How PoM Shield PLUS Works
The PoM Shield PLUS is a faraday bag with a unique feature: an external antenna that keeps your phone connected while containing EMF radiation away from your body.
When you place your phone in the PoM Shield, the shielded enclosure blocks EMF from reaching you. But unlike traditional Faraday bags, a cable routes the signal to an external antenna that you position up to 5 meters away—wherever you have good reception. Your phone connects through this antenna, not through airwaves near your body.
The result: your phone works normally (calls, texts, data, WiFi) while the EMF source is physically separated from you. You can even charge your phone inside the shield or connect wired headphones to take calls.

For bedroom use, a single antenna can connect to two PoM Shields—useful for couples who both want protected phones at night.
The PoM Shield PLUS ships from Greece and includes the antenna kit.
How SLNT Faraday Phone Sleeve Works
The SLNT Faraday Phone Sleeve is a complete Faraday cage that blocks up to 100% of all wireless signals when your phone is inside.
Using SLNT’s military-grade Multishield material (MIL-STD-188-125-2 compliant), the sleeve creates a shielded enclosure that no signal can penetrate. When you slip your phone inside and close the magnetic closure, your phone becomes invisible. No cellular, WiFi, Bluetooth, GPS, or any other wireless transmission can reach it.
This makes your phone untraceable and unhackable until you remove it. Location tracking stops. Remote access becomes impossible. Your phone is effectively offline.
| Size | Internal Dimensions | Fits Phones |
|---|---|---|
| Small | 5.5″ x 3.5″ | Smaller phones |
| Medium | 6.7″ x 4.5″ | Most phones |
| Medium Plus | 7.6″ x 4.8″ | Large phones with cases |
The front slip-in pocket (non-shielded) provides storage for cards or small items. The weatherproof nylon or premium leather exterior offers durability for everyday carry.
The SLNT Faraday Phone Sleeve is available in multiple sizes and materials.
Head-to-Head Comparison
Protection Approach
PoM Shield creates a Faraday cage around your phone, then routes signals through an external antenna positioned away from your body. You stay connected; EMF stays distant.
SLNT Sleeve creates a Faraday cage with no signal routing. Your phone is completely isolated, protected from external signals and unable to transmit anything. Total privacy, zero connectivity.
Connectivity
With PoM Shield, your phone works normally. Calls ring, texts arrive, apps function. You’re just not exposed to the EMF because it’s redirected to the antenna up to 5 meters away.
With SLNT Sleeve, your phone is offline. Nothing gets through. To use your phone, you remove it from the sleeve, which re-exposes you to EMF but restores full functionality.
Use Cases
PoM Shield is ideal for EMF-sensitive users who still need their phone accessible—at your desk, bedside, or anywhere you spend extended time. The antenna creates distance without disconnection.
SLNT Sleeve is ideal for privacy and security when you need to ensure your location isn’t tracked, your data can’t be accessed remotely, or you want to go genuinely off-grid with your electronics.
Complexity
PoM Shield requires initial setup: positioning the antenna where reception is good, routing the cable, and understanding the system. Once set up, it’s seamless, but there’s a learning curve.
SLNT Sleeve is instant: slip phone inside, close the magnetic flap, done. No setup, no configuration. The tradeoff is that you can’t use your phone while it’s protected.
Best For: EMF Protection While Staying Connected
If you’re concerned about phone EMF exposure but still need your phone accessible, the PoM Shield PLUS offers a unique solution.
The PoM Shield works well if:
- You’re EMF-sensitive and want to minimize exposure
- You need your phone to receive calls and messages
- You work from home and want to keep your phone away from your body
- You want overnight protection while staying reachable for emergencies
- You prefer a permanent setup rather than constantly putting your phone in and out
The PoM Shield is particularly valuable for bedroom use, where you can position the antenna away from your sleeping area while keeping your phone connected for alarm functions or emergency calls.
Best For: Privacy, Security, and Going Off-Grid
If you need guaranteed signal blocking—for privacy, security, or simply disconnecting, the SLNT Faraday Phone Sleeve provides certainty.
The SLNT Sleeve works well if:
- You want to be certain your phone can’t be tracked
- You carry sensitive information and want to prevent remote access
- You need to go “off grid” in certain situations
- You value simplicity—just slip phone in when needed
- You want a portable solution for travel
The SLNT Sleeve is particularly valuable for travel EMF protection through sensitive areas, meetings where electronic eavesdropping is a concern, or any situation where you need to guarantee your phone is completely isolated.
Best For: Different Scenarios
Because these products solve different problems, some users benefit from both:
- PoM Shield for home/office: Keep your phone accessible but EMF-distant during work hours
- SLNT Sleeve for travel: Complete isolation when moving through airports or unfamiliar areas
- PoM Shield for sleep: Stay reachable for emergencies without overnight EMF exposure
- SLNT Sleeve for meetings: Guaranteed privacy when discretion matters
Common Misconceptions
- All phone pouches block EMF the same way: The PoM Shield PLUS redirects EMF via an external antenna while maintaining connectivity. The SLNT Sleeve blocks all signals entirely. These are fundamentally different approaches.
- You can’t use your phone inside a Faraday bag: This depends on the product. The PoM Shield PLUS allows calls and texts through its antenna system. Traditional Faraday sleeves like SLNT do block all use.
- Faraday bags drain your battery faster: While phones in traditional Faraday bags may search for signals and drain faster, the PoM Shield PLUS maintains a connection through its antenna, avoiding this issue.
What They Don’t Do
Understanding the limitations helps you choose correctly.
PoM Shield PLUS does not:
- Block all signals (that would defeat its connectivity purpose)
- Work without proper antenna positioning
- Provide instant on/off signal blocking (it’s a stationary setup)
- Make sense for users who don’t mind regular phone exposure
SLNT Faraday Phone Sleeve does not:
- Allow any phone functionality while inside (complete signal block)
- Provide EMF protection during active phone use
- Work for users who need their phone always accessible
- Require any setup (which is a feature, not a limitation)
Both products are Faraday-level protection. The difference is whether signals are redirected (PoM Shield) or completely blocked (SLNT).
Frequently Asked Questions
PoM Shield PLUS ($149) redirects EMF up to 5 meters away while keeping your phone usable, allowing calls, texts, and charging. In contrast, SLNT Sleeve ($80-$100) blocks all signals completely, requiring you to remove the phone for any use.
If you require total isolation from signals for privacy, the SLNT Phone Sleeve is ideal as it blocks up to 100% of all signals completely.
Yes, with PoM Shield PLUS, your phone remains usable and can be charged while inside due to its external antenna that maintains connectivity.
The SLNT Sleeve is simpler to use as it only requires slipping your phone inside, whereas PoM Shield PLUS needs proper antenna positioning for optimal performance.
PoM Shield PLUS redirects EMF away while maintaining phone usability and connectivity via an external antenna, making it safer for those concerned about EMF exposure but needing to stay connected.
