If you want open-ear awareness and a fit that leaves your ears uncovered for teaching, choose K KAIBOAUDIO Verse Plus; if you need active noise cancellation and longer listening time, choose Sony WH-CH720N-BLACK.
For teachers, the practical divide is straightforward: one keeps the listening experience open, while the other is built to reduce surrounding noise.
K KAIBOAUDIO Verse Plus vs Sony WH-CH720N-BLACK at a Glance
• K KAIBOAUDIO Verse Plus strength: Open-ear bone conduction design helps you remain aware of surrounding sounds. Trade-off: It has no noise control.
• Sony WH-CH720N-BLACK strength: Active noise cancellation, ambient sound settings, and up to 35 hours of battery life with noise canceling on. Trade-off: Its over-ear design covers the ears.
• Verse Plus suits teachers who want audio while remaining more connected to the room.
• Sony suits listeners who want to limit distractions, take hands-free calls, or listen for longer stretches.
• Both support multipoint pairing, so each can connect with two devices at once.
The Verse Plus is the more classroom-minded option if you want to listen without sealing off your ears. Its open-ear design uses bone conduction audio, leaving the ear openings uncovered. That can make it a sensible fit for a teacher who wants a podcast or audio between lessons while still being more aware of activity nearby. Open-ear listening does not mean every sound will always be clear, but the basic design prioritizes awareness rather than blocking the room.
The practical details are useful for a busy workday. The stated battery life is up to 10 hours, and a full USB-C charge takes 1.5 hours. Bluetooth 5.2 multipoint pairing lets you switch between two connected devices, such as a work device and a phone. Touch controls handle music and calls, while wearable detection is intended to pause or resume playback as the headphones are taken off or put back on.
I would consider the Verse Plus for teachers who value an open listening style, touch controls, and multipoint use more than noise cancellation or very long battery life. I would skip it if your priority is concentrating in a noisy staff room, commuting with fewer distractions, or listening for extended periods beyond its stated 10-hour maximum. It has no listed noise-control feature, so it is not the choice for shutting out classroom or travel noise.

The Sony is the stronger fit when you want control over how much of the surrounding sound reaches you. It uses active noise cancellation, and its Ambient Sound mode offers 20 adjustment levels. That gives you a choice between reducing distractions and letting more outside sound through. The over-ear design is a clear contrast with the Verse Plus: it covers the ears rather than leaving them open.
Battery life is the Sony's most obvious advantage on paper. It is listed for up to 35 hours with noise canceling on and up to 50 hours with it off. A three-minute quick charge is stated to provide up to 60 minutes of additional playback. Multipoint connection supports two Bluetooth devices at once, and beamforming microphones are used for clearer voice pickup during hands-free calls. The 30-millimeter dynamic drivers and DSEE processing are additional audio features, though the specifications alone do not establish how any particular listener will judge the sound.
I would choose the Sony for teachers who want a quieter personal listening space outside active classroom duties, or who need headphones for long stretches of music, calls, or travel. I would skip it when being aware of nearby voices and movement is the main priority. Ambient Sound mode can bring more outside sound into the listening experience, but it is not the same design as an open-ear headphone that leaves the ears uncovered.
• Best for open-ear listening in a classroom: K KAIBOAUDIO Verse Plus. Its bone conduction design leaves the ears uncovered, making it the more natural match when staying aware of the room matters.
• Best for reducing distractions: Sony WH-CH720N-BLACK. Active noise cancellation is its defining advantage, while the Verse Plus lists no noise control.
• Best stated battery life with noise canceling on: Sony WH-CH720N-BLACK. It is listed for up to 35 hours in that mode, compared with up to 10 hours for the Verse Plus.
• Best for a quick battery top-up: Sony WH-CH720N-BLACK. A three-minute charge is stated to provide up to 60 minutes of playback. The Verse Plus instead takes 1.5 hours for a full charge.
• Best for switching between a work device and phone: Either one. Both support multipoint pairing with two devices.
• Best for touch-based controls: K KAIBOAUDIO Verse Plus. Touch controls are specified for managing audio and calls without reaching for the connected device.
• Best for adjustable awareness settings: Sony WH-CH720N-BLACK. Its Ambient Sound mode has 20 levels, giving you a way to adjust how much surrounding sound comes through.
• Best for a teacher looking for “best sweat resistant open ear headphones for teachers”: K KAIBOAUDIO Verse Plus is the closer match, with an important caveat. It is described as water-resistant and open-ear, but the provided details do not specify a sweat-resistance rating. I would not treat that wording as a guarantee for heavy sweating or particular conditions.
Comfort also depends on the kind of fit you prefer. The Verse Plus sits open at the ears, while the Sony uses over-ear cups described as faux leather. The available details do not identify memory foam ear cushions for either product, so shoppers searching for “memory foam ear cushions headphone for teachers” should verify the exact cushion material before deciding. Neither product's listed information establishes that it is designed for sleeping, so I would not call either one the “best sleep headphones for teachers” based on these specifications alone.
My Verdict
I would buy the K KAIBOAUDIO Verse Plus for a teacher whose main priority is listening while remaining aware of the room.
Its open-ear bone conduction design makes it the more fitting choice for that specific daily need, and multipoint pairing adds practical flexibility.
The Sony is the better pick for noise cancellation and longer battery life, but those strengths do not outweigh the open design for my classroom-focused choice.
For teachers, I would favor the Verse Plus when awareness matters more than isolation.
For a teacher who wants open-ear listening and more awareness of the surrounding room, the Verse Plus is the closer fit. For reducing distractions during planning or personal listening, the Sony's active noise cancellation is the stronger feature.
The Sony has active noise cancellation, while the Verse Plus has no listed noise-control feature. The Sony also offers Ambient Sound mode with 20 adjustment levels, but that does not make its over-ear design equivalent to open-ear listening.
Which has longer battery life?
The Sony is listed for up to 35 hours with noise canceling on and up to 50 hours with it off. The Verse Plus is listed for up to 10 hours, with a full charge taking 1.5 hours; Sony's stated three-minute quick charge provides up to 60 minutes of playback.
