Manual of product H309
Editorial note
The CoolBox H309 earbuds stand out with their in-ear design, providing optimal comfort and appreciable sound immersion. With a wide sound range of 20 to 20,000 Hz and a sensitivity of 116 dB, they ensure a high-quality immersive listening experience. The omnidirectional microphone, with a sensitivity of -58 dB, allows for precise audio recordings, which is an asset for users who wish to make calls or record voices. Battery life is also a strong point, with up to 8 hours of talk time and 90 hours on standby, allowing for prolonged use without frequent recharging. The wireless Bluetooth connectivity and USB port add flexibility of use, although the 10-meter range may be insufficient in larger spaces. However, the product has some drawbacks. The NiMH battery technology, while durable, could pose long-term battery life issues compared to lithium-ion batteries. Additionally, the 8-hour talk time may seem limited for heavy users. Finally, the Mini-USB connector, which may seem outdated, could make compatibility with other devices less convenient. Overall, the CoolBox H309 earbuds offer good value for money, but they could benefit from improvements in certain technical aspects to better meet the needs of demanding users.Score details
