If you want wired, high-resolution listening with active noise cancellation for the office, choose Audio Technica ATH-MSR7NC; if you need Bluetooth freedom and a stated 20-hour battery life, choose Sony Noise Cancelling. The Audio-Technica is the more straightforward fit for someone who wants a wired setup, while Sony makes it easier to move around without a cable. Neither is a waterproof model according to the available details, so I would not choose either for wet or sweaty use.
• Audio-Technica’s biggest strength: 45 mm dynamic drivers, a stated 5 Hz–35,000 Hz range, and active noise cancellation in a wired over-ear design. Trade-off: it is wired, with no wireless or battery-life information provided.
• Sony’s biggest strength: Bluetooth 4.1, active noise cancellation, and a stated battery life of 20 hours. Trade-off: wireless convenience comes with the need to manage battery life.
• Choose Audio-Technica if you prefer a cable, over-ear listening, and the listed driver and frequency-response details.
• Choose Sony if you want Bluetooth freedom for moving between a desk and other parts of an office.
• These are not waterproof picks: neither product’s listed features establish water protection.
The ATH-MSR7NC is an over-ear wired headphone with active noise cancellation and 45 mm dynamic drivers. Its listed frequency response runs from 5 Hz to 35,000 Hz, and its 3.5 mm jack makes the wired connection clear. For office listening, that setup may suit someone who works mostly at one desk and would rather connect by cable than rely on Bluetooth.
Audio-Technica describes the noise-cancelling design as using microphones on the tops of the ear cups to pick up surrounding sound, then generating a signal to counter it when cancellation is active. The product description says this microphone placement is intended to keep cancellation consistent despite head movement or wind. Side vents are also part of the ear-cup design, with the stated purpose of supporting the tuning without compromising sound quality. Those design choices are relevant if you want noise cancellation and audio features in the same wired headphone.

The trade-off is practical: a cable can get in the way if you regularly stand up, walk around, or switch between rooms. The available details do not list Bluetooth or a battery-life figure, so I would not choose it for a cable-free routine. Who should skip it: anyone who needs wireless listening or documented long battery life.
Sony Noise Cancelling: Who It's For
Sony’s MDR-1000X/B is an over-ear headphone with active noise cancellation and Bluetooth 4.1. It also has a 3.5 mm jack, giving it a wired connection option as well as wireless connectivity. For an office routine that includes walking away from the desk, taking a call-free break, or moving between rooms with headphones on, Bluetooth can be a useful difference.
The main trade-off is that wireless use depends on a charged battery. The listed 20-hour figure is useful for planning, but it still means battery management is part of the experience; the specifications do not say how long charging takes. Who should skip it: anyone who wants a strictly wired headphone and does not want to keep track of battery charge.
• Best for a desk-first wired setup → Audio-Technica ATH-MSR7NC. Its listed connection is wired through a 3.5 mm jack, which suits someone who stays near a computer or other audio source.
• Best for Bluetooth freedom → Sony Noise Cancelling. Bluetooth 4.1 makes it the clear choice if you want to move around without keeping a cable connected.
• Best for a stated battery-life figure → Sony Noise Cancelling. Sony lists 20 hours. The Audio-Technica details do not provide a battery-life figure.
• Best if you want large dynamic drivers specified → Audio-Technica ATH-MSR7NC. It lists 45 mm True Motion dynamic drivers, along with its active noise-cancelling design.
• Best if the wider listed frequency range matters to you → Sony Noise Cancelling. Its range is listed as 4 Hz–40,000 Hz, compared with 5 Hz–35,000 Hz for Audio-Technica. That difference alone does not establish which one will sound better to you.
• Best for keeping the connection simple at a fixed desk → Audio-Technica ATH-MSR7NC. A wired headphone avoids relying on Bluetooth or a wireless battery during listening.
• Best for switching between wireless and wired listening → Sony Noise Cancelling. It lists both Bluetooth connectivity and a 3.5 mm jack.
• Best for someone seeking comfortable headphones for office use → decide by routine, not by an unsupported comfort claim. Both are over-ear designs; the specifications do not establish which one will feel more comfortable on your head over a full workday.
Buying Considerations
For office use, start with how you expect to connect. If your headphones will stay plugged into a desk setup for most of the day, the Audio-Technica’s wired design may be a natural match. If your workday involves moving around while listening, Sony’s Bluetooth option gives you more freedom from a cable. Sony also lists a wired jack, so the choice is not simply between a cable and no way to connect.
The figures should be read as specifications, not as a complete prediction of sound. Audio-Technica lists a 5 Hz–35,000 Hz response and 45 mm dynamic drivers; Sony lists 4 Hz–40,000 Hz and a hybrid driver with an aluminum-coated LCP diaphragm. Those facts describe different designs, but they do not settle how either headphone will sound with your music, calls, or computer.
Neither set of details establishes water resistance. That matters if you are searching for the best waterproof Bluetooth headphones for office use: Sony has Bluetooth, but the provided specifications do not say it is waterproof. Audio-Technica is wired and also has no listed water protection. For either model, I would keep moisture out of the decision unless you can confirm a relevant protection specification.
Finally, do not assume either model is a “voice assistant sleep headphones for office” solution. The available details do not list voice-assistant support, sleep features, or a dedicated assistant control. They do list media or remote controls, but that is not the same as confirming voice-assistant compatibility. If those functions are essential, check the product details for explicit support before choosing.
I would choose the Sony Noise Cancelling for my office routine because Bluetooth and a stated 20-hour battery life give it a practical advantage when I need to move away from my desk.
If I expected to stay seated and wanted a wired connection, I would choose the Audio-Technica instead.
For office use, the key difference is not a claimed sound-quality winner; it is whether wireless freedom or a cable-first setup better fits the workday.
I would not buy either on the assumption that it is waterproof or has voice-assistant features, since those details are not established here.
FAQ
Yes. The Sony MDR-1000X/B lists Bluetooth 4.1, and it also has a 3.5 mm jack for wired connection. Sony lists its battery life as 20 hours.
Both list active noise cancellation. Audio-Technica describes microphones in the ear cups that detect ambient noise for its cancellation system, while Sony describes adaptive noise cancellation. The provided specifications do not establish that one cancels more noise than the other in every office.
Waterproofing and voice-assistant support are not listed for either product in the available details. Sony’s Bluetooth connection does not by itself establish water resistance or assistant compatibility.
