For the nit-picker and nerdy ones here, I’m giving the specs and technical sheets . For all the others, you can just go to the next page to see how the S8F performs.
Knowles Balanced Armature Drivers: “The more, the merrier” or so they say ?
The Fearless S8F carries 8 drivers. If that was exceptional a few years ago, you can find cheap IEMs nowadays with as many drivers as you like. The KZ AS16 we reviewed a while ago is another example.
That said, it’s still a lot of drivers and even if you pile up some transducers, that doesn’t mean you will end up with a flagship. You have to properly tune them, add the right filters and choose what kind of signature you want to develop.
Even though, Fearless sent us two multi-driver IEMs already, and all of them were very good. So yeah, unless they screwed up somewhere, we should get at least, sound performance as good as the S6 Rui. Maybe more refined ? I hope so.
The upper range of the spectrum is taken care of by Knowles drivers, where the lower range gets Sonion drivers. The Sonion are double-bodied, so one of them count as double drivers. The driver setup is as follows:
- 1x dual Ultra-High driver from Knowles
- 1x dual Medium-High drivers from Knowles
- 1x dual Medium-Low drivers from Sonion
- 1x dual Ultra-Low drivers from Sonion
Fearless goes for a 4-way crossover and 3 sound tubes on the S8F, and 4 tubes on the S8 Pro. As I don’t have the S8 Pro I can’t say if the difference induced is palpable, or not.
