I'll be trying out these 1More ComfoBuds Zzzzzzzzzs tonight. Here's what they look like next to my APP.

does it have that vacuum effect and change the sound when pressed against the pillow?

i have some small TWS in the past that are flush to my ears when sleeping, but the vacuum effect on them when pushed by the pillow sometimes not only changes the sound, but would choke/cut off the sound.. they're dynamic drivers though, maybe that's a factor. curious how this Comfo Z with BA would perform.

currently for my "going to sleep" TWS, i would use my open earbud ones, as they're more comfortable, and i don't really need full isolation/cancelling to sleep.

You could probably use foam tips to alleviate that.

The Acoustune AET08s fit but I get an annoying sound when I’m chewing food or running on a treadmill. otherwise they sound awesome
The included tips in medium didn't give me a 100% seal/fit, and I felt the buds moved in my ear. If I try the original L, I get the annoying sound you describe.

I was using the Final Type E TWS for a little while and those fit…size large, too.
I have the Final Type E large. Will try later.

Got the Geminis yesterday and haven't tested much yet. But when they're in place, they sound awesome! Best TWS I've heard. So open, clean with tight, quick bass.

Will try some tips today, but fear I might get in trouble finding something to give me a perfect fit. Maybe I have to try some foam with these.
Silicone make them either move in my ear (pushed out in a way), or make the annoying sound while moving the mouth, like Luke says.

Nice! If they impressed someone with Elysiums and EE Legends I’ll def grab a pair :)
Just to add on a bit. This was my last audition after listening to many IEMs for 2 days, so my ears weren't in top shape when I got to these, but I liked it for a tws. I did order it, so I'll report back to this thread once I receive them

The Geminis sound great, but my God... the driver flex with almost all tips are AWFUL! How can you guys rate these on top of your list?
They are ok with foam, but the foams I have, limit sound quality compared to silicone and also the Symbio by Mandarine. The Symbio sound really great, but the driver flex with those are just atrocious... I'm actually afraid the driver will rip apart :triportsad:

I've said it before, and I'll say it again... there's no such thing as a perfect product.
I wish my MW08S would sound like the Geminis, it would be close to perfect... but they really don't :frowning2:

I've noticed this too. However, I've noticed that driver flex can happen to any dynamic driver earphones. My Ibasso IT01 have it as well, and are still going strong after 1.5 years+. However, in case of the Gemini's I think the 'cascading decompression chambers' might have something to do with this as well. This begs the question; is it actually the driver, or perhaps this chamber thingy that we're hearing?

I guess this is very individual, and depending on the tip (size/material), but for most of the tips I've tested now... this is difficult to live with.

Tried to google "Devialet Gemini driver flex", and found some hits.
So I guess it's nothing wrong with my set, since several people hear it too.

From Stereonet: https://www.stereonet.com/reviews/devialet-gemini-true-wireless-earbuds-review
"Upon initial insertion, there's a cringe-inducing driver flex noise, a sort of scrunching paper sound. It doesn't appear to cause any issues with sound quality, but one can't help but wonder about driver longevity if this is an ongoing issue."

I don't have this with just insertion, but everytime I chew/move my mouth... I hope I find a foam tip that sounds good, or I will sell these quite quick...

with regular IEMs, yes, usually going with foams would make the driver flex problem better, but in those particular TWSs it's either the problem persist, or in some of them it got better but i can't fit them inside the case anymore, so i ended up letting them go

so for the mean time for sleeping purpose it's open bud TWS for me, or at leasr until i try some all BA driver TWS to see if it works

I just assumed it was the decompression chamber, too

Looks like the Soundcore Liberty 3 Pro is coming soon and it sounds like it's got pretty much every single piece of TWS tech possible in it: LDAC support, ANC + transparency modes, multipoint, wireless charging, wear detection, wings for better fit, some kind of built in pressure relief and app support. Think I'll be keeping my eyes on these, hopefully there's no hiss this time around...

They can take my money now! But I'm not sure why they needed to release the 2 Pros...
