Reply to comment by extremeelementz in Please help me understand why the Truthear X Crinacle Zero sound like they have more bass than the S12 Pro's I just purchased? by extremeelementz

Another possible consideration, did you volume match them and if so, by what method? If one is a bit louder, they look close enough in sound that the extra perceived bass from loudness increase could also explain it.

Well I volume matched them to the best I could with my own ears. I don't have a good device to determine if they are accurately at the same level.

I did try to increase the volume little by little on the S12 Pro until it appeared to be at the same volume and even went a little further thinking maybe they just need to be pushed more but that just increased the volume and didn't give me more bass.

That does make it seem a bit like a sealing issue if the bass stayed low with increase volume. If you ever want to do a pretty good volume match, a multimeter with AC voltage is a good option for cheap.

Do you have access to a PC to listen with that you can use EQ APO on? If so, you might put a low shelf on the one that has less bass. If it takes more than 1-2dB to sound like the other one then it is probably certainly a sealing issue.

An alternative test is to use a tone generator like this one and see how low it goes. If the seal is broken on the less bass one, it should roll off much sooner than the other.
