QCY Crossky R70 Open-Ear Wireless Headphones Hi-Res with LDAC OWS Earphones Bass Boost Bluetooth 6.0 Earhook Sport Earbuds 52Hrs

During extended use, the headphones perform stably. Several users mention that they adapt to the open design after a few days and then barely notice wearing them. The material contacting the ear is soft and non-irritating. However, some report that actual battery life is lower than the manufacturer claims — at 70% volume with active use, the battery depleted after approximately 6.5 hours instead of the promised 13 hours per charge. Occasional brief audio dropouts or left earbud desynchronization occur, though these can be resolved by placing them in the case and pressing the button.

Drawbacks are minimal. Some users noticed slight latency when watching videos and gaming. One earbud occasionally disconnects, which is a known issue with wireless earbuds. One review warns that the charging case can become excessively hot during wireless charging — using only the standard cable is recommended. The proportion of critical reviews (1–2 stars) is low at just 3.9%.
