The test
1. General Information
We made an anonymous purchase of these KLIM wired headphones on Amazon France. As an independent testing institute, we carefully evaluated this product, from ordering to use.
It is important to note that our evaluations are in no way influenced by brands. Brands pay for an audit of their customer experience and for the use of our trust badge, but are not informed when we place an order.
Our assessment covers the entire customer journey, from product presentation to delivery and acceptance. We also analyze packaging, user experience and after-sales service, while assigning a value-for-money score compared with other market players.
Assessments are based on a points system, with a maximum of 100 points per section. The final grade is the average of the sections, weighted according to their importance. Details of our assessment process are available on our website.
2. Delivery (out of 100 points)
ℹ️ Delivery testing provides accurate information on the time, condition and reliability of delivery services offered by brands. Consumers want to be sure that their products will arrive on time and in good condition. By testing delivery processes, we can identify weak points, whether delays, damage or communication problems.

Product protection | Sturdy, suitable packaging, resistant to simulated impacts | 100/100 |

5. Practical test: Does the brand deliver on its promises?
ℹ️ In this section, we document the results of our practical tests and determine whether products deliver what brands promise. Are marketing arguments and advertising promises well-founded?
Observed criteria | Remarks |
“Memory foam ear tips that fit your ears perfectly.” | Compliant: responsive and comfortable foam. |
“The magnets prevent tangling, unlike most earphones.” | Useful feature for easy storage. Flexible and practical cable, but not completely tangle-free.
|
“The best audio quality in their price range.” | Clear and balanced sound, but comparative claim requiring proof.
|
“The ear tips completely isolate you from outside noise.” | Good passive insulation, but not “complete.”
|
“Built to last.” | High-quality, sturdy design, but some customer reviews mention premature wear and tear. |
The main promises have generally been kept, but certain phrases (“complete isolation,” “better audio quality”) are more marketing hype than measurable facts.
