So I just received a STAX SRM-1/MK2 energizer along with Lambda Pros, and while they're doing a great job reproducing sound (for the most part), I'm noticing strange hissing coming from both earspeakers.
The left side has a very slight hiss that sounds like air slowly coming out of a balloon, but this is perceptible only at quiet moments.  I thought the right side was fine until I turned up the volume and noticed that same "air-out-of-a-balloon" sound, except much much louder, to the point of being distracting.  I've tried discharging both sides, and sometimes the sound goes away for a little while but then seems to come back fairly soon.
I just got these today, and have been listening to them for just 10 minutes before posting.  However, I'd like to figure out if these are defective or if I should expect this.
I haven't noticed channel imbalance like many users complain about, but I haven't checked carefully for it either.
Thanks for the help!
