Eartips Trick for BQEYZ Spring 1
Well, I've tried to figure out what happened with Spring 1 boomy, bloated mid bass that I heard with my usual preference eartips like JVC spiral dot, Final Audio E, or any other fave tips.
Few users also reported that experience boomy bass on Spring 1. So I spent my night with eartips rolling through my eartips collection. I found the stock reference one is good but I can't get good fit.
Then I realized that there is something with the NOZZLE. the nozzle on Spring 1 is long, longer than average IEM, thus in sense will act as longer resonance tube and with additional eartips it even longer.
This will made bass part especially resonance much more, made the bass bloated or boomy.
No wonder few users experienced very boomy bass part, depends on eartips used on the Spring 1. Reference tips is good since it sit well without any extra lips (dont make more resonance tube), but in my case i cant get decent seal.
This is FR graph by out friend @Wiljen, all credits going to him :
As seen there Bass part are bloated because of that extra resonance.
So i was thinking how to get rid that, and short experimental was coming great. All you have to do is just PUSH the EARTIPS all the way down, past the nozzle attachment to shell a bit, so it will leave no extra lips on the nozzle. The edge of the eartips should be on same level with nozzle end, dont overlap at all. This way, we can still got decent seal, with your favourite eartips.
Please be noted :
1. Use wide bore eartips, because small bore will made bass still a little bit bloated, spiral dot will be fine but the dot effect is useless (anyway theyare already smooth on treble), or use Auvio,
or any wide bore tips
2. You just need to get decent seal, so dont worry about characteristic of the eartips, it wont affect the sound as there will be no resonance on eartips, even foam also will do good.
Here the picture for reference, spiral dot on pics :
Alternatively, you can cut foam eartips (cheapo one will do) and put in on same level on edge (dont overlap the nozzle edge)
1. Cut the foam a little bit
2. cut on the edge of inner eartips tube (the plastic) so we can make a way to push down
3. It will be looked like this, dont overlap it remember, make flat surface, same level between eartips and nozzle end. (it more confortable than the look trust me)
*edit : spiral dot have more air and perceive bigger soundstage than foam.
After that try to listen to your Spring 1 again, sound signature will be much more balanced, no more bloated bass, texture of the bass will be heard more, sub bass will be more audible (even though there is still some mid bass bleed, just a little) and because of not bloated, decay is faster, sounds tighter. This way mids also very clear, and highs are directly to your ear made them more lively. Normally this kind placement will made bass very light on other iems.
For me roughly now they will be sound like this :
Remember it is an edited version of FR from BQEYZ, but i roughly hear the bass level like this, just want to show you the bass level after this simple mods.
After this simple mod, suddenly Spring is coming. Enjoy everyone, please report and give a feedback about this. Cheers!
I didn't try your method but just from tip rolling yes there is noticeable difference in bass response. I tried on the left wide bore Tenmark Whirlwind Turbo and on the right Symbio w peel. With Tenmark bass is more controlled and with Symbio is a bit more noticeable but I get better seal with Symbio and I don't mind healthy amount of bass in my music.
With Spring 1 bass is not the problem. The way I see it, it's recessed highs makes the bass sound boomy and all over the place. I just had to add few dB in treble region to make it sound more balanced.
Granted this setting introduce some and just a bit harshness to some songs (rare songs I tried so far) but IMO much more enjoyable sound signature. I'll tweak it further later down the road.
