The doctor had a look at the ear canal and exclaimed "My gosh, you have the most ear wax build up I have ever seen!". I said to the doctor that you looked at my ears six months prior and said they looked OK!! A nurse spent 1/2 hour irrigating the ear canals and pulled our near perfect ear wax molds of the canals. After treatment and the water removed I immediately noticed better high frequency response and directional spacial cues. Wadding up a piece paper no longer sounded dull but crisp and crackly. The "cotton" in my ears was removed. I drove like a bat-outta-hell home from the doctor's office and turned on the sound system. Ahh! I have been missing a lot of sound quality and its like I have a new sound system! And no more distortion on pure tones!
So from now on with doctor visits a thorough examination of the ears is a priority requirement. Get those ears inspected and tuned up..
