IEMusic
Headphoneus Supremus
Hi,
I kind of want to conduct an experiment with Legacy 3 users because I found variance between my first set which had channel imbalance and my new set. I bought one with serial ID 317 that had channel mismatch. One had a huge dip after 3K as shown in orange line below. 13dB dip in that range. The other channel didnt but had elevated bass. Then I got a replacement sent that looks like the red line and sounds a lot better, in my opinion. The new serial is 413. When I looked at hawaiibadboy's review graph his looked like the orange graph pretty closely, while if I looked at Crinacle's, it looked closer to the red line -- like my new set.
I tested my L3 pair with those test tones, and the 4KHz tone sounds slightly louder than the 3KHz tones. The 4KHz and 4.5KHz tones sound equally loud to me. I don’t exactly know what this represents.
As an aside, when listening to a high frequency sweep, it subjectively extended well beyond 10KHz without much of an audible drop off for a while, but the the left side dropped off earlier than the right side. I don’t know if that’s due to differences between the two IEMs, or due to my hearing (I haven’t had formal testing in a while.). I really would love to be able to graph my IEMs.
