Manual of product MDR-RF985RK
Editorial note
The Sony MDR-RF985RK headphones stand out with their impressive battery life of 25 hours, allowing for extended listening without interruption. Their sound quality is also remarkable, thanks to dynamic drivers and a polyethylene terephthalate diaphragm that provide rich sound reproduction, ideal for audiophiles. The in-ear design ensures good comfort during use, making these headphones suitable for daily use. Additionally, the hybrid nickel-metal rechargeable battery (NiMH) technology represents an economical and eco-friendly solution. However, some drawbacks are worth noting. The charging time of 3.5 hours may seem long for those who need quick use after a discharge. Furthermore, the weight of 300 g could become uncomfortable during prolonged listening sessions. Although wireless connectivity is an advantage, it does not support RF technology, which may limit compatibility with certain devices. Finally, the range of 45 meters may prove insufficient in large environments. In terms of performance, these headphones offer a quality audio experience, although connectivity limitations should be taken into account. The modern and ergonomic design is a plus, but the weight could be an issue for some users. Overall, the value for money is satisfactory, especially due to the battery life and rechargeable battery technology, but users should be aware of the restrictions related to connectivity and comfort.Score details
