About this item

  • KEEPS YOUR POCKET OPERATOR PO-133 SAFE - The teenage engineering CA-X Red is a tailor-made silicone case that protects your Pocket Operator Street Fighter from accidental bumps or scratches.
  • PREVENTS THE POCKET OPERATOR FROM SLIPPING OR SLIDING - The anti-slip feet keep your PO-133 Street Fighter in place, on top of a desk or keyboard.
  • OFFERS BATTERY-PROTECTION - To ensure the batteries won't fall out during practice or live performances, the CA-X Protective Case keeps everything in your Pocket Operator in place.
  • DOES NOT OBSCURE THE MIC OR SPEAKER - The CA-X Red Case has specific cutouts for the microphone and speaker for you to hear the beats clearly. Plus, this silicone casing doesn't completely hide the LEDs on the Pocket Operator.
  • OFFERS A UNIVERSAL FIT FOR ALL POCKET OPERATORS - Instead of specific symbols, the CA-X Case features numbers so that you can use it with any Pocket Operator. It is compatible with PO-12 Rhythm, PO-14 Sub, PO-16 Factory, PO-20 Arcade, PO-24 Office, PO-28 Robot, PO-32 Tonic, PO-33 K.O!, PO-35 Speak, PO-128 Mega Man, and PO-137 Rick & Morty.

Favorite Pocket Operator Case
The Teenage Engineering Silicone Pro-Case is a must-have for any Pocket Operator, and it’s especially perfect for my PO-128 Mega Man edition. First off, the fit is spot-on—it snaps snugly onto the Pocket Operator and instantly makes it feel more solid and professional. (Just snap the tag. I know it hurts but do it.) Without the case, the Pocket Operator can feel a bit fragile, but the official case eliminates that worry entirely. It makes it feel like a finished product. What really impressed me is how much it improves the overall experience. The silicone adds just the right amount of grip and weight, so it doesn’t slip out of my hands during a jam session. Plus, the button overlays are a game-changer (pun intended). They make it easier to hit the controls precisely without accidentally pressing the wrong one—a big deal when you’re juggling beats and effects on the fly. This case doesn’t mess with the aesthetic. In fact, the muted silicone actually complements the design, giving it a sleeker and more polished look. It even makes the Pocket Operator feel more like an instrument and less like a calculator from the ‘80s (though I love that retro vibe). I've tried other cases like the acrylic one (which looks beautiful and really displays the PO's PCB design, but the plastic buttons just don't feel as responsive.) Also this case doesn't sacrifice the portability. Pro Tip: If you’re like me and you love taking your Pocket Operator on the go, this case is a lifesaver. It adds enough durability to toss it into a bag without worrying about bending the board or scratching the screen. Final thoughts: It’s hard to believe such a small upgrade could make such a big difference, but this case is worth every penny. Whether you’re a Mega Man fan or just want to protect and enhance your Pocket Operator, this case is essential.

    This is a great case for the TE-PO33 or any other Pocket Operator. I have the PO-33 and it was very easy to install into the case. It fits perfect and I love the included lanyard. Now I feel like my PO33 isn't "nekkid" lol. It looks very well made and like it will last for a long time to come. The function buttons are labeled perfectly so you can easily look at them and recall exactly what each one does. Also, you can see the LEDs for the pad buttons just fine while it's inside the case. I would HIGHLY recommend this case for any PO owner and I think you will not be disappointed!

    It's a bit of a pain to get on properly and doesn't really fit snugly, but the case works for what it needs to well enough. There's a bit of a weirdness where you have to snap off the hang tag from the Pocket Operator, but after getting over the dissonant moment, my kid was eager to use her pocket operator.

    Pretty crazy little device. Kudos to the engineers who came up with the idea. I probably won’t use it for any serious production, but it was worth the purchase. I made one beat with it so far. Wont be doing that again, but to be honest, it was worth buying it just for that one beat, lol.
