Planar Audio Explained

Planar magnetic drivers deliver a precise sound better than conventional speakers

Planar magnetic speaker technology outperforms traditional speakers. By suspending a diaphgram with a printed circuit in between two magnet arrays and energizing the circuit through an audio signal, you get an electromagnetic force that moves the diaphragm creating sound.

Our exclusive rectangular drivers not only allow us to make a 66mm large diaphragm but flex more evenly, minimizing distortion and delays resonance to increase acoustic accuracy.

High End Studio Audio Experience On Mobile.

The HELM boost cable is the world’s first portable in-line amp cable.

The HELM Boost Cable brings portability to traditional amplifiers normally used to power high-end audiophile headphones like the HELM Studio Planar. Using THX’s AAA™ lowest distortion amplifier we are turning headphones in to a self-powered high-end portable solution compatible with your mobile devices and your favorite headphones.

The HELM Boost Cable is an all-in-one in-line amp cable solution delivering maximum volume (up to 12db gain), improved sound quality (true linear amplification) and serious bass enhancement (separately controlled up to 6db).
