What it is

The Noxgear 39g reimagines personal audio for the active user who finds earbuds isolating or uncomfortable. Weighing roughly as much as a single AA battery, this speaker disappears onto your clothing using a clever dual-attachment system that combines a spring clip with a neodymium magnet. Unlike traditional portable speakers that bounce during movement, the 39g stays anchored to collarbones or hydration vests, providing a personal sound bubble without blocking environmental noise. Constructed with an IPX7 waterproof rating, it handles heavy rain and sweat with ease. The physical buttons are tactile and large enough to operate with gloves, allowing for volume adjustments and track skipping without reaching for a smartphone. While it lacks the deep bass of larger bookshelf units, its clarity is optimized for podcasts and high-energy music during workouts, and the integrated microphone offers surprisingly clear voice calls for a device this size.

Ravvy AI insight

The 39g fills a specific niche between bone conduction headphones and handheld speakers by offering weightless attachment. Its primary value lies in the N52 magnetic mount which prevents the drooping common in other clip-on designs. For the best audio experience, mount it as close to the collarbone as possible to maximize sound projection toward the ears.

How to get the most out of it

Using the Magnetic Mount

Place the magnetic back-plate inside your shirt and the speaker on the outside. This creates a sandwich effect that prevents the speaker from bouncing even during high-intensity sprinting.

Ownership tips

tip

Optimal Placement

For the best sound quality, clip the speaker to your shirt collar or the strap of your backpack close to your ear. This allows you to keep the volume lower while still hearing your audio clearly.

care

Maintenance After Rain

If you use the speaker in heavy rain, ensure the charging port is completely dry before plugging in a cable. Wipe the exterior with a soft cloth to prevent mineral buildup on the buttons.

Frequently asked questions

Can other people hear my music?

Yes, since this is a speaker and not headphones, people within a few feet of you will hear your audio. However, at moderate volumes, the sound is mostly localized to the wearer.

Is it compatible with Siri or Google Assistant?

Yes, the speaker features a dedicated button that can trigger your phone's digital assistant. This allows you to send texts or check the weather hands-free.

How long does it take to fully charge?

A full charge typically takes about 2 to 3 hours. The LED indicator will change color to let you know when the battery is topped off.

Will the magnet fall off during a run?

The N52 neodymium magnet is very strong and designed specifically for high-impact movement. As long as the fabric isn't excessively thick like a heavy winter coat, it stays very secure.
