EMF Shielding-Free Air Tube Over-Ear Headphones

EMF Shielding-Free Air Tube Over-Ear Headphones from DefenderShield.

Key features

• Zero RF at the Ear and ELF Cord Shielding for Extended Listening
• Protected under Patent License #6453044. EMF shielding performance verified through FCC-accredited lab testing.
• Plush Over-Ear Comfort Built for Longer Sessions
• Getting Set Up
• Choose the version that matches your device
• For devices with a USB-C port, check device settings to ensure it is an audio and microphone-enabled analog USB-C port. Many are just charging ports or audio-output only.
• Fitting and Comfort
• Adjust the headband sliders so the band rests on the crown of your head — not on top of your ears.
• If the band is too long , the cups may sag and lose their passive seal.
• Make sure your entire ear sits inside the cushion cavity . If the padding rests on your ear cartilage instead of around it, discomfort may develop during longer sessions.
• If you wear glasses, check that the frames do not lift the ear cushion away from your head. A broken seal can reduce both comfort and passive sound isolation.
• For Maximum EMF Reduction

Compatibility

• 3.5mm TRRS / 4-pole — audio + microphone + inline controls on compatible ports and adapters
• Analog USB-C audio with microphone on compatible devices
• Adjustable — fits a range of head sizes
• If your earbuds aren’t working, often the earbuds are not defective but the device, port, or adapter you are using. Even if the port looks correct, it may not be compatible.
• The earbuds should work on most devices (with the correct adapter if needed) for audio connections, while the mic and controls may be less universally compatible.

Specifications

• Available in 3.5mm for broad device compatibility and USB-C for newer devices, including iPhone 15 and newer, Google Pixel, and newer Samsung models.
• Plug the cord into your device and set the volume below 65 dB before putting the headphones on. Start low and raise gradually to a comfortable level.
• 0.81 lb (367 g) — both variants
• 8 × 7.25 × 3.5 in (203 × 184 × 89 mm)
• 42.5 in (108 cm) — plug to speaker housing
• 5 in (12.7 cm) — speaker housing to headset
• Connector — 3.5mm
• Compatibility — 3.5mm Version
• Any device with a true 3.5mm TRRS / 4-pole headset jack (if a device has both ports, go with the 3.5mm)
• Use the 3.5mm version with a Lightning-to-3.5mm adapter that supports headset + microphone (TRRS / 4-pole)
• USB-C or Lightning adapters for 3.5mm port
• If devices have multiple port options, the 3.5mm earbuds have the most universal audio and mic connection.
• 3.5mm Headphones Information
• Our 3.5mm headphones include a microphone, which requires a TRRS (4-pole) connection.
• Confirm your device supports TRRS (4-pole) 3.5mm jacks for audio and mic (input and output).
• You can purchase a 4-pole TRRS 3.5mm adapter, just make sure it says “supports headphone and mic”.
• Passive / “Accessory Mode” : Relies on the device to output analog audio through USB‑C just like a 3.5 mm jack would.
• Android phones with a 3.5mm and USB-C port (Moto G Stylus 5G) don’t support any USB-C audio

What it does not do

• TRRS (4-pole) = audio + mic + controls. TRS (3-pole) = audio only — mic and controls will not work
• TRS (3-pole) → audio only (mic and controls will not work)
• Cheap or generic adapters are often just for charging (audio and microphone/controls won’t work) or audio (microphone or controls won’t work).
• Audio works but microphone doesn’t
• Likely wrong adapter (TRS instead of TRRS) → use TRRS/4-pole adapter. It must include a DAC if adapting to USB-C or Lightning (cheap pass-through adapters won’t work).

Care

• Wipe the ear cushions with a soft, damp cloth after use.
