Serioux ZO110 are some cheap headphones, having a price around 4 euro or even lower. What is interesting about these headphones is the catching system, “Around Ear”. They will get attached to the ears and not inserted in the ears.
The ear attaching system works like this. Turn the white plastic for the ear towards you, and attach it. The correct position is with the Serioux logo (the eagle) looking behind you.
This attaching system is interesting but the materials used for it are very fragile and will break sooner or later.
The design is not bad even though it looks and feels cheap.
Sound quality. Is not good. On a scale from 1 to 10, the sound gets a 4. Even when using the Serioux ZO110 connected to a smartphone or to a PC with high quality audio rendering, the sound is still bad.
Serioux ZO110 is a good choice if you are looking for something very cheap, they are great for jogging, testing devices etc. They are definitely not some good headphones for listening music though.
