My Verdict

Perfect for beginners looking to test the waters of a new play style safely. The high-quality silicone is easy to clean and use while accommodating a wide range of sizes (5mm - 10mm diameter). While the friction of silicone keeps the use-time low without irritation, the trade off of safety for beginners and a gentle stretch for the more advanced makes these rods a must-have in any sounding kit.

Buy, if you...

  1. Are a beginner looking to try sounding but glass and steel are intimidating
  2. Have experience in this kink and want to stretch to the next size up
  3. Looking for a sound that is more discrete than glass or steel

Don't buy, if you...

  1. Want to sound for long periods of time - get steel/glass instead
  2. Are an advanced user and need something larger than 10mm or longer than 23cm
  3. Don't like the color blue (what's wrong with you??)

Just over 8 inches in length and very flexible, each of these rods can help expand your boundaries.

Personal Experience

My Personal Experiences with Master Series Invasion Silicone Urethral Sound Trainer Set

Simple, elegant, and unassuming, silicone sounds to the untrained eye resemble nothing more than rubber noodles. But for those more informed and sexually aware these innocent noodles offer a unique and exciting experience on paths rarely trod. Mine arrived in the mail a few days ago and, after a hasty but thorough preparation, I held my tube of sterile lubricant in one hand and the smallest of the three rods in the other. I applied a generous coating and lined up the tip. After a nervous breath I began the plunge, watching mesmerized as inch after inch slowly disappeared inside of me. Half way through the size increased, I felt the sudden expansion, and I gasped only pausing for a second. New sensations arrived unbeckoned as end reached deeper. All too soon the sound reached its limits. I paused to take in the sensations. I wanted more. I had two more sizes to play with. As I withdrew the first and smallest sound I felt a sense of emptiness. I quickly lubed up the second larger sound and began the plunge again.

The Master Series Invasion Silicone Urethral Sounds come in a set of three different size sounds. I like that there is a nice size variation, allowing for a gentle increase in stretch as you progress through the sizes. Each one also increases in diameter around the halfway mark, which is great for warming up and keeps things exciting as you move the sound deeper. They come in a bright blue color.

Ease of Use

Master Series Invasion Silicone Urethral Sound Trainer Set Ease of Use

A cardinal rule for any urethral play is the meticulous cleaning of the instrument, both before and after use. Proper lubrication is equally crucial to ensure a comfortable session. The initial insertion of the silicone rod is a notable experience and should be approached at a pace you're comfortable with. It's important to note that silicone, despite its many benefits, does create more friction compared to steel. For first-timers, I recommend a cautious approach, limiting initial usage to no more than five minutes. Overextension can result in a temporary burning or stinging sensation during urination, a sign of irritation rather than infection. This discomfort typically subsides substantially within two hours and resolves completely within 12 hours.

Quality

In the world of sex toys you get what you pay for. These are not the cheapest sounds in their category and the quality shows. These are well worth what they cost.

Performance

Master Series Invasion Silicone Urethral Sound Trainer Set Performance

I am personally a fan of steel sounds and have quite a collection so, when I saw there was a silicone option by a brand I respect, I needed to try it out. I was not disappointed. What makes steel sounds so great is their low friction allowing longer play sessions without causing irritation. Steel’s downside is its rigidity – a straight rod down a curving path can only go so far without risking damage to the path. Enter Master Series’ Invasion Silicone set. These soft rods are made of quality silicone with no deformities. Silicone is innately poreless (body-safe) meaning it is easy to clean and does not harbor bacteria after a thorough washing with antibacterial soap and warm water.

Packaging

The sounds come well-presented showing their full lengths and widths in a vertical clear sheath and backed by reflective aluminum easily catching the eye. The Master Series logo is emblazoned across the top - a statement piece of pride in their product. turning to the back leaves no question as to the silicone rods' use with a perfect product demonstration captured in one image, durability in the second, and product specifications absorbing the rest of the space.

If you have any fears or doubts you can always drink cranberry juice to kill any potential infection.
