Choosing Kross or Duo
How do Kross and Duo differ?
Kross projects a crosshair onto a target to show head position and tilt, without an app or digital recording.
Duo adds recording for neck, trunk and limb assessments. It records the movement angle of the body segment carrying the sensor relative to the reference you set. Choose Duo to save, review or share results.
Can I see Duo before deciding?
Yes. Book a 15-minute demonstration to see the recording workflow, or send us a question about your setup, device configuration or purchase options.
What is included, and which accessories do I need?
Kross includes the device, two adjustable elastic straps, a USB charging cable and a storage box. Duo includes the device, adjustable head strap, shock-resistant storage box, USB-C cable and tilt-adjustment tool.
Package names identify any wallchart or exercise booklet additions. These are cervical resources, not requirements for every limb assessment. Third-party wrist, chest and limb mounts are sold separately. See the Duo mounting options.
Which body areas and assessments does Duo cover?
Range of Motion covers the neck, shoulder, elbow, trunk, hip and knee. Joint Position Sense and Stability and Control cover the neck, with beta assessments for the shoulder and trunk. Elbow, hip and knee currently offer Range of Motion.
How is Duo fitted for limb and trunk assessments?
Use the included head strap for neck assessments, a wrist/forearm mount for shoulder and elbow, a chest mount for trunk, a thigh strap for hip, and an ankle/lower-leg strap for knee. Compatible third-party mounts are sold separately.
The mounting position is not a separate wrist or ankle assessment. See the setup guide or ask us about your intended movement.
Is there a subscription?
No. You pay the selected Duo package price once. There is no HeadX subscription or monthly fee to use the companion app.
Can I save and share Duo results?
Yes. Save assessments on your device, review a session or group assessments into an appointment, then share a PDF report or export CSV data. HeadX does not receive your assessment records.
General
What is the HeadX Kross?
HeadX Kross is a head-mounted crosshair-laser device that provides visual feedback on head position and orientation during clinician-selected assessment and rehabilitation tasks.
What is the Kross A3 Wall Chart?
It’s a spiral-bound A3 chart that provides structured visual targets, designed to complement the HeadX Kross system.
Do I need the wall chart to use the HeadX Kross?
No. Kross can be used with a suitable target. The wall chart provides printed paths and reference targets.
Who developed the HeadX products?
All products are clinician-designed in collaboration with rehabilitation experts.
Are HeadX products safe to use?
Use HeadX products according to the supplied instructions and, where relevant, a suitably qualified clinician’s guidance. Individual suitability, exercise selection and progression depend on the assessment.
Can HeadX products be used at home?
For Kross, a clinician should decide whether home exercise is suitable and specify fitting, task, dose and progression. For Duo, follow the supplied instructions and confirm the supported recording protocol, configuration and professional supervision required.
Can multiple people use the same Kross system?
Yes, as long as straps and adjustments are set individually.
Is there training required to use the device?
No separate product certification is required, but users should read the instructions and clinicians should understand the selected assessment or exercise protocol before use.
Are replacement parts available?
Yes, please contact contact@headx.co.uk for availability.
Are downloadable wall charts available?
Yes. A4 wall charts are available as free downloads.
Do HeadX products require software or apps?
HeadX Kross provides crosshair-laser visual feedback without software. HeadX Duo connects by Bluetooth to its companion app to record angular movement and review or export individual session records.
Can I use HeadX products for children?
Only under the direction of a suitably qualified paediatric clinician, after confirming that the device and planned exercises are appropriate for the child.
Kross exercise guidance
What kind of exercises can I do with the Kross?
Examples include following a target, returning to a starting position and watching crosshair tilt during clinician-selected cervical tasks.
Can Kross provide feedback during concussion rehab exercises?
Kross can provide a visual reference during clinician-selected cervical or gaze-control tasks. Task suitability remains part of the wider professional assessment after concussion.
Does the wall chart have exercises printed on it?
It provides structured targets but not printed exercise instructions.
How do I use the laser during exercises?
The crosshair laser acts as a visual cue to follow specific movement paths.
Can I use the Kross for balance training?
It can provide visual feedback during clinician-selected gaze-stability and balance exercises. Suitability and progression should follow the individual assessment.
How long should sessions last?
Your clinician should set session length and frequency to suit your symptoms, tolerance and exercises.
Is there a warm-up required?
Not universally. A clinician can decide whether mobility preparation is appropriate for the person and the planned task.
Can exercises be done daily?
Only when daily practice is appropriate for the person and consistent with the clinician-led plan. Frequency and progression should be individualised.
Can Kross be used for selected post-stroke exercises?
Kross can provide a visual reference for selected head-movement tasks. The clinician chooses the task, support and supervision around the individual's needs.
Can Kross provide feedback during vestibular exercises?
Kross provides a visible head-position reference during clinician-selected gaze-control or head-movement tasks.
Is there an age limit for exercises?
There is no single age cut-off, but use with children or older adults should follow an individual assessment, appropriate supervision and the product instructions.
Can athletes use the Kross?
Yes, when a suitably qualified practitioner selects the device and tasks for rehabilitation or performance-related head-control work.
Do you provide exercise guides?
Yes. The HeadX exercise library offers illustrated Kross laser-guidance examples across seven chapters. A professional selects the exercises and pace of progression for the individual.
Can Kross record change over time?
Kross provides immediate visual feedback without digital recording. Duo lets you save individual angular recordings, review them side by side and export them. Keep the placement, reference, task and configuration comparable; differences in recordings are not a measure of recovery or treatment response.
Does the device replace physiotherapy?
No. Kross provides visual feedback and Duo provides angular movement records. Professional assessment, supervision and treatment planning remain separate from these product outputs.

Returns & Warranty
How do I request a refund?
Email contact@headx.co.uk with your order number and the item you want to return. Consumer online purchases have a 14-day cancellation period. HeadX also accepts change-of-mind return requests within 30 days; requests after the statutory period require the product to be unused, complete and in its original packaging. See the full return terms.
What is the refund timeframe?
We aim to process refunds within seven days. For a valid statutory cancellation, the policy provides a maximum of 14 days after we receive the returned goods or evidence that they were sent, whichever is earlier. Refunds go to the original payment method unless otherwise agreed. See the refund policy.
Are return delivery costs covered for faulty or incorrect items?
Yes. If a product is faulty or was sent in error, HeadX covers the return delivery cost.
Who pays return shipping?
The customer, unless the product was faulty or incorrect.
Can I exchange my product?
Yes, faulty or incorrect items are exchanged free of charge.
How long is the warranty?
HeadX Kross and HeadX Duo each have a 24-month warranty from the date of purchase, covering defects in materials and workmanship under normal use. This is additional to your statutory rights.
What does the warranty cover?
Defects in materials and workmanship under normal use.
What does the warranty not cover?
Accidental damage, misuse, wear and tear, or unauthorised modifications.
How do I make a warranty claim?
Email contact@headx.co.uk with proof of purchase and a description of the issue. Photos or video can help us assess it. We will confirm the next steps.
What happens if my product qualifies for warranty?
We’ll repair, replace, or refund depending on the issue.
Can I return a used product?
For statutory consumer cancellation, you may inspect the product as you would in a shop. Handling beyond what is needed to establish its nature and function may lead to a deduction if it reduces the product's value. Original packaging is not required for that right.
After the statutory period, HeadX's additional 30-day change-of-mind promise requires an unused, complete product in its original packaging. Faulty-goods rights are separate. See the full return terms.
What if I lost my receipt?
Proof of purchase is required; contact us to check your order records.
Do I get a new warranty if my product is replaced?
Contact us with the original order and replacement details so we can confirm the applicable cover. A replacement does not change your statutory rights.
Is the downloadable wallchart a paid product?
The printable A4 wallchart is a free resource. The printed A3 wallchart and exercise booklet are physical products and follow our physical-product return terms.
Does UK consumer law still apply?
Yes, this policy is in addition to your legal rights.
