Auglamour RT-1: The Imperfect Gem.
-written by Niyologist

Pros - Balanced sound, extended treble, Large Soundstage, Excellent Packaging, Removable Cable, Excellent shell design.

Cons - Springy cable, No chin slider, slightly recessed midrange (at least slightly recessed vocals), cable noise, Mild Driver Flex, finicky fit and seal (depends on the eartips being used).

Auglamour RT-1: The Imperfect Gem.


I’m a man that’s pursuing the Ultimate Sound. In a form that’s portable. A journey that’s paved by endless hard work and great commitment. The pursuit of Ultimate Sound isn’t just experiencing it. It’s also understanding it. So I thought it’s good to start at the basics. The foundation of Ultimate Sound usually begins from Consumer sound signatures. Basically V-Shaped sound (elevated Bass, recessed mid-range and elevated treble).

What led me to the RT-1?

Just curiosity. To see what type of Ultimate Sound the RT-1 possesses under $100.

Let’s start with what the RT-1 has.


The RT-1 has very premium packaging for Under $100. The box shell was made out of a thick plastic. It has a carrying case, A removable cable, 4 pairs of silicone eartips, and yellow foam tips. There’s also a cleaning brush to keep the top canals of the RT-1 clean. Along with a metal Auglamour charm and a metal eartip holder. I don’t know if it’s a charm. It seems like one. That eartip holder seems very convenient, but a bit sharp. So do not hold it out in public. It seems almost “knife-like”.

Product Type: dynamic driver and balanced armature hybrid in-ear earphone
Product Material: MIM Zinc Alloy & ABS & PC
Driver: ¢ 10MM dynamic driver & customized balanced armature driver
Divider impedance: 60ohm
Frequency response range: 20HZ-20KHZ
Input impedance: 32ohm
Passive noise reduction: -35 ~ 40DB
Sensitivity: 105DB ± 3DB
Cable length: 1.2M
Plug: 3.5MM Gold-Plated
Wire: PVC + oxygen-free copper

On paper. The RT-1 seems to be a bit power hungry. Yet it really isn't true. I only needed moderate gain and moderate volume.


Before I go on. I should mention that the cable used in these pics are an upgrade cable that I had sitting around. The RT-1 is pretty sturdy. It’s made out of a hard ABS plastic and molded very well for under $100. The shell has a triangular There’s a shiny multi colored reflective plastic that makes it dazzle with the surrounding lighting. It reminds me of the stainless glass church windows that I see downtown.

The cable is thick and sturdy. Yet I feel that a better job could have been done for the cable. It’s too springy and it doesn’t even have a chin slider. So that makes it difficult to walk around with. Thankfully the cables are replaceable. So I used a 0.75mm 2 pin Upgrade Cable. It fits very well. I didn’t even force it. Fits like a glove.

Isolation and Fit:

I find this part a bit conflicting. The isolation is great. Despite the shallow fit. The seal can be good, but for my ears. I would need elongated silicone eartips. Foam tips can work. It will need to be the perfect size. It might be due to the nozzle angle. Which is making the fit a bit annoying. I used the eartips I got from the Hidizs EP3 and was near a perfect fit. Still not ideal but it’s getting there. I’ll get proper aftermarket eartips soon. Otherwise, Comply Foam tips are perfect for the RT-1. It eliminates the fit and minor driver flex problem.

Now finally the sound.

Celldweller – Pulse Injector

Fall With Glory – Fight With Honor

Galneryus - Stardust

After long listening, I found the RT-1 to warm and smooth. With a sense of relaxation. The whole presentation is very relaxed. It reminds me of my Final Audio Design F7200. Although I feel that only the ambience of the entire spectrum is comparable.


This part of the frequency spectrum is handled pretty well. It’s very balanced and carries a bit of warmth. The bass from the RT-1 can reach to subterranean levels and it’s quite audible down to 30 Hz. The slam has moderate impact. The quantity is also moderate. Making this ideal for Most Electronic music. The texture of the bass is pretty smooth and almost elastic. Which can make the tone transitions easy to achieve. The mid bass seems to be even with the RT-1. Maybe slightly elevated in bass heavy tracks.


The next part of the spectrum for the RT-1 takes a slight back seat to the bass and treble. I would consider the lower mid-range the most recessed part of the frequency. It’s known because of the male vocals. I find the male vocals very relaxed and dulled. Just average in presentation. In fast tracks, the male vocals can get a bit lost in the mix. Pretty surprising because of the Soundstage size. Now moving on to the upper mids. The presence of this part is not in your face or behind the scenes. It’s generally inbetween. The female vocals do better. Unfortunately it’s not significantly better. The best aspect of the mid-range is the instruments. Mainly the percussion section. Now as for the strings. It seems to be smooth in general. That all changes when there's more energy into the strings. It starts to sound a bit coarse. That's not my cup of tea, but that may be good for others. I'm just basing this solely on personal preference. The drums perform well on non-metal tracks. The way the drummer taps on the drum gives a sense of nuance. As for treble heavy tracks, like Metal. It’s too splashy and bright. I usually end up equalizing it for a softer impact. Generally the mids are smooth and balanced. Unless if electric guitars are involved.


This part is bit tricky. The lower treble is elevated. Although, not tremendously so. It’s just slightly elevated for non-Metal tracks. This part of the frequency seems slightly energetic, yet tamed. It might get a bit out of hand. Depending on the mastery of the track and the genre of the track. Although it's not hot or piercing with most of the tracks I tested them out with. The details seem to be above average for the lower treble. As for the upper treble. It takes a slight tumble in both detail and decibels.


This part is interesting. The dynamics and accuracy played a huge part in determining the size of the soundstage. I used Stardust by Galneryus to determine the size of the soundstage. It's above average for under $100. It can keep up with the Havi B3 Pro I overall. Yet still falls short in dynamics and size. In terms of accuracy. It's decent. The instruments can stay clear and distinct in moderate and fast tracks. Although once again. It depends on the mastery of the track. Well mastered tracks will fare well with the RT-1.


This IEM is very unique. The sound it has is a bit complex and looks gorgeous. I feel that it's a great competitor for under $100 and can perform very well with most soundtracks. The sound it has is unique and it's not entirely bad. It's not your typical consumer sound. So this may make a good IEM for startup Audiophiles. If you are into a relaxed sound with a bit of top end shimmer. Then these IEMs are for you. Bassheads definitely won't like the RT-1. It's more treble heavy than the usual basshead IEM. If you can't stand driver flex. Then this isn't for you either.

Shozy Star II brief review
-by Mimouille

Disclaimer: I got a review price for the Shozy Star II + Takt Pro bundle, in exchange for a fair review.

Shozy and sister company Cozoy have been putting out quite some interesting products. I like quite a few things about this company. Their no-BS approach to this business, the well thought out and beautiful designs of their products (Rei, Takt, Star II), and also their straightforward communication with the community (yeah Charles, I am talking about you).

I first tried the Shozy Alien+ player, which was very impressive sound-wise but a bit short on battery, the Shozy Zero which was great for the price, and the Cozoy Hera which is a nicely priced well performing dynamic drivers with great ergonomics (I keep it as my office no hassle iem).

I was curious about the Shozy Star I, seeing them venturing into higher end iems (I completely missed the Star for some reason), so I approached them to get a pair, and was very pleased to be offered the Cozoy Takt Pro to review as well.

Here is the product description:
To summarize, it is a universal IEM selling for 419$ on Pennon Audio, with a standard MMCX connector and an undisclosed number of (BA?) drivers.

I tested the Shozy Star with most of my sources including Lotoo Paw Gold, WM1Z, and Mojo, using JVC Spiral Dots (the only ones I have that fit such large bores). I test with my music in Redbook and highres FLAC. I only compared with my S-EM9 side by side, made less sense to me to compare with my SE5 Ultimate.

I settled for the WM1Z as my best source for the Star II, Mojo was a bit boring, and LPG was too harsh.

Ergonomics and build:
There is not much to say, because everything here is close to perfection. The seamless integration of a carbon faceplate in a beautiful translucent black body provide an elegant and understated design that I really like, fit is easy and comfortable for all-day listening sessions. Great job.

An important disclaimer I want to give, is that for the past few years I have been listening to almost only 1-2k$ IEMs, so they are my reference. This tends to make me a bit hard to please when it comes to new IEMs, especially ones that cost a third or a fourth of my reference IEMs.

Shozy was apparently aiming for neutral tuning that is easy to drive. The result is a neutral slightly brightish IEM that is indeed to drive. However, its neutral tone makes it sensitive to pairing, so I recommend playing with sources to find the right match. The spaciousness and smoothness of the WM1Z work well for me.

The sound is indeed well balanced between frequencies, you feel like you have a fairly transparent window to your music. Bass is textured and well controlled, with close to no boost to my ears (didn’t measure and wouldn’t know how to read it anyways…). Mids are quite even and transparent without appearing too thing. The fact the image is very centered can make the vocals a bit caught between other frequencies, lacking air. 

Treble is quite detailed but may be fatiguing to some, with some sources. There seems to be a slight bump between upper mids and lower treble that creates this. The stage is reasonably wide and deep, but with a strong center-image focus. My only issues in general are first on separation, it is good, but the stage can get crowded on most complex passages, and second on general dynamics, when comparing to (a much higher end iem like) S-EM9, the notes are less well defined, the sound is less engaging due to less dynamic sound. But once again bear in mind we are talking about a 1.5k 9 driver iem…

Beautiful and well built
Comfortable and small
Neutral yet engaging sound
Good performance for the price
Easy to drive

Not as source eclectic as one might think
Slight harshness with selected sources or tracks
Separation on complex passages could better
Not the most contrasty / dynamic sound

==> Overall a very good iem in this price range, perfect for these looking for a neutralish tone but with a signature that remains engaging, all in a beautiful and comfortable form.

Schiit Audio Jotunheim Review
- A. `Reddog` Jones

"A sweet sounding mid level balanced amp"

I have been into this amazing hobby for about 4 years now. I have bought all of my own equipment and my reviews and impressions are my honest opinion. I am a amp collector, and feel a person can not have enough amps, especially good mid level headphone amps.

I have been watching a lot of Netflix and wanted to use my headphones, without using my TOTL amps. I am a fan of Schiit Audio and own a lot of hot Schiit. And when I heard about Schiit Audio’s balanced Jotunheim, I snagged one in a New York minute. I chose to get my Jotunheim in black. I chose only to get the amp only.

I really like the heavy metal/. Industrial design of the Jotunheim. This amp is nice and heavy and will stay on the desk and not readily slide about. This plucky black amp even seems impervious to the antics of my fat cat Kali.

On the back side of this amp, is the Power button, single end RCA/ unbalanced inputs and XLR balanced inputs as well as RCA pre outs.
On the front there are two switches and a volume knob. One switch allows for the selection between the phono, dac and amp functions. The other switch is for Low or high gain.

The Jotunheim balanced amps sounds very, very nice indeed.

If this amp had been out, when I started this wonderful hobby, I would not had gotten the Schiit Audio Asgard 2, Lyr 2 or my Cavalli Audio Liquid Carbon. This sweet little amp has almost every connection that a fellow audiophile could need.
It has SE and balanced inputs and SE and XLR headphone out jacks. And more importantly the Jotunheim has plenty of power to drive any headphone. Furthermore the Single end audio architecture is the best found in any Schiit Audio Amp. The previous Sumpter circuit was alright but the new design just sounds much better to my humble ears.

And to my humble ears the Jotunheim sounds quite good. The bass is nice and impactful, The mids are sweet with just a touch of edginess. The treble is good and was not sibilant. The sound stage is nice and the imaging is fairly detailed. Furthermore this amps has plenty of power and could drive all of my headphones.

I really like how my Audeze iSine 20 and Mr Speakers Aeon Closed back sounds out of this amp.

I am very impressed with Schiit Audio’s Jotunheim. This black beast of a amp sounds great and can drive any IEM or headphone one should have, This solid stage amp is versatile and has plenty of inputs and outputs. I think the Jotunheim is a great sounding mid level amp, especially for the money.

I used the following equipment for this review.
DAP: Questyle QP1R
DAC: Schiit Audio Yggdrasil and Gungnir

Overall Thoughts

Pros - Small, balanced, can come in black, heavy metal industrial design, 1/4 th and XLR headphone out. The SE architecture is Schiit audio’s best design to date.

Cons - The little mark on the volume knob can be hard to see in a semi dark room, especially after a shot of chartreuse.

Astral Acoustics Taurus IEM and Adapters cable review

Find them on Facebook:


Astral Acoustics Taurus IEM cable and two adapters. 
2.5mm balanced to 3.5mm SE and 2.5mm balanced to 4.4mm balanced.

Product Details

Entry model: Taurus IEM Cable
8 Conductors: OCC Copper with Litz

Taurus features a large soundstage and dark backgrounds. Vocals with just the right amount of warmth and thickness, and a surprising treble extension which, you'd never thought it could be experienced from a COPPER cable at this price.

Consisting of 8 Litzed 28awg OCC copper wires and Eidolic connectors, Taurus is nowhere near what can be considered as a bulky or heavy cable. Under light, this cable glistens, making it proper eye candy WHILE still sounding just as good as it looks.

Taurus will change your view on the stereotype that copper cables have dull highs and the lack of details. Sounding thick without sacrificing layering and details on the highs is what a proper copper cable should be able to achieve.

Price: $1800 HKD

Length - 1.2m approx.
Connectors - Eidolic
Solder - Audio Note

Taurus cable with MMCX connectors and a 2.5mm balanced plug.

Astral Acoustic uses quality Eidolic connectors and plugs From Double Helix Cables.
So you know they are excellent quality.

The Astral Acoustic Taurus IEM cable is obviously well made and smexy to look at by examining the many photos within this article.

I unscrewed the main jack connector and the insides were clean and well soldered and sealed.

Astral Acoustics Taurus IEM cable and Taurus 2.5mm to 3.5mm adapter 
with Echobox Explorer X1 and Campfire Audio Andromeda.
I loved this pairing very much.

The Astral Acoustic Taurus IEM cable is a copper cable that is focussed more in the bass to mid sections. 
The layering and imaging at times isn't as definite as a silver cable on some tracks.

When paired with a brighter source the cable seems to attain a synergy, each complementing the other.
It expands the sound scape as opposed to reducing its possibilities, the sound stage is wide, intimate and expansive.

When paired with a neutral or warm dap I found the lows to concentrate the sound more as opposed to creating a sense of the holographic, the sound stage can be medium and intimate instead of expansive.

I found the bass and lower mids to be prominent at times, and usually the vocals were forward.

I still found enough detail and top end to keep me satisfied.

At times the bass, is full and round and very pleasing on some tracks.

The Astral Acoustics Taurus series can certainly shine when matched with the right dap and earphone, the cable isn't as congested in the lower end as I have encountered with other copper cables. the Taurus has a nice shimmering top end, deep bass and warm mids with forward vocals.

with iBasso DX200 and Campfire Audio Andromeda.

I found the Opus#1 on high gain to be overly bright and coherent, but on mid gain to be acceptable with more bass and mids, yet not as coherent.

The ipod touch 6G was surprisingly a good match.

More TOTL daps such as the DX200 and Opus#2 were not as a good match to my ears and general preferences, as they seemed to desire a more transparent and neutral cable. Plus the Opus#2 can already be a bit thick at times in its lower regions.

The Opus#3 was not as bright as Opus#1, even, nice and with a sense of space, placement and dynamic. With more full thick bass. It had great imaging and matched well.

The Explorer X1 was very even with great separation.

-Tested with the ALO Audio Litz and Campfire Audio Andromeda.

The adapter cables provide a tight and secure fit. 
There is a slight sonic coloration to them in the lower end and mids.

-Tested with the Taurus IEM cable Campfire Andromeda.

Not as noticeable as with the ALO Audio Litz cable. Perhaps as in this case the Taurus IEM cable is doing most of the heavy lifting. Still a little emphasis on the lower end.

The Taurus adapter cables are consistent with the general signature that often comes with copper, although not as dark as other copper cables I have tested and listened to, it retains clarity and detail. 
The Taurus presents a top end sparkle.

They are not transparent adapters, but the coloration in the bass and lower mids is minimal.

The Astral Acoustic Taurus series of cables is not entirely typical of the sound one expects from a copper cable.
It doesn't have the slightly veiled sound one comes to expect from a copper cable, and exhibits a more detail, clarity and spaciousness.

Some might say its only wire and all cables sound the same, I doubt they have read this far.

The Taurus cable matches well to a brighter source imho. A neutral or warmer source loses some of the lower detail and overall clarity due to the extra low end..

It is not as transparent or clear across most frequencies as a silver cable might be. But some may love that depth to the low end.

Detail is fine, and it has a bit warmth in the lower end , and to some degree towards the mid sections.

Bass and vocals appear forward.
The layering is reticent.

The sound is more linear and flat, and less holographic.

With the adapters:
I detected a small amount of coloration in the bass and lower mids when paired with a silver cable.
They are adapters with a slight coloration to them. 
I also compared other companies adapters with the Taurus IEM cable and also with the ALO Audio Litz to confirm my findings.

The Taurus series of cables and adapters are for someone wanting perhaps to add a little something to the nether regions of the earphones, a touch it more intimacy, bass and mids.
I found the AA Taurus IEM cable when paired with a transparent adapter to match well for daps such as the iBasso DX200 and Opus#2.

They would pair well with a bright dap, or even a bass weak earphone, perhaps even increase the lower end on warm dap or earphone, If that be your fancy.

I found the Echobox Explorer X1 to be a good match with its Burr Brown Dac when using the Taurus series. The bass is faster and the sound is quite linear, detailed with excellent imaging and separation.  The Echobox Explorer X1 was very complementary and I hesitated a guess that the Opus#3 would exhibit similar results, which when listened to presented a lovely 3D-ish, dynamic and even experience with a decent full low end. 

The Astral Acoustics Taurus cable series is well constructed of excellent materials, like most cables its a question of matching the cable to right earphone and dap.
with the right pairing such as the Echobox Explorer X1 the taurus series certainly shines.
