Whether it's all about the bass or you like a little treble, the Hot Octopuss Kurve g-spot vibrator will have you making beautiful music.
The Verdict:


(out of five)
Welcome to the g-spot vibrator that lets you fully customize your pleasure with Treble and Bass Technology. Lots of vibrators are equipped with two motors just like the Hot Octopuss Kurve is - but very few vibrators are equipped with two different motors.
If you've ever held two vibrators at the same time and turned them on, you've probably noticed that they don't feel exactly the same. Every vibrator's vibrations feel different; vibrations can change with motor size, motor power, sex toy material, sex toy thickness, and more. Sometimes vibrations can feel a bit deeper and muscle-pounding - and sometimes they feel a bit more surface-level and leave your skin tingling.
That was the idea behind the Treble and Bass Technology. The Treble motor, at the tip of the Hot Octopuss Kurve, uses a motor specifically designed for "Treble" vibrations - the type of vibrations that leave your skin tingling when you use them. The Bass motor, at the base of the insertable portion, is designed for "Bass" vibrations - deep, rumbly sensations that are perfectly placed at the vaginal entrance when inserted.
By mixing these two vibration types, you can make your own "perfect" sensations with the Hot Octopuss Kurve. In fact, they market it as "unlimited customization" to find the perfect mixture of Treble and Bass to make your own vibrating "song" to orgasm to.

New technology "don't mean a thing" if the vibrator isn't otherwise well-built, and with the Hot Octopuss Kurve, you get a body safe sex toy packed full of the features you want. The vibe boasts a soft-gel tip that's super plushy and broad for full g-spot stroking. The shaft is perfectly curved to snuggle up to the g-spot. The waterproof design offers easy clean-up while the rechargeable battery gives you a full two hours of use - long enough for almost everyone. The entire sex toy is made of silicone and the Treble and Bass motors both have separate controls right on the handle for easy control,
Hot Octopuss has put its Treble and Bass technology into some of its other products - most notably, the Hot Octopuss Jett which takes this g-spot tech and crafts it for penis pleasure. Instead of putting both Treble and Bass into a "single" toy, the Jett includes two bullet vibrators - each with its own Treble or Bass motor. The Kurve is the first Hot Octopuss vibrator that puts them into the same outer shell.
With so many features, I bet you're super curious to see how it holds up - so let's get to it with the Hot Octopuss Kurve review.
How'd You Use It?
First, we have to gush about one of my favorite parts of this vibe: the super squishy tip. I really, really love the feel of the tip. There are very few sex toys on the market that utilize this type of super-plushy, super-squishy feel, but the Hot Octopuss Kurve does.
It's hard to exactly explain how plushy it is. It's like there's virtually nothing inside the tip except gel. You know how those super-squeezy stress toys feel? The tip of the vibrator feels like that for about the first 0.75" of the toy.
via GIPHY
I was worried that this plushy tip would make g-spot stimulation less effective, but it really doesn't. When pressed up against the g-spot (or try it on your thumb if you want to see a demonstration outside the body), the plushy surface "flattens out" - but still retains a rigid contact surface. It isn't hard to reach that fully flattened point, and it doesn't take too much pressure.
Instead of building the vibrator with this flat surface in a rigid design, Hot Octopuss added the squishiness - which allows the "flat" to specifically adjust to whatever your body needs with no pokey edges. If your body needs a bit more squish on the right side than the left or if your g-spot is more right-ward or left-ward leaning, the squishy tip essentially means that the tip of this insertable vibrator has zero pokey bits. Every way you twist it or use it will always equalize with the same, flat surface as the "squish" compresses into a way that perfectly fits your anatomy.
I wish I had the same love for the buttons at the base of the vibe. I have no idea why the buttons on the Kurve are raised quite so much. I haven't felt a vibrator with raised, click-y buttons in (honestly) years.
On one hand, this definitely helps with touch-only navigation and control of the vibrator. I can figure out how to increase the intensity without even looking at the vibe. On the other hand, they stick out a decently noticeable margin from the smooth, silicone plastic and if you catch them at the right angle, they definitely feel scratchy.
It wouldn't necessarily be the end of the world aside from the fact that the edges of those buttons are a bit rough on the hands - especially if you're someone who likes to rock their g-spot vibrator against the g-spot. I have yet to get cut or injured, but I definitely had soreness on my thumb the next day - from the minus button on the Bass motor, it looks like.
It's just generally a bit odd that the buttons are quite so raised. The circular patterned button on both sides of the vibe don't provide that same scratchy feeling, but the + and - buttons definitely do.
Essentially, the way you hold and grip the vibrator - especially when actively pushing it and rocking it into the body - can leave your fingers resting up against these buttons. Depending on where your fingers like to go, this can leave your fingers "brushing up" against these buttons - a lot. The raised structure of the buttons makes sure that doesn't feel exactly pleasant.
![Hot Octopuss Kurve sex toy review]()
(I see that the Hot Octopuss Jett utilizes the same button structure - which is probably where Hot Octopuss took the design from - but the Jett doesn't have the same active-participation design that a g-spot vibrator rocking up against the g-spot would have.)
Once you adjust your grip in order to avoid being scratched by the buttons, the actual g-spot experience is pretty fantastic. Even for my deeper g-spot, I was able to hit it just fine with the design of the Hot Octopuss Kurve. I'm not able to rock it as intensely as I'd like (because of the button issue), but it does a great job of snuggling up against the g-spot and staying there.
The squishy tip actually seems to do a much better job of really hitting all of my g-spot than a lot of my rigid-tipped dildos have done in the past. It feels more encompassing than narrowly targeted like with a partner's fingers.
I will note that I would have loved another inch or so on the length. The current 5" insertable length means that the top buttons and my fingers are usually covered in bodily fluids when I'm done - which can make the slick plastic base handle even harder to hold. I recommend keeping a towel or something to wipe your hands and the base of the toy. As it stands, I do have to regularly interrupt my thrusting to wipe the handle because slippery fingers make the button issue even more problematic when your hands slip. It's very possible that this is a problem unique to my thicker body, though, with more length "lost" to having squishier labia.
Once the vibrator is in place, the vibrations feel pretty fantastic. They definitely add something to the experience, and I regularly feel like I can specifically feel each "motor" as they play off one another.
I feel the majority of the vibrations at the entrance of my vagina - and the handle, but it's very possible I just don't recognize the specific "g-spot" tissue where the vibrations are hitting. It definitely adds more pleasure to the experience, though, and even if I start with the vibrator turned off, I usually find myself flipping on the vibrations half-way through - especially when I'm getting closer to orgasm and want a great "push" towards the finish line. It definitely adds - not detracts - and I've definitely had a ton of fun flipping through all the vibration intensities and patterns when I'm trying to draw out my g-spot experience.
I'll hit the strongest one and be done when I don't want to draw out the masturbation experience, but when I'm going for self-exploration, all the different vibration patterns and options are amazing.
The Hot Octopuss Kurve does a great job hitting my g-spot, and the top 3.5" of the vibrator are basically perfection incarnate. I just wish the length was longer and the buttons weren't causing such an issue.
How Else Could It Be Used?
I wouldn't necessarily recommend the Hot Octopuss Kurve as a clitoral vibrator unless you really like softer vibrations and a plushier head. The plushier head honestly feels pretty amazing as a general new sensation to enjoy clitorally, but at the same time, that plushier head seems to reduce some of the vibration intensity coming in from the Hot Octopuss Kurve, so it's a double-edged sword. Plus, the "Bass" motor for the Kurve is near the base of the toy. That works great with g-spot pleasure (when it's pleasuring the vaginal entrance), but it means you're primarily left with the "Treble" motor for tip vibrations for the clitoris. When mixed with the plushiness of the tip, you're getting a lot less vibration than most people generally want with their clitoral vibe.
![Hot Octopuss Kurve sex toy review]()
There are some toys that can definitely flip between g-spot vibrator and clitoral vibrator with ease - like the We-Vibe Rave. I wouldn't say that you get the same clitoral pleasure and g-spot experience with the Kurve, though. It just excels at one thing - the g-spot - and unless you love softer vibrations clitorally (and find most vibes much too intense), I think you'll find the Hot Octopuss Kurve pretty disappointing clitorally.
Since the Hot Octopuss Kurve lacks a flared base, it really shouldn't be used anally. The Hot Octopuss etched-in log on the side of the vibe might also make it much-too-easy to harbor bacteria if switching between anal and vaginal on a regular basis.
Product Details
The Hot Octopuss Kurve's claim-to-fame is its Treble and Bass Technology. Essentially, every vibrator you've ever played with has a distinct motor - and a distinct vibration "feel". All of it depends on the toy's material, the motor size, the motor type, and even the size of the toy itself. It all comes together to make the vibrations feel a certain way - which is how your wand massager likely feels nothing like a bullet vibrator.
Hot Octopuss intentionally played with these ideas with their Treble and Bass technology. The Kurve is equipped with two separate motors (just like the Jett!) - each entirely different from one another. The motor within the base of the shaft is the "Bass" motor - which puts out deep, rumbly vibrations that feel deeper and more muscle-deep.
The motor near the tip is the "Treble" motor - which puts out vibrations that feel lighter and more surface-level than the "Bass". By involving two separate motors with two separate locations, the Kurve's idea is that you can "make your own pleasure vibration modes". Each motor is independently controlled via the buttons at the base (more in "How it Works".)
The Treble motor (towards the tip) is powerful for a surface-level, tingly vibrator. The vibrations are definitely most-powerful about 1" down from the tip (where the motor is actually located), and the squishy part of the tip does soften some of the vibration intensity. It's still a vibration you can definitely feel. As noted in the above section, it's not the type of vibration that's functional for clitoral stimulation but when I use a g-spot vibrator, I'm primarily there for the pressure - less-so for the vibration - so this buzzier vibration works a-okay for g-spot stimulation for me.
The Bass motor (towards the base) has a deeper feel to it, but honestly, not by a lot. I've definitely felt more rumbly, deeper vibrations in other g-spot toys (like the We-Vibe Rave). They are deeper than the Treble motor, though, and pretty powerful. With just the Bass motor turned on, you can feel the vibrations in the tip of the vibrator through the squishy top.
![Hot Octopuss Kurve sex toy review]()
On their own, each one of the motors is powerful - but not impressively so. When put together, the vibrator pretty much comes alive with vibrations that are powerful enough to make the handle vibrate as well. The vibrations stay decidedly in the middle of "buzzy vs rumbly" in the vibration debate, but there's a whole lot of vibrations to it that can be felt throughout the entirety of the toy.
With both motors turned on, the Kurve has a bit of a "knocking" noise to it unless pressure is applied to the shaft. So, before you insert it, it's noticeably louder than most vibrators (though still nowhere near the noise level of the Arcwave Ion as I mentioned in my Arcwave Ion review). This knocking noise only seems to happen with both vibrators turned on - regardless of intensity level - so I wonder if it's something about how the vibrations "meet in the middle" or how the two motors interact with one another. If you're someone who needs a lot of discretion, keep this in mind and don't turn on the motors until the toy is inserted.
Once the toy has some pressure on it, the vibrations quiet down immediately. It's still not whisper-quiet, but it's much quieter than the knocking sounds. It's noticeably easy to hear at the loudest settings on both motors - even while inserted. With a door closed and some music on, you'd likely be able to hide the noise - but only if someone wasn't standing at the door. If they stood at the door, it seems likely they'd be able to hear something "different" than the rattle of air conditioning or a fan. The noise isn't distracting during use at all, and it's more like a louder hum than anything squealing or annoying. It fades into the background fast.
If discretion is super important to you at any particular motor, the Treble motor, on its own, is a bit quieter than the Bass motor. It still isn't as quiet as some of the softer toys out there (like the We-Vibe Nova 2), but it isn't as loud as when both motors are turned on.
The Hot Octpuss Kurve is a pretty traditionally-sized vibrator in all facets. The shaft is thick enough to be noticeable and pleasurable - but still smaller than the average biological penis width at most points in the shaft. The length is deep enough to hit most people's g-spots, but some people will find it requires inserting all the way down to the start of the control panel to hit their g-spot. (I would have taken another inch of length from the Kurve.)

How It Works
The Hot Octopuss Kurve has six buttons on its base for controlling the vibrations. Four buttons control the intensity of the vibrations, one button cycles through the patterns the vibrator is equipped with, and the last button solely focuses as the auto-off button for the entire toy when held down for two seconds.
