/PRZWT/SHENZHEN, March 6, 2024 - In recent years, open headphones have become more and more popular with the ARC sound arc of the first open headphones launched by the international intelligent acoustic brand Cleer, and major headphone manufacturers have followed the trend and launched their own open headphones. A closer analysis of this trend will reveal that this is mainly due to the unique design and open structure of open headphones, which allow natural ventilation of the ears and provide better comfort. However, many headphone parties who have not used Cleer, because of the poor sound quality of the bone conduction headphones, the stereotype of open headphones is still stuck in "open headphones do not have good sound quality"!
Bad sound quality with open headphones? That's past tense!
At the beginning of open earphones, the problem of sound quality was indeed inevitable. Until Cleer launched the Cleer ARC sound arc and its upgraded product ARC II sound arc in 2021 and 2022, it broke people's inherent perception of the sound quality of open earphones. Especially the Cleer ARC II sound arc, open smart earphones, once launched, quickly became a phenomenon product in the earphone market with the characteristics of no in-ear, no ear damage, comfortable and intelligent sound quality, and rushed to Douyin's "TOP1 list of popular earphones" after just half a year of launch. It redefines the sound quality standard of open earphones, and is even regarded as the ceiling of open earphone sound quality by many earphone enthusiasts!
So, how did the Cleer ARC II sound arc achieve such a breakthrough in sound quality?
Sound Quality Plug-in for Cleer ARC II Arc 1: Qualcomm S3 Audio Platform
If you want to ask about the sound quality of the Cleer ARC II sound arc, you have to mention - Qualcomm S3 audio platform!
Friends who know a little about the earphone circle should know that the Qualcomm S3 audio platform is a high-end audio solution launched by the chip giant Qualcomm. Its core technologies include high-performance audio codecs and advanced audio processing algorithms. In simple terms, the Qualcomm S3 audio platform is like a "super brain" to improve the sound quality of the earphones, providing excellent sound processing power and audio performance for the earphones.
The Cleer ARC II sound arc with Qualcomm S3 audio platform supports Snapdragon Sound, which provides two different levels of sound quality options. The first is 16-bit 44.1kHz CD-level lossless Bluetooth sound quality, which is equivalent to the sound quality level of traditional CD discs, allowing you to capture every little detail and rich emotional expression in music. Second is 24-bit 96kHz ultra-high definition Bluetooth sound quality, which is even more advanced than CD, providing higher resolution and wider dynamic range. Generally speaking, this ultra-high definition sound quality will only be used for professional-grade audio equipment, and it can be said to be a luxury configuration when used in open headphones. Under this kind of sound quality, the timbre of the instrument, the breathing of the singer, and even the emotional ups and downs in the music can be clearly captured, and every detail can be rendered more delicate, realistic, and vivid.
To achieve this, the Cleer ARC II Sound Arc integrates Qualcomm's Fast Connect mobile connectivity system, which supports the latest Bluetooth 5.3 standard and LE Audio audio features. The Bluetooth 5.3 standard provides faster data transfer speeds and longer connection distances. This means that the Cleer ARC II Sound Arc can transfer more data faster, while also maintaining a stable connection over longer distances. LE Audio, on the other hand, is a low-power audio transmission technology that provides higher-quality audio and more stable connections.
Coupled with aptX Lossless lossless audio decoding technology, the Cleer ARC II Sound Arc can transmit audio data at a Bluetooth transmission bit rate of up to 1.2Mbps, which almost reaches the limit of lossless sound quality transmission. As we all know, higher bit rate also means higher data transmission volume, which helps preserve more audio details. So this super-fast data transmission capability allows the headset to reproduce 16-bit 44.1 KHz CD-level lossless audio, making the open headset even comparable to some in-ear headphones in sound quality, breaking the previous situation where open headphones were difficult to compete with closed headphones in sound quality.
The sound quality plug-in of the Cleer ARC II sound arc 2: oversized dynamic coil + unique DBE dynamic bass enhancement technology, it is worth mentioning that, in addition to the industry-leading Qualcomm S3 audio platform, the Cleer ARC II sound arc also affects the sound quality performance of the diaphragm and algorithm has also made great efforts, using a larger 16.2mm large dynamic coil unit than ordinary earphones, which can bring a wider audio dynamic range and stronger bass extension. In short, the bass is fuller and more shocking. In addition, the Cleer ARC II sound arc also incorporates the DBE dynamic bass enhancement technology developed by Cleer Lab, which can dynamically adjust the bass effect in real time according to the volume, making the bass more accurate when the volume is low and the bass more powerful when the volume is high, perfectly compensating for the lack of low frequency caused by the open structure.
This combination brings the Cleer ARC II Arc to a new level of sound quality. Even with a wireless connection, you can clearly hear the details of each music note and enjoy a listening experience close to the original studio quality. This is undoubtedly a huge boon for headphone enthusiasts who like comfort and pursue sound quality.
Qualcomm S3 Audio Platform: A Touchstone of Headphone R & D Strength
Although the Cleer ARC II Sound Arc is the first open headset to be certified by Snapdragon, the process of combining the two is not simple. Even with the increasing competition in the open headset track, there are still very few open headphones that can be equipped with Qualcomm chips because of their high technical requirements.
Qualcomm chips are the world's leading semiconductor technology, and their integration, performance and stability are very high. To successfully install such chips in open headphones, not only must the problem of technical compatibility be solved, but also from the selection and matching of hardware, to the writing and debugging of software, to the overall integration and testing, every link needs to be carefully designed and strictly verified. This requires very high requirements for the audio technology foundation and technical development strength of headphone manufacturers, but any headphone manufacturer with a slightly lower R & D strength cannot hold back!
With the 27-year experience of its parent company, Guanxu Electronics, in the field of acoustics, and the accumulation of 1300 + technical patents (ranked seventh in the world), Cleer has successfully showcased the performance of Qualcomm's S3 audio platform to the greatest extent, making the Cleer ARC II sound arc successfully ranked in Douyin's "Top 1 on the list of popular earphones" in only half a year, becoming the leader of open smart earphones.
In addition, when it comes to sound leakage, Cleer also has its own solution. At the design level, the Cleer ARC II sound arc adopts an ergonomic design to ensure that the sound unit can accurately target the user's ear hole. This design not only improves the comfort of wearing, but more importantly, it ensures that the audio signal can be directly and efficiently transmitted to the user's ear, reducing the loss and leakage of sound. On the technical level, the Cleer ARC II sound arc introduces advanced directional sound transmission technology. This technology ensures that the audio signal is transmitted in a more concentrated and directional way, avoiding the sound from spreading around, so that the sound can be accurately transmitted into the ear like a spotlight. According to the evaluation of many headphone bloggers, only when the headphones are at 70% or higher volume and located in a quiet scene, can the sound leaked by the headphones be vaguely heard within a distance of half a meter, but in most daily scenarios (such as commuting, etc.), the headphones basically do not cause noise interference to others.
Overall, the Cleer ARC II Sound Arc has successfully broken the limitations of open headphone sound quality and refreshed our understanding of open headphone sound quality with its R & D strength and Qualcomm S3 audio platform and a number of advanced technologies. If you are also looking for an open headset with both comfort and good sound quality, then don't miss the Cleer ARC II Sound Arc!
