Nano S Plus is usually read as three parts: Nano, S, and Plus. The useful point is not to overcomplicate the sound, but to keep the model name clear when comparing the Nano series, asking for accessories, or reading setup material.

Nano S Plus is read as a model name
Say Nano as a normal English word, read the letter S separately, and then say Plus. In conversation, keeping the three parts distinct helps listeners separate Nano S Plus from Nano X or newer Nano-series names.
The Nano series pronunciation guide gives a wider model-name context when the reader wants to compare how Nano names are spoken.
Spoken context matters more than a perfect accent
For most support, buying, or learning conversations, the goal is a clear model reference. A reader can say Ledger Nano S Plus first, then repeat only Nano S Plus once the product family is understood.
- Keep Ledger as the brand name.
- Read S as a separate letter.
- Use Plus to distinguish it from Nano X.
Pronunciation should not replace model comparison
Pronunciation helps communication, but it is not the same as choosing a model. The Nano S Plus usage guide is a better next step when the reader wants to understand the device workflow and setup context.
Use the name consistently in records
When saving notes, quote requests, or accessory records, write the full model name as Ledger Nano S Plus. That keeps spoken conversation, written records, and later comparison aligned without mixing pronunciation with verification tasks.
