Noxgear 39g: a wearable Bluetooth speaker that clips to clothing
The Noxgear 39g is a very small Bluetooth speaker designed to be worn rather than placed. The model name is its weight: the listing gives 1.38 ounces, which is 39 grams. It attaches with a magnetic clip that grips clothing or a bag strap, and the listing describes both a clip on and a magnetic mounting type. The body measures 1.46 inches deep by 3.78 inches wide by 3.98 inches high, and it is finished in black with a single 1 inch driver.
The intended use is specific. This is aimed at runners, cyclists, walkers and dog handlers who want audio without putting anything in or over their ears. Wearing a speaker on the chest or shoulder keeps hearing completely unobstructed, which matters on a road, on a trail at night or anywhere situational awareness is a safety issue rather than a preference. It is a different answer to the same problem addressed by open ear headphones such as the SHOKZ OpenRun Pro2, and each solves it with a different set of compromises.
Battery, waterproofing and stereo pairing
The listing states waterproof construction, which for a product worn outdoors in unpredictable weather is the feature that decides whether it is usable at all. Note that no ingress protection rating is published anywhere in the data, so the word waterproof appears without a number behind it. That is a meaningful gap, since the difference between splash resistance and submersion tolerance is exactly what an IP rating describes, and buyers who need one should look for it in the manufacturer documentation.
Stereo pairing is listed as a special feature, meaning two units can be linked to produce left and right channels. Worn on opposite shoulders, that produces an unusual result: an actual stereo image that moves with the body. It also doubles the volume available, which addresses the obvious limit of a single small driver outdoors.
Bluetooth range is given as 10 meters, which is standard, and a USB charge cable is included. A full warranty type is listed, which is worth noting on a product designed to be worn in the rain.
What a single 1 inch driver can and cannot do
Expectations should be set by physics rather than by marketing. A 1 inch driver in a 39 gram housing cannot produce low frequencies in any meaningful sense, and the listing describes a 1.0 channel configuration, meaning mono output from a single unit. What such a speaker does well is voice: podcasts, audiobooks, radio, navigation prompts and phone calls all sit in the frequency range a small driver handles. Music will be thin, and outdoors that thinness is compounded because there are no walls to reinforce the low end.
Wind noise is the other outdoor variable that no specification captures. A speaker worn on the chest of a moving cyclist is in the airflow, and above a certain speed the wind will simply overwhelm it. Runners and walkers are much less affected. Buyers wanting real music reproduction outdoors need a larger speaker, which is where a rugged portable such as the Altec Lansing HydraTrek or a clip on model like the JBL Clip 4 belongs, both of which trade wearability for driver size.
Highlights
- Extremely light at a listed 1.38 ounces, which is the 39 grams in the product name.
- Magnetic clip mounting for clothing, straps and gear.
- Waterproof construction listed for outdoor use.
- Stereo pairing between two units for left and right channels.
- Leaves both ears completely unobstructed for safety on roads and trails.
- USB charging cable included, with a full warranty type listed.
- Bluetooth with a 10 meter range and touch operation.
Things To Consider
The battery figures in the listing contradict each other. Battery Life reads 12 hours while Battery Capacity reads 10 hours, and Charging Time reads 3 with no unit attached, so it is not clear whether that means three hours or something else. The listing gives the runtime two different ways and provides no milliamp hour rating to resolve it. Assume the lower figure and treat the charging time as unconfirmed.
Sound leakage is total and unavoidable. A worn speaker broadcasts to everyone nearby, which makes it unsuitable for public transport, shared offices, quiet parks and any situation where other people would rather not hear the audio. This is the fundamental difference between a wearable speaker and open ear headphones, and it decides the purchase for many buyers.
The product is filed under portable line in speakers, which does not match a Bluetooth device with no line input described anywhere in the listing. Nothing in the data describes an auxiliary socket, and the connectivity protocol is given as Bluetooth only. Treat the category placement as a filing artifact rather than as evidence of a wired input, and confirm before buying if a cable connection is required.
Finally, a magnetic clip needs something to clip to. Thick winter jackets, backpack straps and running vests vary in how well they take a magnetic mount, and a speaker that detaches during a run is easily lost outdoors. Check the mounting against the clothing it will actually be worn on.
Who it suits
The 39g suits runners and walkers on public roads, cyclists at moderate speeds, dog handlers, hikers and anyone who needs both ears free for safety while still hearing audio. It suits podcast and audiobook listening far better than music, and its weight is low enough that it disappears in use.
It is the wrong purchase for anyone who wants full range sound, for use around other people who would rather not listen along, and for buyers who need a confirmed waterproof rating or a reliable battery figure. Those buyers should compare the larger and better documented options in the portable Bluetooth speakers category, or look at the open ear headphones category for a private way to keep the ears unobstructed. A compact rugged speaker such as the Bose SoundLink Micro shows what the same pocket space buys when wearability is not the priority.
