Customer Review Summary
Introduction to the beyerdynamic DJ 300 PRO X
Released in February 2026, the beyerdynamic DJ 300 PRO X caters to DJs and audio professionals seeking robust, versatile headphones. Priced around £175, this model combines a closed-back, dual-design approach with precise audio reproduction, aiming to meet the demands of cueing and monitoring in various environments.
Design and Build Quality
The DJ 300 PRO X features a hybrid design allowing both on-ear and over-ear usage, supported by replaceable earpads supplied in both configurations. This flexibility serves DJs who value comfort for extended sessions and different monitoring preferences. The headphones are black, weighing a manageable 315 grams including cable, or 288 grams without. This weight aligns with professional headphones that require both durability and comfort.
The system is closed-back, effectively isolating sound to minimise leakage and external noise interference critical for club or studio settings. The dynamic driver is 45 mm, a size balancing sound staging and bass response.
Connectivity and Controls
Included is a detachable 1.5-metre special cable available in both spiral and straight forms, which can be connected either left or right side, adding practical flexibility for DJs on the move. The cable terminates in a 3.5 mm stereo mini-jack, standard for most audio devices, with a screw-on adapter to convert to a 6.3 mm jack, covering a broad array of professional DJ mixers and audio equipment.
Technical Performance
The headphones operate at an impedance of 48 ohms, providing a balance that enables compatibility with smartphones, DJ consoles, and other professional audio gear without requiring extensive amplification.
The frequency response range spans from 5 Hz to 35,000 Hz, extending well beyond the typical human hearing range, theoretically allowing detailed high-frequency reproduction and deep bass extension. The maximum sound pressure level reaches 117 dB, delivering ample volume for loud environments while maintaining audio clarity.
Beyerdynamic specifies two sound pressure levels, reflecting both the over-ear (109 dB at 1 mW and 117 dB at 1V) and on-ear (115 dB at 1 mW and 122 dB at 1V) modes, indicating a potent output capacity adapted to user preferences.
Comfort and Usability
The DJ 300 PRO X’s circumaural and on-ear earpads allow users to select their preferred fit, which is a key factor for long-term comfort during performances or studio sessions. The replaceable cable and earpads underscore the product’s longevity and ease of maintenance.
A sturdy carrying bag accompanies the headphones, aiding transport and protecting the device when not in use, a practical addition for gigging DJs and touring professionals.
Conclusion
The beyerdynamic DJ 300 PRO X delivers a technically versatile headphone solution for DJs requiring both robust sound isolation and adaptable design. Its balanced impedance and wide frequency range support accurate audio monitoring across various devices. The interchangeable earpads and detachable cables distinguish this model by addressing comfort and practicality. Positioned competitively at £175, these headphones are a technically solid choice for professional environments prioritising sound precision and reliability.
