Yes. We do systematic durability tests. We pull, drop, scratch, water etc during the testing and quality assurance phase just to ensure that they live up to the high quality standards. However there will be limitations to what they can withstand. The buds are also Sweat Proof and live up to a very high industry standard, so called IP64.
In terms of whether conditions: here are the heat specs. Conditions: 60 ±3°C with 50±15% RH (full performance). Duration: 1 h ramp, Functionality check after 2 hours at set temperature and new function test after 1 h at HH temp.
