The Aneros Eupho Syn V is a slim, hands-free vibrating prostate massager built around the mobile Eupho profile. It can be used with vibration or unpowered, so the same curved shape supports two distinct styles of play. The device offers 10 vibration patterns, four motor-speed selections, onboard control, and a wireless remote. Its official insertable length is 4 inches, while its narrow head measures 0.85 inch wide and 0.92 inch deep.
This is the powered Eupho Syn V, not the manual Eupho Syn. The live Stag Standard product is SKU 94943 and is sold as one simple product rather than a size or color variation. Before opening, compare the name and SKU with the package, inspect the seal and box condition, and keep all supplied instructions and charging pieces together.

The current official Aneros page does not publish total length, product weight, motor noise, wireless range, charge duration, battery runtime, ingress-protection rating, charger connector, or a complete box-contents list. This page does not estimate those details. The received package and current manufacturer instructions control if they differ from this summary.
Who this shape may suit
The Eupho profile is deliberately slim and mobile rather than large or heavily anchored. Its narrow head and subtle curves are intended to respond to pelvic-floor contractions and changes in body position. That responsiveness may appeal to someone who already understands how a hands-free prostate massager moves, but size alone does not determine whether a model is beginner-friendly. Comfort, anatomy, relaxation, lubricant, positioning, and familiarity with anal insertion all matter.
If you are comparing your first prostate toy, begin with how to choose a prostate toy and how to use a prostate massager. The guide to butt plugs versus prostate massagers explains why a prostate-focused curve and an external base behave differently from a plug intended mainly for steady fullness. You can compare additional shapes in Prostate Toys.
Understanding the measurements
The 4-inch figure is insertable length, not the device’s total end-to-end length. Head width and depth describe different axes, so the head is not a perfect circle. The mid-ridge dimensions likewise describe the widest points published for that section, not a promise that every user will experience the same pressure or contact.
Do not compare only the largest number with another toy. A gradual taper, stem flexibility, curve, external tabs, surface drag, and movement can change how a device feels. If 4 inches is beyond your current comfortable depth, choose a smaller or simpler product instead of planning to force partial insertion while the external arms sit incorrectly.
Charge, inspect, and test before use
Read the received instructions before charging. Use only the supplied or manufacturer-approved charging arrangement, keep charging contacts and connectors dry, and disconnect the device after it is fully charged. Aneros advises that leaving an electronic model connected after it is full may reduce battery life. Do not charge on bedding, under clothing, beside a sink, or anywhere heat or moisture can collect.
Before every session, inspect the insertable surface, seams, stem, external arms, button, charging area, and remote. Do not use the device if the surface is torn, swollen, sticky, deeply scratched, separating, or permanently discolored; if a control is loose; if the charging area is corroded or wet; or if the unit becomes unusually hot, smells burnt, will not hold power, or behaves unpredictably.
Test the controls before insertion. The official quick-start sequence says to double-click the device multifunction button to turn it on. A blinking indicator means ready mode; single-clicking advances through patterns 1 through 10. Holding the device button for two seconds changes speed. Learn how to return to a lower setting and power off while the product is still in your hand.
Pairing and using the remote
The Eupho Syn V must be turned on manually before the remote can connect. Hold the remote multifunction button for two seconds to power the remote on. The display begins in ready mode at 00. Use the left and right arrows to move among the 10 patterns, and single-click the remote multifunction button to select one of the four speeds. Holding the remote button for two seconds afterward turns both the remote and device off.
Confirm that the remote responds at close range before insertion. Wireless performance can change with distance, barriers, battery level, and body position, and the manufacturer does not publish a guaranteed range on the current product page. Keep the onboard button reachable and do not rely on the remote as the only way to stop. For partnered use, decide who controls the remote, agree on stop words or signals, and return control immediately when asked. The Stag Standard guide to using sex toys with a partner covers consent and control-sharing.
Lubricant and preparation
Aneros classifies its flexible massagers as silicone and directs users to water-based or plant-oil-based lubricant while warning against silicone- and petroleum-based lubricant. A plain water-based formula is the simplest starting point for most people because it is easy to reapply and rinse. Review how to choose a water-based lubricant before combining products.
Wash the device before first use, empty your bladder if that is more comfortable, and give yourself time to relax. Apply lubricant generously to the insertable portion and the anal opening. Add more if friction develops. Do not use a numbing product to mask discomfort: pain, burning, or sharp pressure is information to stop, not a sensation to cover.
Insertion and hands-free use
Begin with the motor off. Lie on your side or choose another stable position where you can reach the device and stop easily. Guide the head in slowly without pushing on the external arms. Allow the body to accept the curve gradually until the external perineum tab rests outside the body as designed. Never force the stem or insert the external arms.
Pause after insertion. Breathe, release tension, and confirm there is no sharp pain, burning, pinching, bleeding, numbness, dizziness, or pressure that feels wrong. The device is intended to move with controlled pelvic-floor contractions; it is not a lever and should not be driven inward by its external base. If it will not settle comfortably, remove it, add lubricant, change position, or stop the session.
When you are comfortable, start at the lowest speed and a predictable pattern. Increase one variable at a time so you can distinguish speed from rhythm. The published speeds are 10%, 20%, 40%, and 100%, but those percentages describe motor selections, not guaranteed perceived intensity. You can also leave the motor off and use the shape unpowered.
Stop immediately for pain, bleeding, sudden numbness, unusual swelling, persistent cramping, dizziness, loss of control of the device, or any sign of surface damage or overheating. Do not use while asleep, heavily intoxicated, sedated, or unable to monitor sensation and remove the product. Do not share an insertable device without an appropriate barrier and complete cleaning between users.
Cleaning the electronic model
Turn the device off and disconnect it from charging before cleaning. Aneros directs users to wash before and after use with non-abrasive soap and water, rinse away residue, and allow the surface to air-dry. The supplier describes this model as splashproof rather than submersible, and Aneros advises avoiding long immersion for electronic models. Do not soak it, leave it under running water longer than needed, or place it in a dishwasher.
Do not boil the device or use bleach, acetone, petroleum solvents, abrasive powder, or a cleaner that is not compatible with silicone and electronics. Wipe the remote according to its received instructions and keep its openings dry. Review materials and care and how to clean and store sex toys for general handling principles, while treating the Aneros directions as controlling for this model.
Drying, charging, and storage
Air-dry every surface completely before reconnecting the charger or placing the device in storage. Pay attention to the button, charging area, stem junction, and the spaces around the external tabs. Store the device and remote clean, dry, and separated from sharp objects, direct sun, high heat, and materials that may transfer dye or damage the surface.
For travel, power the device off, protect the button from accidental activation, keep the charger with the correct product, and follow carrier and destination rules for rechargeable batteries. The guide to traveling with sex toys covers batteries, privacy, and packing. Do not leave the product in a hot vehicle or checked bag when battery rules require carry-on handling.
Warranty, returns, and order support
Aneros states that its vibrating electrical products have a two-year manufacturer warranty from the purchase date and that its massagers are covered by a 60-day product-performance guarantee. Eligibility, proof of purchase, registration, exclusions, and the available remedy are controlled by Aneros’s current terms; this retail page does not expand or replace them. Keep the receipt, package, model information, and charging accessories.
Before opening a hygiene seal, confirm that the package identifies the Eupho Syn V and that the box is not crushed, wet, opened, or missing expected components. If the item appears wrong or damaged, do not charge, wash, insert, or test it. Review returns, refunds, and hygiene first so you do not unintentionally affect eligibility.
