If you want open-ear Bluetooth audio for zoom calls, choose Monster Open Ear AC339; if you need a helmet-mounted headset for motorcycle calls and navigation, choose Deersights Motorcycle Helmet. Monster is the more natural fit for desk work and general listening, while Deersights is built around riding, with a microphone, helmet mounts, and glove-friendly buttons.
• Monster Open Ear AC339: Open-ear clip design, touch controls, and up to 40 hours of playback suit everyday listening and calls; the trade-off is that it has no noise control.
• Deersights Motorcycle Helmet: Helmet speakers, a boom microphone, and noise-reduction features are tailored to calls and navigation on rides; the trade-off is that it is a helmet-specific setup rather than a general-purpose open-ear headset.
• Monster is for people who want an open-ear option for desk calls, walks, or workouts.
• Deersights is for riders who need audio and hands-free calling integrated with a compatible motorcycle helmet.
Monster’s main distinction is its open-ear clip design. The earbuds sit around the ears rather than sealing the ear canals, so they leave a more open listening experience than conventional in-ear earbuds. That can make sense for someone moving between a laptop call and other tasks, or for a walk or workout where staying aware of nearby sounds matters. The listed touch controls cover calls, music, and voice-assistant functions, giving the user basic control without needing to reach for a phone.
For zoom calls, the appeal is straightforward: this is a Bluetooth headset-style listening option that can also handle calls, without the enclosed feel of an in-ear design. Its age-range description is “Kid,” so a shopper looking for a bluetooth kids headset for zoom calls may find the listing’s intended audience relevant. That label alone does not establish fit for every child, though; the sheet does not give sizing details. The battery claim is up to 40 hours, and a digital display indicates remaining charge, which may help users plan around a full day of calls, listening, and other use. It is also rated IPX6 water-resistant, useful for sweat or exposure to water jets as described in the product information.

Deersights Motorcycle Helmet: Who It's For
Deersights is designed to fit into a riding setup. The package includes a boom microphone, clamp mount, and adhesive mount, and the listed compatible helmet types include full-face, modular, and open-face helmets. Its 40mm helmet speakers are intended to deliver music, calls, and GPS directions through the helmet. Rather than serving as a general-purpose pair of earbuds, the system is aimed at someone who wants communication and navigation audio while riding.
Its call-focused features are particularly relevant to riders. The headset lists DSP and CVC noise cancellation to help reduce wind and road noise during calls, plus auto-answer that picks up an incoming call after 10 seconds. A button can activate Siri or Google Assistant, while large physical controls are described as usable with riding gloves. It can connect two smartphones at once, which is useful for someone who wants to switch between devices. The built-in 1000mAh battery is listed for more than 25 hours of music and talk time, with low-power alerts and a power-saving mode.
• Best for an open-ear design → Monster Open Ear AC339. Its clip-over earbuds leave the ear open rather than using helmet-mounted speakers.
• Best for motorcycle helmet calls → Deersights Motorcycle Helmet. It includes a boom microphone and mounting hardware intended for helmet installation.
• Best for a long listed playback figure → Monster Open Ear AC339. Its stated maximum is up to 40 hours, compared with more than 25 hours of music and talk time for Deersights.
• Best for riding controls with gloves → Deersights Motorcycle Helmet. Its large push buttons are specifically described as easy to use while wearing riding gloves.
• Best for calls with wind and road noise in the picture → Deersights Motorcycle Helmet. Its listed DSP and CVC processing is intended to reduce those sounds during calls.
• Best for two connected phones → Deersights Motorcycle Helmet. It can connect two smartphones and switch between them.
• Best for touch control across calls and music → Monster Open Ear AC339. Its touch controls are described for call handling, music, and voice-assistant functions.
• Best for a desk-and-workout mix → Monster Open Ear AC339. Its open-ear clip design and water resistance suit more everyday settings than a helmet-focused installation.
Start with where you will wear the product most. If the headset is going to live in a motorcycle helmet, Deersights has the more relevant design: speakers, microphone, two mounting options, and physical buttons intended for gloved use. Check that your helmet type matches one of the listed options—full-face, modular, or open-face—and consider whether you want to install a headset rather than put on a standalone pair of earbuds.
For remote work, Monster is the more direct match between these two. Its open-ear format and call controls make it easier to picture at a desk, while the Deersights setup is built around helmet mounting. Still, the product information does not specify a dedicated computer connection, a particular video-call platform, or microphone performance for ordinary indoor calls. Bluetooth compatibility is listed for both, but a buyer should confirm that their intended device supports the connection they need.
Also think about your surroundings. Deersights, by contrast, describes call-noise processing for wind and road noise, but that feature is part of a riding headset—not a promise that it will block every sound in every setting. The products solve different problems, so a longer battery figure alone should not decide the choice.
If price affects your decision, check the current price on Amazon using the page’s button. I would compare that against the features you will actually use: a general open-ear headset for Monster, or helmet installation and riding-focused calling for Deersights. Neither one should be treated as a substitute for safe riding practices; the information here describes audio and control features, not a guarantee of safer riding.
I would choose Monster Open Ear AC339 for zoom calls and everyday listening because its open-ear clip design, touch call controls, and up-to-40-hour playback fit that mix better.
I would choose Deersights instead if motorcycle calls, GPS audio, and glove-friendly helmet controls are the priority.
In my opinion, Monster is the more versatile pick outside a riding setup, while Deersights is the clearer choice for someone who will install it in a helmet.
For zoom calls, I’d start with Monster unless the helmet use case is the deciding need.
It is a Bluetooth open-ear product with touch controls for calls, and the listed design may appeal to someone who prefers not to use sealed earbuds. The product information does not specify a particular video-call platform or computer compatibility, so check your device’s Bluetooth support.
It includes a boom microphone, auto-answer, and DSP and CVC noise cancellation intended to help reduce wind and road noise during calls. It is designed for installation in full-face, modular, and open-face helmets.
Monster lists up to 40 hours of playback. Deersights lists more than 25 hours of music and talk time, as well as low-power alerts and a power-saving mode.
Deersights lists DSP and CVC noise cancellation to help reduce wind and road noise during calls. Monster lists no noise control, so its open-ear design should not be treated as noise-cancelling.
