A new masterpiece from legendary sound engineer Axel Grell
The name Axel Grell is no stranger to headphone enthusiasts. He is a legendary acoustic engineer who has worked in the high-end headphone industry for more than 30 years. Axell Grell has designed more than 50 headphones in his engineering career, ranging from entry-level to audiophile flagships. He not only has a very in-depth understanding of the tuning and production of advanced headphones, but also designed the HD580 and HD800 and other shocking audiophile headphones for Sennheiser, a well-known German audio equipment brand. The world's legendary headphone奇級頭戴式耳機。
In 2019, Axel Grell resigned as the chief headphone engineer of Sennheiser and founded Grell Audio. When he was a headphone engineer, he always hoped to use his own headphone production experience and the latest technology to create a variety of sound details. Headphones allow more users to directly understand what the music producer wants to express from the details of various instruments and vocals through headphones. Finally, in the fourth quarter of 2021, Axel Grell released the brand's first true wireless Bluetooth under the name of Grell Audio. Headphone TWS/1藍牙耳機 – TWS/1。

Patented NAR high-efficiency noise reduction technology
At present, many true wireless earphones on the market are equipped with active noise reduction function, and TWS/1 is no exception. Users can turn on the noise reduction function by tapping the left earphone for one second at any time. However, in order to fully realize the founder Axel Grell Strong adherence to the clarity and detail of headphones TWS/1 is not only equipped with the active noise reduction function that is common in today's wireless headphones, but also adds the most advanced Noise Annoyance Reduction (NAR) anti-sound interference technology to make noise reduction better than traditional noise reduction. Headphones are more natural and efficient機更自然及更高效率。
Axel Grell, who has extensive experience in headphone development, pointed out that the active noise reduction function concentrates on offsetting the low-frequency noise of the outside world, but at the same time it makes high-frequency noise more obvious. Therefore, Grell Audio has developed an exclusive NAR technology based on the theory of psychoacoustics. The frequency of the noise around the home is automatically adjusted. The reverse sound waves emitted by the active noise canceling function reduce the high-frequency noise received by the user when the active noise canceling mode is turned on, so that the active noise canceling function can not only focus on dealing with low-frequency noise but also offset it. Part of the middle and high frequency noise allows users to fully immerse themselves in their own music world without being disturbed by external noise，完全投入屬於自己的音樂世界。

High Fidelity Active Noise Cancellation Technology
In addition to the most advanced Noise Annoyance Reduction (NAR) anti-sound interference technology, Grell Audio also greatly strengthens the basic technology of TWS/1 in active noise reduction, making the noise reduction function of TWS/1 more practical and improving the user's noise reduction music experience.噪音樂體驗。
The principle of active noise reduction technology is to use the microphone and chip on the earphone to detect and analyze the ambient noise, and then play the low-frequency reverse sound wave with the same amplitude as the noise through the earphone to achieve the noise reduction effect. When the noise reduction function is used, the low-frequency band of the music will be occupied to send out reverse sound waves, which will weaken the low-frequency performance of the music.色與打開功能前不一致。
TWS/1, as a headphone that pays attention to detail, also adjusted the algorithm for the noise reduction function during development, so that the sound performance is not affected after the noise reduction mode is turned on, and the low frequency is still rich and powerful. When the user is in a noisy environment, such as On the street and in vehicles, you can fully enjoy the sound of a high-precision dynamic driver coupled with the legendary tuning of acoustic engineer Axel Grell所呈現的音色。

Well-built exclusive 10mm high-precision moving coil unit
Since there is an excellent noise reduction experience, the tone of the TWS/1 is even more important, so Grell Audio specially designed a dedicated high-precision 10mm moving coil unit for the TWS/1. The founder brings impressive and detailed tone to the TWS/1. As Sennheiser's headphone engineer, many of the headphones designed by Axel Grell are moving coil headphones. He knows the characteristics of the moving coil unit material and how it works. Therefore, the 10mm moving coil unit of TWS/1 is different from a moving coil unit. After careful adjustment and multiple tests, this 10mm moving coil unit can better present the details of high and low frequencies and the dynamics of the sound. Although TWS/1 is only equipped with one moving coil unit, it is based on Axel Grell's understanding of the moving coil unit and the quality of the earphones. Production experience A single moving coil configuration can bring the user's admirable sound performance置都能帶來令用家讚嘆的聲音表現。
Overall Tone The TWS/1 delivers a refined and vibrant sound in a large, defined soundstage plus a well-tuned and convincing message from impressive bass to clear highs, especially in the mids Rich and full of details and features, it completely restores the sound of the music, and each instrument can clearly present the overall performance. The dynamic and dynamic performance and control are very good.控制力都非常之優秀。
