Lovense DIAMO Review: The Best Bluetooth Cock Ring?

By M.Christian

The Max 2 is for people into stroker-type toys. The newly-released Lush 3 is ideal for pleasuring a clit, while doing the same for the G-spot. The Edge 2 also does double-duty, though this time it’s to excite the prostate and the genitals.

If you prefer only anal stimulation, there’s the Hush. Meanwhile, if you’re fond of classic wand vibrators, look no further than the Domi 2, Osci 2, or Mission.

With all these fine toys, it certainly looks like Lovense’s got one for practically every kind of genitalia or form of sexual enjoyment.

Except, that is, for folks into penile constriction toys – which I’d be saying if they hadn’t just released the Diamo: Lovense’s first-ever vibrating cock ring.

A toy I’m now going to explore for you, including its various features, how it works, using it, setting it up, and then my opinion on if it’s worthy of spending your hard-earned bucks on.


What the Diamo’s All About

Though it’s Lovense’s first foray into cock ring toys, it’s obvious they dedicated a considerable amount of time, and copious amounts of research, into getting it right.

Case in point, the Diamo isn’t a run-of-the-mill cock ring that happens to have a vibrator attached to it. Instead, Lovense made it a vital component of the toy’s overall design.

So, while the ring constricting the penis vibrates, the majority of it goes to that sadly often-overlooked region between the anus and the base of the penis: the perineum.

Overlooked by sex toys, I mean, as anyone who enjoys sexual activities with the penis-equipped population is no doubt intimately (and then some) familiar with how arousing the perineum can be.

Then there’s the ring part I mentioned. That’s for slightly reducing the blood flow from the base of the penis, up the shaft and to the head (the glans) – which can feel really, really, great.

What’s so Great About a Cock Ring, Anyway?

Slipped over the head and down the shaft of a penis, and from there positioned behind the testicles, cock rings do their magic by, as I said above, somewhat diminishing blood flow to the shaft and the head of the penis.

Emphasis on slightly and somewhat as if too tight, or worn too long, cock rings have been known to cause permanent damage to this remarkably fragile part of the human body… for those that have them, of course.

Cock rings come in all kinds of shapes, styles, and materials ranging from steel rings (not recommended for anyone save the experienced), latex, Velcro, jelly-like plastics, and leather (with or without snaps).

Regarding what they do and why they remain so popular among the penis-equipped links back to how their constriction reduces sensitivity, prolongs an erection, delays orgasm, and allows for better control – to name only a few fun facts about them.

So considering how long-established cock rings are in the world of sex toys, it’s not surprising that Lovense would one day try their hands at manufacturing one with their usual world-class attention to detail.

That’s also good news for those of us who count themselves as fans. The Diamo clearly demonstrates that Lovense didn’t just make yet another cock ring but instead designed one that does what many of them haven’t been able to do before.

What Makes the Diamo so Interesting

Though I touched on how it vibrates the perineum, as well as the function of its ring part, I want to add a few more details as to why the Diamo is so important, interesting, and exciting.

As a person with this set of genitals, it can be frustrating to see so many sex tech companies follow the tired old design idea that it’s the penis and nothing but the penis when it comes to stimulation.  The reality is that – depending on differences in biology and what does or doesn’t arouse someone – there’s a whole lot more to pleasuring male genitalia than merely stimulating the sausage in sausage-and-two-eggs.

Including how pleasurable stimulating the area around the anus, the base of the testicles, or the nerves above and to the side of the genitals can be.

Again, Lovense didn’t have to give us a toy with the potential to pleasure these areas, but they did – and a hearty thanks to them for doing it.

In addition to stimulating the perineum, the Diamo delivers pleasant vibrations to whoever else is involved during penetrative sex – though how much depends on what kind of positions are used, what their genitals are, and how they like them pleasured.

Though I’ve praised the Diamo for perineum-play, that’s not the only way to use it. On its product page, Lovense has suggestions for how best to use the Diamo, like placing the vibrating unit above and back against the wearer’s body to add tension, forward to vibrate against the shaft, below but forward to vibrate against the testicles – and whatever else people can dream up.

Another unique thing about the Diamo is its asymmetrical design, which might make it somewhat awkward to use, depending on if the wearer is right or left-handed.


Looking at it from the wearer’s perspective, with its vibrator under and curving back, the single-button control is on the left, above the Diamo’s status-indicating LED light – and below that the toy’s metallic magnetic charging connection points.

A one-button-does-all design is not all that common with Lovense products, but like those that do have one, the Diamo’s does everything you need it to, beginning with powering the Diamo on or off – if you hold it down for three seconds – or by tapping it, cycling through the Diamo’s ten preset patterns and three levels of intensity.

I promise I’m not going to, yet again, bring up my issue with magnetic charging systems. Mainly because I know you’re probably getting tired of me ranting about how frustrating they can be, though mostly with the Diamo Lovense has shown they actually know how to make one that works.

Regarding its all-important charge-to-playtime ratio, the Diamo is superb: clocking in at a very respectable two hours of effective use for an hour and ten minutes of charging.

Similar to other Lovense toys, the Diamo is sheathed in body-neutral silicone that’s rated IPX7 for waterproofness, so you can shower or soak in your bathtub without worry.

On that, its silicone skin should only be exposed to clear water. So keep it away from the ocean or hot tubs as there’s nothing worse than a corroded sextoy.

Cleaning the Diamo needs just a small amount of gentle dishwashing soap and warm, though not hot water – as high temperatures will also damage the silicone.

The Diamo weighs three ounces (86 grams), with a total length of 5.3 inches, 2.75 of which is the vibrating part.

However, the inner diameter of the ring is 1.7 inches – a critical point I’ll be addressing in my verdict below.

Unboxing the Diamo and Setting it Up

If you’ve gotten your hands on any of Lovense’s products, you know the drill regarding what they come up with – not counting the toy itself.

The Diamo is no different, with customers receiving a charging cable (USB, without a power supply – but no sextoy company includes one), a quick set-up guide, an in-depth manual, and a stylish bag to put your Diamo in when you aren’t using it. The Diamo also comes with Lovense’s standard one-year warranty.

As I touched on – right up there with how well-thought-of they are for the quality of their products – the Diamo is as brainy as every toy they sell.

To get this going, download the Lovense Remote app to your computer (PC or Apple) or smartphone (Android or iOS) and put your newly purchased Diamo into Bluetooth standby mode.

Once connected, the Lovense Remote can be used to operate the Diamo, and with far better options than those provided by its single hardwired button.

For example, you can create customized intensities or patterns, and share what you’ve made with other users – or see what they’ve come up with, as well.

There’s also the option to set the app to do its vibrating thing to ambient noises (oooh ahhhh), make the Diamo dance to your hottest tunes, or – with the Lovense Remote’s built-in video chat feature – put a face to the person you’ve allowed to take control of the toy, making it ideal for all kinds of limited-only-by-your-imagination teledildonic pleasures.


  • Lovense’s first cock ring toy.
  • Options to stimulate the entire genital area.
  • 175 Minutes of playtime with a full charge.
  • Waterproof for shower or tub enjoyment.


  • May not be pleasurable for those unfamiliar with cock rings.
  • Suitable only for those who like penile constriction, along with perineum stimulation.

Lovense Diamo Review: The Verdict

Though I have a reasonably substantial amount of experience with this new – and fascinating – generation of sex toys, it’s quite cool to be able to share my thoughts on Lovense’s Diamo through the lens of someone with (gasp) thirty+ years of cock ring use.

This is why the Diamo is such a kick to write about, as far too frequently otherwise intelligent sex tech companies have tried to upgrade this classic sextoy only to make me feel they didn’t get it – as in what makes cock rings so enjoyable.

Or, for that matter, how for all of their good points – and believe me, there are plenty of those – cock rings have one inherent… well, maybe not a flaw, per se, but something that can make shopping for one quite challenging.

It goes like this: even the most stretchy of stretchy rings doesn’t mean it’ll be a perfect fit. The reality is how comfortable or effective a ring is or isn’t is not simply a matter of size but material, ease of getting it on or off (particularly in a hurry), whether or not someone’s pubic region is closely trimmed or a nearly impenetrable thicket of pubic hair … and on and on and on.

So, like many cock ring fans, I have a drawer full of them – and several dozens more I tossed away because they looked good when shopping but never felt right when worn.

So, blindly buying a cock ring or without the ability to take it for a ride can be problematic. Plus, there’s not knowing if it’ll be too tight or too loose, will pull the right (or wrong) way, and so forth.

That Lovense lists the inner diameter of the Diamo’s ring is a fantastic start as it grants potential purchasers at least somewhat of an idea of how effective/comfortable/tight it might be.

Summing up, and thank you for indulging my thoughts on this, Lovense makes some of the finest sex toys on the market – and because of that, I can unequivocally say the Diamo is fantastic and well worth the price.

However, unless you know your way around a cock ring – especially after developing the ability to understand what a silicone one with an inner diameter of 1.7 inches means for how enjoyable it could be – I would approach this purchase a little cautiously.

If you’re new to cock rings, my advice is to hold off on buying a Diamo until you get yourself an assorted pack of materials, sizes, shapes, and styles to familiarize yourself with what a cock ring actually feels like to you.

Even after that, there remains the possibility that for this or that reason, the Diamo won’t work for you – and you’ll have spent a not-small-amount of money for a toy that’ll end up gathering dust in a closet somewhere.

If you can accept all this and are experienced enough with cock rings – or have the disposable income to roll the dice – then, most definitely, I have no qualms about saying that you should pick up a Lovense Diamo.

Otherwise, have fun playing with all sorts of cock rings and – when you feel you have a good grasp of what you like and can afford it, too – get yourself a Diamo, as well.

Because the Diamo is from Lovense – and you can’t get any better than that!
