To make the product name easier to remember, make it more convenient for users to purchase, and acquire better marketing effects, FiiO is going to apply new naming rules for future products since the FH15. Here are all the details about the new naming rules.

The main product name will be arranged as follows:

Product code + Upgrade code + Level code + Version code

The first letter stands for product category.

E.g., M stands for portable music players; FH stands for driver hybrid IEMs.

The second digit stands for upgrade code.

For each upgrade, the upgrade code before the level code will be added with one bit, usually using from 1 to 9 in sequence.

The third digit stands for level code.

Taking a natural number (such as 1, 3, 5, 7, 9), the larger the number, the higher level the product.

The fourth part stands for version code.

K/S/Pro/Plus/Max/EVO/BT/Mon will be used. As an alternative, the version code can be used in pairs.

Notes:

Products that have been planned and are ready to go on the market will follow the original naming rules, such as the M15S.

Best regards,
