Just make sure you get a good seal. With the S Symbio W I didn't get a seal and therefore zero bass. Symbios aren't as comfy as the Spiral Dot, foams or Fiio tips, but they're not bad. For more bass and comfort, you can mod them by removing the foam insert.
See, just goes to show, we're all different. I found that the Symbio's gave me the best seal, and therefore the best bass yet, far better than even the supplied bass tips.I agree that the Symbio W aren't as comfortable as foams, so i experimented with the N's, and they were definitely more comfortable.
On a side note, any tips on reducing hiss and what sounds like background static (very random and unpredictable) with my FiiO Q1ii / FH5 and 8 core copper 2.5mm balanced mmcx cable connected to Note 9. Someone said its possibly the balanced output of the Q1ii (and the fact its apparently not magnetically shielded?) picking it up, as I never had any background noise using my 1more's on the regular 3.5mm output.
Any help or advice would be welcome
