Application Scenarios

- Standard meeting room of four to six people at three to five metres
- Boardroom pick-up to about six metres with the 6 microphone array
- Work from home and business travel where the unit runs on its own battery
Problems It Solves
- Headphones are charged more often than they are used400 and 450 mAh cells give 45+ and 50+ hours of playback at 70 % volume, from a 1.5 hour charge.
- Plastic headbands crack in a school bagAn internal metal headband under a smooth PU finish carries the load rather than the plastic shell.
- Children's hearing is a compliance and trust questionThe kids models cap output at 85 dB, so the limit is in the hardware rather than an app setting.
- One size does not fit a growing childThe adjustable, foldable headband extends as the child grows and folds flat for transport.
Materials And Manufacturing
An internal stainless steel headband carries the load, finished with a soft PU exterior and a smooth-finish headband. Ear cups are foldable, and the adult models rotate to fit different heads.

Use Guide
How to specify and evaluate this model before you commit to an order.
Specifying It
- Decide adult or kids first — the 85 dB limit changes the amplifier stage.
- Confirm whether a wired fallback is required; the braided 110 cm cable is included as standard.
- Pick playback time by use case: 45 hours for commuting, 50 hours for long-haul and classroom carts.
- Send Pantone references for the two-tone colourway at quotation stage.
Evaluating The Sample
- Check the published figures against the sample rather than against the datasheet
- Test at the volume and distance your customer will actually use
- Confirm the finish and print in the light of your retail environment
- Run the packaging drop before you approve the carton
- Agree the retained approval sample as the production reference
