Over-ear headphones Bitmat DNA ST PRO – wired stereo, closed-back design

Bitmat DNA ST PRO over-ear headphones provide wired stereo sound in a closed-back, circumaural design that prioritizes passive noise isolation and comfortable long-wear use. Intended for general audio playback and monitoring, these headphones use a standard wired connection to ensure compatibility with most portable players, computers and audio equipment. The closed-back shell helps reduce room bleed and external noise while maintaining a focused listening experience.

Advantages

The closed-back construction offers effective passive isolation without the need for active noise cancelling, making these headphones suitable for use in moderately noisy environments. Circumaural ear pads distribute pressure around the ear for improved comfort during extended sessions. A wired stereo connection delivers consistent signal transmission and broad compatibility with existing audio sources and interfaces. The design balances practical durability and everyday usability for general listening and monitoring tasks.

Suitable for

• Everyday music listening with portable players and smartphones (via compatible adapter)
• Home and desktop audio playback with computers and media players
• Basic monitoring and reference listening for casual audio work
• Travel and commuting when passive isolation is required

Key specifications

How to use

Connect the headphone plug to the headphone output of your portable player, computer or audio device. Adjust the headband and ear pads for a secure, comfortable fit that fully encloses the ears to maximize passive noise isolation. Play audio from your source device and set the playback volume to a moderate level before increasing to a preferred listening level. For monitoring tasks, position the headphones so that they seal around the ears and maintain consistent placement during critical listening.

Usage recommendations

To prolong pad life and maintain sound quality, avoid exposing the headphones to excessive moisture or extreme temperatures. When not in use, store them in a dry place and disconnect the cable if detachable to prevent strain. For consistent monitoring results, allow a short warm-up period after powering on your source device and use a stable, noise-free audio source.
