Frequently asked questions

The speaker sends powerful vibrations into the surface it's attached to. The surface then resonates, propagating the sound waves (including bass) into the room, turning the surface itself into the speaker cone.

Simply power on two Speakers and pair them to your device simultaneously. They will automatically sync to deliver a 3D soundstage, separating audio into distinct left and right channels for a truly immersive experience.

The battery lasts about 3 hours with 1 hour charge with the included charging cable.

The unit has a built-in high-sensitivity microphone. Once connected via Bluetooth, pressing the call button activates the intercom function for hands-free calls or voice commands.

The best for helmets

I recently got these small, amazing speakers and decided to mount them on my helmet. I was absolutely blown away by the results. The sound quality inside the helmet is incredible—just like being in a car with the music turned up. The bass is so strong it feels like my jaw is going to drop. The genius behind these little devices is that when they’re attached to the helmet, the helmet itself becomes the speaker. All the subtle bass details and the overall sound are transmitted perfectly. I can’t believe how such affordable speakers deliver such outstanding performance. I highly recommend them to anyone who rides a motorcycle with a helmet or hits the slopes snowboarding. Just amazing.

Great vacation speaker!

This little gem was perfect for our vacay to Portugal! We used it in the AirBnB while we were getting ready and it’s surprising how much it projects once you put it on something! The auction did better when it was west of course and if I left it after we left it would fall off onto the floor but that’s to be expected. We didn’t take it outdoors with us so I don’t know how the sound is in that setting but for background music while we got ready, it was perfect. Also it’s so small and easy to pack! I charged it once but not because it was low - just thought I should. We used it every morning for a week and it held a charge for a long time!

Small size good sound

My daughter loves this tiny speaker. The sound quality is good for the size. She says it holds a charge really well. She enjoys using it on different surfaces to amplify the sound. I appreciate it as a 2 pack. Each speaker has its own charging cord, wrist cord, with optional suction cups and 3M tape. These are perfect for travel.

CRAZY Bluetooth!

These things are CRAZY! They feel like an ANGRY BEE in your hand and when you stick them to the wall, the wall becomes the speaker with base. For the price the sound is impressive. The only reason I gave a 4 star and not a 5 is because they dont come with a hard case to store them in.

Pack a punch but they have a catch.

Gave it a 5 star since they are very affordable and come in pairs. They are just as good or even better than my JBL Go 3. The only catch is if you want to actually have a good speaker experience you will need to use a card board box. I used the one from the package 📦 I'm so pleased I even order a 2nd pair. They are way louder than the JBL too.
