Customer Review Summary
Introduction
The beyerdynamic DT-770 Pro Softskin Set has been on the market since August 2018, aimed at users requiring closed-back, circumaural headphones with reliable sound isolation. Retailing at approximately £145, this model presents itself as a professional-grade option, equipped with a 250 Ohm impedance and a comprehensive frequency response range. This review will examine the technical specifications and build elements to determine the product’s suitability for various applications.
Design and Build
The DT-770 Pro Softskin Set features an over-ear, closed-back design, which typically favours noise isolation and prevents sound leakage. The circumaural earcups are fitted with softskin earpads identical to those used on related beyerdynamic models such as the DT550 and DT880S, promising comfort for extended listening sessions. These pads include foam discs for further cushioning and come in black, matching the overall aesthetic.
With a total weight of 375 grams including the 3-metre coiled cable and 287 grams without, these headphones maintain a moderate weight that balances sturdiness and wearability. Although the cable is not replaceable, it features a coiled section to reduce cable tension and ends in a 3.5 mm mini-jack connector. The inclusion of a screwable 6.3 mm stereo jack adapter enhances compatibility with professional audio equipment.
Technical Specifications
- Impedance: 250 Ohms
- Frequency Response: 5 Hz to 35,000 Hz
- Sensitivity (Sound Pressure Level): 96 dB
- Max Sound Pressure Level: 96 dB
- Weight: 287 g (without cable), 375 g (with cable)
- Connector Type: 3.5 mm mini-jack with 6.3 mm adapter
The frequency range is notably wide, extending beyond the typical human hearing range, which may provide benefits in audio clarity and detail. The 250 Ohm impedance indicates that these headphones are designed primarily for use with external amplification or dedicated headphone outputs, as higher impedance requires more power to drive effectively.
Sound Signature and Performance Potential
The DT-770 Pro series is identified as having diffuse-field equalisation, a processing approach that aims to produce a neutral and balanced sound profile, suitable for detailed mixing and audio analysis. The dynamic driver technology paired with the closed-back architecture tends to offer good bass response while minimising external noise intrusion.
At a maximum SPL of 96 dB, these headphones can manage moderately loud listening levels without immediate risk of distortion, although users should be mindful of hearing safety at sustained high volumes.
Practical Considerations
- The 3-metre coiled cable allows movement without excessive slack, catering to studio environments or controlled listening setups.
- The inclusion of a drawstring bag with a label field facilitates storage and portability, adding to the accessory value of the package.
- The absence of a replaceable cable could be a limitation for long-term durability, as cable damage would require professional repair or replacement of the entire unit.
Conclusion
The beyerdynamic DT-770 Pro Softskin Set presents as a robust, technically competent headphone package with a focus on comfort and sonic precision. Its 250 Ohm impedance and wide frequency response make it suitable for professional and audiophile use, particularly in settings where sound isolation is key. While the lack of a replaceable cable could impact longevity, the overall build, including a coiled cable and screwable adapter, supports versatile usage.
At its price point, these headphones provide features aligned with monitoring and detailed listening, with an emphasis on natural sound thanks to diffuse-field equalisation. They represent a well-rounded choice for those prioritising ergonomic design and critical audio fidelity.
