Audio-Technica is known for delivering professional-grade headphones, and the ATH-R70x is their flagship open-back model. Designed specifically for mixing and mastering, these headphones combine a neutral sound signature with an ultra-lightweight build and Audio-Technica’s signature “wing support” system for comfort. With a wide frequency response and 470 Ω impedance, they’re not aimed at casual users – these are tools for audio professionals. But are they worth the investment? Let’s find out.
Open-back, over-ear professional reference headphones
Large-diaphragm 45 mm drivers with rare-earth magnets
Frequency response: 5 Hz – 40 kHz
High 470 Ω impedance – requires proper amplification
Feather-light build at 210 g
Dual-sided detachable cable (auto left-right channel assignment)
The ATH-R70x prioritises function over flash. With a matte black minimalist finish, they don’t stand out visually but feel sturdy and professional. The dual-sided cable automatically assigns left and right channels, which is clever for studio workflows. At just 210 g, they’re incredibly light, which makes them comfortable even during all-day sessions.
The signature “3D wing support” headband is a divisive feature – some love it, some find it unusual. Combined with soft, breathable pads, it creates a feather-light fit that almost disappears on your head. For marathon mixing or mastering sessions, they’re among the most comfortable headphones available.
This is where the ATH-R70x truly excels. The sound signature is neutral and transparent, designed for reference listening. The open-back design delivers a wide, realistic soundstage, making it easier to place instruments and effects in a mix. Bass is tight and accurate, mids are clear and natural, and highs extend smoothly without harshness. They don’t add excitement – but they’re not supposed to. These are about accuracy, not colouring the sound.
As open-backs, they offer no isolation and leak sound freely. They’re unsuitable for tracking or noisy environments but perfect for quiet studios where critical listening is key.
The ATH-R70x is built for studio use, not travel. They don’t fold, and no hard case is included. However, the build is sturdy, the detachable cable design adds longevity, and replacement parts are available. Treated well, they’ll last many years in a studio setting.
Retailing around £260, the ATH-R70x sits firmly in the professional tier. While pricier than mid-range open-backs like the Sennheiser HD 560S, they deliver the accuracy and comfort expected from a flagship model. If you have the right amp or interface to drive them, they’re excellent value for serious engineers.
Yes – at 470 Ω impedance, these require a proper headphone amplifier or quality audio interface to reach their full potential.
They can be, but they’re tuned for accuracy, not fun. Bass lovers may find them too restrained for casual use.
The M50x is closed-back, portable, and bass-boosted, while the R70x is open-back, neutral, and strictly designed for mixing and mastering.
If you’re a mixing or mastering engineer seeking accurate, fatigue-free headphones, the ATH-R70x is an excellent choice. Their neutral sound, wide soundstage, and lightweight comfort make them ideal for long, critical listening sessions. They’re not portable, and they demand proper amplification, but in the right setup, they’re one of the best reference headphones in their class.
