I had a go at A-B-C testing the stock cable, the MDxMee cable and the Florea cable this evening but my test notes are a vomitous mess. The main differentiatior for me between the three was that the Treble on the Florea is less painful over a long listening period, and the slight bump in mid-bass over the MDxMee cable also made it slightly more practical in everyday settings.
Comparing the Mee cable to the stock one I perceive that the lateral soundstage is larger on the balanced cable, the upper mids are slightly less detailed while the mids and lower mids are more detailed and while the bass goes just as deep it’s less present in tracks where I expect it to be present. I also experienced loose connections on both the left and right earpiece with the Mee connector, which was frustrating.
I’m quite sensitive to treble which can kill some audio gear pretty quickly for me, I think I’ve established that I like a darker sound overall, so your experience may vary based on your hearing and listening preferences. Personally I’m considering getting the Planamic when it drops again and the Mee cable might suit me better when connected to that,
For the formal test I was playing a FLAC of the track ‘So Close’ by a local band called Rhombus (I think it’s on Spotify) through USB Audio Player Pro on an LG V20, but my long-term listening has been a mix of FLACs in UAPP and the highest quality Spotify has to offer. Here’s a playlist of stuff I was listening to longer-term to make those comparisons:
