2E1 Pro Ears

After numerous requests made to me from single-sided deaf gamers, musicians and audiophiles for a high fidelity headphone incorporating the 2E1 system, I am pleased and thrilled to offer my highly praised 2E1 high fidelity rated headphone models! Put these 2E1 high fidelity rated headphones over you're one ear and you will immediately feel and hear and understand why it is so well received! 

The 2E1 High Fidelity Headphone Models for Gaming and Music Listening

I build both of my 2E1 Pro Ears models (2E1 Pro Ears with gold letters & 2E1 Pro Ears Ultra Gel Folding with platinum letters) by converting the Altus Brand Pro Ears hearing protectors. The Pro Ears (Gold Lettering) model is made with genuine leather visco-elastic foam ear cushions and a leather padded headband and the Pro Ears Ultra Pro Ears model (Platinum Lettering) which is compact and foldable with comfortable, stay cool aviation gel ear cushions and a padded steel spring headband. For both my 2E1 Pro Ears (gold and platinum) models I incorporate the legendary Koss KSC75 high fidelity stereo headphone drivers that I mechanically attach to an acoustic diaphragm that is arranged inside one ear-cup in my unique and innovative Flying Echelon™ staggered drivers configuration for aiding a single-sided deaf person's stereo panning perception.

• Stress relief of the soldered wired connection to the drivers for added wired connection durability is standard on all models
• 60 Ohms Impedance (Headphones with high impedance (25+ ohms, approximately) tend to need more power to deliver higher audio levels. High impedance protects from damage caused by overloading and can also be used with a wider range of audio equipment but may require a headphone amplifier pairing for low voltage devices like portable music players, smartphones & wireless gaming controllers, etc. to achieve optimum audio performance.)
• 101 dB SPL/1mW Sensitivity (The consensus is that exposure to sounds louder than 85 to 90 decibels over an extended period of time can contribute to hearing loss so please always keep your listening volume at a safe level.)
