Shure SE Series Earbuds / Earphones
Electronics
I wouldnt go below the SE215. It's a steal at $99 and most people don't need more than that. The quality only gets better the higher you go but only real audiphiles would need the SE425, SE535 or the beast SE846 which has a true sub. You can replace the cables over time, you can buy a new cable that has a mic for phone calls.
Warranty
Limited
A valid purchase receipt from an authorized dealer is required for warranty service on all Shure earphones. In the U.S., warranty service will only be considered for products purchased within the last two years and covers manufacturing and material defects only. A non-warranty fee will apply to products determined to have failures relating to misuse, abuse, or earwax buildup. This fee will also apply to products less than two years old without a valid receipt or purchased from a non-authorized retailer.
