Introducing Audio-Technica’s Next Gen Open Back Headphones: ATH-R70xa & ATH-R50x

Meet the Future

Debuting at NAMM Show 2025 and already available in stores, Audio Technica’s latest output features two premium open back headphones that form the new R-Series line of professional open-back models; the Audio Technica ATH R-50x, and the Audio Technica ATH R-70xa. While both headphones are engineered with professional use in mind, their features and performance will invariably make them attractive to casual listeners who appreciate premium sound quality. 

The ATH-R70xa serves as the company’s new flagship pair of professional open-back headphones, offering accurate reference sound for mixing, mastering, and content creation, making them ideal for studio professionals. With their precise stereo, surround, and immersive audio capabilities, they’re a perfect choice for those who require reliable, neutral sound for critical listening. 

The ATH-R50x, while also designed for professional use with its natural sound and expansive soundstage, might also skew towards casual sound enthusiasts, owing to its powerful bass and clear midrange, which are uncommon for open-back models. It is particularly suited for critical-listening tasks like mixing or mastering but would also satisfy audiophiles seeking high-quality, balanced sound for music enjoyment. 

 

Design & Build

The ATH-R70xa is designed with comfort in mind for long listening sessions. It features a lightweight construction, weighing only 270g, which makes it comfortable for extended use without causing fatigue. The ear cups are made from durable yet lightweight materials, with a magnesium alloy frame providing strength and stability while keeping the overall weight low. The ear pads are made from soft, breathable material, contributing to both comfort and sound isolation, ideal for professional environments where long hours of use are common.

The ATH-R50x is similarly crafted for long listening periods, offering a comfortable and lightweight design at 290g. It shares a similar material approach with the ATH-R70xa, including magnesium alloy construction for durability and minimal weight. The ear cups are cushioned with soft ear pads, ensuring comfort during extended listening sessions. Like the ATH-R70xa, it’s designed to provide a balance of sound quality and comfort for critical listening tasks.

The ATH-R70xa and ATH-R50x are both designed for professional use, offering premium sound and comfort with a focus on critical listening. The ATH-R70xa improves on the original ATH-R70x by featuring re-engineered drivers for stronger bass and clearer midrange, making it a more versatile tool for mixing and mastering. In comparison, the M50x, a closed-back model, is better suited for general use with a focus on noise isolation and enhanced bass but lacks the expansive soundstage and open-back experience of the R-Series. Both the ATH-R70xa and ATH-R50x are lightweight, comfortable, and designed for professionals, with the R70xa being a more advanced iteration of the R70x and the R50x offering a slightly different tonal balance for those seeking a natural sound.

 

Sound Performance

ATH-R70x Sound Performance: The ATH-R70xa offers a neutral and balanced sound signature, with deep, firm bass that is a subtle but noticeable improvement over the original ATH-R70x. The midrange is defined but leans towards a "polite" presentation, lacking forwardness but providing clarity. The highs are crisp and clear without being harsh, with a touch of airy brightness that doesn’t sacrifice focus. Its sound is often described as dry or clinical, which suits professional use but may feel too analytical for those seeking warmth or sweetness.

ATH-R50x Sound Performance: In comparison, the ATH-R50x combines the low-end punch of the ATH-M50x with the openness of an open-back design. It delivers a robust bass, though slightly less pronounced than the M50x, and has a "V-shaped" sound with a recessed midrange. While the midrange isn’t as neutral as the ATH-R70xa, it maintains good presence, especially in the high-mids. The highs are less detailed and open than the ATH-R70xa but have a crispness that adds definition in certain sources. The ATH-R50x offers a more dynamic, slightly colored sound compared to the more clinical ATH-R70xa, making it ideal for those who prefer a punchier, more energetic listening experience. 

Features & Technical Specifications: What's New?

The ATH-R70xa and ATH-R50x both feature large, custom-designed drivers with a wide frequency response of 5 Hz to 40 kHz, ensuring accurate, detailed sound across the entire spectrum. The ATH-R70xa uses 45mm drivers and has an impedance of 470 ohms, making it best suited for professional use with dedicated amplifiers, as it requires more power to perform at its full potential. 

In contrast, the ATH-R50x employs 50mm drivers and has a lower impedance of 50 ohms, making it more versatile and portable, as it can be driven effectively by portable devices like smartphones, although an amplifier will still enhance performance. Both headphones are wired, ensuring high-quality, uncompressed audio, which is ideal for critical listening tasks, but they lack wireless options. The ATH-R70xa is more suited for studio environments, while the ATH-R50x offers greater portability without sacrificing sound quality.

 

How Do They Compare to Previous Models?

The ATH-R70xa improves upon its predecessor, the ATH-R70x, by enhancing bass depth and extending the frequency response for a more precise and fuller sound. The R70x is known for its neutral sound signature, making it a popular choice for professionals in need of clarity and accuracy. However, the R70xa offers improved comfort for long listening sessions and refined sound, making it more versatile for extended use in professional mixing or mastering environments, with a slightly warmer tone compared to the R70x.

As an open-back headphone, the ATH-R50x is designed for critical listening with a more refined sound and improved imaging compared to previous models, such as the closed-back ATH-M50x (though the M50x remains popular with casual listeners and those on the go because of its portability and noise isolation). In contrast, the ATH-R50x offers a wider soundstage and a more natural, balanced listening experience, making it better suited for audiophiles and professionals looking for detail and clarity.

 

Conclusion

The ATH-R50x offers a more refined sound with better imaging and a balanced, natural tone compared to the punchy, bass-heavy ATH-M50x, which is closed-back and geared toward casual listeners. Meanwhile, the ATH-R70xa improves upon the ATH-R70x with deeper bass, a broader frequency response, and better comfort, making it more suitable for long professional sessions and mixing. Both models target different needs: the R50x for audiophiles and professionals, and the R70xa for critical, detailed listening in professional settings.
