The AUT250 uses an over-ear fit and a closed-back design with stereo speakers, making it suited for focused personal listening. It can be folded for easier transport, though no travel bag is included. The detachable, tangle-free cable adds convenience when switching between wired and wireless use, and the headphone is not intended for children. Water resistance is not provided, so the design is best kept away from moisture.
The AUT250 uses a 40 mm driver unit and covers the full standard audible range from 20 Hz to 20000 Hz. It provides passive noise reduction through its closed-back construction, though it does not include active noise cancellation or spatial audio support. The drivers do not use a neodymium magnet.
The AUT250 is equipped with a built-in 1000 mAh rechargeable battery rated for up to 100 hours of battery life, and it charges via USB Type-C. A battery level indicator lets users keep track of remaining charge at a glance. The battery is not removable, and neither wireless charging nor solar charging is supported.
The AUT250 supports both wireless and wired connectivity, using Bluetooth 5.3 for wireless operation with a maximum range of 10 meters. No advanced audio codecs are available — aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, AAC, LDAC, and LDHC are all absent. Similarly, the headphone does not support Bluetooth LE Audio, Auracast, fast pairing, or NFC-based pairing.
The AUT250 includes a single built-in microphone and can function as a headset for calls. Controls are placed directly on the earcup, while an in-line control panel on the cable is not provided. Ambient sound mode and in/on-ear detection are not supported.
