Stylophone Mini: the pocket synth that clips onto your keys
The Stylophone Mini is played with a stylus on a tiny nickel-plated keyboard, and clips onto your keys or a bag. Speaker, vibrato and white LED are built in.

What it is
The Stylophone Mini is a synthesiser you play on your keyring. Like its bigger sibling, it works with a stylus that you touch to a small metal keyboard. Each contact produces a note, and the sound comes straight from the device through a built-in speaker.
What sets it apart is its size. It clips onto your keys or a bag. So it goes wherever your keys go: in a jacket pocket, at the bottom of a rucksack, hanging from the strap of a satchel. The stylus is attached to the device, so you always have it with you.
It is for people who like unusual musical objects, for the curious who want to discover how a Stylophone works, or for anyone looking for a gift that gets noticed. It comes in three colours: Original, Pink and White.
Why it exists
Stylophone is the pocket synthesiser brand of Dubreq Stylophone. Its signature product is a synthesiser played by touching a metal keyboard with a stylus. That simple, immediate gesture is the whole identity of the house.
With the Mini, the brand takes the pocket idea one step further. It presents it as an even more compact version of its “iconic pocket synth”. The aim is clear: shrink the instrument to the size of a keyring without giving up the ability to play it.
What matters
The keyring format. The Stylophone Mini measures 10.4 cm long, 7.9 cm wide and 2.3 cm high. It is an object that fits in your hand. At 2.3 cm thick, it stays flat and slips easily into a pocket or a bag compartment.
The nickel-plated keyboard. The keyboard is miniature and nickel-plated. It is what makes a Stylophone a Stylophone: the stylus touches its metal keys to trigger the notes. You play by sliding or tapping the tip from one key to the next, with a single finger.
The attached stylus. The stylus is built in and attached to the device. On an object that spends its life on a keyring, that detail matters: the tool you play with does not wander off on its own.
The built-in speaker. The sound comes straight from the device. The Mini is played as it is, with no headphones or speaker needed.
The vibrato button. The Mini has a vibrato effect button. Vibrato makes the pitch of the note waver slightly. It is one of only two controls on the device, along with the on/off switch.
The white LED. A white LED is built into the device. It adds a touch of light to an object you are happy to pull out and show off.
Day to day
Getting started comes down to two controls: an on/off switch and the vibrato button. You switch on, pick up the stylus and play. The clip lets you attach it to your keys or a bag, then detach it when the urge to play strikes.
The device runs on two LR44 button cells, supplied in the box. An automatic switch-off is included. It saves the batteries if you forget to turn the device off before putting it back in your pocket, which is easily done with an object that lives among your keys.
The Mini is made of metal and plastic. It comes in a Stylophone metal tin, which holds the device and its attached stylus. The tin can be used to store it when it is not on your keyring.

What the brand says
Stylophone presents the Mini as an even more compact version of its “iconic pocket synth”. The brand thus places this model in the lineage of its signature instrument, with size as the selling point.
According to Stylophone, it is a fully playable Stylophone, always ready to use. The promise is about the essentials: despite its keyring size, the Mini is meant to remain a real instrument, not just a decorative gadget.
The brand also states that the Mini is self-sufficient. According to it, nothing beyond the device and its stylus is needed to start playing.
Why it caught our eye
We spotted it for its very simple idea: a real Stylophone, with a nickel-plated keyboard, attached stylus and speaker, at the end of a keyring. We also like the vibrato button and the Stylophone metal tin, two details that give character to such a small object.
Exactly the kind of brand we’d love to come across on O!deal one day.
