This page does not review anything Geshelli 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 |
|---|---|---|---|
| Geshelli Archel Pro | 1.8 W | 0.1 Ω unverified | 1.5 µV unverified |
| Geshelli Archel 3S Pro | 1.0 W | not published | 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.
Geshelli publishes a power figure at a stated load on 1 of 2, output impedance on 0, a noise figure on 0. Of the 8 power figures this site displays for them at 32, 150, 300 and 600 Ω: 4 worked out by holding output voltage steady across loads, 4 not traceable to any document of theirs. 1 of their entries here predate the sourcing rule and carry figures from independent measurement rather than from a document; those are marked unverified above and counted as unpublished.
Very little of what this site says about Geshelli came from them. That is not an accusation about how their products sound — it is a statement about their paperwork, and it is the reason those pages carry so many qualifiers.
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.
