Beyerdynamic DJ 300 Pro X

Manufacturer: Beyerdynamic

The Beyerdynamic DJ 300 Pro X is a wired headphone designed for attentive listening sessions, built around a solid over-ear and on-ear fit that suits extended wear. It features a foldable construction alongside a detachable, tangle-free cable measuring 1.5 metres, making it reasonably straightforward to pack away and transport. The closed-back design contributes to passive noise reduction, keeping outside sound from interfering during use.

On the technical side, the DJ 300 Pro X uses a 45 mm driver unit with an impedance of 48 Ohms and a sound pressure level of 109 dB/mW. Its frequency response stretches from 5 Hz up to 35,000 Hz. The headphone includes a rechargeable battery with a battery level indicator, though the battery is not user-removable. Connectivity is strictly wired, with no microphone, inline controls, or wireless functionality present.

Pros
  • Foldable design with a detachable, tangle-free cable makes it practical to store and carry
  • Passive noise reduction helps block ambient sound without relying on electronics
  • Wide frequency range from 5 Hz to 35,000 Hz covers a broad sonic spectrum
  • Battery level indicator lets users keep track of remaining charge at a glance
  • Closed-back construction contributes to a more focused listening experience
Cons
  • No microphones means it cannot be used for calls or voice communication
  • Lacks active noise cancellation, relying solely on passive isolation
  • No inline controls or on-device control panel for managing playback
  • Does not support USB Type-C charging, and the battery is non-removable
  • No water resistance, limiting use in outdoor or high-humidity conditions
  • Wired-only connectivity with no wireless option available
Who is this for?

This headphone suits users who prioritize focused, distraction-reduced listening sessions, thanks to its closed-back design with passive noise reduction. Its foldable build and detachable tangle-free cable make it a practical choice for those who regularly transport or store their headphones. The broad frequency response and 109 dB/mW sound pressure level also make it a reasonable fit for users who want detailed audio reproduction across a wide sonic range, while the rechargeable battery with a battery level indicator appeals to those who value straightforward power management.

Who is this NOT for?

Users who need to take calls, participate in voice chats, or use their headphones for communication will find this product unsuitable, as it carries no microphones and cannot function as a headset. Those who prefer the freedom of wireless listening will also be poorly served, given its strictly wired-only connectivity. Additionally, users working in humid or outdoor environments should look elsewhere, as the headphone offers no water resistance, making it vulnerable to moisture exposure.

The Beyerdynamic DJ 300 Pro X is a straightforward listening headphone with no microphones, meaning it cannot be used as a headset for calls or voice communication. It lacks in-line controls, an on-device control panel, and in/on-ear detection for auto-pausing playback. Ambient sound mode is also absent, keeping the feature set focused purely on audio output.

Final Verdict

The Beyerdynamic DJ 300 Pro X is a wired, closed-back headphone that keeps its focus squarely on audio playback, offering a wide frequency response, passive noise reduction, and a practical foldable build with a detachable cable. Its 109 dB/mW sound pressure level combined with a 5 Hz to 35,000 Hz frequency range gives it solid technical credentials for attentive listening use. The absence of microphones, wireless connectivity, and water resistance does narrow its appeal, making it best suited to users who want a straightforward, transport-friendly headphone dedicated purely to listening — rather than a versatile all-purpose audio solution.
