Release time:2025-09-11
On November 2, 2025, Dengbao Road launched the Bluetooth noise cancelling portable speaker DBL Quiet Sound for commuting, office and other scenarios, innovatively integrating active noise cancelling technology and portable design, allowing users to enjoy pure music even in noisy environments. The single unit price is 1499 yuan.
DBL Quiet Sound is equipped with Dengbao Road's independently developed "doubly fed active noise reduction system", equipped with feedforward and feedback dual microphones, which can accurately capture environmental noise and release reverse sound wave cancellation. The noise reduction depth can reach 35dB, covering common noise scenes such as subways, buses, and offices. At the same time, it provides a "transparent mode" where you can hear the surrounding sounds clearly without removing the speaker, making it convenient to report stations during commuting and communicate with people during office hours.
