This evening i noticed a significant channel imbalance had developed in my MH750s that i've basically been using 24/7 for the last six months. Figuring they'd passed into the great beyond where so many of my IEMs had gone to before i resigned to the idea that i'd have to bust out the back up pair i'd saved.
Before i did i gave them a once over and noticed the grills had some wax/dirt build up so set about scraping it off hoping that it was the cause but doubting it as the right bud had the most and was fine, the low volume bud being the cleaner left.
The grills didn't really clean so well, in fact they seemed to absorb the gunk as i tried to scrape it off and i decided to see how they sounded with the grills removed figuring i had nothing to lose and spare 4mm metal mesh i could replace them with....
Low and behold the imbalance went away, and the treble even opened up a bit with the new grills on... that veil in the upper mids and highs I've been referring to might have been ear wax...
