I've worked in professional audio for almost a decade and have a HIGHLY trained ear. My hearing was excellent up until a few days ago, then suddenly... I noticed tinnitus in both ears one night. I was shocked, I've basically been in a quiet environment for the last 2 years thanks to the pandemic, and have no other health issues.
I have been using Airpods Pro for about 4 months, so decided to see if anyone else had perhaps had a similar experience and... Can't believe how many people have had the exact same experience. Correlation does not = causation, but it does mean this should be investigated more deeply. This could be huge. Tinnitus can be temporary, but just as often it can be permanent, i.e. you'll hear that high pitched ringing in your ears for the rest of your life. It's a deadly serious condition, and I am not being hyperbolic in the slightest.
As an audio professional, my ears are my livelihood. Knowing this, I am always-always-ALWAYS extremely careful with them.
FWIW, I've had issues with my right earbud not working in ANC or Transparency mode 90% of the time, so I usually do not use those features. I took them into the Apple Store once for repair, they swapped the right earbud for a new one, which surprisingly had the exact same problem as the first one. Thousands of posts on forums, as well as the Airpods Pro replacement program already setup by Apple, indicate that these faulty modes are common, and that the product is widely defective.
If you have had a similar experience, please share your story.
