The Soundcore Select 4 is engineered for high-humidity environments, utilizing a high-grade silicone gasket system to protect the internal PCB from steam-induced corrosion. Technical specifications include a full-range driver supported by a passive radiator for low-frequency enhancement. The power management IC is calibrated for an optimized current draw, resulting in a documented 20-hour runtime via the USB-C charging interface.
Connectivity metrics confirm the use of a Bluetooth 5.3 stack, providing increased signal stability and reduced latency compared to previous generations. The chassis is rated IP67, indicating high-integrity protection against dust and water ingress. While the unit lacks native Wi-Fi or Matter integration, it functions as a high-performance Bluetooth peripheral with an integrated strap for mechanical suspension.
Performance documentation indicates a mono output profile, which restricts the horizontal soundstage. Maintenance protocols suggest a fresh-water rinse following exposure to surfactants such as soaps or shampoos to prevent degradation of the acoustic mesh over the long-term lifecycle of the device.
For applications requiring a fixed, wired connection for desktop use, the Creative Pebble 2.0 serves as a valid alternative to the Select 4's battery-dependent wireless design. Comparative data for these diverse audio solutions can be referenced in the budget-tier acoustic hardware repository.
