Beyerdynamic DT 70 IE

Overview & Use Case

The Beyerdynamic DT 70 IE are designed for mixing and critical listening and belong to the new DT in-ear series. This range includes four models specifically tailored for musicians, sound engineers and stage performances. Their TESLA.11 drivers cover an immense frequency range and deliver exceptionally clear, low-distortion sound, even at high sound pressure levels of up to 137 dB. In addition, their ergonomic design ensures a comfortable fit and high sound isolation. This review looks at these and other technical features – and of course, how the DT 70 IE in-ears actually sound.

Impressive Accessories

All headphones in the DT in-ear series come with a small zippered soft case. Inside are five pairs of silicone ear tips in different sizes and three pairs of Comply tips. The memory foam adapts individually to the ear canal through body heat. A spare pair of cerumen filters is also included.

All models in the in-ear series are dust- and waterproof to IP68, except for the sibling model DT 71 IE, which meets IP65. This makes the series ideal for intense use on stage or in the studio.

High Protection and Quality Standards

The DT in-ear series, made in Heilbronn, maintains the high quality standards typical of Beyerdynamic. The detachable cable is Kevlar-reinforced, making it particularly robust and durable. Its MMCX connectors are gold-plated to resist oxidation and maintain conductivity over time. This connector type is also considered more robust than two-pin plugs. The cable ends near the in-ears are equipped with bendable wire to ensure a secure fit. At the other end, strain relief on the angled plug prevents cable breakage.

The in-ears themselves are semi-transparent with a smoky tint, subtly revealing their inner workings. Each earbud has a cerumen filter protecting the sound outlet from particles. Another mark of quality: the driver systems inside the in-ears are handmade and rigorously tested, ensuring low manufacturing tolerances.

Comfortable Handling of the Beyerdynamic DT 70 IE

At 1.40 m long, the cable is ideal for routing under clothing without excess slack, yet long enough to offer plenty of freedom of movement. The universal fit of the Beyerdynamic DT 70 IE can be customised with the included pairs of ear tips. Those preferring a more neutral, less bass-heavy sound will opt for the silicone tips, while those needing higher external noise isolation and stronger bass will favour the memory foam tips, which adapt perfectly to the ear canal and remain comfortable even during long sessions.

Thanks to the ergonomic shape, integrated bendable wire and a cable cinch on the Y-cable, the headphones fit not only comfortably but also securely. Beyerdynamic note that, due to their design, clicking sounds can sometimes occur during insertion – users should be aware of this so as not to worry about the functionality of their DT 70 IE.

Technically Prepared for Wireless IEM Receivers

The technical specs of the Beyerdynamic DT 70 IE promise detailed sound and high volume. The dynamic TESLA.11 drivers reproduce audio frequencies from an ultra-low 5 Hz to a super-high 40 kHz, far exceeding the typical human hearing range.

Their sound pressure level of 113 dB SPL is considerably higher than that of many competitors and makes them compatible with headphone preamps with low output power. Their impedance is just 16 ohms, enabling sufficient volume even when used with low-voltage headphone outputs. These characteristics make them ideally suited for use with pocket receivers of wireless IEM systems.

Balanced Sound – The Beyerdynamic DT 70 IE in the Sound Check

As with all headphones, sound is paramount – and the Beyerdynamic DT 70 IE are no exception. Their sound signature is balanced and largely neutral, making them highly useful for mixing and monitoring.

Bass and sub-bass are reserved and well-controlled, never overpowering other frequency ranges. The same goes for the treble and ultra-high frequencies, which remain precise, detailed and open while integrating smoothly into the overall sound profile. This gives space to the mids and ensures excellent speech intelligibility.

The DT 70 IE also deliver strong performance in terms of stereo imaging and subjective resolution, making them ideal for evaluating audio mixes. The stereo field is precise, with good depth placement, allowing instruments and vocals to be clearly differentiated. Their signal resolution is high, and transient reproduction is precise, as the signal remains uncompressed even at high volumes.

Finally, the Beyerdynamic DT 70 IE deliver low-distortion sound even at high playback levels. They also effectively shield external noise, making them suitable for judging output in loud environments. These headphones enable analytical audio assessment while still sounding musical – whether on stage, off stage or in the studio.

Conclusion

The Beyerdynamic DT 70 IE are well-balanced headphones that impress with their vast frequency range, distortion-free sound, controlled bass, finely resolved treble and detailed mids. Strong noise attenuation and excellent comfort round off the package, making the DT 70 IE a great choice for mixing and monitoring in loud stage environments.

Handcrafted in Germany, the Beyerdynamic DT 70 IE come with a comprehensive accessory kit. The reinforced Kevlar cable with bendable wire and gold-plated connectors is especially noteworthy. Their technical specs also make them perfect for use with pocket receivers in wireless IEM setups. Sound engineers, musicians and audiophiles seeking a neutral in-ear sound with good value for money will find much to appreciate in the Beyerdynamic DT 70 IE.
