Manual of product KH 4223 BT
Editorial note
The AEG KH 4223 BT headphones stand out with their impressive standby time of 80 hours, ensuring prolonged use without the need for frequent recharges. Their wireless connectivity via Bluetooth, with a range of 15 meters, offers great freedom of movement while allowing a stable connection with various devices. Additionally, the in-ear design and binaural type ensure optimal sound immersion, making these headphones comfortable for long listening sessions. However, several points may raise concerns. The 8-hour talk time may prove insufficient for heavy users, thus requiring more frequent recharges. Furthermore, the NiMH battery technology, while durable, could lead to a decrease in battery life over time, especially compared to modern lithium-ion batteries. The in-ear design, which suits many, may not appeal to all users, with some preferring over-ear models. In terms of performance, the headphones provide satisfactory audio quality for calls and music, but their use is primarily focused on these two aspects, limiting their versatility. The built-in microphone facilitates calls, making usage practical, but it is important to note that the Bluetooth range may be affected in environments with obstacles. Overall, the AEG KH 4223 BT offers reasonable value for money, although they may not be suitable for all users, particularly those seeking extended battery life or greater usage flexibility.Score details
