Zumio I Review + Comparison: Zumio X vs. S. vs. E. vs. I oscillators
Broad wand vibrators can be held against a cheek for next-level blowjobs. Firm, pinpoint oscillators can be held between the tongue and clit for next-level cunnilingus. Try that with any of the Zumios; you’re welcome.
Here’s why I love the Zumio lineup — and why the new Zumio I is the best yet. Nerd alert: this Zumio review and comparison will get granular and technical.

What is a Zumio vibrator/oscillator?
Zumio oscillators are among the sharpest, most pinpointed clitoral stimulators currently on the market, with little stems and heads that oscillate in circles. They’re for the schlicker who likes using a fingernail over the hood and appreciates precision when reaching orgasm. Zumios are essentially “instant orgasm” buttons for me.
They’re itty-bitty, and because of that, they carry a high concentration of intensity. If a wand were a wrecking ball, the Zumio massagers would be laser cutters — their precision makes them effective in an entirely different way.
With wands, it can feel like an all-or-nothing where I either insta-cum or get insta-numb (especially if I was on a higher dose of SSRI or just not in the mood). And then the latter situation takes me forever.
In contrast, my orgasms with the Zumio I immediately ramp up, regardless of medication. Pinpoint oscillators just make orgasms way faster and are more reliable for me. Your mileage may vary, but if you relish focused vibrations, it’s hard to top the Zumio vibrators.
Zumio X measurements and specs
When the Zumio X was first released, its combination of rumble and size was unprecedented. Bullet vibrators often weren’t as sharp or powerful, nor were their circular movements as distinct as the Zumios’.
Here’s how the Zumio X physically measures up:
- Total length: 18 cm (about 7”)
- Head maximum diameter: 5.5 mm
- Stem minimum diameter: 2.9 mm
- Tip length: 32 mm
- Handle maximum diameter: 3 cm (about 1.2”)
However, the Zumio X’s uniqueness, specialization, and compact nature didn’t make it above reproach. Its size conjures associations with motorized wiggle pens and electric toothbrushes.
Also, looking past the superficial, many users found it too emphatic; I rarely went past the third speed setting out of 8. (Good thing Zumio’s 3‑button control panels make it easy to increase and decrease intensity!)
Zumio S vs. Zumio E vs. Zumio I
In the following years, the Zumio S, E, and I were released to satisfy a broader range of users. While the newer Zumios’ handles are the same shape and size, their tips and motors vary.
Zumio tip shape and size comparison
To summarize how the other Zumio tips compare to the Zumio X:
- Zumio S - softer with a shorter stem to limit the movement radius and a broader silicone-coated tip. Feels waaaay gentler.
- Zumio E - thinner, metal, paddle-shaped tip with elliptical movements. Play with different degrees of sharpness along the sharp edge or flat face.
- Zumio I — also paddle-shaped but a bit chunkier. An excellent hybrid, less like a fingernail than the Zumio E and more like a flattened bead.
Zumio frequency and vibration quality
The differences stated above led to this question from an Instagram follower: are the tips the only variable? If so, why wouldn’t they just make different attachments to put on one base?
The short answer is that the motors are very different between the original Zumio X and the newest Zumio I — their lowest speeds are 146 Hz and 105 Hz, respectively. That’s a whopping 28% difference. Here are the other Zumios’ oscillation speeds, at a glance:
- Zumio X — 146 to 179 Hz
- Zumio S — 135 to 164 Hz
- Zumio E — 129 to 155 Hz
- Zumio I — 105 to 161 Hz
These speeds are certainly high frequency, but because the tips revolve in bigger circles than a conventional vibrator, it’s still super strong and registers to me as rumbly.
Do Zumios slow down under pressure?
Yes, they definitely dampen with pressure. Zumios are made for light touch, which could be good or bad for you. On the one hand, plenty of users want to push their clitoral vibrators hard.
On the other, your clit might be sensitive with a Zumio right after orgasm, so adjusting the pressure and positioning to make it gentler can be an asset. Use the stem for a more diffuse sensation, or move the tip higher up, where the feeling is way less direct.
What does this all mean for how Zumio feels in use?
Let’s compare my experiences with the Zumio variants, from favorite to least favorite.
Zumio I (Iyana)
Best for a slow build and multiple orgasms
The Zumio I delivers a lot of what I like about the Eroscillator + Golden Spoon combo in a more compact carrier. Its speed range can feel beautifully subtle or strikingly severe. While its tip doesn’t immediately feel sharp or punchy, the orgasms hella sneak up on me. If I’m not holding back, the Zumio I could hypothetically make me squirt.
It’s also more versatile than the other Zumios, and the sensations feel deeper and way more satisfying. The Zumio I’s broad paddle head allows for quite a few different sensations:
- Something more pinpoint when the long edge is pressed against me
- Tapping motions with the broad face
You get a little bit of everything that makes the other Zumios great. There’s nothing I dislike about the Zumio I; it’s perfect for a pinpoint princess.
And, compared to the Eroscillator, this Zumio is:
- Way more compact and travel-friendly
- Rechargeable instead of having a cumbersome cord
- Easier to navigate with a bigger speed range
- Slightly less ugly (still looks like an electric toothbrush base, though!)
If I had to get just one oscillating vibrator, it would be the Zumio I.
Zumio E (Ethel)
Best for intensity
The Zumio E’s tip is suuuper thin like a fingernail for the sharpest sensation when you use the edge. I can even dig through the prepuce, under and behind the glans. That’s how precise it is.
I loooove that feeling over my clitoral hood, and it closely matches how I touch myself manually. While the Zumio I is a fantastic all-arounder, the Zumio E is the specialist.
Even if you don’t want the slightly piercing sensation at all times, you can use the flat face to (literally) take the edge off. It's still pointier than the Zumio X. However, as with the Zumio S, there are lower and slower speed settings.
If you like using fingernails when masturbating, you’ll love the Zumio E.
Zumio X (Xena)
Best for quickie orgasms
The Zumio X starts at the highest frequency and is super strong right away; there’s no subtlety with it. I usually won’t even go past the Zumio X’s second setting, let alone use half of the speed range.
Orgasms with the Zumio X are suuuuper fast and feel very “one and done” compared to the others. I cum more quickly and get sensitive afterward, but I don’t stay satisfied for as long as with the other Zumio models.
The Zumio X is a lot, and not everyone can handle it. Can you?
Zumio S (Sadie)
Best for softer centering
At the time of the Zumio S model’s release, I appreciated its coyer nature. Nowadays, I’m “meh” about it. It still has power but loses its distinctiveness, and at that point, I’d rather spend a little extra and use the Eroscillator.
In short, think of the S model as the “lite” Zumio. It’s for the user who wants:
- A gentle-to-moderate strength vibrator
- Great steady settings and controls
- Something lightweight that doesn’t take up too much space
Everything else you need to know about Zumios
There are a couple of glaring downsides, one of which Zumio has addressed in recent years!
First, the Zumio tips’ slender stems aren’t exactly exemplary of stability. Past users were concerned about them getting crushed and snapping when sloshed around in a bag with bigger, heavier items. Nowadays, all Zumios come with carrying caps to protect the heads!
The other thing: Zumios’ charge time is ass. You’ll likely want to leave your Zumio connected overnight — 12 hours of charging gets you 4 hours of playtime. If it dies, it’s not a toy where you can plug it in, quickly shower, and come back and get off. I’m willing to overlook that in the long run, though.
Closing thoughts on the Zumio
The Zumio lineup has come a long way — from quick orgasms with the Zumio X to comfortable caresses with the Zumio S to sharp sensations with the Zumio E.
Best of all is the Zumio I, which offers a little bit of everything:
- A wider range of speed settings than before
- A versatile head for many different kinds of stimulation
- A slow(er) burn that leaves me feeling more satisfied
And in my world, that last point is quite a feat for such a small massager. Not only are Zumios unique and in a class all their own, but the Zumio I is currently my favorite compact oscillator. Use it for 3 minutes or 3 hours — it’s a delight every step of the way.
Do you prefer fingernails on the clitoral glans or a palm against the whole vulva? If you answered the former, I only have good things to say about the Zumio I.
Where to get 10% off a Zumio
Take 10% off your whole order when you use code SUPER at Betty's Toy Box.
Thanks for the comparsion between them all! Definetely getting the E version when(or if…) they're available here in my country lol. It sounds like a perfect balance.
For now tho i am torn between the X and S — i never masturbated with a fingernail (more like.. 2 fingers on the clit and a pretty little amplitude.. with a lot of force) and i kinda have a feeling that X might be too sharp, and S sounds like it can be a lack of power. May i ask for your advice here?
Overall, i am totally a fan of pinpoint(ish?) vibes and most of them i use on highest setting avaliable (Tango X and the Volta that i got mainly because of you, hehe)
If you're in doubt, I'd say to go with the S
