Just wanted to chime in to say that I have a pair of Deltas - 1st. gen hybrid. I agree that Trinity has a quality product here. Having the ability to change filters is a bonus. Typically I use a gold filter (the colours are different for the various models) on mine for the "flattest" response, but if I want to kill off some grey matter with some metal, then I'll just switch to the gunmetal (more v-shaped) for s'more bass. I was going to get the PM4, but had to bail since I needed a new laptop. Hopefully in the future I can check out some of the other models

These look like a quality product as well and the idea of being able to tune them is very attractive. Especially iem's which might be quite variable in different sets of ears perhaps. I just tried some 1More multi driver iems and they are very good but I think that they retail at nearly twice the price of the Vyrus which is going at £59.
Some of the higher end models look good as well. I wonder whether I could persuade Bob to send some out for review? That would be nice. I must admit, they all look really interesting with this ability to tune the sound and if the higher end models also offer better clarity, then they are really likely to sound good for most people.
My reasoning here is that if they are higher resolution, that resolution probably doesn't get lost by the physical tuning of the barrels so you end up with good resolution as well as a timbre that might appeal.
I'm also curious about what they call 'push/pull out of phase' aspect of them. I'm presuming that this might produce extremely fast drivers which would indeed give lots of detail if it actually works.
That's really what I'm kind of curious about, but I'm not forking out £200 - £400 just to find out. If I heard some and felt that they offered a really improved iem sound, then I would consider them given that they can also be tuned. The higher end Phantoms look appealing but the price .......
I know that this is kind of odd, but I wouldn't mind a slightly higher impedance as well, so that the noise is slightly better suppressed. Say, 24 ohms.

From what I gather the push/pull thing is like the iem equivalent of a dipole speaker. Similar to what AT is doing with the ckr9/10. Supposedly has much lower distortion

Looking on the site, I see that the filters just cut the top end while the shape of the barrel seems to alter the sound profile. Seems there are three choices and then the same three choices with treble cut. (Or filter) What's happened to Gunmetal with filter? I think that's about it ......... Might be an idea to listen to a man's spoken voice in order to test bass levels, Mark. Where music can sound 'enhanced' if the bass is raised, it does also depend where it's 'enhanced'. I find spoken voice to be a great highlighter for this. For sibilance as well plus womens' spoken voice helps the higher part. Once they both sound ok, then I listen for depth of bass as well as treble extension via music. Mark, stop it...... I might have to actually pay for a pair of these!!! Slightly chopped your post but there is only one gunmetal filter supplied and that is fitted with a damper. Initially I thought I was missing the other one but reading the filter descriptions and a few posts on HF it seems there is no gunmetal without the damper. Not sure why that's the case. To my eyes I'm struggling to see any clear difference in physical shape or dimensions between the various filters which makes me wonder if it is the metal they're made from or the fine mesh that is fitted to the top of the nozzle that influences things. The filters that have dampers also have this mesh at the top and also a white damper (a disc or plug that looks a bit like paper) on the bottom end. Thanks for the tip re. spoken voices. I'll have a listen to some to see which filters give best results. Oh, and I'm not starting anything. No way would I tell you to buy these or that you might enjoy playing with the various filters. But of course if you do mind and use that discount code But of course if you could talk Bob into sending out some of their IEMs on loan in return for an honest review that would be good. I'd love to hear your impressions and you have a good ear for these things. Just a pity Frans' dummy head isn't geared up for IEMs as it would have been good to be able to visually compare the FR curves for the various filters and see how they change things.

I guess it sounds a bit smoother?
I see how the filters work. They're not just blocking devices, but it's to do with the shape of the barrel and porting. By having a smaller port, the top end seems more apparent and by having a larger port, you get a bigger bass.
The wonders of YouTube.
I'm quite interested in the higher end ones, but it's just too much of a risk on a product that costs so much. Buying blind is a dangerous game and reviews aren't always as helpful as they try to be!!

Ah, glad you got a definitive answer. I did notice that Bob had posted some videos on youtube but hadn't seen one on filters so will need to have a watch.
Buying the Vyrus didn't feel like much of a risk but not knowing a lot about Trinity or their products beforehand I'm not sure I'd have been too keen to have bought one of their more expensive IEMs blind myself. I suppose a bit like you with the HE-350 the Vyrus let me test the waters so to speak.

Found it. Quite interesting how such small adjustments to the filters can change the sound so much (or our perception of it).
The ports look quite obvious in the pics but when I look round the gold filter just now a few times I initially thought there wasn't one. Then from the inside I noticed this tiny pinpri*k hole and sure enough the bleeder was there all the time! Still haven't found a port on the purple filters but they are the most bass light so perhaps they are not ported.

That would make sense. A nice big port will give a bigger bass. No port would knock it on the head!!
In the 70s, I had some small Mission speakers that were rubbish with bass until you fired the back port onto a wall. A corner boosted it even more but not always vet nicely. Block the ports, and they had very little bass.

Come to think about it I had some speakers many years ago that were the same. Also had some foam pieces that you could stuff into the ports to tone things down. A sock worked too. A special audiophile one that had been cryogenically treated.
Edit: having to use the wife's glasses as a magnifier to help spot the ports. Comparing gold to silver I think the port hole on the silver is closer to the top so position may also be important in terms of tuning them.

Some ports in speakers used to make a 'chuffing' noise with big bass notes as well!!
I am interested in these mainly because of the ability to tune them. Especially the high end ones. I'll email Bob .......

Am trying to picture IEMs with socks hanging out of the ports for bass tuning :-)

These are the prototypes I'm working on. 5 different pairs of varying thickness / materials will be included for tuning purposes. Happy to burn them in for a small fee

One on the way ............. The Sennheiser ie8 that I have also has a porting system built in but the problem with it is that the Senn never really develops enough top end energy and so always sounds a bit fat; even if the port is closed down. This one looks more tunable. I'd prefer a higher end one though TBH. It's too much of a risk at those prices though.

You sly devil you Did I mention they are rubbish??? I'm sure you will enjoy them Ian. This filter swapping is quite addictive and perhaps you can help me decide on the best one! In terms of value I don't think you'll have any qualms (you did use the HF code?). And they don't sound half bad once you find something that works for you. Edit: should add, that's not me in the pic above! That's my able assistant Jimbo. He's the brains of the outfit.

Well, your ears seem to align with mine Mark, so I'm guessing that they're OK. It's the tuning aspect that interested me. That's why I originally bought a Senn ie8 and put custom fits on them. TBH, I'm more interested in the Hunter, but there's no way I would buy one blind, or on the reviews by HF type people. That is the problem with iem's. No way to actually hear them before buying, so expensive buys are a total shot in the dark. It seems that they might be good value and I'll compare them with my 1More iem's. They're pretty good as well but there is no tuning facility. With so many choices, I can see that just that in itself could cause problems. The spoken voice is the key Mark. If that sounds good then they are probably fine. Iem's are quite individual, I think because of the way that they work and the shape of our ear canals. I just listen out for boom in men's' voices and sibilance on ssss and ttttt. Then turn up and listen for harshness or 'electronic' kind of reproduction. Then very low to see if anything stands out. Then I try them with music for extremes and imaging. I often find that speech is a much better indicator of what a headphone does than many other things. Probably because we're much more tuned in to those frequencies than the extremes. I also have some 'spinfits' on the way.
