Unfortunately when it comes to canalphones there's a lot of luck involved. No matter which brand or where they are made - most entry level (including AT) are made in China and more expensive models have the same failure rates as cheaper ones regardless of where they are made. I've seen models with a 50% failure rate last 5 years and I've seen models with a <10% failure rate come back 5 times in a row. I've seen $30 models given to kids and keep on going after 2 wash cycles and I've seen $5000 models fail within a month. Don't cross off brands like SoundMAGIC or Fidue, they put quite a bit of care into the build of their products, it's one of the reasons I'm quick to recommend them.
