Excellent
Très bon, le son est équilibré, tout y est, ils sont légers et tiennent bien. Il faut être fou pour dépenser plus. De loin les meilleurs dans 5 models d'autres marques que j'ai essayés.

Very good but...
Nice design and operates well instead of my first views that the sound was linear, after a few more tests with another aet that is proven to be linear or neutral, it was fond to have less bass and more trebles with standard audio spatiality as expected. This means this is an overestimated low-price product, even if the quality is very good

Good vibrant sond
The parcel has been received in around 1 week using slow delivery to Greece with no problems.
Nice box design and a earphones with a simple pouch they are not a IEM model but standard plug in earphones. The remain design ensures a IEM type of cabling and plug.
Tested in the road rthe same day with a old type DAP they delivered a quite trebly sound as with any other tested earphones so far, The original recordings have lots of treble as like Dolby cassettes in which the Dolby option is not used! Using other more linear recordings the sound is heard very close to the original I hear in my stereo. All fidelity is herd from the lowest possible level compared to the other earphones!
Replacing the buds with comply types added a few db of bass making the sound more vibrant!
Very good
