Well, it seems like it was impacted ear wax from probably using q-tips. I used over counter ear wax remover and it did wonders to improve my hearing on the right ear. Thanks for all the feedbacks.
hearing imbalance
I got into hi fi last year and loving every minute of it and constantly upgrading my system. However, I noticed that most music I listen to lean slightly to the left. I thought it was room acoustics or the stereo recording (since strings in an orchestra are on the left). However, it seems my left ear has better hearing than my right ear especially with high frequency (just plugged one ear at a time and tested). This is very unnerving as I can't enjoy music fully, is this common for many people? How do you go around these problems?
