Woojer Strap 4
Haptics That Let You Feel the Sound
Woojer Strap 4 is a haptic strap that turns audio from games, films and music into physical sensations on your body. The patented Osci TRX2 transducer converts low frequencies into distinct pulses, letting you feel explosions, gunfire and bass. It receives audio via Bluetooth 5.0 or a wired 3.5 mm input and USB-C audio, with connection options for consoles, PCs and smartphones. We will confirm availability of the Core Black, Call of Duty and Fortnite editions in the quotation.
Feel the Bass
At the heart of the strap is a patented Osci TRX2 haptic transducer, which operates across the 1-250 Hz range. This covers the deepest bass and the most intense sound effects, from in-game explosions to the bassline in your favourite tracks. Instead of the vibrations familiar from controllers or phones, you get precise, localised impacts synchronised with sound in real time. This makes on-screen action tangible and enhances immersion whether you are playing a shooter, watching an action film or listening to music with a strong beat.

A Connection That Fits Your Device
Bluetooth 5.0 receives audio from a compatible phone or computer. PlayStation and Xbox do not support a direct Bluetooth audio connection with Woojer. Choose a wired connection for these consoles according to the instructions; the strap also supports a 3.5 mm TRRS input and USB-C audio.

Battery and Charging
Battery life and charging time require confirmation for the offered version. Results depend on usage. Charging is via USB-C with a 5 V power supply.
Headphones and Microphone
The 3.5 mm TRRS headphone output supports compatible headphones with a microphone. On PlayStation or Xbox, connect the controller, Woojer and headphones with four-contact TRRS cables. A three-contact TRS cable does not carry the microphone signal; an active Bluetooth audio stream from another device also disables it.
