Hi doctors, I have not been getting morning erections for the last 3 years. This started after I had recurring urine bacterial infections. I visited a government hospital urologist, and they told me they will do a test and asked me to bring headphones. I am confused about this requirement. I do not have headphones or earphones currently and headphones are expensive for me. My questions are: Do I need to buy headphones only, since headphones are more expensive, or will normal earphones also work? Will wireless earphones/Bluetooth earbuds work for the test?
