If you want comfortable wireless headphones with active noise cancellation and long battery life for everyday listening as a nurse, choose SONY WH-CH720N; if you need a dedicated wireless in-ear monitoring system for a transmitter-based setup, choose VOXFULL Ear Monitor System. These serve different jobs: Sony is a Bluetooth over-ear headphone, while VOXFULL is an RF monitor system built around a transmitter and receiver.
• SONY WH-CH720N: Lightweight over-ear design, active noise cancellation, ambient sound settings, and up to 35 hours of battery life; the trade-off is that its over-ear shape may not suit someone looking specifically for compact, clip-on earbuds.
• VOXFULL Ear Monitor System: In-ear monitoring with a dedicated wireless transmitter, automatic pairing, and support for up to six receivers; the trade-off is a shorter stated battery life and a setup that is not described as Bluetooth.
• For everyday Bluetooth listening and calls: Sony is the more relevant fit, with multipoint pairing and beamforming microphones.
• For monitoring a transmitter’s audio feed: VOXFULL is the more relevant fit, with mono/stereo switching and a receiver-based design.
• Choose Sony for general personal listening; choose VOXFULL for a compatible monitoring setup.
The WH-CH720N is an over-ear Bluetooth headphone designed for listening, calls, and moving between quieter and noisier surroundings. Sony lists dual noise sensor technology and an Integrated Processor V1 for noise cancellation, plus adjustable Ambient Sound mode with 20 settings. That combination makes it the more natural choice if you want music or other audio in your ears while still having a way to let environmental sound through.
Its 192-gram weight and stated battery life of up to 35 hours stand out for long listening sessions. Quick charging is also useful when you realize the battery is low: Sony says a three-minute charge can provide up to an hour of playback. Multipoint connection lets it pair with two Bluetooth devices at once, while beamforming microphones support hands-free calls. For a nurse comparing headphones for breaks, commuting, or listening outside clinical duties, those are practical everyday features—not a substitute for workplace-approved communication or safety equipment.

VOXFULL’s M6S is a system, not simply a pair of Bluetooth earbuds. It includes a transmitter, a wireless receiver, in-ear headphones, a cable, and a 6.35 mm jack. The transmitter and receiver are designed to pair automatically after power-on. There is also a one-button option to switch between mono and stereo input, and the system uses a 2.4 GHz wireless connection with a 24-bit/48 kHz audio processor.
That setup points toward monitoring audio from a compatible source, such as a stage or rehearsal arrangement. One transmitter can work with up to six receivers, which may suit a group that needs to monitor the same feed. VOXFULL lists up to 10 hours of battery life in its feature information, while the product details list an average battery life of eight hours and a three-hour charge time. I would plan around the shorter figure when thinking through a long session, since the stated battery information is not fully consistent.
I’d skip VOXFULL if you want a straightforward Bluetooth headphone for a phone, general music listening, or hands-free calls. The sheet describes RF wireless connectivity and a transmitter-and-receiver system; it does not list Bluetooth, multipoint pairing, or call-focused microphones. It is also not presented as clip on earbuds for nurses. The in-ear design may look compact, but the system’s purpose is monitoring—not a general-purpose nursing accessory.
• Best for Bluetooth listening → SONY WH-CH720N. Sony lists Bluetooth connectivity and pairing with two Bluetooth devices at the same time. VOXFULL is described as an RF system with a dedicated transmitter and receiver.
• Best for noise cancellation while listening → SONY WH-CH720N. Its listed features include active noise cancellation, dual noise sensors, and adjustable ambient sound. The VOXFULL sheet does not describe a comparable everyday headphone noise-cancellation setup.
• Best for a transmitter-based monitoring feed → VOXFULL Ear Monitor System. It includes the transmitter and receiver, supports mono or stereo input, and pairs automatically.
• Best for longer listening between charges → SONY WH-CH720N. Sony states up to 35 hours. VOXFULL’s materials give two battery figures—up to 10 hours in the features and eight hours in product details—both well below Sony’s stated maximum.
• Best for group monitoring from one transmitter → VOXFULL Ear Monitor System. The system can pair up to six receivers with one transmitter, a specific advantage for shared stage or practice use.
• Best for hands-free calls → SONY WH-CH720N. Its beamforming microphones are described as helping pick up voices clearly. VOXFULL’s listed features focus on monitoring rather than calls.
• Best for someone seeking clip-on earbuds → Neither is a direct match. Sony is over-ear, while VOXFULL is in-ear; neither sheet describes a clip-on attachment.
• Best fit for a nurse who wants headphones for personal listening → SONY WH-CH720N. Its Bluetooth, ambient sound controls, call features, and longer stated battery life make it the more relevant of these two, though no waterproofing is specified.
My Verdict
I would choose the SONY WH-CH720N for a nurse looking for personal headphones for commuting, breaks, or general Bluetooth listening. Its over-ear design, adjustable ambient sound, call microphones, multipoint connection, and up to 35-hour battery life make it the more versatile everyday option.
I’d choose VOXFULL only when the actual need is wireless in-ear monitoring from a transmitter. They aren’t interchangeable products, and VOXFULL’s group-monitoring strength doesn’t make it a better everyday headphone.
For everyday Bluetooth listening, calls, and listening between tasks, Sony is the closer fit based on its listed features. Neither product is described as waterproof, and neither is specifically presented as a nursing headset or a clip-on earbud.
The provided specifications do not state that either product is waterproof. Sony is listed as Bluetooth; VOXFULL uses RF wireless connectivity, so it should not be treated as a Bluetooth alternative based on these details.
Sony is a Bluetooth over-ear headphone with active noise cancellation, ambient sound settings, and microphones for hands-free calls. VOXFULL is an in-ear monitoring kit with a separate transmitter and receiver, automatic pairing, and support for up to six receivers per transmitter.
Sony’s listed maximum is up to 35 hours, with a three-minute quick charge providing up to an hour of playback. VOXFULL lists up to 10 hours in its feature information but eight hours in its product details, so its stated battery life is shorter and less consistent.
