Manual of product Bluetooth Headset 450-04
Editorial note
The Sandberg Bluetooth Headset 450-04 stands out for its excellent audio quality with a frequency range of 20 to 20,000 Hz and a sensitivity of 100 dB, providing an immersive listening experience. Its in-ear design ensures prolonged comfort, ideal for long listening sessions. Additionally, the wireless connectivity via Bluetooth 3.0+HS allows for a quick and stable connection up to 10 meters, offering great freedom of movement. The impressive battery life of 11 hours in communication and 250 hours in standby ensures extended use without frequent recharging. However, some drawbacks are worth noting. The 4-hour charging time may seem long for users in a hurry. While the Bluetooth range of 10 meters is acceptable, it can be limiting in environments requiring a greater distance. Furthermore, the Bluetooth 3.0+HS technology, although effective, may pose compatibility issues with newer devices. Finally, while the omnidirectional microphone is convenient, it can pick up surrounding noises, affecting call clarity in noisy environments. Overall, the Sandberg Bluetooth Headset 450-04 offers good value for money, combining comfort, sound quality, and battery life. However, these few drawbacks should be considered for optimal use.Score details
