The Sound Professionals HP-1 custom designed monitor headphones offer pro-grade build quality and audio performance for Court Reporting and editing, professional studio-based production, location recording, DJing, podcasting, and critical daily listening.

Outfitted with 40mm large-aperture dynamic drivers and an over-ear, closed-back design, the HP-1 headphones deliver clarity, deep bass, and extended bandwidth (10 Hz to 24 kHz) while isolating you from outside sounds.

The headphones are both durable and comfortable to wear. Two detachable, single-sided cables—one coiled and one straight—are included for optimal operation.

Each cable sports a gold-plated 3.5mm mini plug for use with mobile devices and computer soundcards, and a 1/4″ screw-on adapter is included for easy hookup to professional audio interfaces, mixers, and stereo receivers. A carrying case is supplied with the HP-1 for convenient storage and transport of the headphones.

40mm Drivers – The HP-1 features 40mm large-aperture dynamic drivers with rare earth (neodymium) magnets and CCAW (copper-clad aluminum wire) voice coils for high-quality sound reproduction.

Tuned for Clarity and Deep, Accurate Bass – The drivers and headphone design work together to provide a sonic signature tuned flat for exceptional clarity throughout an extended frequency range along with deep, accurate bass character. With a frequency response of 10 Hz to 24 kHz, the HP-1 can reproduce a full spectrum of tones.

Over-Ear, Sound-Isolating Design – The HP-1 utilizes a circumaural design that contours around the ears for excellent sound isolation in loud environments. This over-ear, closed-back style is optimal for reducing bleed and separating you from outside sounds.
Two Detachable Single-Sided Cables – To expand its versatility, the HP-1 incorporates a detachable cable design that exits from the left side. This enables convenient cable swapping and makes it easier to distinguish the different sides of the headphone. Two cables are included—a coiled cable and a straight cable – to let you choose the best cable for working in Court, editing sessions, traveling, or listening at home.
3.5mm Plug and 1/4″ Screw-On Adapter – The attached cable is terminated with a gold-plated 3.5mm TRS mini plug for easy hookup to mobile devices, MP3 players, and computer headphone jacks. A secure 1/4″ screw-on adapter is included for compatibility connectivity with audio interfaces, mixers, and dedicated headphone amplifiers. Built-in strain relief on the 3.5mm mini plug reduces the likelihood of damaging the connection if the cable is pulled.
Pro-Grade Build Quality – Thanks to the pro-grade earpad and headband materials used in the HP-1, the headphones provide increased durability and comfort while delivering enhanced audio and effective isolation.
