Following the launch of the Iron Triangle in December last year, they launched a grand national tour audition. The second game is in Shanghai, and on March 19th at Bainaohui. The exhibits include SR9, DSR series, CKR series, LS series and other new products.
The most important new product is the DSR series of wireless Bluetooth headsets, the world's first all-digital wireless headset. The ordinary Bluetooth headset needs to undergo digital-to-analog conversion after receiving the signal, and then the sound is driven by the analog signal driving unit. However, the DSR series of the Iron Triangle directly uses the digital signal driving unit, and there is no digital-to-analog conversion process, that is, all-digital processing. The iron triangle calls it Dnote digital processing technology.
At the audition, the explainers of the Iron Triangle gave the principle of Dnote technology. It can calculate the digital signal to generate a modulated signal, respectively driving the four voice coils in the earphone, and then combining the sounds. To be more straightforward, the digital audio signal does have a conversion in the earphone, but it is not converted to an analog signal, but a digital drive signal that can only be recognized by an iron triangle earphone.
Since there is no digital-to-analog conversion process, theoretically a higher signal-to-noise ratio can be achieved and signal loss is minimized. In the actual audition, the iron triangle DSR9BT does show very good resolving power and dynamics. Although it is only connected to the iPhone, it uses aac code transmission instead of higher quality aptx-HD, but the thickness and momentum of the sound is still satisfactory, far more than the ordinary Bluetooth headset can retain the explosive power of music.
The Iron Triangle also defined its own positioning of the moving iron earphone series, including the E series, IM series and LS series. The E series is mainly targeted at the singer, the IM series is the stage monitor, and the LS series is the live monitor. For example, the LS400iS has a very obvious optimization in the surround sound effect, highlighting the presence of the background sound, creating a feeling of listening to music on the spot, and the disadvantage is that it requires a large thrust drive.
My favorite earplugs on this field are also CKR100iS, which has an excellent balance between lubricated vocals and heavy background sounds. It is not too weak due to vocal stimuli, and it is not too prominent. And weaken the voice. Not only has strong resolution, but also a rich density. And this plug is very good, you can get a great sound with the iPhone. The only fly in the ointment is that the treble is slightly dim, otherwise it will suit my appetite. If you are a voice control, presumably CKR100iS will be very suitable for you, and not very biased.
The CKR series headphones will be available in China soon, and the highest-end CKR100Is will cost more than 3,000 yuan, but it will not exceed too much. As for other headphones that are not yet available for sale in China, DSR series wireless headphones are also very interesting products, just hope to meet with domestic headphones players as soon as possible.
