The world's first all-digital-driven wireless headset, the new product of the iron triangle is really different.

The Iron Triangle recently released a large wave of New Products in Shanghai. It was really a big wave. I didn’t know which one to start with. I just decided to take the DSR9BT and DSR7BT wireless headphones first. Let’s start talking about it. Why is this?
In this year's audio market, we have seen some very interesting phenomena. For example, in the revival of vinyl records, the vinyl record player quickly returned to people's field of vision. Hi-Res Audio is already the trend of future music production and playback, and each family is also Desperately launching products that meet the high-resolution audio standards, and more and more headphones with small yellow labels, even the wireless headphones that have been considered to have poor sound quality have begun to have a small yellow label blessing.
The DSR9BT and DSR7BT of the Iron Triangle are two wireless headphones that support Hi-Res Audio. They are equipped with aptX HD/aptX/AAC/SBC transmission protocol and use 45mm drive unit. Not only that, DSR9BT and DSR7BT are the world's first all-digital drive. Wireless earphones. The all-digital drive here means that all the digital voice signals are received from the signal to the voice coil. That is to say, there is no traditional digital-to-analog conversion process. The voice coil in the earphone directly receives the digital signal and sounds.
This is the Dnote digital processing technology. Some people may have questions. Isn't this all digital power amplifier technology? It's actually different. The difference between the two is that the digital amplifier converts the digital signal into an analog signal and then transmits it. To the voice coil; Dnote technology is that the voice coil receives the digital signal, and then pulls the diaphragm to emit an analog sound signal, which means that Dnote does not have any traditional DAC processing, can be seen as a full digital drive for headphones system.
Since digital processing has higher accuracy and controllability than analog processing, it can guarantee the voice coil to receive undistorted sound signals under all digital driving. Of course, this is theoretical. It requires a voice coil for headphones. Special customization, which makes the DSR9BT and DSR7BT unable to receive analog signals, because they can't handle analog signals. Therefore, when the headphones are out of power, they can't listen to music. When connected to a computer, they are also digitally transmitted through the USB cable. It can support up to 24bit 96kHz audio source playback.
The positioning of the iron triangle DSR9BT is higher than that of the DSR7BT. The former uses a high-purity 7N-OFC wound short voice coil with a four-core stranded structure. I listened to the sound quality difference between the two headphones at the scene, and the style difference is not very large. However, there will still be differences in the fineness of the DSR7BT. The sound of the DSR7BT will give you more enthusiasm and more suitable for pop music, because its style is slightly exaggerated, and the elements of various sounds are more passionate. The disadvantage is that the lower part is more vain. It doesn't mean there is no bass, but the bass is not deep enough to have depth.
In contrast, the sound of the DSR9BT is much more stable, the bass is dive, and the sound field becomes regular and tangible. The treble and vocals are not as rough and fierce as the DSR7BT, and become more refined and convergent. I think DSR9BT The sound is really in line with the level of a high-end HiFi headset. Of course, we have to look at the price, is it at a level that everyone can accept.
Placed next to the DSR9BT and DSR7BT in the audition area is SR9, which is also the product of the iron triangle. It is equipped with a 45mm drive unit, which can be changed in line design, and uses the A2DC port dedicated to the iron triangle. The AK380 AMP is matched with the sound effect. Amazing, very smooth sound texture, the vocal part is fine and translucent. For those who have a light taste like me, the bass is the right benefit, not over-rendered.
I also listened to a product belonging to the LS series LS400iS, a four-unit moving iron earphone that contains two woofer units, a midrange unit and a tweeter. The sound of this earphone is very special, its sound field Not as loose as the SR9, although it is an in-ear headphones, the sound field must have limitations, but the sound field of the LS400iS is very subtle, the positioning of the vocals is very strict, the density of the center is very high, and the background music is like being surrounded by your ears. The same. This is a very different sound, the Iron Triangle has positioned it as a headset that can restore the atmosphere of the scene, the sound will be more realistic.
The new products of the Iron Triangle are really many. In addition to the earphone products, a series of replaceable upgrade lines and a replaceable vinyl pickup are also available. Looking at the array of chorus arrays on the spot, it is very impressive. Spectacular. Unfortunately, today's new products have not yet announced the price, there are a lot of products, and there is an impulse to rob the scene.
