So, I am going to start this little story on my B3's with the disclaimer, don't do this unless you are willing to risk all with your B3's and you may not even like the result... but it was such a journey and has given interesting results so I thought I would share anyway
I received a second set of B3's and like my first they didn't have any bass in the left ear compared to the right which is odd as I often have seal issues with my right ear not my left. So after exhaustive burn-in and testing myself in circles I concluded it wasn’t just in my head. My last pair cost me a month and shipping to HK to get me in the same situation so I thought screw it, I will open them up and see if there is an obvious issue…
After extensive fiddling I concluded that one of the two left drivers wasn’t firing properly (or at all, it is hard to hear such small parts). Then the unthinkable happened and they stopped completely… so, after trying other things, I started playing with the contacts and the series by touching the rear of the drivers together to see if I could get a sound to come out… and it did…
So, out came the soldering kit and I have added a new bridging wire in (as I said, please don’t do this unless you want to risk all, I was close to throwing mine out) and the results are really interesting…
1. It is now a really sensitive iem…
2. The bass ‘seems better’
3. I originally thought I might have killed the soundstage but I have been doing comparisons this morning to my earmax er80 and I have been surprised to hear that it is still much more spacious and clear than the earmax
I would love to hear thoughts on what I may have done to it and PLEASE take my impressions with a bucket of salt as I am doing a lot of this from memory with the original (possibly faulty), not direct comparison. I am posting for interest and investigation sake… if you choose to play you do it all at your own risk J
