FAQs

What are its dimensions?

The 39g is 2.6” in length, 1.6” wide with a 0.9” depth (max) (and weighs only 39 grams or 1.4 oz.)

Won’t others around me get annoyed with my music?

When you wear the 39g near your neck and listen at a comfortable volume, others standing just feet away won’t even know it’s on. But if you want to blast it for an entire group, it’s got enough power to do that too. But in that case, you might not want to wear it too close to your head.

Is it waterproof?

Yes! IP-67 rated, meaning it’s fine to be splashed or submerged up to 3 feet. Though keep in mind that it won’t sound too great while it’s underwater.

How long does the rechargeable battery last?

Battery life varies based on the volume setting. At a comfortable volume with the speaker worn on your upper body, around 12 hours. At maximum volume, closer to 4 hours.

Why would I use the magnetic clip? How does it work?

The built-in magnetic clip gives you the freedom to wear the 39g practically anywhere on your clothing, not just on a collar or strap. This ability is especially handy with ¼ zip jackets and hoodies. Just slide the low-profile magnetic clip downward to remove, place it on the inside of your clothing, position the speaker over the magnetic clip and let them snap in to a secure fit.

Does it have internal storage?

No. Audio can only be played through the speaker from a source device using a bluetooth connection.

What else can this thing do?

The 39g has some additional functions that you might have missed in the product manual!

When a call is incoming, press the play pause button to answer the call, or HOLD the play/pause button to cancel an incoming call (send to voicemail).

While on a call, HOLD the Backward button (|<<) to mute the call (silence your microphone). HOLD again to unmute.

The following button combinations can be input while the 39g is idle (on but not actively playing media or connected to a call).

  • HOLD Play/Pause and Volume up (+) to hear the current battery level.
  • HOLD Play/Pause and Forward (>>|) to toggle the blue LED indicator on/off.
  • HOLD Play/Pause and Volume down (-) to forget paired devices.
  • HOLD Play/Pause and Backward (|<<) to disconnect from the currently paired device (does not forget the pairing).
