What makes you like more about the Sonus, if I may ask? It's in my basket so your comment made me curious.

Exactly what you can see from that FR comparison: Sonus has a tad more sub-bass, where Zero can result a little light on some songs, Sonus rises earlier in the pinna gain but are a bit less energetic in the 2.5k-4.5k range, avoiding the hint of shoutyness that Zero can give in some songs, Sonus are more smooth and linear in the highs region (don't know if it is due to the BA drivers) avoiding the 12k peak of Zero that can sometimes result predominant.
It's a matter of fine details, as i said i love both iems, Sonus just a bit more, I find them extremely clear with many genres, and greatly enjoyable even at low volume, that is a big selling point for me.
And again, even though Zero fit perfectly my ears, Sonus fit even better with their little wing on the back of the shell.

Thank you so much for your reply! You mentioning low volume listening is exactly what I'm looking for as well. I worried that the highs might get too smooth in such a case. That's why I was considering the Letshuoer S12 as well.
 
Does anyone have a recommendation for an alternative cord that's more substantial and a few inches longer? One that doesn't tangle?
 
I have purchased 2 pairs.
1 with USB (my mistake) and one with 3.5mm jack.
I end up using the USB version more.
It also includes a microphone, it seems, but quality for conf calls is quite poor.

One of the side now outputs a much lower volume.
I swapped with the corresponding one from the other pair and all is good.

Excellent value for money (but could be more reliable, for sure)
 
 
Guys I have these but which tips are you using because I find the fit horrendous. Maybe I ruined my ear canals with foam earplugs over the years.

Cant advise on size obviously but the Azla xelastec work well. And the Moondrop Spring tips . YMMV of course but my advise is get the widest tips you can (as in the width of the dome)

I have large ear canal i tried the spinfit large was a disappointment. This one was better but still not perfect but the bass started to be good

 
Thanks for the suggestions guys, I don't think it's made my ear canals overly large, just made it so the IEMs tend to slip out a bit easily. I don't know, perhaps it's just this IEM in particular. I'm not used to wearing IEMs.

Dunu S&S eartips as well as Penon Liquor ear tips may be a solution to the iem slipping out, I use both/mixture of these on my iem’s and no matter the iem/nozzle shape I have always been able to get and maintain a good seal with those above

I recommend spending time with the included tips and find the one that provides the most comfort that just seals. As in, if you go one size smaller, you lose the seal. Measure the dimensions (mm) and order accordingly.

This worked for me. Knowing that the W1 fits a little bit deeper than the stock tips, it provided a perfect seal but with better comfort compared to the stock tip. And the silicone is really grippy and won't slip out.

I'm new to using EQ and all of this audio jargon but I've managed to find something that makes the Zero:2 sound satisfying for my ears. I understand now that everyone hears frequencies subtly differently and can have conscious and unconscious biases to prefer different tunings.

So while already a very 'technical' set I personally found the treble to be too high. Sounds such as claps or percussion were so clear but they just felt too loud in relation to the vocals and the rest of the instruments in most tracks.

Below is the EQ I'm using with a Qudelix 5k:
Code: 
CH: 0
TYPE: PEQ
Preamp: -1.3 dB
Xfeed: 1 0
Filter 1: ON PK Fc 2300 Hz Gain 1.2 dB Q 0.800
Filter 2: ON PK Fc 5300 Hz Gain -4.1 dB Q 1.100
Filter 3: ON PK Fc 5500 Hz Gain 1.3 dB Q 2.000
Filter 4: ON PK Fc 11000 Hz Gain 8.9 dB Q 2.000
Filter 5: ON PK Fc 12000 Hz Gain -5.5 dB Q 0.500

If anyone uses Rockbox, I've settled on simple treble and bass adjustments over EQ:
Code: 
Settings > Sound Settings > Treble > -5 dB
Settings > Sound Settings > Bass > 4 dB

However, I may get around to inputting the EQ above into rockbox. I've not done it yet because of the potential increased CPU usage and the hassle of using the scrollwheel to enter EQ.

Maybe this makes me a 'bass head' ?

I still can't quite believe how great the Zero:2 sounds. After doing more A/B testing with the 7Hz Aero they're just not in the same league as the Zero:2 and I think I'll use them only for audiobooks in bed as they're less fiddly without ear hooks. I don't think I'll be looking for any other IEM or tuning.

There is nothing wrong with being a bass head.

I'd suggest trying to make DIY tips from from earplugs.

Just cut the plugs a little bit shorter and punch a hole in them with hole punch pliers or make an appropriate hole some other way. I like the seal and the isolated sound with these DIY tips.
