Product description
This Mjolnir Bluetooth speaker puts Marvel's Thor's Hammer on your desk: a replica hammer with a real speaker in the head, and a swing that answers with thunder.

A real speaker in the head
Two drivers share 8 W inside the hammer head, fed over Bluetooth 5.3 with a range of around 15 metres. A 1000 mAh battery gives four to five hours of music and recharges in about three.

Swing it
A gyroscope reads the motion. Swing the hammer and it answers with a strike, or with thunder — effects that run on their own, whether or not anything is paired.

The cradle is the charger
Set the hammer down in its rock-effect base and the magnetic contacts line up on their own. On display it is always charging; off the base, the lanyard and the magnetic head take it to the gym, the car or the locker.

Swing it for thunder
My kids take turns swinging it just to hear the thunder crack. It works even with nothing paired.

Sticks to the fridge
The magnetic head holds it on the fridge door while I cook, playing podcasts. Did not expect to use it that way.

Cradle is the charger
No cable to fiddle with. Drop it in the rock base, the contacts snap together and it charges while on display.

Better sound than I thought
Two drivers in the head fill my garage workshop. Not a party system, but clear and loud enough.

Gym locker companion
Clamps to the inside of my locker door and the lanyard makes it easy to carry to the rack.

Frequently asked questions
What is in the box?
The hammer, the rock-effect charging base, a USB cable, a wrist lanyard and the manual.
How big is it?
The hammer is 95 × 55 × 183 mm, and 165 × 106 × 190 mm standing in its cradle.
Is it waterproof?
No. Keep it dry; take it to the gym or car on the lanyard or stuck to a steel surface by its magnetic head.
How do I pair it?
Turn it on, open Bluetooth on your phone or tablet and choose "KBMVH". It uses Bluetooth 5.3 and reaches about 15 metres.
What do the swing effects do?
The gyroscope detects a swing and plays either a strike or a thunder effect. The effects work on their own and do not interrupt the pairing.
How do I charge it?
Set it in the base — the magnetic contacts find each other — and it charges fully in about three hours. The base doubles as the display stand.
Can I take it out?
Yes. It comes with a wrist lanyard, and the magnetic head holds it to a car panel, a locker or any steel surface. It is not waterproof.
