Let the hive mind of Engadget get that for you.
"I'm looking for a pair of quality headphones that aren't seemingly made of glass. I'm an avid BMXer which causes me to frequently bash on any type of technology that joins me for my daily riding. I've been through the higher quality headsets in the Skullcandy line as these are supposed to be built for "abuse," which is laughable. I cant wear earbuds or canal buds, as my large ears seem to have a repelling property upon anything that sits in them. Wired or Bluetooth doesn't really matter, but I need something that can hold up to taking a few hits every now and again. I'm trying to keep 'em under $150. Thanks!"
Anyhow, switched to T-Mobile when I left Cingular. Been with them seven years now. Out of contract for five. I have not left because every single problem I have ever had has been promptly and courteously addressed. They aren't push-overs but they definitely strike the appropriate balance between being a business -- run for a profit -- and doing right by their customers.
As an additional extra, longtime subscribers were recently awarded unlimited voice plans for 50 bucks a month -- no contract extension required. This was ten bucks more than my already very excellent plan but for many more minutes. I now pay 75 monthly for unlimited voice and data, killed my other phone, and finally got (much needed) internet-to-go.
If you don't need an iPhone and get solid coverage in your area, I recommend T-Mobile wholeheartedly.
