The OneOdio SuperEQ A200 uses an over-ear fit and weighs 285 g, keeping it reasonably manageable for extended wear. It features a foldable design, which aids portability, though no travel bag is included. The headphone comes with a detachable, tangle-free cable and uses a closed-back construction with stereo speakers. It is not designed for children, and it carries no water resistance rating, so exposure to moisture is not accounted for.
The SuperEQ A200 handles noise reduction on two fronts, offering both active noise cancellation (ANC) and passive noise isolation. Its 40 mm driver is backed by a neodymium magnet and covers a frequency range of 20 Hz to 40,000 Hz, with a sound pressure level of 118 dB/mW and an impedance of 32 Ohms. Spatial audio is not supported.
The SuperEQ A200 is equipped with a built-in 1000 mAh rechargeable battery that delivers up to 100 hours of playback, or 60 hours when ANC is active. Charging is done via USB Type-C and takes around 3 hours to complete. A battery level indicator keeps the user informed of remaining charge, though neither wireless charging nor solar charging is available, and the battery is not removable.
The SuperEQ A200 supports both wireless and wired connectivity, using Bluetooth 5.4 with a maximum range of 10 m and AAC codec support. Higher-tier audio codecs including aptX, aptX HD, aptX Adaptive, aptX Lossless, aptX Low Latency, LDAC, and LDHC are not available, nor is Bluetooth LE Audio or Auracast. Fast pairing and NFC-based pairing are also absent, so connections are established through the standard Bluetooth pairing process.
The SuperEQ A200 can function as a headset and features a six-microphone array with noise cancellation, supporting clear voice pickup during calls. It connects to up to two devices simultaneously via multipoint pairing, and an ambient sound mode lets users stay aware of their surroundings without removing the headphones. Controls are handled through an on-device panel rather than an in-line cable remote, and there is no mute function or in/on-ear detection for automatic playback pausing.
The SuperEQ A200 includes a removable microphone, giving users the option to detach it when it is not needed.
