Portable Bluetooth Noise-Cancelling Headphones

Product Specifications

Technical details and manufacturing context for Portable Bluetooth Noise-Cancelling Headphones

Definition

Portable Bluetooth noise-cancelling headphones are consumer electronic devices designed for personal audio enjoyment with wireless connectivity. They incorporate active noise cancellation technology to reduce ambient environmental sounds, creating an immersive listening experience. These headphones are manufactured at industrial scale using automated assembly lines for consistent quality and volume production. They serve as finished retail products for end-users seeking high-quality audio in various environments.

Key specifications include a frequency response of 20–20000 Hz, a 40 mm driver diameter, and an impedance of 32 Ω. The Bluetooth version is 5.3, and the charging time is 2 minutes for a full recharge. The device weighs 250 g and offers a battery life of 30 hours with active noise cancellation enabled. Active noise cancellation reduces ambient noise by up to -35 dB. The operating temperature range is -10 to 45 °C, and the IP rating is IPX4 (splash resistant) per IEC 60529. The charging port is USB-C, and the maximum input power is 100 mW to prevent distortion.

Materials used include ABS plastic, memory foam, polyurethane, neodymium magnets, and lithium-ion polymer. These headphones are intended for consumer use, providing wireless audio playback and noise reduction in various settings. For procurement or verification, always confirm model-specific values and standards with the legal manufacturer or supplier, as the listed parameters are reference ranges for the product category.

Working Principle

Digital signal processing analyzes ambient noise through microphones and generates inverse sound waves to cancel external sounds, while Bluetooth wireless technology transmits audio signals from source devices. The headphones use microphones to capture ambient noise, and the internal processor generates anti-phase signals to reduce unwanted sounds. Bluetooth 5.3 ensures stable wireless connection with compatible devices. The active noise cancellation system is effective in reducing low-frequency noise, such as engine hum or air conditioning, while allowing the user to focus on audio content. The device operates within a temperature range of -10 to 45 °C and is splash resistant (IPX4).
