If you want a helmet-mounted intercom for motorcycle rides, choose ELIKIDSTO Motorcycle Helmet; if you need open-ear earbuds for an airplane, choose Monster Open Ear AC339. ELIKIDSTO brings two-rider communication, a boom microphone, and helmet-ready mounting; Monster offers a clip-over-ear design and up to 40 hours of playback. For air travel, Monster is the more natural fit, while ELIKIDSTO is built around riding.
• ELIKIDSTO’s biggest strength: Two-rider intercom, music sharing, and helmet installation options. Trade-off: Its design is tied to a helmet and riding use.
• Monster’s biggest strength: Open-ear clip fit and up to 40 hours of playback. Trade-off: It has no intercom feature or listed noise control.
• Choose ELIKIDSTO for a motorcycle helmet setup, especially if you want to communicate with another rider.
• Choose Monster for everyday listening when an open-ear fit matters, including travel and airplane use.
• Neither product lists active noise cancellation on the Monster side; ELIKIDSTO lists active noise cancellation and CVC/DSP noise reduction for its microphone.
ELIKIDSTO is a helmet Bluetooth headset, not a conventional pair of travel earbuds. Its central feature is two-way intercom for two riders, with a stated intercom distance of up to 550 yards. It also supports sharing music with another user and mixing music with calls or intercom. That combination makes sense for riders who want communication and audio to work within the same helmet setup.
The package includes a detachable boom microphone, a clamp-on base, and an adhesive base for different helmet installations. The controls are designed to be usable with gloves, and the headset can connect to two phones at once. It also lists automatic call answering, voice-assistant access, and IPX6 water resistance. For someone choosing a motorcycle communication system, those are practical features to weigh alongside the 30-meter Bluetooth range and 1000mAh battery.

Monster’s AC339 is an open-ear clip-on design. Rather than fitting inside the ear canal, it sits over the ear, which may appeal to people who dislike in-ear earbuds or want a less enclosed feel. The touch controls cover calls, music, and voice-assistant functions. The product information also describes an open design that leaves the ears more exposed to surrounding sound.
That open fit is a meaningful choice for airplane travel. It can suit a traveler who wants audio without sealing off the ears, but it is not the right pick if the priority is blocking cabin noise. The listed noise control is “None,” so there is no basis to treat the AC339 as a noise-canceling travel headset. It may work for listening to audio or taking calls, but the product details do not specify a dedicated boom microphone or a latency figure.
The clearest advantage on paper is battery life: up to 40 hours of playback, plus a digital battery-level display. It also has IPX6 water resistance and Bluetooth 5.4. Its trade-offs are just as clear: no listed intercom, no listed noise control, and no headphone jack. If your priority is a comfortable open-ear wearable for general listening, its design is more relevant than ELIKIDSTO’s helmet-specific hardware. If you want isolation for a flight, neither product’s listed features establish that as a strength.
• Best for two-rider communication → ELIKIDSTO Motorcycle Helmet. It supports two-way intercom and specifies a range of up to 550 yards.
• Best for music sharing between riders → ELIKIDSTO Motorcycle Helmet. It lists music sharing and the ability to mix music with calls or intercom.
• Best for an open-ear clip fit → Monster Open Ear AC339. Its over-ear clip design avoids the in-ear format.
• Best for listed playback time → Monster Open Ear AC339. It claims up to 40 hours, compared with more than 25 hours of music or talk time for ELIKIDSTO.
• Best for helmet installation → ELIKIDSTO Motorcycle Helmet. It includes clamp-on and adhesive mounting options, plus a boom microphone.
• Best for tracking remaining battery → Monster Open Ear AC339. Its digital display is described as showing battery level.
• Best for active noise control → ELIKIDSTO Motorcycle Helmet. It lists active noise cancellation and CVC/DSP noise reduction, while Monster lists no noise control. The stated features do not make either a substitute for dedicated airplane noise-canceling headphones.
• Best for a simple airplane listening setup → Monster Open Ear AC339. Its wearable clip design is less tied to a specific activity, though its open fit will not provide listed cabin-noise isolation.
The phrase “low latency earbuds for airplane” is worth considering carefully here. ELIKIDSTO lists audio latency of 250 milliseconds, but that is a stated figure for a helmet headset, not evidence that it is suited to watching video on a flight. Monster does not provide a latency figure in the supplied details, so I would not call it a low-latency choice either. If synchronized movie audio is essential, the available specifications do not settle that question.
The same caution applies to “best with mic over ear headphones for airplane.” ELIKIDSTO includes a detachable boom microphone, but it is made to mount with a helmet headset. Monster uses an over-ear clip design, but its listed details do not identify a boom mic or specify microphone performance. A shopper choosing for calls should distinguish between a microphone being present and evidence about how well it performs in a noisy cabin.
My Verdict
For an airplane, I would choose Monster Open Ear AC339 because its clip-on open-ear design is the more straightforward fit for travel, and its stated playback time reaches 40 hours. I would not choose it expecting noise isolation or confirmed low latency. For motorcycling, I’d pick ELIKIDSTO instead: its intercom, helmet mounting, and boom mic match that job far better.
The listed noise-control feature is none. The open-ear design leaves the ears less enclosed, but the provided details do not claim active noise cancellation or cabin-noise reduction.
Monster lists up to 40 hours of playback. ELIKIDSTO lists more than 25 hours of music or talk time and a one-hour charging time, making Monster’s stated playback figure longer.
ELIKIDSTO includes a detachable boom microphone and describes microphone noise reduction for clearer calls.
