Pic shows the channel matching on top, and the effects of covering the vents on the bottom.

Sound: I won't go into detail, it sounds fine, bassy and decent timbre. Honestly sounds like a Wan'er with more treble and a bit more bass, both changes that I like.

Channel matching: I've seen worse, I've seen better. It is far from good, and the discrepancy is big and wide enough to be slightly audible. I wouldn't be bothered after a while but it is a bit disappointing. The only real issue is everything below 1khz, the rest above is small enough to not be distracting.

Vents: The effects of covering the front and back vents are as expected, but the changes are decent. You can cover the front to have more bass, cover the back to decrease bass, or both to reduce the region around 100hz. Too much of a hassle for me, I would just use EQ.

Distortion: Nothing much to say, inaudible and stuff. Surprising amount of 3H but that's that. 104dB.
