Testing IPX7 Ratings on Ear Buds

[RandallS]

I have a couple of pairs of Anker Sound Buds, as I like to listen to audio books when riding alone.
One of my sets are from Anker and are pretty good for battery life and audio quality.

I have just finished a personal test of their IPX7 Waterproof ratings.

I did not follow absolute testing protocols of 30 minutes submerged at 1 meter but used the following test methods:

• Leave product in winter vest chest pocket
• Use a Samsung test tank - set on on warm water with extra rinse and long spin
• Add an additional testing liquid - Gain
• Use test tank, on normal agitation to check how rugged ear buds are
• Once test tank procedure completed, run heat and secondary physical abuse test for 52 minutes

I am currently listening to a new best seller and am happy to report that the buds passed in flying colors, and they have a secondary improvement that they are nice and clean too.

I hope to not repeat this test with any other similar devices and don't recommend it for you either.
