Cons : Degree of Sound Mode change depends on what transducer is used Neutrality might not match with certain transducers.
Rest assured that my impressions written in this review are my own personal thoughts and opinions and in no way influenced by outside parties. I am not an expert in this hobby nor claim to be an audiophile. I just love listening to music and am fond of writing articles. Introduction: Korean-Fi. Not a lot of talks regarding this wonderful segment. These were plugged to my Oppo Reno 4 and Asus X for the review.
Click to expand Preferred setup is DCT in low power. No hiss at all. Preferred setup is bypass in high power. Dynamic works wonderfully with this pair in low power. JPG 1. Last edited: May 13, What a dedicated little dac! Great sound, minor nitpicks. Cons : - Price close to hybrid wireless units - Loose fitting jacks. It looks like a face! All that separation ensures a dead quiet noise floor, and I haven't run into any cellphone interference either.
Filtering I mostly tested it on DCT and transparent modes. The effect is subtle, and only works for I asked Radsone exactly what the filtering does but haven't got an answer yet.
I don't know if it's a DSP separation rather than a straightforward eq. Regardless, the effect of DCT mode is a subtle emphasis of sub-bass, and perhaps some noise shaping welcome to the psychosomatic zone , I don't know about pre-ringing and so forth. The dynamic mode is a much clearer bump in lower regions, rolling into the lows, which I find to be a bit much for my preferences.
Although it makes visual sense to put the recommended default DCT in the middle, from a user experience point it is actually hard to set a tiny three way switch to the middle without looking. It might be better to swap it with the dynamic mode they could do this in firmware. Build and accessories Considering the price of the package approaching bluetooth cabable usb-c dacs, I will do some nitpicking in this section.
My biggest issue is with the 3. They are rather loose, which worries me for a dongle type device. I was trying to figure out if I was having sampling sync issues when I realized that my earphones had come unplugged by a hair. For this type of device, where the cables are inevitably going to bend and pull, I much prefer the snap-in-place, secure connection of the apple dac dongle.
The body is an unibody aluminum rectangular prism with a thin bottom cap. A bottom with a matching finish would feel more solid and offer some extra perhaps unneccessary shielding. Included in the package is a clear plastic sleeve and two adhesive mounting points that stick to the back of your host device for a tidy portable stack. I do like the design as the permanent mounting point is rather unobstrusive once you remove the dac.
It is a bit of a puzzle as to how you could have your earphones come out the top side and fit a usb-c cable loop in your pocket. For the most part, I find myself preferring the dac dangle out of my pocket rather than risk my usb-c ports. There is one usb-c—c cable and one usb-c—a Full size in the box.
The c-c cable is better built with an extruded usb-c connector sleeve rather than the loose fitting crimped one present on the a—c. The c-a cable itself is also stiffer and cheaper feeling with roughly molded strain reliefs. The color and line quality of their branding and logo don't match the c-c cable either. I think at this price, they should really include a better a-c cable.

More on that later. Packaging Quite standard, not premium but not cheap unlike some sporty Sennheisers for example. According to the card found in the box, there should be one more pair of foam tips.
It was not there. And very light. Regardless of the tips I tried, it's the sort of headphones that disappear in the ears, and I'm left with the music.
The provided tips are perfect. The surface is not perfectly smooth; there's a bit of friction, which helps to keep the earphones in place. For any other headphones, I prefer my custom silicone tips.
Here, I don't care. I did all my listening with kbps mp3 from Deezer with very basic gear. I haven't noticed any significant difference between the sources, apart from what any other headphones show as well e. The sound is slightly tip-dependent. I get a good fit and seal using the stock M sized tips, but I prefer to use my custom tips anyway from Custom Art.
With the stock tips, the height extension is lacking a bit. With the custom tips, it's okay. When writing this review, I'm using the stock tips for better objectivity, however. My first feeling about the sound was that it's pleasantly effortless. Whatever I threw at it, it sounds like it's no big deal. There's excellent clarity in low volumes.
The Mahler's first symphony starts with a quiet passage when different instruments sort of "whisper" to each other. Particularly the brasses are supposed to sound like we hear them from a distance and I get precisely this feeling. With more listening time, some peculiarities of the frequency response started to appear. Heights : Extended to the limit of my hearing with the custom tips, slightly rolled off with the stock tips I was just tested a week ago and I'm good to Good detail retrieval.
I can't hear any significant spikes in the heights. The heights are not emphasized. Mids : I think the mids are the dominant frequency. Decent details.
When I first listened to the HE, my thoughts were that it could be the recording I was listening to at the moment, but the upper mids have the most emphasis violins, oboe, flute. After two weeks of extensive listening, this feeling was confirmed many times, very strongly. In fact, the upper mids spike is much more prominent with other genres, particularly with heavy metal. The emphasis goes down pretty fast. Female vocals are quieter than snare drums or electric guitars.
The male vocals are even softer. While I wouldn't call the lower mids recessed, the super prominent upper mids overshadow them. This description might suggest that the IEMs sound thin. I wouldn't call this a problem. Bass : For me, the bass is the weakest part of the frequency response. Well extended.
Double basses are well audible. I'd consider the sub-bass almost adequate, but the mid and mainly upper bass is definitely subdued. That goes hand in hand with the quieter low mids.
Most noticeable with violoncellos or bassoons. Sounds natural and effortless, but I could certainly use more quantity. Tympani in an orchestra, for example, lack the impact we're used to from listening to live music. Sub-bass sounds better than mid-bass. Mid bass or upper bass is probably better on the Noble X, thanks to the quantity. It sounds more natural on HE, however. Try listening to Dvorak's 9th symphony; everybody knows the fourth movement:.
