Knox Gear TX-100 Closed-Back Studio Monitor Headphones

Introduce your ears to a world of crystal-clear, expansive, high-fidelity audio with the TX-100 Closed-Back Studio Monitor Headphones from Knox Gear. These adjustable over-ear headphones are engineered for exceptional comfort, superior sound quality, and convenient portability anywhere you go. These headphones include a 1/4-inch adapter and feature an extra-long 10-foot cord for versatility.

Noise Blocking Closed-Back Design

Experience a crystal-clear high-fidelity audio soundscape with these closed-back headphones from Knox Gear. The TX-100s isolate your ears from unwanted external noise, preserving your bubble (and maybe your sanity) in loud environments. Closed-back headphones are the ideal listening companion when you want to isolate the most amount of external noise possible while keeping your focus dedicated solely to your audio of choice. The closed ear cups reduce the amount of outside sound that can seep in, making them the perfect choice for commuting and general noisy environments.

Powerful Bass with Clear Mids and Highs

Knox Gear headphones are engineered for maximum dynamic range and superior sound quality. 50 mm speaker unit drivers are coupled with neodymium magnets to deliver deep, rich bass, clear treble and vocals, and crisp high tones.

For Recording, Music Production, Gaming

No matter what your passion is, Knox Gear is the gear for your ears. Trusted by both audiophiles and professionals in the industry. The TX-100s are the perfect headphones for studio recording, production, gaming, and pure musical enjoyment.

Creating Better Soundscapes

Powerful 50mm drivers and neodymium magnets combine to enhance the full spectrum of your audio experience – from deep, lush basses and clear, wide mids to crisp, artifact-free high-ranges.

Comfort Makes the Difference

You won’t perform at your best or properly enjoy your music with hard, uncomfortable over-ears or earbuds. That’s why we’ve designed the TX-100 with super soft, ear-pampering ear pads and an elastic headband that adjusts to fit comfortably over any hairstyle, hat, or head shape. Whether you need headphones for all-day head-grooving, long hours in the studio, or a marathon gaming session, Knox Gear is here.

Gold-Plated Connector

Each connector is gold-plated to ensure smooth, corrosion-free connections.

Heavy-Duty Coaxial Cable

The cable is made of heavy-duty coaxial cable for each conductor. The conductors are 22AWG and each conductor is shield to prevent EMI or RFI interference from entering your audio system. The cable is 12mm x 6mm thick, while the connector housings are 41mm long x 15mm diameter.
