Manual of product 21659
Editorial note
The Trust 21659 is a headset from the brand Trust that stands out for its immersive audio experience, thanks to its in-ear coupling and closed acoustic system. These features ensure optimal sound isolation, allowing users to fully enjoy their music or calls. Additionally, its wired connectivity and 3.5 mm connector ensure compatibility with a wide range of devices, making it easy to use on a daily basis. However, the model has some drawbacks. Although the weight of 174 g is reasonable, it can become uncomfortable during prolonged use, especially during long listening sessions. Furthermore, wired connectivity limits freedom of movement compared to wireless models, which could be a disadvantage for some users. The frequency range of the microphone, limited to 30 - 16000 Hz, may also not meet the requirements for professional audio recordings. In terms of performance, the integrated control unit makes it easy to manage volume and calls, providing a smooth user experience. With a good price-to-quality ratio, the Trust 21659 positions itself as an interesting choice, although the lack of advanced features like active noise cancellation may make it less suitable for noisy environments. In summary, this headset is recommended for those looking for an affordable and effective audio solution, while keeping its limitations in mind.Score details
