Woojer Strap 4 Wearable High-Fidelity Haptic Audio Device for VR, Gaming, Music and Movies

Feel entertainment through powerful, high-fidelity haptic feedback with the Woojer Strap 4. This lightweight wearable converts audio into detailed physical sensations, adding another dimension to games, virtual reality, music, movies, workouts, and relaxation sessions.

Its patented Osci V2 TRX haptic transducer operates across a 1–250 Hz frequency range. Bluetooth 5.0, USB-C audio, and 3.5 mm line-in connections support flexible use with compatible phones, computers, game consoles, VR headsets, and audio equipment.

High-Fidelity Haptic Feedback

The Osci V2 TRX transducer transforms low-frequency audio information into precise tactile sensations. Feel bass lines, vehicle engines, explosions, environmental effects, and cinematic soundtracks directly through the wearable strap.

The 1–250 Hz response range supports more detailed sensations than a basic rumble effect, while the quiet operating design helps keep attention on the content.

Gaming and VR Immersion

Connect the Strap 4 to a compatible gaming system, computer, phone, or VR headset to feel supported audio cues during gameplay. Haptic feedback can add physical impact to racing, action, simulation, rhythm, and virtual-reality experiences.

Connection method and feature availability depend on the ports and audio capabilities of the source device.

Music and Movie Experience

Wear the Strap 4 while listening to music or watching movies to feel bass, rhythm, effects, and soundtrack dynamics. Independent haptic controls let you adjust the physical sensation separately from headphone volume.

Dedicated Woojer App

The Series 4 application provides access to compatible device controls, including:

• Appearance settings

• Basic device functions

• Audio settings

• Firmware updates

Bluetooth Low Energy supports app communication and compatible firmware-management features.

Built-In Headphone Amplifier

A Texas Instruments analog headphone amplifier delivers up to 138 mW into 16-ohm headphones. The 3.5 mm output supports stereo headphones and TRRS microphone-equipped headsets.

Rechargeable Portable Design

The integrated lithium-ion battery provides up to 10 hours of use, depending on volume, haptic intensity, connection method, and other operating conditions. USB-C charging takes approximately three hours, and automatic shutoff helps conserve battery power.

Why It Stands Out

The Strap 4 combines a wide-range haptic transducer, integrated headphone amplifier, multiple wired and wireless connections, app control, and a rechargeable portable design. It delivers tactile audio without requiring a chair-mounted or room-based haptic system.

Setup and Use

Adjust the strap for a secure, comfortable fit, then connect it to a compatible audio source through Bluetooth, USB-C, or the 3.5 mm input. Begin at a low haptic-intensity setting and increase gradually to a comfortable level.

Charge the device with the included USB-C cable. Keep the unit dry and follow the manufacturer’s instructions for connection, charging, firmware updates, and cleaning.
