If you want a lightweight, spacious open-back headphone for focused webinar listening, choose Audio-Technica ATH-R70x; if you need a reference-focused headphone for analytical listening around your webinars, choose Sennheiser HD600. Neither is wireless or noise-cancelling, so I would treat both as listening tools for a quiet room—not as all-in-one webinar headsets.
• Audio-Technica ATH-R70x strength: A lightweight open-back design with breathable fabric earpads and aluminum honeycomb-mesh housings. Trade-off: It is wired and has no noise control.
• Sennheiser HD600 strength: An open-back, reference-oriented design built around a 42 mm dynamic driver. Trade-off: It is also wired, with no noise control.
• ATH-R70x connection: Its detachable, dual-sided locking cable is designed to maintain correct stereo orientation whichever way it is attached.
• HD600 connection: It uses a 3.5 mm jack and has a listed impedance of 300 ohms.
• Choose the ATH-R70x if light weight, long-wearing comfort, and a spacious presentation matter most.
• Choose the HD600 if you want an established reference-listening design and a 3.5 mm connection.
The ATH-R70x is the more compelling fit for someone who spends long stretches listening at a desk and wants an open, natural presentation. Its aluminum honeycomb-mesh housings are designed to let sound move freely, while its carbon-composite resin construction is intended to support detailed transient response. Audio-Technica also specifies high-efficiency magnets and a pure alloy magnetic circuit to reduce distortion and support extended high-frequency response.

Comfort is a practical part of the appeal. The listed weight is approximately 210 g without the cable, and the breathable fabric earpads and wing-support design are intended for prolonged wear. For webinar use, that combination may suit someone who listens to presentations, recorded sessions, or other audio in a quiet home office and values a lightweight fit.
Skip it if you need a microphone, wireless freedom, or noise cancellation. The ATH-R70x is wired, and its noise-control specification is none. Its listed impedance is 470 ohms, so I would also consider the audio source in your setup rather than assuming it will be an effortless match for every device.
The HD600 is aimed at listeners who want an open-back headphone for reference playback and careful listening. Its 42 mm dynamic driver and acoustically transparent earcup design are presented as part of a system intended to let sound expand freely. Sennheiser also describes a specialized acoustic silk element used to control airflow around the driver.
For a webinar listener, the HD600 makes sense if your priority is clear, focused playback in a quiet space and you also want headphones suited to music or studio-style monitoring. Its velour padding is described as comfortable for extended listening, and the listed weight is 9.1 ounces. The 3.5 mm jack gives it a straightforward wired connection.
It is not the choice for someone seeking a complete communications headset. The HD600 has no noise control and no wireless connection, and the supplied information does not list a microphone. Its 300-ohm impedance is another reason to check that your intended audio source is a suitable match.
• Best fit for long listening sessions where low weight matters → Audio-Technica ATH-R70x. It is listed at approximately 210 g without the cable and has breathable fabric earpads.
• Best fit for analytical, reference-oriented listening → Sennheiser HD600. Its design is specifically presented around reference playback and transparent reproduction.
• Best for a detachable cable with flexible attachment → Audio-Technica ATH-R70x. The dual-sided locking cable is designed to preserve stereo orientation whichever way it is attached.
• Best if a 3.5 mm jack is the connection you want → Sennheiser HD600. That connector is listed in its specifications.
• Best for a spacious open-back design → Either, with a slight design distinction. Both are open-back; the ATH-R70x specifically uses aluminum honeycomb-mesh housings, while the HD600 emphasizes acoustically transparent earcups.
• Best for webinars in a quiet room → Audio-Technica ATH-R70x if comfort and light weight lead; Sennheiser HD600 if reference-style listening is the priority. Neither is specified as a microphone headset.
• Best for blocking background noise → Neither. Both list no noise control, and open-back construction is not the right direction if you need isolation.
• Best bluetooth headset for webinars → Neither. Both are wired, so neither meets a need for Bluetooth freedom.
I would choose the Audio-Technica ATH-R70x for webinar listening in a quiet office because its low listed weight, breathable pads, and open-back design make a persuasive comfort-focused combination.
I would not mistake it for a communications headset: it is wired and has no listed microphone or noise control.
If reference playback is the main reason you are shopping, I would choose the Sennheiser HD600 instead.
For someone searching for the best headband headphones for webinars, my pick is the ATH-R70x when long-wear comfort matters more than analytical listening.
No. Both are wired and list no noise control. Neither is specified as a wireless or noise-cancelling headphone, so they are better suited to quiet listening environments than noisy calls.
The ATH-R70x has the lower listed weight at approximately 210 g without its cable, along with breathable fabric earpads and a wing-support design intended for prolonged wear. The HD600 has velour padding described as suitable for extended listening, but its listed weight is 9.1 ounces.
The HD600 is the more directly reference-focused option in the supplied product information. The ATH-R70x also has reference in its product description and emphasizes accurate, natural open-back sound, so either may suit careful listening; the HD600’s stated focus is more explicitly analytical.
The provided specifications do not list a microphone for either model. Both are wired, open-back headphones with no noise control, so if you need a built-in microphone, wireless connection, or help reducing background noise, these are not complete headset solutions.
