Manual of product H2
Editorial note
The CoolBox H2 is an in-ear headphone that stands out for its wide sound range, from 80 to 20,000 Hz, ensuring an immersive listening experience rich in detail. Its built-in microphone, with a sensitivity of -42 dB, provides optimal audio quality for calls and recordings. Additionally, the rechargeable battery allows for up to 8 hours of communication, offering extended use without interruption. With Bluetooth 2.1+EDR connectivity, the CoolBox H2 facilitates wireless connection with a range of 10 meters, making it practical for everyday use. However, there are some drawbacks to consider. The Bluetooth 2.1+EDR connection, while functional, may suffer from latency with modern devices, which could be a friction point for demanding users. The 8-hour communication time may seem limited for heavy users, especially during long trips. Furthermore, the weight of 110 g may be perceived as relatively heavy, which could affect comfort during prolonged use. In terms of design, the CoolBox H2 has a modern and sleek appearance, but some users may find the in-ear headphones uncomfortable after extended use. Despite the NiMH battery technology, which may not offer the same performance as lithium-ion batteries, the product remains a good choice for those looking for an interesting value-for-money ratio, with useful features and an ergonomic design. In summary, the CoolBox H2 offers a satisfying audio experience and good value for money, but it is essential to consider its limitations, particularly in terms of connectivity and comfort for prolonged listening sessions.Score details
