Hey all, i'm super new to, well, anything audio related. I picked up some Truthear Reds, but I'm trying to get a very specific sound out of them and Im kind of lost.

I like a really nice rumbly bass. I saw some posts and reviews that said these could do that, but I haven't been able to get that that sound. Currently i've used the stock silicon (Mediums), and some Render eartips that were recommended by Zeos. I have some Spinfit W1s and CP155s I will be trying when they arrive tonight as well as the foam eartips that came with the tips. I tried with the adapter and without. This is running off a Desktop PC running Windows 11. I've tried both having it directly plugged into the 3.5mm jack in the back of the motherboard (using an extension cable), directly into the front of the PC in a 3.5mm jack and using a DAC a buddy of mine gave me (E10K Olympus 2).

The issue i'm running into is that there's no rumble, there's no oomph on the songs I like (mostly heavy metal and electronic music.). I like the sound of distant thunder rolling in the hills, or heavy sound like the thud when you drop something heavy. I like music that feels like i'm squatting 400lbs, lol.

Samples: at about 5 minutes in, there's the solo downtuned guitar leading into the "Death Take Me Home" lyric,

Second Sample:
the opening bass is smooth and rumbly, to me it sounds like murky water looks, if that makes any sense. then of course the guitars come in and it's mindblowing.

The samples above are just slow and rumbly. I want the oomph back. None of the eartips above give me the thumping rumbling bass im looking for. Maybe Reds can't do that? My Airpod Pro 2s can when connected to my iphone with no EQ.

On my computer, if I use PEACE APO and use one of the bass boost settings (I think it is), I get that. I don't know what setting it is since im at work atm, but I'll try and edit this post once I get that info.

I really like the depth I get of these, im not trying to overpower the sound, I just want the rumble back.

Any help or advice would be greatly appreciated.

Hi @Kreiger! Welcome to ASR.

It sounds like you're just not getting a proper seal at the moment.

This is crucial if you want the full bass response of any IEM.

Try running the tone generator below and report at which frequency the bass starts to roll off, as well as when bass becomes fully inaudible:

Thanks for this! That would explain an issue.

For my Airpod Pros, im used to using the Comply foam tips, which make a fantastic seal. Thats part of the reason I picked up the t600s for the Truthears.

I figured the Renders would seal properly since they're also kind of foam, but no such luck. I had some KZ SZNs and those sounded good as well, so maybe I can try those ears, just to see if they seal well.

I'm at work atm and can't test obviously but i'll report back once I do test.

Hey, put in the foams that came with the Truthears and ran the test.

Using FIIO E10K. Bass off, Gain set to L.

WITH Adapter:
Starts to fall off about 30HZ, and at 20hz it's just a slightly unsettling rumble.

Without adapter, its about the same, but fainter, 21hz-22hz is where 20hz was with the adapter.

Using 3.5mm jack plugged into the back of the desktop
About the same, tbh

Here's the interesting part, I kicked on PEACE APO again to the setting that gives me the sound im looking for, and it took the HZ down to about 14-15HZ or so to duplicate what was at 20 before.

Here's a screenshot of the APO setting. I dont know what any of this does or means, like im not sure what a "low shelf filter" is.

I have my reds in now on the train home with iphone and dongle - I think it's my most enjoyable listening experience . Best audio purchase I've ever made - bar none!

Edit - and definitely get the comply tips ... so much more comfy

That's a LOT of bass, which further indicates that you're not getting a good seal. Try larger eartips or aftermarket ones. If KZ ZSN fits you, then maybe try using their eartips on the RED, or getting the KZs Star eartips. There are a ton of other brands to choose from: TRN, Tangzu, Moondrop, Spinfit etc.

I have found the reds to sound great but they are too large for my ears. To get a good seal actually hurts due to the diameter, even with the smallest tips.
The chu2 fit me much better, and 7Hz timeless fit better as well.

Chunky nozzles are fairly common to multi-driver IEMs. I was more sensitive in the beginning and adapted over time. You might adapt too if you start with short sessions and take breaks in between. You might also be unlucky and never be able to handle chunky nozzles.

Having started my IEM discovery journey, a little more than 2 years ago with the (blue) Truthear Zero, amazed at how great the experience was/is, I then purchased the Hola, great as well, aren’t all IEM great once you mastered the seal procedure, to then follow up with the Lindsoul zero2, very good as well, but harder for me to achieve seal, doable, but not ideal for my ears.
I just ordered the Red to complement my journey, sorry, could not resist, less than 50 cnd $, on sale at Amazon, so much sound for so little and I already know they fit me well since I already have the blue.

To all my audiophile friends out there, don’t miss out on the IEM experience, give it time to adapt, think of it as speaker placement, the reward is totally awesome, some recordings you thought were faulty might give you a big smile once they get trough your ears without distortion and with proper frequency response. All that for less than 50 cnd $, really? Yes really.

 

[mc.god]

LOL, I just connected my Red after a while they where lying unused and when I took off them the left tip just slide out the nozzle and left into my ear . I use the bigger narrow bore stock tips since they give me perfect seal and comfort and only now I notice how easy they slide out the nozzles, there's practically no grip, and given the already massive nozzles of the iem I can state that the insertion holes of those tips are exaggerated. I tried them on the small nozzles of the KZ EDC Pro and they can't even make contact, I think that they can be really only used with TE Zeros.
Or maybe they have dilatate due to too many days of too much hot here in Rome

So I picked up some Comply T600 foams, and those sound like what Im looking for. I use complys on my airpods, so I figured it would work.

I do wonder if im losing any sound or clarity when I use them, and i'd like to try some different ones, but I feel like I would lose the sub bass rumble if I did. Im concerned.

I have spinfits, both CP155s and W1s. I tried the CP155s but not the W1s.

Any advice?

No need for snarky comments about deafness. A more sensitive IEM is better with less powerful portable devices but sometimes less satisfactory with headphone amplifiers and similar, that's all. And this may be a surprise but there is far more to portable and home audio than an iPhone and an Apple dongle.

I find the Red is pretty loud outdoors with JA11 dongle at 50% volume on Android.
No idea what's the measured RMS volts but using Amir's sensitivity numbers for 74dB SPL gives me only 0.66 mV, which is far less than I expected.

I’ve grown to love iem’s. The clarity is unmatched. Perhaps the most surprising quality of iems I find is how easy it is to listen to heavy music. The clarity turns distortion into detail. I’ve never heard so many backup singers in my life, or so many different kick drums etc.

Why do you not use the silicon eartips that came with the RED?

The Spinfit eartips will not improve sound in my opinion only the seal/fit has influence to the sound. Since everybody mentioned the Spinfit the prices for this eartips have been massively increased (from 8 to 25€ for two pair of CP155). There are a lot of alternatives available at much lower prices (Kbear, TRN, Fiio, Moondrop, Dunu, Tangzu etc.).

I quickly gave up on the stock tips for the same reason. I'm enjoying my Reds with Sonicfoam tips at the moment, but foam tips aren't to everybody's liking.

It's not you! The same thing happed to me and I barely used the tips before they no longer would stay on the IEMs!

I'll keep them for now, but I already have a bunch of other tips to try (TRN T and some no brand of various forms and size including foams), not all will fit on the large nozzles of the Red.

You do lose a few dB on the treble and upper treble, but nothing major. My advice is to try different size of eartips rather than different types before going for more models. Also, try a proper insertion technique, like pulling your ear from the opposite arm and keeping your mouth open while inserting the iems, like this.

 

[mc.god]

I'll keep them for now, but I already have a bunch of other tips to try (TRN T and some no brand of various forms and size including foams), not all will fit on the large nozzles of the Red.

TRN T tips can be mounted, even though you have to force them a bit since they are officially compatible up yo 6.2 mm nozzles, large size seal me very well and they are shorter than stock tips, so the iem can go deeper and stay more shuffle (less nozzle hanging feel), resulting also more comfortable than stock (at least in the brief period). They can be a very good and cheap choice.

Kbear 07 tips that came with 7Hz Sonus can be mounted too, even more easily, but still didn't try using them, anyway another very cheap alternative with an ample selection of width for any ears.

Kbear 08 that also came with Sonus are a no go, they have smaller stem and there's no way to stretch them to fit the zero nozzle.
