Manual of product CD920
Editorial note
The Acme United CD920 headphones stand out for their exceptional sound performance, delivering clear and powerful sound thanks to a sensitivity of 105 dB and an extended frequency range of 20 to 20,000 Hz. This combination ensures an immersive listening experience, ideal for music lovers and regular users. The in-ear design also contributes to prolonged comfort, although this type of coupling may not suit all ear shapes, leading to discomfort for some users after extended use. Additionally, the 2.5 m cable length, while offering flexibility of use, can also pose tangling risks, especially during active movements. In terms of design, the black and orange model adds a modern and stylish touch, although this color choice may not appeal to everyone. Furthermore, the wired connectivity, while convenient, limits freedom of movement compared to wireless headphones, which can be a drawback for users seeking mobility. Finally, the value for money is generally satisfactory given the sound performance and design. However, it is important to remain cautious about listening volume, as high sensitivity can pose risks of hearing damage if the sound is too loud for an extended period. In summary, the Acme United CD920 represents a good choice for those seeking a quality audio experience, provided they are aware of the limitations related to their design and connectivity.Score details
