If you want a close-back headphone with wired and Bluetooth listening for calls, choose HIFIMAN HE-R10D; if you need a lightweight, open-back reference headphone for focused studio work, choose Audio-Technica ATH-R70Xa. The HE-R10D has the more flexible connection setup, while the ATH-R70Xa is much lighter and built around a wired, open-back design.
For calls, I would start with the HE-R10D if Bluetooth freedom matters, but neither product sheet specifies a microphone. If clear voice pickup is essential, confirm the call setup before choosing either one.
• HIFIMAN HE-R10D: A close-back, over-ear design with wired and Bluetooth connectivity, plus support for several Bluetooth audio codecs; its 360 g weight and listed eight-hour battery life are meaningful trade-offs.
• Audio-Technica ATH-R70Xa: An open-back reference headphone weighing 199 g, with replaceable velour earpads and a detachable locking cable; it is wired-only and offers little isolation by design.
• Choose the HE-R10D if you want the option to move between wired listening and Bluetooth without changing headphones.
• Choose the ATH-R70Xa if low weight, an open-back presentation, and a long-session studio focus matter more than wireless convenience.
The HE-R10D is the more adaptable option in this matchup. Its close-back, over-ear design combines a dynamic driver with a topology diaphragm and a claimed frequency response of 15 Hz to 35 kHz. The package includes the Bluemini R2R Bluetooth module, which supports Bluetooth 5.0 and codecs including LDAC, aptX HD, aptX, AAC, and SBC. You can also use the detachable 3.5 mm cable, with a 6.35 mm adapter included.
That mix makes sense if you want one pair for desk listening and less constrained listening elsewhere. For calls, Bluetooth can make it easier to move around than a cable-bound headphone. Still, the listed features do not specify a microphone, so I would not assume the HE-R10D will handle voice calls on its own. Check what microphone or call setup you would need before treating it as a call headset.

The ATH-R70Xa takes the opposite approach: it is a wired, fully open-back reference headphone designed around a lighter build. At 199 g, it weighs substantially less than the HE-R10D. Its 45 mm dynamic drivers, metal-reinforced construction, and replaceable velour earpads suit someone who expects long sessions at a desk and values a straightforward cable connection.
The open-back design is a defining choice, not a minor detail. The product information describes unrestricted airflow intended to reduce internal resonance and support quick transient response. That makes the ATH-R70Xa a natural fit for focused listening, monitoring, or studio tasks in a quiet space. Its dual-sided, detachable locking cable is about 3 m long, and the package includes a 6.3 mm adapter and carrying pouch.
That same design rules it out for several common situations. Open-back headphones do not provide the enclosed listening experience of a close-back model, and sound can pass between the earcups and the room. The ATH-R70Xa is also wired-only, so it does not offer the HE-R10D’s Bluetooth option. The product information gives an impedance of 470 ohms, another detail to consider when matching it to your audio equipment. I would choose it for a stationary work setup, not as a portable wireless call companion.
• Best for Bluetooth flexibility → HIFIMAN HE-R10D. It supports Bluetooth 5.0 through the included Bluemini R2R module and also works with a detachable 3.5 mm cable.
• Best for calls when you need freedom from a cable → HIFIMAN HE-R10D, with a caveat. Its Bluetooth connection is useful for mobility, but the product information does not list a microphone. Confirm how voice pickup will work before buying.
• Best for a wired studio setup → Audio-Technica ATH-R70Xa. Its open-back format and long, detachable locking cable are aimed at desk-based listening and reference work.
• Best for lower weight → Audio-Technica ATH-R70Xa. It weighs 199 g, compared with 360 g for the HE-R10D.
• Best if you want several Bluetooth codec options → HIFIMAN HE-R10D. Its module supports LDAC, aptX HD, aptX, AAC, and SBC.
• Best for an open-back design → Audio-Technica ATH-R70Xa. Choose it when airflow and an open listening setup matter more than keeping sound enclosed.
• Best if you do not want to rely on a battery → Audio-Technica ATH-R70Xa. It is wired-only; the HE-R10D lists eight hours of battery life for wireless use.
• Best for a sleep-headphone role or a gaming headset for calls → neither is an obvious fit from the listed information. The HE-R10D is the more flexible choice for wireless listening, but neither sheet specifies a microphone or features tailored to sleep or gaming calls. Similarly, shoppers looking specifically for USB-C charging Bluetooth earbuds for calls should note that these are over-ear headphones, not earbuds, and no USB-C charging detail is provided.
My Verdict
In my opinion, I would choose the HIFIMAN HE-R10D for a buyer who wants one headphone that can switch between wired and Bluetooth listening. That flexibility is the more useful match for calls, provided you confirm the microphone setup first. I would choose the ATH-R70Xa instead for quiet, stationary studio work where its 199 g weight and open-back design matter more than wireless use. The right pick comes down to mobility versus a lighter, wired reference setup.
The HE-R10D has Bluetooth connectivity, so it is the more convenient option if you want to move around while listening. However, neither product sheet specifies a microphone, so neither can be confirmed as a complete call headset from the listed details alone.
It is an open-back headphone, not a closed listening design. The product information describes airflow through the earcups; it does not provide a noise-isolation figure. For a more enclosed style of headphone, the HE-R10D is the close-back option in this comparison.
The ATH-R70Xa weighs 199 g, while the HE-R10D weighs 360 g. That makes the Audio-Technica the lighter choice on the stated specifications, though fit and comfort can still depend on the individual listener.
Neither one is described as a pair of Bluetooth earbuds, and the supplied information does not specify USB-C charging. The HE-R10D includes a Bluetooth module and lists eight hours of battery life; the ATH-R70Xa uses a wired connection. If USB-C charging is a firm requirement, these specifications do not establish that either headphone meets it.
