General presentation of the Vocal Vest® 2

In the world of voice picking, the Vocal Vest® is a small revolution which is generating huge interest. This unique item of high-tech work clothing is the final result of an intense R&D effort, including live trialing and input from high numbers of end-users. More than 1250 hours and € 200.000 were invested in the design and manufacture of first prototypes.

Current voice solutions using standard headsets face problems that can be difficult to overcome when implementing them in new industrial sites or warehouses. Users of single-ear headsets regularly complain about :
  • Discomfort, headache or earache, disorientation due to sound imbalance ;
  • High levels of fatigue at the end of the workday ;
  • Danger when driving forklift trucks due to excessive concentration on one ear, reducing awareness of ambient noise and other surrounding dangers ;
  • Social exclusion.
  • Long-term Bluetooth headset users may face medical issues.

If one or more of these problems occur, VOCAL VEST® 2 is a great alternative to traditional headsets. Providing a high level of comfort and ergonomics, the 2nd generation Vocal Vest significantly extends the usefulness of voice solutions by bringing new and improved working conditions for more users.

The vest was developed in close association with a large number of users of voice solutions, various CHSCTs, occupational medicine departments and representatives of trade unions, managers and warehouse directors of major French groups.

How does VOCAL VEST® 2 work ?


The equipment consists of two main components: the VOCAL VEST® 2 and the AMPLIBOX® 2
- The VOCAL VEST® 2 is like a shoulder-mounted headset with 2 loudspeakers

  • The screw-on microphone can be installed on either the right or left side
  • Size is suitable for everyone from XS to 3XL thanks to its adjustable waistband
  • The AMPLIBOX® 2 can be clipped in 6 different positions with 4 orientations per position
  • Numerous cable management systems allow for highly personalised ergonomics

- The AMPLIBOX® 2 is an interface between the vest and most devices for voice solutions

  • It enhances the sound so that it is loud and clear enough for both loudspeakers
  • Specific presets for each voice terminal are available, making the AMPLIBOX® 2 "plug & play"
  • Customer-specific presets are also possible (e.g. volume limitation)
  • Each user can adjust the volume directly on the AMPLIBOX® 2 and even mute the microphone
  • There is no screen on the AMPLIBOX® 2 and all menus and sub-menus are voice-activated

Amplibox® 2 settings


The self-powered AMPLIBOX® 2 amplifies the sound of the voice terminal to send it to both speakers, while offering the possibility of multiple audio settings. All settings can be made via the 4 buttons on the front panel of the AMPLIBOX® 2, with menus and actions announced directly through the headphones. A multicoloured LED also indicates different states, such as the microphone pausing (in order to mute it momentarily), or low battery level (also announced via the speakers).
The AMPLIBOX® 2 settings are as follows :

  • Volume
  • Microphone test
  • Microphone input setting (microphone sensitivity according to the sound environment - e.g. ambient music)
  • Microphone output setting (sensitivity of the sound sent to the voice terminal)
  • 13-track equalizer (eliminates parasitic sounds in headphones)
  • Settings presets (basic settings depending on the type of voice terminal)
  • Pause the microphone directly on the vest

Thanks to the new Bluetooth setup function and the application (nextly downloadable here on the website, in the Support / AMPLIBOX® 2 configuration section) that can be installed on an Android smartphone, the AMPLIBOX® 2 can also be set up much more easily and quickly. After connecting the AMPLIBOX® 2 and the smartphone via Bluetooth, simply go to the related section of the site (Support / AMPLIBOX® 2 Configuration / Settings entry), select your voice device, choose the language and other options to generate a QR code and scan with your Android smartphone. In this way the Amplibox® 2 is updated in less than 5 seconds.
