The Screaming O Wow Double Wammy delivers simultaneous dual-motor vibration powered by replaceable batteries, making it the most direct choice for targeted clitoral and shaft stimulation. The Colorpop Big O 2 adds multi-speed patterns, while the Charged Big OMG provides USB-rechargeable power with a single vertical motor. Choose based on charging preference and motor placement.
Key takeaways
- Motor configuration defines sensation. The O Wow Double Wammy and Colorpop Big O 2 use two motors for simultaneous clitoral and perineal stimulation, whereas the Charged Big OMG uses a single vertical motor engineered for direct clitoral alignment.
- Power source splits battery vs rechargeable. The Double Wammy and Big O 2 rely on replaceable miniature cell batteries, while the Charged Big OMG and Charged BigO Ritz feature integrated USB-rechargeable cells.
- Speed options vary by model. The Double Wammy operates at a single continuous vibration speed, while the Big O 2, Charged Big OMG, and Charged BigO Ritz offer multi-speed settings and pulsation patterns.
- Material dictates lubricant compatibility. The RingO Ritz and BigO Ritz utilize silicone, requiring water-based lubricants exclusively. The Double Wammy, Big O 2, and Charged Big OMG use elastomeric SEBS polymer.
- All vibrating rings require water-based lubricant. Silicone lubricant degrades silicone bands and can seep into electronic battery compartments on SEBS rings, breaking the water seal.
- Safe wear time is strictly 20 to 30 minutes. No vibrating ring should ever be worn for longer than 30 minutes per session or worn while sleeping.
- Emergency removal is simple. All five models are crafted from flexible, elastomeric polymers that can be slipped off easily or severed safely with blunt-tip scissors if trapped.

The short answer
Choose the Colorpop Big O 2 for dual motors, or Charged Big OMG for rechargeable convenience
The Colorpop Big O 2 is the most versatile dual-motor option because it adds 3-speed pulsing controls to the top motor while keeping steady base vibration. If you prefer rechargeable power over disposable button batteries, choose the Charged Big OMG for its powerful vertical motor and USB convenience. Select the O Wow Double Wammy for simple single-speed dual vibration, or the RingO Ritz if you want non-motorized constriction.

Who should choose the O Wow Double Whammy?
Choose the Screaming O Wow Double Wammy at $25.00 if you want straightforward, high-contact dual stimulation without needing to navigate complex speed settings during intimacy.
The Double Wammy positions two dedicated vibrating bullet units inside a flexible purple elastomeric band. The upper motor rests against the clitoris during penetrative intercourse, while the lower motor directs steady vibration into the base of the shaft and perineum. Both motors activate simultaneously with a single push-button toggle.
Because each vibrating bullet can be removed from its housing, cleaning the stretchy SEBS band is straightforward. The unit ships with pre-installed miniature button cell batteries that provide roughly 40 to 60 minutes of operational playtime before battery replacement is necessary.
Practical rule: keep a spare blister pack of standard AG13/LR44 button cell batteries in your nightstand drawer so play is never interrupted by a drained disposable battery.
Who should choose the Colorpop Big O 2?
Choose the Screaming O Colorpop Big O 2 at $23.00 if you want the combined coverage of dual motors with customizable rhythm patterns.
The Colorpop Big O 2 upgrades the dual-motor design by giving the upper vertical head four distinct operational modes: low speed, medium speed, high speed, and an alternating pulse mode. The bottom motor delivers a constant, steady hum that stays locked into place at the base of the shaft.
The ring band is molded from soft, ultra-elastic SEBS in high-visibility bright green. Its vertical top node provides targeted contact with minimal shifting. Like the Double Wammy, it runs on replaceable miniature batteries and should be lubricated exclusively with water-based formulas.
Buying rule: if you enjoy rhythm variations or pulsating sensations rather than a single continuous drone, the Big O 2 provides four distinct modes for $2.00 less than the single-speed Double Wammy.
Who should choose the Charged Big OMG?
Choose the Screaming O Charged Big OMG at $24.00 if you want to eliminate disposable button batteries and prefer rechargeable convenience.
The Charged Big OMG is engineered with a single vertical motor positioned upright on a thick, durable SEBS ring. This vertical orientation maintains firm contact during varied intimate positions without rolling sideways. The internal motor delivers three speeds plus a rhythmic pulsation mode, driven by an internal lithium-ion cell charged via an included USB cable.
A full charge provides over 60 minutes of continuous runtime. The motor housing is sealed to provide splashproof water resistance and operates with a quieter sound profile than miniature disposable bullets.
Who should choose the Charged Big O Ritz?
Choose the Screaming O Charged BigO Ritz at $17.00 if you want a premium silicone ring band with rechargeable bullet versatility at an accessible price.
Unlike the SEBS models, the BigO Ritz uses a ring constructed from True Silicone. The removable vibrating bullet slips into the top silicone cradle and features one-touch button activation controlling three speeds and one pulse mode. Recharging is handled via the included USB cord, delivering over 60 minutes of runtime per charge.
Because the ring band is authentic silicone, you must pair it with water-based lubricants. Silicone-based formulas will soften and damage the polymer over time.
Who should choose the RingO Ritz (Non-Vibrating)?
Choose the ScreamingO RingO Ritz at $14.50 if you want pure, comfortable constriction without vibrating motors, charging cords, or battery replacements.
The RingO Ritz is molded from ultra-soft liquid silicone, giving it exceptional stretch and a velvety surface texture that sits flat against the base of the shaft. Because there are no electronic motors or battery compartments, the entire ring is 100% waterproof, waterproof, easy to wash under running water with mild antibacterial soap.
It serves as the ideal baseline support ring, offering firm blood-flow retention with zero mechanical complexity.
Where they are identical
Every product in this comparison shares fundamental construction standards and safety guidelines:
- Soft elastomeric elasticity: None of these models is rigid or metallic. All five stretch smoothly over the erect shaft and return to their baseline diameter without pinching.
- Non-trapping safety profile: Because each ring is manufactured from soft silicone or SEBS elastomer, every model can be removed immediately by hand or cut off safely in an emergency with household scissors.
- Strict 30-minute wear ceiling: Every constriction ring, vibrating or non-vibrating, must be removed within 20 to 30 minutes of application to maintain healthy tissue oxygenation.
- Phthalate-free and body-safe: All Screaming O materials are certified free of phthalates, latex, and harmful plasticizers.
- Water-based lubricant requirement: Whether constructed from silicone or SEBS, all five rings require water-based lubricant for optimal comfort and material preservation.
What we can't confirm
- Exact motor decibel ratings are not published: Screaming O describes the Charged series as quieter than entry-level bullets, but no laboratory acoustic decibel measurements are provided.
- Battery batch lifespan varies: On disposable models (Double Wammy and Big O 2), shelf life and runtime depend on the freshness of the pre-installed button cells.
- Submersion depth ratings are not specified: While the motorized units are splashproof and cleanable with a damp cloth, no formal IPX submersion ratings are claimed by the manufacturer. Do not submerge motorized units in deep bathwater.
- Exact durometer hardness numbers are not listed: Screaming O publishes elastic descriptions rather than Shore A hardness ratings for its silicone and SEBS blends.
When should you speak to a clinician?
Remove any constriction device immediately if you experience pain, numbness, tingling, cold sensations, or if the skin of the penis or scrotum becomes pale, dusky, bluish, or purple.
Penile constriction rings work by slowing venous outflow while arterial blood enters the erectile bodies. Leaving any ring on for extended durations or falling asleep while wearing one creates an ischemic risk that can cause serious tissue injury. If a ring cannot be removed and manual rolling fails, seek emergency medical assistance immediately. For full clinical safety details, consult our silicone cock ring safety guide.
If you experience ongoing or persistent difficulty achieving or sustaining an erection, consult a qualified healthcare provider for a thorough medical evaluation rather than relying solely on constriction accessories.
Common myths
"Rechargeable rings are always more powerful than battery-operated models." Micro-bullet motors in battery rings deliver sharp, high-frequency buzzing, whereas larger rechargeable motors provide deeper, lower-frequency rumbles. Intensity depends on motor size and weight rather than the power connector alone.
"You can use silicone lubricant with SEBS elastomeric rings." Silicone oils break down SEBS polymers and degrade rubber water-gaskets around battery compartments. Use water-based lubricant for all vibrating rings.
"Vibrating cock rings can be worn for several hours." Constriction rings must never remain in place for longer than 30 minutes. Extended use restricts capillary perfusion regardless of whether vibration is active.
"Dual-motor rings vibrate with double the battery life." Dual-motor models draw power for two separate motors simultaneously from miniature cell batteries, resulting in slightly shorter battery lifespans than single-motor units.
Frequently asked questions

The Double Wammy features single-speed dual motors for continuous top and bottom stimulation. The Colorpop Big O 2 features a 4-function upper motor with 3 speeds plus pulsation, paired with a steady bottom motor.
Are Screaming O vibrating cock rings waterproof?
The motorized units are splashproof and water-resistant for surface cleaning, but they are not rated for complete submersion in bathtubs. The non-motorized RingO Ritz is 100% waterproof and waterproof for easy washing under running water.
Can I replace the batteries in the Double Wammy and Big O 2?
Yes. Both models feature removable vibrating bullets that open to accept standard miniature alkaline button cell batteries (typically AG13/LR44).
How long can I safely wear a Screaming O vibrating ring?
Safe wear time is strictly limited to 20 to 30 minutes per session. Never wear any constriction ring while asleep or under the influence of sedatives.
Which Screaming O model is rechargeable via USB?
The Charged Big OMG and Charged BigO Ritz both feature internal rechargeable batteries and include dedicated USB charging cables.
What type of lubricant should I use with these rings?
Always use a high-quality water-based lubricant. Silicone, oil-based, and petroleum lubricants can degrade silicone and SEBS elastomeric materials over time.
How do I clean and store my vibrating cock ring?
Remove motorized bullets if applicable, wash the elastic band with warm water and mild soap, pat dry with a lint-free towel, and store in a cool, dry location away from direct sunlight.
