Prostate massager by Aneros

Add resource

Experience required for best results

The Eupho Syn is the newest Aneros offering and an "improvement" over the original, or at least a redesign with new materials. Whether or not it is better, is dependent on your perspective. The Eupho Syn is a comfortable, smaller-sized Prostate massager that can be enjoyable for any experience level, but might be anatomically or experience dependent, like many of these type toys. The box and website suggest that the Eupho Syn is geared towards advanced users with strong anal muscles.
Silicone, looks nice, comfortable
Price, patience needed, perineum arm too flexible, dust magnet, may need to be advanced user

extremely useful review


The Aneros Eupho Syn is a stay-in-place prostate massager that is designed to move with your motions and/or muscle contractions to stimulate the prostate, while laying down or having sex (or other activity).

Apart from more intense orgasms, the promise of these toys is to help regular men achieve more intense orgasms, stronger erections and PC/sphincter muscles.

The Aneros (like Nexus, Janus and others) are designed to be worn during masturbation, sex, or during relaxation/meditation sessions, in an attempt to have hands-free pleasure or orgasms. Not all men's prostates are created equal or the same distance from the anus though, so experiences vary widely and it can reportedly take years of "trying" and frustration to reach that first super-O (the equivalent of multi-orgasmic squirting in women you could say). It takes practice to condition your mind and body to reach these levels of pleasure and manipulate the Aneros towards the stated goal and not everyone gets there, including myself. They are still pleasurable and beneficial though, regardless.

Aneros website has a thorough set of directions and an active community with resources to help newbies learn to enjoy their toys and get in touch with their "inner self" so to speak.

The idea is to let your natural (conscious and unconscious) anal/pc contractions alternately draw the toy in and let it slide out repeatedly. This produces some nice gentle stimulation against the prostate, which in turn sends tingles up and down your spine and around your genital area, resulting in an intense release. Some users profess to relax and do nothing, while others say they use alternating contractions between the PC and sphincter muscles to create an escalating tug of war moving the toy back and forth.

They can also be used for Kegels, or to just become aware of your prostate and inner workings. I find they can help tone your PC muscles for better erection control and engorge erections more. What's not to like about that?

Material / Texture

The Eupho Syn is an abs plastic spine covered in a solid silicone layer. The silicone has a sort of sandy matte finish to the touch. This is definitely more drag than the plastic versions, which are very smooth. I immediately noticed the toy feels lighter, more flexible and less dense than other Aneros models. It is slightly squeezable and pliable. Unlike the regular Aneros plastic versions, the perineum arm of the Eupho Syn, is quite flexible. It can be bent to position where you like it. This was a big surprise to me. The other Aneros models are very rigid, and I assumed that was integral to the design. The stimulation disk (perineum arm)is also more rounded and comfortable than the previous versions, which was a minor complaint some people had before. The shape of the disk is better, but not sure if the extra flexibility is a plus, minus or neutral. That seems a matter of personal preference, as some like firm materials and some don't.

There is no odor and should be no taste, but you would have no reason to taste the toy. The silicone is non-porous and phthalates-free.

The toy has a fresh attractive new look, but having silicone means you may not be able to use silicone lubricant. A spot test can tell for sure. I really do like the appearance of the toy in it's black and red color scheme, though it was different texture than expected. I can't say whether it's an improvement over the original or not. I think that opinion would vary from person to person. I think I prefer the plastic of the original version for the weight, slickness and ability to use silicone-based lubes.

The material is food grade, latex-free, non-porous and phthalates-free.
    • Not porous at all

Design / Shape / Size

The shape is the same as the original Eupho. It's the thinnest and longest Aneros model. It's about 1" wide at it's thickest portion and 3/4" at the neck. The size could fit beginners, but Aneros website says that the Eupho (smaller girth) is geared towards more advanced users. Personally, I think the different sizes and shapes are hit or miss for the average person. It takes some experience, plus trial and error to figure out what works best for you. I think the reason they say it's for more advanced users is that your muscles and mind have to be more conditioned to get the most out of the Eupho. In contrast, when using the Aneros Progasm for the first time, it was immediately pleasurable. The size alone made for instant stimulation and erection.

I think it is suitable for travel in a check bag and is small enough to pocket. These can be passed off as medical devices too, if you are ever confronted, since their original intent was to help men with enlarged prostates. The toy is whimsical and futuristic looking.

Here you can see the flexibility of the perineum arm (and the dust attraction too!)

The Eupho is very easy to insert with some water-based lube. It did not require any warm-up at all. I could feel some subtle stimulation on and above my prostate. It was nice, but nothing overwhelming. With the other Aneros toys and prostate massagers I have used, there was definitely more of a presence about them.

I don't usually have the time these days for trying extended sessions with these toys to get the most out of them. Some of them can still provide a more intense orgasm though when used during masturbation or sex. This doesn't seem to be one that will show immediate results. My Helix significantly enhanced my orgasms right away and the Progasm gives all sorts of immediate pleasures upon insertion. Each Aneros version has it's own unique sensations, as do other brands of prostate massagers. You don't really know for sure til you try one, how your body will react. The MGX was uncomfortable for me and not particularly pleasant, but it was also my first.

These type of toys generally take some practice and patience to get the most out of them. I can see where someone more advanced can get more pleasure out of this one than a beginner might. I've heard some of them can have anal orgasms without a toy at all after years of experience. It is definitely the least intimidating of all the Aneros, so beginners might still enjoy it too.

Care and Maintenance

The Eupho is easy to care for and, because it is silicone, it can be sterilized by soaking in a 10% bleach solution, cleaning with toy cleaner or soap and water. It can be stored in the box it came in for safe keeping, but is also perfectly fine being stored in a drawer or pouch. The silicone draws dust easily.

I don't know if you can boil this, because of the plastic handle. I think it would be ok, but you could certainly stick the head portion in a cup or small tub of boiling water and let is soak for a few min. I have done this with my Lelo vibrators, taking care to not get the handles wet with no problems and those have electronics in them. The info page says boilable, for what it's worth.

It's best to go with the recommended water-based lubes, if you don't want to chance ruining your silicone toys by using silicone-based lubes.
    • Easy to clean
    • Easy to store


The packaging is very nice and substantial; kinda luxurious. The is a small instruction booklet included, but you can read more about it on the Aneros wiki or doing a search on your own, in order to get the most out of it.

The box is mostly red with black and white designs. The heavy duty cardboard box opens like a book, where there is a plastic cutout to secure the Eupho. The packaging is perhaps some explanation why these toys cost as much as they do. I have seen some of them in cheap shrink wrapped hanger cards before.

Beyond the packaging, you pay a premium for the Syn version, because it is silicone and "new and improved". I can't compare it directly to the Eupho, because I do not own it, but I have the Helix, SGX and Progasm and I really like the plastic. It is high quality and dense, with some heft to it. The Eupho feels feather light, soft and flexible.

Other than the cardboard strip for each model that goes over the book case, the packaging is discreet. You could slip it into a bookshelf without raising any eyebrows. The slip cover shows images of the toys and all the Aneros come in the same box.

The beautiful box mentions it is for advanced users and lists the benefits
    • Good for storage
    • Recyclable


My experience was just okay compared to most of my other toys. This definitely will take some more experience to get the most pleasure out of it. I found it comfortable and mildly pleasurable, but nothing amazing. At least not yet. I still am trying to master some of my other toys. Some toys will give immediate results and some take more patience. There are a lot of variables as well, like cleanliness, amount/type of lube, weight, material, drag, experience, fit of toy to anatomy etc. None of these toys are one-size fits all. Everyone will experience different models in a unique way most likely.

This is probably not the right toy for instant gratification or immediate results, nor does it promise such. I will definitely revisit as I get more and more experienced. If you prefer plastic, firmness and slick surfaces, consider the original model.
Follow-up commentary
This toy never did it for me from day 1. I prefer the plastic smoothness to the silicone. I also never liked that the perineum arm is flexible. The size also didn't do much stimulation for me. I think the regular version would have been better. I can't recommend this one. I got rid of it.

    As usual, I deeply appreciate your comparisons and expertise. Sorry to hear it wasn't a great experience but I agree these are literally "hit or miss" in most cases. I wish I had more time to become experienced and enjoy the subtlety of some of these more.
