Sound quality

Sound quality description

In this review, I will be using the black umbrella L size among the standard eartips, driven by Antelope Audio Amari with an output impedance setting of 27.9 ohms.


The Audiosense DT300 is not recommended to be driven by digital audio players or high quality amplifiers with output impedance close to 0 ohm; the output at 0 ohm is warm and smooth, but lacks crispness and the overall sound is dull. It is recommended to select a model with an output impedance of 5 ohms or higher. As a result of detailed judgment in the evaluation scheme based on measurements in this blog, it is recommended to drive the DT300 with an output impedance of around 30 ohms.

Sound quality general comment
  • Original Sound Fidelity: A+
  • Recommendation: A
  • Personal preference: A+


The Audiosense DT300 is an Audiosense product with a lot of personality.


First of all, it has a tendency to change its sound quality depending on the amplifier or re-cable, and moreover, it doesn't sound very good when driven by a digital audio player or a high-quality amplifier. There is even a possibility that you may feel the sound is better when you listen to it on your smartphone or iPhone than on a digital audio player.


On the other hand, the DT300 properly driven with an output impedance of about 30 ohms not only has a good sound balance, but also produces a fantastic and elegant sound that is nostalgic, sweet, warm, and pleasant to listen to.


If you add more load from there, you will get a greater sense of range, but the high frequencies may become too tight.


The sound quality changes depending on the device connected to the earphones, and the sound you hear changes depending on the device.

General comment

The Audiosense DT300 is truly an earphone for real audiophiles, with a sound that changes depending on the cable and amplifier. Of course, it may not sound that bad when you listen to it on your phone or digital audio player, but if you devise a way to drive it, it will sound nostalgic, balanced, and beautiful. It has the potential to be near the top of Audiosense's brand history, but the problem is that it takes some effort to hear that sound. However, you can enjoy a variety of sounds with this one, and none of them are bad, so the more earphone enthusiasts will want to get this item.
