The Woojer Strap 4 turns sound into a physical sensation you can feel, so music, games, movies and guided meditation reach you through your body as well as your ears. It’s the brand’s most compact vibroacoustic wearable, and as North America’s specialist sensory store, we’re proud to bring this portable haptic audio device to families, educators and therapy teams.

Wear it around your waist, across your chest or cross-body, then choose what you’d like to experience. A teen might feel the bass line of a favorite track, while an adult unwinds with a breathwork session after work.

Key Features of the Woojer Strap 4 Wearable Haptic Device

• Patented OSCI Haptic Technology - Reproduces low-frequency audio as detailed, body-felt vibration, so each beat and rumble arrives as a clear physical sensation.
• 1-250 Hz Haptic Frequency Range - Covers the deep end of sound where rhythm lives, helping users connect with the pulse of music, games and soundscapes.
• Bluetooth 5.0 Connectivity - Pairs wirelessly with compatible devices, so setup stays quick at home, in a classroom or in a multi-sensory room.
• USB-C Digital Audio - Gives you a wired digital connection when wireless isn’t the right fit.
• 3.5 mm Audio Input - Accepts a standard audio cable, so everyday audio sources can drive the haptics.
• Bluetooth Headphone Support - Sound plays through the listener’s own headphones while the strap handles vibration, keeping audio personal in shared spaces.
• Independent Audio and Haptic Control - Volume and vibration intensity adjust separately, so each person can settle on the sensory input that feels right.
• Adjustable Wearable Fit - Sits at the waist, across the chest or cross-body, letting every user pick the position that’s most comfortable.
• Lightweight Build at Approximately 240 g - Comfortable for a full session and easy to carry between rooms in the included pouch.

How Body-Felt Sound Supports Relaxation and Sensory Exploration

Vibroacoustic input pairs what we hear with what we feel. That extra tactile layer can make sound easier to connect with, whether someone wants energy for a workout or a slower rhythm for meditation. It’s welcoming for neurodiverse and neurotypical users alike, and occupational therapists may find it a flexible option within a sensory diet. Woojer positions the Strap 4 as a wellness product, not a medical device.
