Collaboration with Z Reviews

The Thunder is a joint project with the world-renowned audio reviewer Z Reviews (Zeos). With more than ten years of experience testing high-end audio products and a dedicated community of enthusiasts, Z Reviews contributed his expertise and distinctive sonic preferences to the development and design. True to the signature Z Reviews sound, the Thunder delivers a powerful, bass-heavy sound with deep, punchy lows. It appeals to bass lovers and music enthusiasts alike, infusing every track with energy, weight, and excitement.

10 mm Diamond-Like Carbon Diaphragm

The Thunder features an all-new 10 mm dynamic driver with a DLC (Diamond-Like Carbon) diaphragm. This latest generation increases the diaphragm’s stiffness and strength by applying a thicker graphite coating to a thinner PEEK layer. As a result, the diaphragm responds faster, distorts less, rebounds more quickly, and delivers excellent impulse response across the entire frequency range. This enables greater bass output that remains controlled and deep-reaching—ideal for anyone seeking a more powerful yet cleaner bass.

Tuning for Bass Lovers

The Thunder offers a true basshead tuning with a 16 dB bass boost that creates a subwoofer-like bass experience. It delivers a rich rumble in the ultra-low bass and lower midrange and brings out every bassline and kick drum hit. In addition to the deep sub-bass, the midrange is warm and rich, showcasing male vocals in every genre to their best advantage. Despite the heavy bass output, the DLC diaphragm keeps the bass under control across the entire frequency range, ensuring a clean, natural sound without boomy resonances.

Warm and Rich Mids

The bass-emphasized tuning naturally extends into the lower midrange, creating a warm, full-bodied presentation. Male vocals and bass instruments gain weight and richness, giving your favorite tracks more energy and presence.

Clear Vocals and Extended Highs

The precise tuning of the highs, with a peak at 2.8 kHz, ensures crisp, natural timbres for vocals and instruments. As a result, vocals remain in the foreground and aren’t overshadowed by the bass. Vocals sound clear and clean, and the well-extended highs bring out micro-details that sparkle even alongside the powerful bass. This maintains a balanced sense of clarity across the entire frequency range.
