The Boult Audio Q uses an over-ear fit and a closed-back design with stereo speakers, providing a solid passive listening setup. It is built to fold flat, making it easier to pack away, though no travel bag is included. The headphone carries an IPX5 rating, meaning it holds up against sweat during use. Both the detachable and tangle-free cable design add to its day-to-day practicality, and the product is not specifically intended for children.
The Boult Audio Q uses a 40 mm driver unit and covers a frequency range of 20 Hz to 20,000 Hz. It includes passive noise reduction to help block out ambient sound, though active noise cancellation and spatial audio are not supported. The drivers do not use a neodymium magnet, and the headphone does not feature any form of immersive or three-dimensional audio processing.
The Boult Audio Q is powered by a built-in rechargeable battery rated for 70 hours of use, and it charges via USB Type-C. A battery level indicator is included so users can keep track of remaining charge at a glance. The battery is not removable, and the headphone does not support wireless charging or solar charging.
The Boult Audio Q supports both wireless and wired connectivity, with the wireless side running on Bluetooth 5.4 and offering a maximum range of 10 meters. AAC codec support is included, though advanced audio codecs such as aptX, aptX HD, aptX Adaptive, aptX Lossless, LDAC, and LDHC are not available. Additional wireless features like Bluetooth LE Audio, Auracast, fast pairing, and NFC-based pairing are also absent from the feature set.
The Boult Audio Q can function as a headset, supported by a noise-canceling microphone that helps reduce background noise during calls. Controls are handled through an on-device control panel, while an in-line control panel on the cable is not included. The headphone does not feature ambient sound mode or in/on-ear detection for automatic playback pausing.
