AudioSense has been on a roll lately, continuing with the release of the visually pleasing and technically sound flagship DT600 IEMs.

Thank you, AudioSense, for providing the DT600 IEMs for review.

The AudioSense DT600 are the latest flagship in the “DT” series of thier multi-BA IEMs. They have six high-performance balanced armature drivers, arranged within a 3D-printed, three-way sound tube acoustic chamber. In addition, the DT600 feature a hand-crafted colorful faceplate, which gives each and every unit a unique appearance.

There is a small gap between cable's MMCX male jack to the shell's MMCX female jack. This allows users to remove the cable easily by applying force through the nail in this small gap.
Bottom Line

From the moment I placed them in my ears, I was immediately hooked. With deep lows, crisp highs, and rich voices, the music has just the right amount of sharpness and the right tuning. I have become completely enamored with theDT600 and consider them my new dark horse, hidden behind more popular IEM choices and ready to jump over them.

Company Introduction

Beyond being located in Shenzhen, China, AudioSense remains elusive regarding its origins. There is no public information available on when or who founded the brand. Nevertheless, they are able to produce a very good range of IEMs for a very reasonable price.

The T800, for example, is an 8 BA driver IEM that costs less than USD$300. The T800 are comparable to products from of Fearless, BGVP, or TinHifi, some of the popular brands that are well-received by the audiophile community.

Technical Specifications

Packaging

The AudioSense DT600 are packaged within a medium-sized black box and come with a simple bundle of accessories.

In the box

  • AudioSense DT600 IEMs
  • Braided oxygen-free copper (OFC) MMCX cable with 3.5mm TRS unbalanced termination
  • Pelican-like carrying box
  • 9 pairs of silicone ear tips
  • 3 pairs of foam ear tips
  • Documentation

The case is sufficiently large, and it can hold the in-ear monitors, a balanced/single-ended adapter, and a USB-Key-sized DAC, such as the Lotoo PAW S1.

Cable

AudioSense treats the cable bundled with the DT600 with great care. It has excellent braiding, a silicon guide that does not crack, and it feels as good over the ear as it does in your hand. Additionally, the cable indicates orientation with red and blue ring labels on each MMCX plug.

The stock cable is neatly braided with durable heat shrink on the ear guides.

Design

On the official website, the AudioSense DT600 are advertised as “made of biological adaption resin”. After I digested that description term by term, I believe they are referring to skin-friendly resin. A durable resin which our skin can adapt to.

Like previous releases, the the bodies are 3D printed and topped with custom faceplates adorned with glitter and flakes. It is pretty fascinating how the light bounces off the faceplates, providing a unique appearance to the IEMs.

Compared to the majority of multi-BA IEMs, they are relatively small for a 6-driver, be it in the hand or ear. Compared to my DUNU Studio SA3, a semi-custom pair of IEMs, the DT600 feel more luxurious and premium.

Overall, the build quality of the AudioSense DT600 is excellent.

The MMCX connectors fit perfectly, the shells do not show any gaps, and once again, I am blown away by advances in 3D-printing. There are no ridges and no steps – just one smooth surface all the way around.

The IEM’s interior is visible through close inspection. There are no cables to mess with and no bubbles, just six Knowles drivers embedded in audio tubes, directly printed into the shell. The results are pretty impressive.

With daily use, the IEMs more than hold their own against minor abuse but I do not expect them to be as durable as the BQEYZ Spring II or Moondrop SSR which have metallic shells. Overall, they are an excellently made pair of IEMs, especially considering their price.

Internal

The DT600 use a three-way frequency crossover, with two BA drivers used for the bass, two for the midrange, and two for the treble. AudioSense claims they are designed for exceptional acoustic performance.

DT600 Sound

The sound quality of these IEMs is superb, even with a small DAC like the Abigail CX31993 HD Dongle or the Audirect Atom 2. I am blown away by their clarity and resolution. Each detail is easily discernible from the first listen. While the DT600 may lack the ultra-high definition of higher-end IEMs like the Nostalgia Audio Benbulbin, at less than USD$250, they are almost unbeatable.

The AudioSense DT600 are fairly sensitive to the audio source. Every upgrade along the chain makes a noticeable difference when listening. When I tested the IEMs with the Venture Electronics Odyssey HD, I found them slightly too V-shaped. With the Lotoo PAW 6000, my preferred DAP, the signature became flatter, and the soundstage became much more extensive.

It is critical that users select the proper audio source for the DT600.

Bass

The DT600 present full-bodied and warm bass. However, it might not be as powerful as, for example, the Campfire Audio Polaris II, which employs a powerful DD just for the low end. The advantage of balanced armature drivers is that they offer a level of delicacy and definition that dynamic drivers cannot match, for now, at least. In particular, that is true for transients, which are almost instantaneous on BA drivers regardless of the source.

There is much more emphasis on the sub-bass than on the mid-bass. In the sub-bass, there is a deep rumble that can go really low, making the DT600 particularly impressive for bass-heavy tracks. Conversely, the midbass is slightly lighter in its notes and less impactful in its punch.

The AudioSense DT600 impressed me both with thier natural sound and powerful bass. Additonally, there is a pitch-black background, which provides a striking contrast between the deep, organic bass and the mellow voices on the front ground.

For me, in terms of bass, they can be considered a pair of perfect BA-driven IEMs.

Midrange

In the midsection, the approach is linear and moderately forward; the upper and lower midrage have the same slightly elevated thickness. Even though the midrange has a warm timbre, it is reproduced with remarkable clarity. There is good articulation in both male and female vocals, and instruments such as the guitar and piano are well-detailed.

Generally speaking, I find I prefer mids that have a nice warmth, over a more bright sounding midrange.

The sound can always be adjusted by using wide bore ear tips if it is not suitable for you.
The carrying case is sufficiently large to house the DT600 and there is plenty of space for either another pair of IEMs or a small DAC.

Treble

The treble is clear and does not contain sibilants or harshness. Almost everything sounds full, even, and the layered sounds are perfectly distinct and never overpower one another. The DT600 are an excellent choice if your main concern is realism and accuracy, even on a moderate budget.

They provide crisp details and small notes without overpowering your ears. With a richness in the upper range that blends seamlessly with the bass, the DT600 are vibrant and lively, perfect for daily commutes.

Where to Buy

Conclusion

It is clear that the AudioSense DT600 are a pair of excellent IEMs in every respect.

From the moment I placed them in my ears, I was immediately hooked. With deep lows, crisp highs, and rich voices, the music has just the right amount of sharpness and the right tuning. I have become completely enamored with theDT600 and consider them my new dark horse, hidden behind more popular IEM choices and ready to jump over them.
