Wow, the plot thickens. I was beginning to accept that my tinnitus was pure coincidence, but now I am seeing multiple reports of a defect that may have caused my symptoms: apparently, one of the earbuds can spontaneously play back high-pitched or other erractic noises that could be harmful to the ear.
This user actually experienced tinnitus from the noise.
My guess is that this defect could have manifested while I was asleep, and it rewired or damaged my hearing in some way. It's remarkable how a "wellness" product wasn't properly tested and, ironically, could harm the health of a user.
I suffer from moderate tinnitus, a steady ringing sound. I bought these to help with my wife's snoring. For the snoring, good. But it does seem that after three nights use of Shower or Downstream at moderate volume my tinnitus is more pronounced. In looking around the web I've found people arguing that for tinnitus sufferers any constant sound via ear buds throughout the night is a bad idea. Frankly, I'm worried, and I'm angry with Bose for not adding a cautionary note to their product promotion.
