For helmet use, the KZ Gale USB C is my pick: its low-profile wired in-ear design avoids bulky earcups and adds an inline microphone.
Linsoul is the runner-up for its detachable cable and balanced tuning, if a standard USB-C connection is not your priority.

Linsoul is the runner-up for its detachable cable and balanced tuning, if a standard USB-C connection is not your priority.
• Linsoul 7Hz — best for balanced wired listening; pick this if you want dual dynamic drivers and a detachable 0.78 mm 2-pin cable.
• KZ Gale USB C — best for a low-profile wired fit with calls; pick this if your device has USB-C audio and you want an inline microphone and controls.
• Xmenha Purple Kids — best for open-ear listening away from a helmet; pick this if wireless playback and awareness of surrounding sounds matter more than a tucked-in fit.
• AIAUXAI USB C Headphones — best for simple USB-C listening and calls; pick this if you want a wired mic, inline controls, and a storage bag.
The Linsoul 7Hz Elua Ultra is a wired in-ear monitor with two dynamic drivers in each earbud: a 10 mm driver and an 8 mm driver. Its tuning is described as balanced, with smooth bass, clear midrange, and crisp treble. That makes it an appealing option for someone who wants music and game audio without a deliberately bass-heavy sound.
Its sculpted in-ear shape and passive noise isolation may help keep the earbuds seated and reduce some outside sound. The cable uses a 0.78 mm two-pin connector and is detachable, so it can be replaced or upgraded rather than being permanently fixed to the earbuds. For ordinary use, that is a practical design detail if cable wear is a concern.
For helmet use, the in-ear form is more plausible than bulky over-ear headphones because it does not add an earcup around the outside of the ear. Still, the product sheet does not establish how it fits under a particular helmet, and the shape of the earbud may matter under pressure. I would check helmet clearance and comfort carefully before relying on it for a long ride. Its cable also needs a compatible audio connection; it is not a wireless model.

The main trade-off is that this is a wired monitor with a 2.5 mm jack listed in its specifications, not a USB-C headset with a built-in microphone. In my opinion, it is the better fit for someone prioritizing balanced sound and a replaceable cable over call controls or plug-and-play compatibility with a USB-C device.
The KZ Gale is a wired USB-C in-ear earphone aimed at gaming and music. Its low-profile design avoids the bulk of over-ear headphones, while its built-in DAC is intended to handle digital audio through the USB-C connection. For a helmet shopper, that compact format is the clearest reason to consider it.
The inline controls support play and pause, answering or ending calls, and voice-assistant activation. The product also lists two omnidirectional condenser microphones. Those details make it more useful for calls or gaming than a basic wired earbud without a microphone. Its sound-isolating in-ear fit may reduce some ambient noise, although that also means it does not offer open-ear awareness.
I would choose this for a compatible USB-C audio device and a preference for wired listening. The cable means there is no need to manage a wireless connection or recharge the headset, but it can still snag or get in the way. A USB-C port alone does not guarantee compatibility with every device, so it is worth confirming that the device supports audio through that port.
The main limitation is that its connector is USB-C, which will not suit every helmet setup or audio source. As with any in-ear model, comfort under a helmet depends on the fit and the helmet’s interior; the listed low-profile design is promising, not a guarantee. In my opinion, it is the strongest match here for a compact wired helmet setup when the device supports USB-C audio.
The Xmenha Purple Kids is a wireless open-ear headset for children, with Bluetooth connectivity and a small speaker built into its case. The open-ear design leaves the ear less enclosed than a conventional in-ear bud. That can be useful when a child needs to hear sounds around them, but it is not the same kind of fit as a compact earbud tucked inside the ear.
The listed Bluetooth range is 33 feet, and the battery life is stated as five hours, with a two-hour charging time. Each earbud weighs 0.3 ounces according to the product description. The case can also play audio as a portable Bluetooth speaker, giving the set a second listening mode for use away from the ears.
For helmet use, I would not put this ahead of the wired in-ear options. Its over-ear hanging shape could interfere with the space around a helmet, and the open construction does not provide the same noise isolation as a sealed in-ear fit. The product is described for children aged six and up, and the open design is more naturally suited to casual listening, walking, or other situations where hearing nearby sounds matters.
The trade-off is that open-ear listening gives up some isolation, and its wireless design requires charging. The stated five-hour battery life is a practical limit for longer outings. It may suit a child who wants music without fully covering the ears, but I would not choose it as a dedicated helmet headset.
The AIAUXAI USB C Headphones are wired in-ear earbuds with a USB-C connector, an inline microphone, and button controls. The silicone-tipped design is intended to isolate outside sound, while the built-in DAC and stereo drivers are described as supporting bass and treble detail. It is a straightforward option for calls, music, and everyday use with a compatible USB-C device.
The inline button handles listening controls, and the product description also specifies volume adjustment. A magnetic design lets the earbuds attach together around the neck when they are out of the ears. A storage bag is included, along with two pairs of ear tips. Those small details may help keep the cable and accessories together between uses.
The fit is in-ear rather than open-ear, so it is more suitable for someone who wants a compact earbud style. For a helmet, the lack of bulky earcups is a plus, but the listing does not provide information about helmet compatibility or the earbuds’ external shape. I would treat comfort beneath a particular helmet as something to verify, not assume.
Its main drawback is that the cable and USB-C plug limit where and how it can connect. It is not wireless, and the product sheet does not identify a detachable cable. In my opinion, it makes sense for someone who wants a simple wired USB-C headset with a microphone and inline controls, but the KZ’s specified dual microphones and gaming focus give it the edge for helmet-oriented use.

FAQ
They may be more practical than over-ear headphones because they do not use bulky earcups. Fit varies by ear and helmet, so check that the earbuds sit comfortably without pressure and do not interfere with a safe helmet fit.
The Xmenha Purple Kids model is wireless and uses Bluetooth. The Linsoul 7Hz, KZ Gale USB C, and AIAUXAI models are listed as wired.
It is an open-ear, over-ear hanging design, so it may be less convenient beneath a helmet than an in-ear model. Its wireless setup and awareness-oriented fit suit other listening situations better; check helmet clearance before considering it for that use.
For helmet use, I recommend the KZ Gale USB C if your device supports USB-C audio and you want a compact wired in-ear design with a microphone. Choose Linsoul instead if balanced tuning and a detachable cable matter more.
