The Zebronics Zeb Thunder Max uses an over-ear fit and weighs 190 g, keeping the physical footprint manageable for extended wear. Its foldable build makes it easier to pack away, though no travel bag is included. The closed-back design houses stereo speakers and pairs with a detachable, tangle-free cable for added convenience. With an IPX5 water-resistance rating, the headphone can handle splashes and light moisture without issue. It is not designed specifically for children, and the open-back design is absent, meaning the earcups form a sealed enclosure around the ears.
The Zebronics Zeb Thunder Max uses a 40 mm driver unit for audio playback and relies on passive noise reduction to limit ambient sound, rather than active noise cancellation, which is not supported. Spatial audio is likewise absent, and the driver does not use a neodymium magnet.
The Zebronics Zeb Thunder Max is equipped with a built-in rechargeable battery rated for up to 120 hours of battery life, and it charges via USB Type-C, which rules out both wireless and solar charging options. The battery is not removable, but a battery level indicator is on hand to help users keep track of remaining charge before it runs out.
The Zebronics Zeb Thunder Max supports both wireless and wired connectivity, with the wireless side handled by Bluetooth 5.3 at a maximum stated range of 10 m. None of the advanced audio codecs are supported, including aptX, aptX HD, aptX Adaptive, aptX Low Latency, aptX Lossless, AAC, LDAC, or LDHC, and Bluetooth LE Audio with Auracast is also absent. Pairing conveniences such as fast pair and NFC-based pairing are not available either.
The Zebronics Zeb Thunder Max can be used as a headset, backed by a single built-in microphone, and supports multipoint connectivity for up to two devices simultaneously. Controls are handled through an on-device control panel rather than an in-line remote on the cable. Ambient sound mode, in/on-ear detection, and a mute function are not part of the feature set.
