it seemed like the right choice.
I used to listen to music with my phone as well, but buying an Ipod for that is really worth the money.
Phones and sunglasses do not last long around me.
I think sunglasses aren't meant to be last long.
