20% Off myzone Voucher Codes for July 2026

The Myzone UK store separates heart rate monitors from accessories and lists products including Switch 2.0, Myzone Max, MZ-Switch, replacement chest straps, wrist straps, charging cables and a strap extender. The wider Myzone devices page explains the main device families.

A complete monitor and a replacement accessory are very different orders. Someone buying Switch 2.0 or Myzone Max may be comparing a higher-value device purchase, while an existing user may only need a strap, cable or extender. A smaller saving on the right product is more useful than a larger one attached to something incompatible.

Compatibility deserves attention before price. Myzone states that its MZ-Switch accessory straps work with MZ-Switch and are not compatible with Switch 2.0. Switch 2.0 has separate replacement wrist and arm straps in the accessories range.

Which replacement strap fits which monitor?

Myzone sells more than one replacement chest strap, so the product name matters. The replacement MZ-1/MZ-3 chest strap is listed for those two models. A separate Switch/Myzone Max chest strap is designed for MZ-Switch and Myzone Max, with Switch 2.0 also listed as compatible.

Ordering a reduced strap for the wrong device can create another purchase and a return. The model name on the module or existing equipment identifies which replacement is needed before a voucher code is applied.

The Myzone strap extender has defined compatibility too. Myzone says it clips onto the replacement MZ-1/MZ-3 chest strap or the replacement Switch/Myzone Max chest strap. It adds extra length to a compatible strap; it does not replace the monitor module.

A monitor order and an accessory order need different checks

For a complete device purchase, compare the listed saving with what is already included. The MZ-Switch package, for example, includes the module, adjustable chest, wrist and arm straps, and a USB charging cable. Buying those parts separately would not be a like-for-like comparison.

Switch 2.0 includes built-in memory for up to 36 hours of exercise data and connects to compatible equipment and apps using ANT+ and Bluetooth. Myzone lists the Switch 2.0 features on its product page.

Myzone Max is chest-based and includes a chest strap. Its product page states that it stores up to 36 hours of exercise and offers up to 300 hours between charges. The Myzone Max specifications help show whether the device suits the intended training routine before price becomes the deciding factor.

Accessory orders are usually smaller but less forgiving. A cable, strap or extender must match the existing device. The replacement charging cable is listed for Myzone Max and MZ-Switch, and Myzone advises charging it through a computer USB port rather than a 9-volt charger.

Delivery, stock and email offers

The Myzone UK store displays free mainland shipping on orders over £20.99. A single low-cost accessory may sit below that threshold, so the delivery charge should be included when comparing the final price.

Stock changes the calculation. A saving on an unavailable strap has no practical value, and switching to a different accessory without checking compatibility can create another problem. Individual product pages may offer stock notifications where available.

The shop also invites customers to sign up for new stories and personal offers. This is separate from the listings on this page. Availability and terms can change, so treat an email promotion as another option to compare rather than a guaranteed saving.

Applying a voucher before payment

Add the correct device or accessory first. At checkout, enter the voucher code in the relevant field if one is shown, then confirm that the total changes before paying.

1. Confirm the device model and accessory compatibility.
2. Add the required monitor, strap, cable or extender.
3. Review the product page for stock and any stated restrictions.
4. Enter the voucher code at checkout if a field is available.
5. Check the reduction, delivery charge and final total.

If the saving does not apply, read the terms shown with the listing. The product may be excluded, the promotion may have ended, or the order may not meet an eligibility or spending condition. The wrong size, colour or device variation can also affect the result.

Do not repeatedly submit the same voucher code without changing anything. Recheck the listing, remove any clearly excluded product and compare the displayed item price with another offer shown on the page.

How our team reviews Myzone voucher codes

Our team reviews the offers weekly and adds restrictions such as product exclusions, minimum order values and customer eligibility where they are known. Merchant terms can still change after a check, so read the details shown with each offer before paying. Our testing process explains how each saving is checked before it is added to the site.
