This page does not review anything Aune makes. It counts one thing: how much of what this database says about their products came out of their own documents, and how much had to be worked out or left blank.
| Product | Into 32Ω | Output impedance | Output noise |
|---|---|---|---|
| Aune X1s GT | 320 mW | not published | not published |
| Aune S17 Pro EVO | 2.0 W | 1 Ω | not published |
Power decides whether it gets loud enough, output impedance decides whether it tilts the response of a multi-driver in-ear, and the noise figure decides whether you hear hiss with sensitive ones. All three fit on one line of a spec sheet; most of the industry prints one of them.
Aune publishes a power figure at a stated load on 2 of 2, output impedance on 1, a noise figure on 0. Of the 8 power figures this site displays for them at 32, 150, 300 and 600 Ω: 5 printed by Aune at that exact load, 3 worked out by holding output voltage steady across loads.
Rather less than half of what this site says about Aune came from them. The rest is arithmetic, and it is marked as arithmetic on every page.
The rule used here is the same for every maker and is described on the manufacturer index. Every figure behind it can be opened on the product page it came from, with the document it came from linked.
