The Kali Audio HP-1 multi-reference studio headphones w/BT is built for engineers, mixers and creators who demand honest playback in every session. Closed-back, around-the-ear earcups block out distractions with active noise cancelling. Three switchable voicings—studio, consumer and bass heavy—let you check your mix across different listening environments. Bluetooth connectivity means you can QC tracks on your phone or work cable-free. The 40 mm drivers deliver full-range sound from 18Hz–22kHz, with 17 ms latency for real-time monitoring. A 40-hour battery, folding design and built-in mic make this headphone a solid choice for long sessions, remote calls or travel between studios.
Selectable Reference Voicings Simulate Real-World Listening
The HP-1 includes three voicing modes: studio, consumer and bass heavy. Studio mode delivers a neutral response for critical listening. Consumer and bass heavy modes mimic the tuning of common headphones used by everyday listeners and hip-hop fans. Pressing the power button cycles through each mode, so you can hear how your mix translates outside the studio. This feature gives engineers a fast reality check without switching gear.
Active Noise Cancelling and Closed-Back Isolation Enhance Focus
Active noise cancelling circuitry filters out background noise while the closed-back, over-ear design blocks distractions. The 40 mm drivers stay focused on your mix, free from outside sound. Extended sessions in noisy rooms or on the go stay productive. This isolation lets you zero in on subtle details, even in less-than-ideal environments.
Bluetooth and Wired Options Expand Connection Choices
Bluetooth connectivity supports AAC and SBC codecs for clean wireless audio. Onboard controls manage playback, calls and track navigation. Wired use is easy with the supplied 3.5 mm cable and 1/4" adapter. USB-C charging provides fast power-ups and over 40 hours of use per charge. This flexibility keeps the headphones ready for studio work or mobile production without downtime.
Lightweight Construction and Replaceable Parts Increase Longevity
The HP-1 weighs just .4 lb. and folds down for storage in the included case. Circumaural pads fully enclose your ears for comfort over long periods. Replaceable earpads ensure years of use, while the build quality holds up to travel, setup and teardown. These headphones withstand daily use and remains comfortable for marathon mixing days or repeated commutes.
HP-1 Headphones Delivers Reliable Studio Insight
Mix engineers and producers who rely on accuracy use the HP-1 headphones for critical and reference listening. The three voicing modes and noise cancelling features reveal every detail of a track, while the lightweight build and long battery life make it easy to use all day. Confidence in translation and comfort during long hours lead to better results with every session.
