Manual of product Hel Dolfin Duo
Editorial note
The CGV Hel Dolfin Duo stands out with its modern and elegant black design, which easily fits into various environments. With a signal-to-noise ratio of 75 dB, it provides satisfactory audio quality for daily listening, although audiophiles may seek superior sound quality. The 8-hour battery life during continuous playback is adequate but may prove insufficient for heavy users, requiring frequent recharges. In terms of connectivity, the product offers both wired and wireless options, which is convenient. However, the lack of RF connectivity may limit certain wireless features, potentially restricting usage flexibility. Although the 2-hour charging time is considered long compared to other models, the inclusion of a power adapter and a battery charger facilitates immediate use and recharging. Overall, the CGV Hel Dolfin Duo provides a positive user experience thanks to its design and features, but some limitations in battery life and connectivity may disappoint users looking for optimal performance.Score details
