If you want an open-back headphone with a smooth, natural tonal balance that feels weightless on your head for long Zoom calls, choose Audio Technica Audiophile ATH-AD2000X; if you need a planar-magnetic driver system with extreme speed and the ability to drive complex musical details without compression, choose HIFIMAN HE600.
• Audio Technica Audiophile ATH-AD2000X: Delivers a warm, smooth sound signature with zero pressure on the ears due to its unique 3D Wing Support Housing; however, it is wired only and lacks active noise cancellation features.
• HIFIMAN HE600: Offers high sensitivity and rapid transient response using advanced planar magnetic technology in a significantly lighter chassis; yet, it requires a dedicated amplifier to reach its full sonic potential and lacks the passive isolation of closed designs.
• The Audio Technica pick is best for listeners who prioritize all-day comfort and a forgiving, vocal-centric sound profile.
• The HIFIMAN pick is ideal for audiophiles seeking maximum resolution and dynamic range who are willing to invest in proper amplification gear.
The Audio Technica Audiophile ATH-AD2000X is engineered for those who value a completely natural listening sensation above all else. At 0.6 kg, this unit utilizes a large-aperture 53 mm driver paired with CCAW voice coils to produce a frequency range spanning from 20 Hz to 20,000 Hz. What truly sets this model apart is the "3D Wing Support Housing," a vibration-proof mechanism designed specifically to distribute weight evenly. This design eliminates the clamping force often felt with heavy headphones, creating a feeling where you simply forget you are wearing them. If you are looking for the best sleep headphones for zoom calls or extended work sessions where physical discomfort is a dealbreaker, this open-air design ensures no sense of pressure builds up over time.
The sound profile here is defined by clarity and precise imaging. The use of a Permendur magnetic circuit and OFC7N voice coil allows for a smooth tonal balance that excels at reproducing vocals and instruments naturally. Because these are open-back headphones, they offer a wide soundstage that makes audio feel spacious and unconfined. However, this openness means they do not block out external noise, making them strictly for quiet environments. They connect via a standard 3.5 mm jack and operate at 40 ohms, which suggests they can be driven by many consumer-grade sources, though they will shine when paired with quality equipment. The ear pads are described as extremely comfortable, reinforcing the brand's focus on ergonomics for the adult listener.

You should buy the ATH-AD2000X if your primary goal is to enjoy music or take conference calls without fatigue. The leather enclosure and over-ear shape provide a secure fit, but the real selling point is the lack of ear pressure. It is the perfect choice for someone who wants best neckband headphones for zoom calls in spirit, even though this is an over-ear design, because the comfort factor is paramount. Conversely, skip this model if you need isolation from a noisy office or if you are looking for a portable solution that works well in moving vehicles. The open nature of the drivers also means you cannot wear these in public spaces where you don't want others to hear your audio leakage.
The HIFIMAN HE600 represents a significant evolution in planar magnetic technology, aiming to replicate the legendary sound signature of the HE6 while solving historical issues regarding weight and comfort. Weighing in at just 0.39 kg, this is a massive reduction compared to previous generations, achieved through a second-generation ergonomic headband and rotatable hinges. The core of its performance lies in the Neo Supernano diaphragm Gen.2, which is only 60% the thickness of the original. This ultra-thin diaphragm allows for incredibly fast transient response, meaning the headphone can start and stop sounds with pinpoint accuracy. With a frequency response stretching from 8 Hz to 65 kHz, it captures sub-bass rumble and ultra-high frequencies that many dynamic drivers simply miss.
Despite being a planar magnetic driver, the HE600 boasts high sensitivity of 94 dB and an impedance of 28 ohms. This combination is notable because it means the headphones are surprisingly efficient for their class, delivering sonic performance comparable to power amplifier-driven systems even when used with standard headphone amplifiers. The enhanced magnet structure uses rare-earth-free permanent magnetic materials, optimizing the design for reliability without sacrificing output. This makes it a compelling option for those who want high-fidelity sound without needing a monstrous, rack-mounted amplifier setup. If you have ever struggled with the ipx7 waterproof sleep headphones for zoom calls conceptually thinking about durability and weight, the HE600 offers a different kind of endurance—built to last with a plastic enclosure and robust internal components that have been refined over years of engineering.
This headphone is for the critical listener who hears every nuance in a recording. The open-back design provides a vast soundstage, allowing instruments to be placed precisely in space. However, the trade-off is that you must treat these with care regarding your audio source. While the 28 ohm impedance is lower than typical planars, the specific tuning requires an amplifier that can handle the dynamics cleanly. You should choose the HE600 if you are building a dedicated desktop setup and want to hear the absolute truth in your music files. Do not buy this if you are looking for a casual, "throw-on-and-go" solution, or if you need active noise cancellation, as the controls indicate there is none. The lack of active noise control means you are fully exposed to your environment, which can be a distraction during busy work hours unless you are in a controlled room.
• Best for all-day comfort and zero pressure → Audio Technica Audiophile ATH-AD2000X (due to the 3D Wing Support Housing).
• Best for detailed, fast transients and ultra-wide frequency response → HIFIMAN HE600 (thanks to the Neo Supernano diaphragm Gen.2).
• Best for driving efficiency without massive amps → HIFIMAN HE600 (28 ohms, 94 dB sensitivity vs. 40 ohms).
• Best for natural, smooth vocal reproduction → Audio Technica Audiophile ATH-AD2000X (smooth tonal balance and Permendur circuit).
• Best for lightweight portability within a desktop setup → HIFIMAN HE600 (0.39 kg vs. 0.6 kg).
• Best for users who hate ear pressure during long meetings → Audio Technica Audiophile ATH-AD2000X.
• Best for bass extension down to 8 Hz → HIFIMAN HE600 (extends well below the human hearing threshold).
• Best for a "forgiving" sound signature → Audio Technica Audiophile ATH-AD2000X (smooth, less fatiguing).
In my opinion, for a user specifically setting up a station for zoom calls, the Audio Technica Audiophile ATH-AD2000X is the superior choice. The reason is simple: the 3D Wing Support Housing creates a level of comfort that allows for hours of speaking and listening without the headache or ear pain that often accompanies heavy, high-performance gear. While the HIFIMAN HE600 offers incredible detail and a wider frequency range, the sheer weight difference and the need for careful amplification make it less practical for daily communication tasks where comfort is the primary constraint. I would buy the Audio Technica model because it prioritizes the human element of the experience—the feeling of the headset—over raw technical specs, ensuring you stay focused on the conversation rather than your gear.
Neither model features active noise cancellation, so both rely on passive isolation which is minimal in open-back designs. They are best used in quiet home offices or studios where background noise is low.
While the HE600 has a relatively low impedance of 28 ohms and high sensitivity, planar magnetic drivers generally benefit from a dedicated amplifier to deliver their full dynamic range and clean sound.
The Audio Technica ATH-AD2000X weighs 0.6 kg, whereas the HIFIMAN HE600 is significantly lighter at 0.39 kg, thanks to its updated ergonomic headband and reduced mass design.
