A balanced 4.4mm cable for my Sony DAP arrived today from AliExpress. Great looks and ergonomics for $35. Was about to get a 2.5 to 4.4mm adapter so I can use the FiiO balanced cable but the aesthetics of this cable was too hard to ignore lol. Finally found some time to do some tip-rolling too.
Stock with red stem: Very comfortable and great seal. The "bass heavy" variant of the tips were definitely too bassy for me, enough to be a distraction from enjoying my music. These were in and out of my ears after just a few songs.
Stock black: Again, excellent comfort and seal, although I was a bit OCD-ish about the easily visible dust specks on the tips. The "balanced" tips reduced the bass bloat a bit, and the signature is cleaned up somewhat. Good separation and clarity, however the bass thump was still a bit too much for my liking.
Spinfits CP100: The best comfort and deepest insertion, I could easily wear these for hours. Sound-wise, the bass is tightened further, with ensuing increase in apparent details. The imaging is more precise although the stage width is similar to the two stock tips. I could better hear height and depth compared to stock. Very good pairing.
Mandarines Symbio W: The best seal and isolation, a bit more shallow fit, but the foam pressure exerted would make my ears slightly warm after an hour or so. I don't know what magic these tips possess, but they provide the best resolution amongst all the tips. A lot of details are readily heard. The bass is the tightest and best-defined, vocals are clear and the highs are smooth while providing just a bit of sparkle. Also, the tips give the most out-of-head experience of all, with added spaciousness. They sounded the best for me.
